Documentation usually entails the manual pages and other files like
the readme (there are news, install, changelog, release information
and other files in most software).
I would start by reading the manual pages for the sane project and the
various backends.
Try "man sane" and read to the end, there in the "See Also" section
you will find more man pages. Some URLs are also in there for
reference.

SANE is a scanner project, not a printer project (that would be
gutenprint or some other project).
/../
If you read the instructions, you will see that using configure with
BACKENDS= will create backends just for the
listed backends.
This might be useful to put in the readme, but people should also read
the general manual pages, the readme is not a substitute for them.

Hello,
Are you really reading any of the documentation? This is not IRC, so
you can't expect a loose conversation.
There is no such backend. Please read the documentation and the README
files to find out what you need to compile.

My apologies, from your messages it was not clear to me that you had
written a driver.
In that case, what you want to do is integrate your driver in SANE backends?
However, there is already a driver for this scanner family (MG3600),
so how about if you test that instead first?
It is the pixma backend, so you can just compile that backend, and
test, reporting how especially the high-resolution scans work (above
600 dpi, do you get proper image, or if not, how it looks).

Thanks Johannes,

So the question one needs to keep in mind is not USB3 per se, but
whether the xhci kernel module is being used.
I'm sorry, I need to read up more on the issue, I did not realize the
xhci module was the problem regardless of whether USB port was 2 or 3
(assuming the labelling on the ports is not wrong).

Hello Humphrey,
Thanks for the chip info (no idea about any of them unfortunately).
It would help if you could make a very small scan, the smallest you
can obtain (probably about 4mm by 4mm using the Canon-supplied Windows
TWAIN driver interface), at the lowest resolution (probably 75dpi) in
black and white, or greyscale or color in case other types not
available.
Then zip it and send to my email (aikishugyo at gmail), if there is

if the scanner supports the PIXMA protocol, there is hope (support
pretty much guaranteed). Otherwise not much.

Important information inadvertently left you!
I meant taking a USB log of the traffic of a Windows-based scan.
For WinXP, UsbSnoop is good, because I have a parser for that.
For later versions of Windows, I guess you could you use Wiresharp
with UsbPcap, looking at the output in Wireshark would work for me
too.

Hi,
Just a comment: This is already fixed more than a year ago, so if you
need this then you can install the source, or wait for 1.0.25 to be
released and be available in your distribution.

If you search the sane-devel mailing list, there are some posts in the

The very old (sane-backend 1.0.18) info collected is here:

Hi,
Thanks for the update, looks like the latest sane-find-scanner does
not think it is a currently-known Genesys chip.
Since the scanner is old, it could be an older Genesys or similar
chip, or else something entirely different and unknown (see below).

Perhaps you could do a UsbSnoop scan under Windows XP (virtual one
under Windows 7 probably will work too) of the smallest area you can
possibly mark with the windows driver (probably something like 4mm by
4mm or so). Zip that up and send it directly to me by mail to have a
look at (the mailing list won't accept such large attachments).

UsbSnoop 1.8 for Windows XP:
http://benoit.papillault.free.fr/usbsnoop/
Notes on usage:
http://lindi.iki.fi/lindi/usb/usbsnoop.txt

*If and only if* you are using WinXP, you might want to try a modified
from of UsbSnoop also, as a test---developed from the above 1.8 and
renamed SniffUSB:

I look forward to hearing from you on this.

Hi, the logs from the 4200F seems similar to those from the 5600F, and
maybe this is something like the canon630u backend protocol using the
GL640, judging by the 8-byte command sequences often beginning with
either 0x40 or 0xc0. Or maybe something elseI am not familiar with
that protocol.

Dear all,

So far the 4200F has shown no sign of being a "pixma" device. I also
received logs for the 5600F which appear somewhat similar. Does anyone
know if this might be related to canon630u ?

In a related thread, it was pointed out that there was (at that time)
too little information to tell what chipset was used, but the genesys
developer wrote that sane-find-scanner should be able to tell
(apparently the result is negative at this stage, but that does not
mean it is not a Genesys chip):

Yeah- but I wrote the detection code for the later chips based on a

 Assembled Wisdom!

 Almost a year ago, I bought a Canon ImageCLASS MF4770n, an

 it resides about six feet from my computer, and is connected

Hello Alan,


 I spent a little time this spring trying to get the scan
 function to work, but was not successful.  I am now
 returning to this issue, and I need help.

 First:  I have run sane-find-scanner, and it returns the
 line:
found USB scanner (vendor=0x04a9, product=0x2774) at libusb:001:004
 But when I run xsane as 'myself'(alan), also as 'root', I am
 told after a search, where my various USB lights blink, that
 there is 'no device available.'


What version of SANE do you have installed? You can look at the package
libsane, e.g.
aptitude show libsane
(on my Debian unstable installation it is 1.0.24-13, although I also
install the latest development version in /usr/local)

I believe that there is a backend for the MF4770.  However, I
 don't seem to have libusb, although my USB works fine for
 backups onto USB sticks, and, as mentioned, my USB connection
 to the Canon printer works fine.


pixma_imageclass.c:#define MF4700_PID 0x2774

The MF4700 series has been in SANE since before December 2013, so unless
you are using an ancient version of SANE, it is most likely that you have
the backend you need in SANE.

The documentation in README.linux that comes with the SANE code should help
you check the installation and do some debugging, or at least specify to
the list which steps you managed to succeed in, and where things failed.
On Debian systems, the files you can consult are in (read them with
zless):
/usr/share/doc/libsane/README.linux.gz (the above file, takes you through
custom installation, and section 4 has info to check setup)
/usr/share/doc/libsane/README.Debian.gz (a Debian-specific file with a
trouble-shooting section)

 Xsane offers 75, 150, 300, 600, 1200 and 2400 ppi.

 Canon's scangear however offers 75, 100, 150, 200, 300, 400, 600 and 1200
 ppi.


Hello Martin,
There is infact no such physical resolution as 200 and 400.
All the physical scans use resolutions which are multiples of 75.
A 200dpi scan will be done at 300dpi and scangear simply filters it down to
200.
Likewise, 400 is done at 600dpi and filtered down.
SANE implements the physical scanning capability. Since the 200 and 400 are
done in software, it would be a filter in the front-end, not the backend.
At least, that is my understanding.
Regards,
Gernot Hassenpflug

No idea why this is a new thread, but yes, your model needs to be

 Hello
 First, sorry for my bad english, but I will try it anyway.


Hello,
I found your message in my spam folder, not sure if it was because of
formatting (HTML?) or because of non-English words somewhere, but probably
this happens a lot, please be patient


 I send you this mail because I need some help. Maybe would you explain me
 how to proceed.


Unfortunately, I am not familiar with the installation on MacOSX using the
packages (although I know of the packages).


 I would like to run a HP scanner Scanjet 5300c » on a iMac os x 10.10 ,
 so as this one doesn’t see it, I searched for a solution. Founding SANE
 project, I downloaded Mattias Ellert's binary installer packages
 http://www.ellert.se/twain-sane/ of sane-backends, the TWAIN SANE
 interface and related software.
 Now this software appears on the computer, in the section printer and
 scanner. However when it is activated, the application does not found my
 scan. Awaiting the scanner  it’s said.
 Then, once the driver libraries opened I saw there was not Scanjet 5300C
 driver in it, although it is indicated on the page of SANE site to the
 section « Supported device », as you can see below? that it is in fact.


The driver is the avision backend, and that supports the scanjet 5300C.
You won't find a driver called ScanJet 5300C. The avision backend, if
compiled, will be used by SANE at startup to search for attached devices
matching the supported USB IDs registered (programmed into) that backend.
So if the avision backend is in the 1.0.24 SANE package, and this avision
backend supports the ScanJet 5300C, then running the frontend (whatever
application you use that uses SANE to do the scanning) should result in
your scanner being detected.
If not, then conceivably either the frontend is not using the installed
SANE yet, or the avision backend included does not support the ScanJet
5300C, or there is a permission problem somewhere that prevents the scanner
from being used.

sane-find-scanner merely uses libusb to detect the scanner, this does
not use the actual backend.
If you read the linux README that comes with SANE, you'll get the
details of how to compile from source (the CVS version) and test.
But for now, just use scanimage to scan, or use xsane if you want a

use the sane-pixma 0.17.4 backend that comes with 1.0.24).

  Yes, Sane can be the base for button-based scanning,
 but you will also need scanbd. Sane provides the interface
 to the scanner, scanbd will handle the logic. Scanbd cab be
 found here:

 First things first:

 A precondition is that SANE supports the device.

 But according to

 http://www.sane-project.org/cgi-bin/driver.pl?manu=canon;
 model=mxbus=anyv=p=

 it seems no Canon MX925 is listed at SANE which indicates
 that SANE does not support it.


Short one:
MX920 has been supported since December 2012 (see git Changelog), whether
ADF is perfect or not I am not certain.
MX925 is just a regional variation on the MX920 (proof would be to see if
the USB ID is the same).

 That's correct. At least sane-find-scanner says: chip=GL842.
 Do you have a physical access to the device?

Yes, I have one. I have some code also, tried to set up registers

[sane-devel] Problems with Canon MX715

2013-05-11 Thread Gernot Hassenpflug

Hello,
This device is part of the Canon MX710 family. I think the first thing to
confirm is whether the pixma driver works or not. That means, if I read
your debug output correctly, that you would be better off using USB
connection, rather than an ethernet connection. It is possible that the
ethernet driver layer has a problem, even if the pixma backend works
perfectly well.

Can you try with USB connection? (maybe that will also show up any
permissions problems)

 says 600x1200dpi so I wrote 600 in the backend.

Yes, I think that is correct for SANE (optical resolution).

 Hello,

 Allways when I open xsane and hit scan, I lose my network connection and the
 scan doesn't work.

Hello,
If you installed the Canon driver, you can't use Xsane to access,
since the SANE driver is completely different program from the Canon
scanner program. To use the Canon scanner driver you need to start the
Canon program for scanning.

Anyhow, for SANE, the the MP490 is supported but it depends on your
version of SANE. Also, I am not sure if it has been confirmed to work.
I suspect you may have permission problems, or else the argument you
need to give scanimage must be different. Can you try as root? And
also running xsane as root?

 Hi Erik,

 I guess that you don't have the user rights to access your scanner.

Erik,

would you be so kind as you give a clear description of the problem
you faced, and how you finally solved it (I think there may be a more
elegant method, like maybe something with symlink changes).
From what you wrote to me, it was a problem with the packaging of
xsane and installation using a high-level package manager like
synaptic.

Best regards,
Gernot

 Please try 'sudo scanimage -L'. If this is working, you need to copy
 'tools/udev/libsane.rules' from your sane's project folder to
 '/etc/udev/rules.d/' and join the group 'scanner'. Ubuntu uses udev to
 recognise the attached devices, please ignore the stuff around
 '/dev/scanner'.

 If this won't work, please reinstall sane from source as described in
 'README.linux' after Installation. You can ignore the stuff above
 Installation.

 Normally sane installation from source doesn't affect system's sane
 installation and vice versa, instead of some symbolic links, for your 32
 bits ubuntu in '/usr/lib/'.

 If any package installation or update might overwrite the symbolic
 links, you only need to create new ones as described in README.linux.

 Cheers,
 Rolf

 Secondly, I had Sane working brilliantly under ubuntu 10.04 with the

 now, after doing a completely fresh install of 12.04 i really cannot get

 here are some proofs.

 No scanners were identified. If you were expecting something different,
 check that the scanner is plugged in, turned on and detected by the
 sane-find-scanner tool (if appropriate). Please read the documentation
 which came with this software (README, FAQ, manpages).


 Advices from http://www.sane-project.org/README.linux:

 include /etc/ld.so.conf.d/*.conf

 locate libsane.so.1 after sudo updatedb
 /usr/lib/libsane.so.1

 Yesterday, I had for one moment the scanner working, then I installed
 Xsane through the command line, which give me a lot options of which I
 didnot know which one to choose. Since then, no success at all. Anyway,
 now installing xsane will mean it will downgrade to 1.0.22.

 If, one day, I will have SANE running, is there a way to install XSane
 without downgrading?


 and a last question, quoting from the README.linux

 It may help to set a symbolic link /dev/scanner to the respective device if
 automatic detection does not work.

 how do I do that?

 Thanks in advance.

 Hi,

Hello Madis,

Correct place, and excellent news, thank you very much fro testing!

 I own a Canon MG 3150 printer-scanner-copy machine. I saw that MG 3100
 series is untested (PIXMA MG3100 Series, USB 0x04a9/0x1752, untested,
 Testers needed!). I installed sane and xsane and was able to scan.
 Specifically I did a colour scan with 150 ppi resolution and a gray scan
 with 75 ppi. Both worked. Laptop and MG3150 talk over wifi (Archlinux,
 Thinkpad T410s).

Great. So there is no trouble with the basic command sending.

 If neccesary I can provide other relevant information or do more extensive
 testing.

Could you test scans up to the maximum resolution of the device, in
both greyscale and color please.
It may be that the maximum resolution does not work, and some filter
changes need to be made in the code for that.

I'll assume from the above that you have the SANE packages installed correctly.

 The pixma libraries were downloaded from the Canon Europe site since the 
 Canon USA site didn't have Linux files for the MX712 (I
 downloaded the files for the MX715 (cnijfilter-source-3.70) and had to do a 
 fair amount of changing of source code to get them to
 compile on the latest Fedorashould I post the diff's for the changes for 
 that here do you think?).

This is totally  unrelated.
Either you are going to use SANE, or you are going to use the Canon
driver for scanning, you have to decide.

 As for debugging via USB, I'm not sure now to go about doing that.  I can 
 easily tcpdump and windump from my Linux and Windows boxes
 and compare the conversations that go on between the scanner and the two 
 machines, I can strace gimp while I'm trying this or strace
 the scanning pid and see what it's getting (not sure how to do that on 
 Windows) but debugging via USB I'm not sure how to do exactly.

For a start, decide if you want to use the Canon driver or SANE driver.
If you want to use the Canon driver, you'll have to go somewhere else
for support.
If you decide to use SANE, then get rid of the Canon driver, read
man-pixma to understand how to set debugging, and then with the device
attached via USB use the command line sane-find-scanner with debug set
to whatever level is reqired to see if the pixma backend sees the
scanner.
Once it is established whether or not the pixma backend from the SANE
packages you have currently installed actualy detects the scanner,
then it will be possible to start debugging the functionality.

 I have installed SANE from git and I think I have the latest
 development version (1.0.24). The scanimage command gives

 $ scanimage -V
 scanimage (sane-backends) 1.0.24git; backend version 1.0.24

OK, that is fine. Then for sure it needs development.

 I have inserted a few debug printfs in the backend (e.g.
 pixma_imageclass and pixma_common) to trace the problem. Basically, it
 seems to run the initialization step,
 - query status (OK)
 - activate (0)
 - activate (4) -- I don't know what the arguments mean
 and those steps complete successfully (status is OK). The next command
 issues appears to be start_session which results in busy returned
 status.

Maybe the command block sent during a scan command needs some bytes
set differently.

 Unfortunately, I do not have access to a WinXP computer (or the
 scanner, actually -- it is located at my parents' house). If the only
 option here is a USB trace, then it will have to wait a while...

Yes, that would be best. The program to use would be SniffUSB v2.0.
For x86 and x86-64 architectures, and complete instructions for use:
http://www.pcausa.com/Utilities/UsbSnoop/default.htm

A generic look at the development of the sniffer program, for interest:

Note: you can use v1.8 as well, although the buttons are a bit
different, but please do not use Snoppy Pro or any other newer
derivative. Not only are they more confusing to use, but the log
format cannot be parsed by our current tools, making it much more

Could you ensure that the pixma driver backend works properly for all

If the backend is shown to work properly (some resolutions might need
to be programmed specifically for this device), then after that it

Could you read man sane-pixma and use the debug variable to get more

[sane-devel] parallel port sniffing?

 So I am wondering about the other question I asked: how would one
 sniff parallel port devices? I've never done that before.

Hello Stef,

 ? ?long go, I wrote a custom VxD that sets debug interrupts on parallel port
 addresses and then
 logs I/O in for of ASM opcodes. It works only in win 95 or win98. I can send
 it if you want.

Thank you for your reply---that sounds interesting. It is the first
reply I had, which I find a bit strange: does most development for
paralletl scanners rely on them working with a parallel-to-USB
connector (and then using UsbSnoop)?
I'll try that initially too, but I am afraid that the ALPS scan
software may not work at all, hence my looking at direct parallel
options.
At the moment I lack a Win95 or Win98 VM to try this on, but I'll keep
your kind offer in mind.

Many thanks once again,

 The epson, epson2 and epkowa backends all support the ESC/I protocol.
 The ESC/P protocol that I'm somewhat familiar with is for *printers*
 (and printers only, AFAIK).

 In your original mail you mentioned ESC S and ESC s commands. ?In the
 ESC/I protocol those commands are for get-command-parameters and
 set-auto-area-segmentation, respectively. ?This doesn't jive with what
 you described so I doubt those backends will be of any use.

 Do your logs include ESC f, ESC G and/or FS F, FS G (status and start
 scan commands)? ?If not, then these backends definitely aren't what
 you're looking for.

Hi Olaf,
No, there are no other commands apart from various ESC S, and then ESC
s for data reading.
It appears very simple compared to, say, the pixma protocol. Once I
have a few more log files I will write out the protocol here, so far I
have only clearly identified the resolution command, and data reading,
and what are presumable ready/OK pairs.
So maybe Canon just created some pre-pixma command format
I can rip out all the complicated stuff in the pixma backend and try
to make a new backend to support this. I figured though it might be
easier to rip out things or replace commands in a backend that uses
ESC/P style commands already.

[sane-devel] Two questions: ESC/P control set, and drum scanners

2012-06-10 Thread Gernot Hassenpflug

Hi all,

I've got 2 questions:

1) About scanners using ESC/P command set

I've just received some UsbSnoop data for a Canon MP130 multi-funtion machine.
Unlike the usual pixma command set, this seems to use an extremely
simple and abbreviated set of commands that looks like ESC/P.
The pre-data and post-data interaction uses an ESC S (capital letter)
for write and read, and the data reading uses ESC s (small letter).
I'm wondering if there is a backend already that uses a protocol based
on ESC/P command set?

2) about drum-scanners

I have a couple of ALPS drum-scanner printer/scanner combos (MD-4000
and MD-1500) which function through either a SCSI connection (for
Macs) or a parallel connection (for PCs). I haven't yet installed the
native scan software for Windows so I don't have any data yet, but I
wonder which backend might be best to look at for support. I don't
know if I should be expecting SCSI-over-parallel or something
complicated, and am unsure at this stage how easy it will be to snoop
the parallel connection.
What is a recommended way to do that? I am thinking that maybe I can
install Windows2000 (not sure if the scan software can run on XP) in a
VM, and then install the parallel driver via a USB converter cable
(the printers function well like that). If that works, I can use
UsbSnoop. But if not, I'll have to find a way to snoop the parallel
port maybe? For that would I need portmon, or is there some other
recommended software?

Gernot Hassenpflug

 Hi Ernest,

Hi Earnest,
The way to provide support in SANE for Canon drivers is to check the
protocol with USB sniff from Windows first, and then to add the
relevant support to the pixma backend.

Can you provide USB sniff logs and send them to me? A search of the
mailing list will show which USB sniff program (I have to check), and
then you need to scan at low-resolution first, a really really small
area.

 Hi Gernot,

 I don't have access to a Windows system at the moment, but I'll
 install the proprietary drivers for Linux over the weekend and take
 some captures. Is pcap format ok?

Hi Daniel,
Thanks for the response, that sounds excellent.
Hmm, I have no idea if pcap format is OK, I don't think there are any
tools in SANE to handle it, but I am sure I can dig up something.
In any case, if the differences are small I can just search for the
patterns I am expecting to find, and thereafter we can test with a
partially-working SANE.
Can you also check the USB ID of the scanner (vendor id and product
id) for confirmation (otherwise I can get it from the Windows driver
files myself).

Hi Daniel,

 Wireshark can be used to view the files, if that helps.

OK. Should be fine.

Usually I use a perl script created by the SANE developers, which can
give the plain output of the commands, and there are some associated
programs that can then build an image from the sniffed data. But
here luckily the issue is not that the protocol is completely unknown,
simply that some modes are not yet supported.

 Can you also check the USB ID of the scanner (vendor id and product
 id) for confirmation (otherwise I can get it from the Windows driver
 files myself).

 The ID in the desc file is correct (04a9:1746). This device is mostly
 working with the latest git version, but the highest resolution that
 works is 600 dpi, and the first scan after power-on usually fails
 because SANE doesn't wait for the warm-up (I think).

I see, that is easier then. But we have to check---could be a command
block bit is incorrect also.
I would still appreciate if you can send me the sniffs for the
lower-resolution working modes (in color, grayscale and B/W), that way
I can make sure the working modes match what is implemented, and then
check for differences in the 600dpi modes.

Best regards

 Are you sure with 600 dpi?
 The definition in pixma_mp150.c says 1200 dpi.

 Hrmm, apparently that's not quite right. I assumed 600 dpi was the
 maximum because everything up to and including that is working (with
 the other patch applied).

 The specs for this scanner claim 1200x2400, but I haven't been able to
 get that working so far. Scanning fails with an IO error on 1200 dpi,
 which I haven't looked into further.

[sane-devel] Support for CanoScan 9000F and others: splitting pixma_mp150.c into two drivers

2011-12-19 Thread Gernot Hassenpflug

More updates:

Compiled latest SANE from git successfully and tested MP810 as example
device. Worked fine at 4800 dpi in TPU mode.

I am attaching the diffs (diff -u current git file modified file
) for all the files that were modified to create and support the new
sub-driver, which I call pixma_mp810.c after the lowest-named device
it supports.

The attached file is a RARed file which expands into a sub-directory
named sub-driver-pixma_mp810.
It an be un-compressed using:

unrar x pixma_mp810.rar

The new or modified files are (all in /backend sub-directory):

Makefile.am
pixma_rename.h
pixma_common.c
pixma.h
pixma.c
pixma_mp150.c
pixma_mp810.c

Done.

2) Then I need to use the latest SANE code again to confirm that the changes

Done. Diffs are attached.

Testing process:

1) place new and modified files into /backend directory
pixma_rename.h
pixma_common.c
pixma.h
pixma.c
pixma_mp150.c
pixma_mp810.c

2) edit backend/Makefile.am to add pixma_mp810.c

3) autoconf automake
This sets up backend/Makefile.am to contain references to the new
pixma_mp810 sub-driver

4) BACKENDS=pixma epson2 ./configure
(I did not wish to compile with all backends, just the 2 I use).
This sets up backend/Makefile to contain references to the new
pixma_mp810 sub-driver

5) make
This does the compilation

6) edit backend/Makefile to remove the -g $(LOCKPATH_GROUP) from the
install-lockpath command, which for some reason is not understood by
my 32-bit Debian system and therefore breaks make install:

install-lockpath:
# $(mkinstalldirs) -m 775 -g $(LOCKPATH_GROUP) $(DESTDIR)$(locksanedir)
$(mkinstalldirs) -m 775 $(DESTDIR)$(locksanedir)

7) make install
This installs the new libsane libraries in /usr/local/lib/

8) modify xsane to test the new libsane
Note: for Debian, ldd `which xsane` shows that libsane is linked from
an entry in /usr/lib/i386-linux-gnu/:
libsane.so.1 = /usr/lib/i386-linux-gnu/libsane.so.1 (0xb76bf000)

So create links to the new libsane:
cd /usr/lib/i386-linux-gnu
ln -s /usr/local/lib/libsane.so.1.0.23 .
ln -sf libsane.so.1.0.23 libsane.so.1

Now xsane will see libsane.so.1.0.23 when it uses the link libsane.so.1

9) run xsane from command line and test scanner operation
First, set debug mode to see what is going on (3 is fine, 4 would
include some specific pixma debug statements):
export SANE_DEBUG_PIXMA=4
xsane

Done!

3) Lastly I need to update documentation.

Still to do.

That's interesting---same thing happens with me when I compile the CVS

The older system version works fine though.

In more detail: the preview window works in the sense that you can
do actions on it like selecting an area, just there is no display (it

is guesswork.

 I don't see an explicit reason given (such as permissions missing).
 Searching for comments regarding the actual error line yields no

 Any pointers much appreciated.

[sane-devel] Support for CanoScan 9000F and others: splitting pixma_mp150.c into two drivers

 Dear all,

 I've gotten down to the work of splitting pixma_mp150.c into two sub-drivers.

Status update:

I've split the driver very basically for now.

The new driver is called pixma_mp810.c, since that is the lowest
numbered MP device I added full (4800 dpi) support for there.

I've removed all other devices from it, save for those listed below
(MP810, MP960,970,980,990, and the Canoson 8800F and 9000F).

Added pixma_mp810.c to the following files:
1) backend/Makefile.am
2) backend/pixma_common.h
3) backend/pixma_rename.h

I haven't yet looked at adding/updating any documentation files.

Compilation works, so I will clean up the code a little, and prepare a
diff of the pixma_mp150.c over the next couple of days, since there
may be a few other changes I had made to existing supported devices
that could be not committed in git repository yet. If so I will submit
those diffs separately later.

Comments welcome.

Regards,
Gernot Hassenpflug

 The major new work in my customized pixma_mp150.c file is:

 1) support for 4800dpi scanning for existing supported printers
 (MP810, MP960, MP970, MP990 --- MP980 not explicitly supported yet)
 2) support for the Canoscan 9000F
 3) new interleaving of sub-images for the above.

 I propose that the following devices, which all have 4800dpi CCD
 capability, be removed from the original sub-driver and supported
 (fully) but the new sub-driver:

 1) MP810
 2) MP960
 3) MP970
 4) MP980 (no specific work done, assumed similar to MP970 or MP990 and
 to be added whenever testing can be carried out)
 5) MP990
 6) Canoscan 8800F
 7) Canoscan 9000F

 There are several CIS devices with 4800dpi capability, but these work
 fine with the existing sub-driver functionality.

 Furthermore, there are new devices from 2010 which I have added
 experimentally to my sub-driver which I have been distributing on an
 individual basis. The results are not known at this stage, but I
 assume that the CIS devices will work perfectly well with the existing
 sub-driver. I now added the 2011 devices as well. Of these 2010 and
 2011 modes, only the top-range models use CCDs with 4800dpi, and these
 should be added to the new sub-driver:

 8) MG8100 series
 9) MG8200 series

 To avoid breaking existing devices I would like to comment them out in
 the existing pixma_mp150 sub-driver file, and similarly comment out in
 the new sub-driver any devices which should be supported by the
 existing sub-driver.

 Please let me know any comments, in case they will be helpful for me
 to get this task done as soon as possible.

 Dear List,

 What is the status of the rewritten pixma-backend-driver? Gernot
 Hassenpflug/shugyo has been quite active on the subject until 4 months ago
 or something. The driver is not yet in the GIt repository so it seems.
 Would love to give it a spin on my Debian Squeeze system, but it seems the
 Mr Hassenpflug has been a bit busy so I am looking for an alternative
 source for the code. Or is it bound to appear in Git soon? Any thoughts on
 the subject?


Status update:
I've been busy with some other drivers the last couple of months, and part
of that work was finally completed this weekend. So my plan is to start
splitting the mp150 sub-driver into two separate sub-drivers: the original
one as much untouched as possible, all the new code shifted to a new
sub-driver, and then devices that should be supported in the new sub-driver
removed from the old one. That was the brief I received from the maintainer
but did not have time to do that work in the meantime.
You are of course welcome to the code anytime, I have been sending it to
anyone that requested it.

I will keep the list updated, and send the files I am working on, as I
start to work on the splitting operation this week.

Best regards,
Gernot Hassenpflug

 CanoScan 9000F is not in the list for supported devices in release 1.0.22,

[sane-devel] Canon MP250 detected by sane-find-scanner but not by scanimage

2011-07-23 Thread Gernot Hassenpflug

 I have a Canon MP250 device. The manpage of the pixma backend states that
 this device is supported, but when trying to use scanimage, there's no
 scanner detected.

 Test case:

 Plug the scanner, and check lsusb and /var/log/messages:

 # dmesg

- sane-find-scanner only checks libusb can detect the scanner, not if
SANE's backends are working or not. So all is well on that front at
least.

- check if pixma_mp150.c has this scanner listed in it. At the tip f
the file the USB ID, at the bottom of the file the properties.

- check if you compiled correctly (local compiles by default go into
/usr local so your scanimage should be running from there)

- run scanimage as root to see if it might be a permissions issue

HTH as a start,

 The latter moved one page through the ADF and the next was moved in a

 Which other tests can I do?


I suppose you could try with xsane (perhaps as root if permissions problems

 If you don't have the time, I can have a look at it, but I am currently

Hello,
I am not a maintainer for SANE. Also, I am not sure what code you are
using here. I have some code I have developed which I need to submit
eventually. If you send me your modification maybe I can do something

[sane-devel] dye-sub Canon ES20, ES40 help

Dear Michael Mraka,
This is Gernot Hassenpflug, I was told you are the person to speak to
about dye-sub printers. I hope that is OK.
I have been looking at the code in print-olympus.c and am a bit confused by:-

a) whether the ES20 support is correct, and
b) how to make changes to support the ES40

What I have done is looked at the first 20 or so bytes of printjobs
for both these printers. I did not loko further yet. So far, the first
20 bytes show some significant differences between the 2 printers, but
on the other hand, I cannot see there any specification of edgeless
or non-edgeless, or portrait vs landscape differences. Anyway,
here the comparison, mostly for the first 5 bytes (others are the same
except where noted), in hexadecimal notation.

Color:

postcard:
ES20: 40 00 01 00 02
ES40: 40 00 00 00 00

CP_L: (89mm by mm)
ES20: 40 00 02 00 02
ES40: 40 00 01 00 00

Card: (54mm by mm)
ES20: 20 00 03 00 02  and also 12th byte: 01
ES40: 40 00 02 00 00  and also 12th byte: 00

Black/white (postcard only):

ES20: same as color, but 8th byte: 01
ES40: same as color, but 4th byte: 01

Conclusions:

a) paper type numbering is 0-based for ES20, but 1-based for ES40
b) ES20 5th byte is always 02, while for ES40 it is always 00
c) for black/white, ES20 sets 8th byte to 01, while ES40 sets 4th byte to 01.

I am not sure of other differences yet, if there are any utilities
available to examine the print-jobs more easily please let me know.
Best regards,
Gernot Hassenpflug
