[sane-devel] Back-end for CanoScan 3200F?
Quoting Lauri Pirttiaho lauri.pirtti...@luukku.com: Hello, =20 A while back there was some discussion about the back-end for CanoScan 3200F, a currently unsupported scanner. I would like to know if someone is actively working on this scanner. Also if anyone has definitive information about the on-board controller ASIC, I would be very thankful. Especially if someone has soldered open the EMI shield of the controller board, I would like to hear what is there beneath. The genesys backend gl841 MAY be the closest to what=20 you are describing here, but some details you mention show small variance from the gl841. The backend for the gl841 probably best described as an early start, or a stalled project. The project remains blocked due to access to the=20 registers, and unknown vendor read/write commands. From my tests on Canon LiDE 35 that scanner NAKs every attempt I have tried so far. =20 What I know so-far is that the suspected chip is some of the SQ chips and that there is on-board MCS51 micro controller (MCU), either built-in to the controller ASIC or as a separate chip. =20 From analyzing the USB traffic in Windows XP I have already deduced the working boot procedure, some scan head control commands and partial procedure to make a full plate scan. =20 The controlling procedure involves three types of=20 control commands. There are direct writes to/reads from the external memory space of the MCU, some high addresses of which seem to be memory mapped peripherals. These are the single byte vendor write and read requests 0x0c (read) and 0x04 (write) to wValue 0x00e1 (read) and 0x00e0 (write) with the address at wIndex. Providing details on what went down the usb bus would=20 certainly help. The log from a scan may provide some clues to what is currently unknown. It would also be helpful is someone with a Canon LiDE 35 could post a log so that more information would become available to that project. Then there are command with varying values and indices of varying length (some of which have easy to find uses (like write to value 0x0071 index 0 which=20 homes the scan head, read form value 0x0040 index 0 which returns some status information like whether the scan head is moving and if it is at home position, My read of the gl841 registers show that the home position sensor would be in register 0x0041 values 0x0023 and 0x0024 index 0 which move the Here the gl841 seems to show register 0x0022 and 0x0023 for this, probably. scan head forward and backward by given length etc.) Some are not so easy to deduce. Third type of command is upload of several blocks of data to the external memory space of the MCU (at address 0xdd00) which seem to contain various masking, ramping etc. data details of which is unknown to me but which directly affects e.g. whether the scan comes out as all black or something visible and also seems to affect the motor operation. The logs that would show data being written to the address of a MPU are of interest, as the gl841 still has some=20 unknown problems that stall that backend. =20 If anyone can deduce from the description above more about the on-board controller, I would like to hear. =20 I am in process of preparing a more detailed collection of my findings, but if there is already a project to make the back-end for this scanner, I would like to submit the findings to that common pool. I hope you will keep this list informed of your effort. The genesys gl646 portion of the genesys backend has been mentioned as ready, but the other gl841 is positively not ready to be included in the sane CVS. I think the gl646 could use more testing. The project can be accessed in the sane CVS, co experimental. =20 With best regards, =20 Lauri Pirttiaho Oulu Finland =20 Thanks for your news. Good luck with your efforts. Gerald=20 --=20

Hi I am owner of a Canon LiDE 35. I created a program which is able to scan a whole page at 600dpi, 8bit color using libusb. It does calibration of led-timings and shading. I tried to use the minimal set of registers. The order of gpio settings on initialization is important, the scanner locks up/resets if done wrong.

[sane-devel] Back-end for CanoScan 3200F?
hi! Two scans of the same image would be more helpful. What I am looking for is to identify the vendor commands that set register values. I have not been able to identify a vendor write or vendor read command yet. A greyscale 8-bit depth and a color at 16 bits would be excellent. i hope that i did everything right and snooped a scan of the same little image in grey and color mode .. i guess the reinitialisation of the scanner is also at the begining of every logfile .. i'm quite impressed that the logfiles are so huge once decompressed .. (14MB) pfff the image is about 1cm2 so there should be nothing special about. the snoopfiles (including the small image) are downloadable at http://iki.boku.ac.at/download/lide35 if i can do anything else just mail .. i'd really like to see this scanner working with linux (and i think there are several ppl else out there) ;) regards werner
[sane-devel] Batch Scanning.
The problem is, the backend gives an Invalid Option? message that prevents it from scanning when turning that feature on. I can send more verbose output if anyone is interested. Tyler. sorry tyler, i have not had a chance to even look at length detection. i have not a clue just what the scanner does when that is set. very little chance of it being simple :) what size are the finished documents after you scan? all of them 23 inches long? allan Precisely :-) I'm assuming that SANE just does a loop until it reaches the scan area's boundary then starts the next sheet? (Or is that a function of scanadf?) Anyway, it'd be interesting to get this somehow shoehorned into sane-fujitsu. actually, it is entirely the scanners fault, i quote from the beautifully translated interface manual for the 4097 If the length that is not within the physical length is specified, the data is padded with dummy data white for the number of bytest exceeding the physical length before it is transferred. so you asked for 23 inches, you get 23. from looking at the manual and the code (briefly), i think the backend gives the options for length detection, but does not actually implement the code needed to use it. can you give more debugging error info, so i can see how far it gets? allan Tyler. -- so don't tell us it can't be done, putting down what you don't know. money isn't our god, integrity will free our souls - Max Cavalera

[sane-devel] network scanning
Hi, I would like to setup a multi-function device (printer/scanner) to work off of the network. I'm looking at an Epson Stylus CX5400 because of some reviews and it appears to be well supported in linux (both the scanner and the printer). However, I am well open to suggestions. For inkjet, I'm looking at the $250 range, but I am also interested in color lasers under $500 if one could be found. I have a building with about 15 computers networked, and I'd like to share both the printing and scanning capabilities. 1. While most of the computers are (debian) linux 2.4.xx based, interlopers occasionally bring in their windows based laptops. I'm not too concerned if they can't scan, but it would be a nice thing if they had that option. 2. I'd like to avoid having to have a computer physically connected to the printer/scanner if at all possible. So, I'm looking for suggestions on how to accomplish this. Does anyone have experience doing this? Is there perhaps a printer/scanner out there that has built-in networking capabilities and is supported by linux? Is there a scanner server (like a network/usb print server) device that would allow me to do this? Thanks in advance for any help that can be given. -John --=20 YourTech, LLC - http://yourtech.us/ (this account is used for mailing lists)
[sane-devel] network scanning
Hi John, I have a Dell 1600n network printer/fax/copier/scanner running with Debian. Network printing is fine with a generic postscript driver. The printer is a monochrome laser. There are also colour ones in the series but I've never used one. When I bought it I didn't find any Linux network scanning support but I have written a perl script which works as a driver for JPEG (200dpi colour) and TIFF (monochrome) network scanning. See http://www.jon.demon.co.uk/dell1600n-net-scan. The current status of the driver is basic but working. I don't know how well the USB interface works under Linux as I don't have any computers that are new enough to support it regards, Jon == Jon Chambers = http://www.jon.demon.co.uk, 020 8575 7097, 07969 956575 = On Mon, 27 Jun 2005, John (yt) Hogenmiller wrote: Hi, I would like to setup a multi-function device (printer/scanner) to work off of the network.
