Ladies and Gentlemen,
This is just to report that after upgrading to
sane-backends-1.0.32-6.el8.x86_64
I have been able to scan with my new
Canon Pixma TS6420a which runs under TS6400
Since Pixma TS6400 is listed as not having been reported to work,
here is one instance that seems to work.
Can you confirm which resolutions you tried and if you tried Gray and Lineart
modes?
Also, could you confirm that the pixma backend was used? That would be part
of the device name, e.g. "pixma:...."
Here goes:
The device supports WiFi access, but I only use a local USB interface
This is what the Prieview window frame shows:
"Preview Canon PIXMA TS6400 Series:04A918D3_01D66D"
and the interpretation is: idVendor idProduct _ iSerial
This is what the xsane window shows:
Flatbed (just this option)
Color (Color, Gray, Lineart)
Full color range (only for Color and Gray, 10 different entries)
Resolutions (75, 150, 30, 600, 1200)
Of these I have scanned the following:
Color: Full color range only, all resolutions
Gray: Full color range only, all resolutions
Lineart: resolutions 150, 30, 600, 1200
resolution 75 reports operation canceled
I am no expert at this stuff, so it is hard for me to say if what
Lineart produces is what I should expect (the images look like the
preview though).
Hope this help, let me know if you would like more, AG
Thanks again for your report.
I have updated the description for this machine family along with your
report in functionality.
This issue in lineart I have seen similarly in an older machine, the
MX493. These machines do not support lineart directly bu are a
processing option in the pixma backend. It has some problems.
Cheers,
Ralph
