Simple scan multiple page issue - Unable to read frame from device - Canon mf244dw

[Christopher Hill]

Hello,

When scanning multiple pages from a Canon mf244dw via the LAN I only get the first page scanned, then an error message.

Running "simple-scan -d" and looking at the output I see the following:

    [+123.87s] DEBUG: scanner.vala:1321: sane_read (7651) -> (SANE_STATUS_CANCELLED, 0)
    [+123.87s] WARNING: scanner.vala:1337: Unable to read frame from device: Operation was cancelled
    [+123.87s] DEBUG: scanner.vala:768: sane_cancel ()
    [+123.87s] DEBUG: scanner.vala:771: sane_close ()

I do notice that the scanner is already feeding in the second page before the first page has completely rendered on screen - perhaps it's going too fast?

Thanks

Please provide full debug logs from simple-scanner

Attached as a file the full output for "simple-scan 3.34.1" when scanning 2 pages from the feeder, which still has this bug.

Final few lines are here:

I checked on Sane supported drivers, and your device is well supported (pixma backend):

http://www.sane-project.org/sane-backends.html#S-PIXMA

"i-SENSYS MF240 Series Flatbed and ADF scan. All resolutions supported (up to 600DPI, ADF up to 300DPI). 216mm image width buggy, restricted to 215mm."

Please install xsane and check if you could reproduce this issue.

Very similar failure observed - the 1st page scans, but the 2nd fails.

Errors in logs are different however:

It seems that the issue is connected with Sane backend (pixma).
Please check on bug list, if the issue was already reported:
https://gitlab.com/sane-project/backends/-/issues

You could also report the issue to mailing list:
https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/sane-devel
