I have a Canon MFC642 have the drivers installed from the Canon website. Pages are printed off-center. I tested to make sure it wasn't a hardware issue by printing from different sources and they are all fine.

Also the scanner does not work. I imagine there are no supported Linux drivers.

Please how can I troubleshoot these issues?

Device URI: ipp://printer.local:631/ipp/print

I'm running:

4.15.0-118-generic
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 18.04.5 LTS
Release:    18.04
Codename:   bionic

EDIT: Output from airscan

$ scanimage -L
device `airscan:e0:Canon MF642C/643C/644C (a5:a7:ce)' is a eSCL Canon MF642C/643C/644C (a5:a7:ce) eSCL network scanner

$ airscan-discover

  • please add the settings used to print. could it be set to align left or have a larger printing border on one side. This might be an issue with default setting as it sometimes makes sense to leave some space for punching holes on the left. – totalynotanoob Oct 8 '20 at 23:50
  • All defaults. There are no settings for page offset – drum Oct 9 '20 at 1:18
  • What "sources" are you referring to in "printing from different sources and they are all fine"? When are they not fine? – xiota Oct 9 '20 at 4:16
  • I can give you a solution to the scanning issue but it is dependent on the device being connected by wireless. Is it? If not - could it be? – brian_p Oct 9 '20 at 11:00
  • @xiota By sources I meant printing from Android, Windows, USB. These all print fine. When printing from Xubuntu, it is messed up – drum Oct 9 '20 at 13:07

This is a solution for scanning over a wireless connection on Ubuntu 18.04. It also should work with wireless and USB connections on Ubuntu 20.04.

Download and install sane-airscan

The file needed is here

sane-airscan is part of Debian unstable and Ubuntu Groovy and regarded as a very competent driverless scanning utility for modern scanners.

I would appreciate knowing if you can now scan and having the outputs of scanimage -L and airscan-discover.

  • Oh wow. This did the trick for the scanner! Thanks a bunch. – drum Oct 9 '20 at 15:13
  • @drum Glad to have helped. The info I requested would be good to have because it will benefit other users. – brian_p Oct 9 '20 at 16:07

This a solution for printing that does not use the Canon drivers. Set up a print queue with

lpadmin -p PRINTER_NAME -v URI -E -m everywhere

PRINTER_NAME can be anything you choose but URI has to be ipp://printer.local:631/ipp/print.

I would test first with

lp -d PRINTER_NAME /etc/nsswitch.conf

and move on to a file that has previously printed off-center.

  • Why don't you combine your answers with separate sections for printing and scanning? – xiota Oct 11 '20 at 5:06
