6C10 code on mp620, cannot get printer to do anything but show this code on the lcd and tell me to shut off and try to restart.

Double check that the error isn't 6C10. I also thought I had an 8C10 error also and that's how I found your unanswered question! But I couldn't find any other internet reference to 8C10 but I did find a YouTube fix for a 6C10 error message. So I got my reading glasses and looked again. Sure enough it was a 6C10 error! I followed the instructions for the 6C10 error fix (resetting Ink Absorber Reset) and my printer is now functioning. Bonus note: My printer is a MP620 and the reset was for a MP550. Same error number though! and also same solution. By now your printer has probably crossed that printer rainbow bridge... but hopefully someone else will need your help? With my reset, I am going to run my $$$ ink cartridges out instead of maintenancing the absorber and then toss mine as well!

I Tried everything,then I had the print head in the middle and turned the printer upside down and shook,out fell a little piece of foam from one of the ink cartridge,now works great.

uninstall the programe with revo uninstaller

The purge unit is blocked,you need to unzip the printer and try to unlock or clean,if the problem persist you need to replace the purge unit.

This seems to work with many Canon models and is worth an attempt on your printer.


1. Start with printer off
2. Press and hold resume Button (triangle in the circle) and click "Power" button. Green led should be on
3. While holding the Power button, release the Resume Button.
4. Without releasing the Power Button, click "Resume" button for two times and release Both Buttons.
5. Click "Resume" for four times then soon click "Power" button, to confirm the selected action (reset counter absorber).
6. Turn off the printer and turn on again

after youll be sure that you have communication with your internet modem ! delete your printer from your computer and install it again. at list thats what i did with my mp640 on my mac book. system preferences/print + fax. i suppose its something similar with the pc. i solve my problem this way. hope i help.

If you have used the printer over 6,500 copies then the ink pads below the cartridges will be full and need replacing all printers will stop and give a warning to this effect it can be reset using a secret menu if you have an LCD control panel use my Brother DCP-340CW solution
