Customer Question

Canon MG6120 error 6A81 (Jam?) occurred directly after I replaced some ink cartridges. The carriage will move left and right, appears to be blocked from parking in right hand side by a white lever toward the rear of the parking area, sort of an upward pointing hook. Hook will move down easily when pushed, does not appear to lock in the down position to allow the carriage to park.
JA: Has your Canon done this before? And can you guesstimate how old it is?
Customer: The printer was a NOS in kind replacement for the same unit which the printer head could not be unclogged, so only a few months old. No problems with this unit up until now.
JA: What troubleshooting have you tried?
Customer: Tried turning off, then on, same breakdown with parking. The unit goes immediately to the error message. I have looked in all the nooks and crannies for a paper jam, I don't think there's anything in there (the paper had not fed from the unit at the time of the error, and previously was working fine. All various and sundry pieces I had put in with the new ink are accounted for. I currently have the ink and head removed from the machine to improve visibility, there appears to be nothing odd with the head or cartridges. Just that white hook sticking out in the parking area.
JA: The printer expert can solve this for you. Anything else you want him to know before I connect you two?
Customer: Please review charges first.

Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.

Sorry to hear you’re having trouble.

This message indicates a carriage fault. That can be caused by anything from debris/obstruction (paper jam, bent/damaged rails, out of place purge assembly/wiper, or dirty/dislocated encoder strip) to an actual hardware defect (bad sensor or control board, faulty carriage drive motor/gear/belt, bad printhead/carriage pcb).

What we can try here are some cleaning and reset steps.
First, open up the printer, and check for any internal debris such as scraps of paper, paperclip or staple, etc. Check if you’re able to move the carriage manually, or if it moves on its own when lifting the lid. If it does move, you can proceed with cleaning by blowing out the inside compartment with compressed air and checking carefully on both sides for any obstructions. Then wipe down the encoder strip, which is a clear plastic strip running the width of the printer, that sits just slightly above and behind the carriage.

Then reset the machine:
unplug power at the wall outlet
wait 5 minutes
press and hold the power/on button for 60+ seconds
keep holding while plugging back in, and for another 60 seconds after, then release

Let me know the results, and I’ll advise further if needed.
