Canon pixma maxify mb2340, when turning on the machine immediately giving display support code 5040. can i have some hints about this error code?
Unfortunately, there is no solution to a 5040 error. Your printer will require service or replacement.
Temporary solution to fix error code:
Also, you can find here more canon printer error codes and their solutions.
The Canon will give this error when something is broken error 5040 means that the motor wires running to the ADF automatic document feeder are broken. The same error pops up on the Canon MB2140 maxify. I took the printer apart by removing the side covers then disconnecting the ADF ribbons and wires. then I removed the top back cover on the ADF where the wires go in and found the broken wires, soldered them together and covered with heat shrink. assembled and tested working. No more error
I hope this is helpful for all printer guys
