MP145 with E42 22 ?

SOURCE: I got E42 22 error code,it a scanner error,how do I fix it

code 42 error definitely caused by loose flat cable from the scanner down into the electronics. End of the cable does not have a plug, just solder on each element, push the cable into its socket.

Had exact same problem. Scanner light should come on at power up. Found ribbon cable connecting scanner unit to base had come unplugged from socket on circuit board. The ribbon cable is one of three found near back hinge of scanner and is hidden underneath the other two. It should drape over the edge of circuit board and then plug into small recepticle on inner side of board. I plugged it in and printer works again. Hope this helps.

Read the Manual (comes with Tool). If you don't have the Tool download it from the Canon site. Go to the copier and press the System/Options button next to Copy/Mailbox/Fax. Press Online. Then try scanning. Go back to copier and press Offline so can photocopy again.
