Hi, this is Michelle and i will be assisting you
please let me know if you are recieving any error codes on the printer
Please lift the document cover to open it
there will be small gray slide type switch on the top of the scanner, near the front left corner of the glass
slide the switch back and forth few times ensuring that the switch rests in the unlock position
once done turn off the unit and after a minute or so turn it back on
let me know the status
here is an image as well for you
Well the original error message on print request has reappeared. Error 5C10
Please help. I have switched off, then back on again and still the same.
please try the below steps
1.On the operator panel, press and hold the <ON/OFF> button for one second. (The display will go blank.)
2.Wait approximately ten seconds and then press the <ON/OFF> button again.
3.Wait until the device has completed its cycling process before submitting another job request.
also try the below
If even after performing the above steps the error repeats then the issue mighte be related to internal circuit board failure
if the unit is within warranty please contact canon to get the unit serviced.
however, in case its out of warranty, then my personal suggestion would be to take a repair quote from a local repair shop and based on the price decide whether you would like to go in for a new unit ans repairs for such service errors are costly and its better to opt in for a new unit.
let me know if you have any queries.
