Service Calls for the Copying and Scanning Functions
If an unrecoverable error occurs, the machine shows “E” and “0”, “1” or “2”
on the display alternately. When this happens, turn off the power switch, wait
a few seconds and then turn it on again and try again.
If you cannot clear the error and see the same service call indication after
turning on the machine, consult your dealer or our authorized service
representative. Report the error status and situation referring to the above
information.
