Fault Messages
IMPORTANT
Test the printer after every corrective action. Stop maintenance when
the symptom disappears. Always press the ENABLE/HOLD switch after
correcting a fault indicated by a fault message.
If the fault message appears after pressing ENABLE/HOLD, go to the
following tables, find the message, and perform the checks and corrective
actions listed in the table.
