58 Troubleshooting
a.
Recoverable unit check conditions are errors detected in the
electromechanical print mechanism that may be temporary and
correctable by cycling power. The printer tries a number of times to
correct the condition before posting the message to the operator
panel. The first thing to do in such cases is to power the printer off,
wait 15 seconds, then power the printer back on. If the message
reappears, classify the check condition unrecoverable.
b.
Unrecoverable unit check conditions are “hard” failures such as
overcurrent, component failure, or microcode failures that prevent
printing until the conditions are corrected. Unrecoverable conditions
require that the printer be powered off and the condition corrected
before powering the printer back on.
Clearing Error Messages
Refer to the Message List below, which lists the display messages
numerically and alphabetically and directs you to a troubleshooting
procedure.
After correcting an error, press the Stop key to clear the message and return
the printer to the NOT READY state. Press Start to resume printing.
(If an error is not cleared, the printer will try to print again but will display
another error message until the error is cleared.)
