Fault Messages Requiring Field Service Attention
If a fault is not correctable by the operator, the fault message is followed by an
asterisk (*). This usually indicates that an authorized service representative is
needed. You should try two steps to clear the fault before calling your
authorized service representative:
1.
Set the printer power switch to O (off), wait 15 seconds, then turn the
printer on again. Run your print job again. If the message does not
appear, it was a false indication and no further attention is required.
2.
If the message reappears, press the (Pause) key. If the message goes
away, it was a false indication and no further attention is required. If the
message reappears, call your authorized service representative.
