Hi Serap,

If a fault condition occurs in the printer, the status indicator on the control panel flashes on and off, and the message display indicates the specific fault.

For the operator-correctable faults, After correcting the displayed fault, press the CLEAR key to clear the error message and status indicator and resume printing. If the fault message reappears, contact your authorized service representative.
If a fault is not correctable by the operator, you may 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 CLEAR key. If the message disappears, it was a false indication and no further attention is required. If the message reappears, call your authorized service representative at 1-800-243-3338.
