Service Call Error Messages
A fatal error is any error that cannot be corrected by operator actions alone. The errors listed in the table
that follows are all potentially fatal errors. However, except for one error, you might be able to clear them
by resetting the printer engine. That one exception is the error “33 REPLACE EEPRM,” which is fatal and
cannot be cleared by resetting the printer engine.
NOTE: Before performing any corrective actions, reset the printer engine, as
described below. If a given error continues to appear on the LCD after you
reset the printer engine, then cycle the power to the printer. If the error
persists, it means that the printer requires further service.
Resetting the Printer Engine
To reset the printer engine, press the Up and Next keys on the control panel simultaneously.
