Numerical printer messages
Note
Many of the procedures in this section instruct you to replace the DC controller PCB, the
ETB, the formatter, the drum drive motors, the drum drive gears, or a laser/scanner unit.
After replacing one of these items, you must access the Print Quality menu and select
CALIBRATE NOW to ensure proper print quality after the repair. See
Calibrate now, for
instructions on calibrating the printer. When the ETB or the fuser are replaced before their
normal end of life, access the Resets menu and reset the counter to zero. See
Replacing the
transfer unit (ETB) and Replacing the fuser for instructions.

that cartridge. Otherwise,
continue with step 3.
