Meaning
During the drum maintenance cycle, when the drum
maintenance cam position should have been at blade
up/oil roller up, the drum maintenance cam home sensor
should have been FALSE and was instead TRUE. Check
the drum maintenance cam solenoid, clutch, home
sensor, and related hardware.
During the drum maintenance cycle, when the drum
maintenance cam position should have been at blade
up/oil roller down, the drum maintenance cam home
sensor should have been FALSE and was instead TRUE.
Check the drum maintenance cam solenoid, clutch, home
sensor, and related hardware.
At the end of a drum maintenance cycle, when the drum
maintenance cam position should have been at blade
down/oil roller down, the drum maintenance cam home
sensor should have been TRUE and was instead FALSE.
Check the drum maintenance cam solenoid, clutch, home
sensor, and related hardware.
During power-on initialization, the engine is unable to
disengage the process motor. Prior to declaring this fault,
the engine has attempted to move the process motor
through enough revolutions to disengage the head tilt
mechanism, but the motor stalled. The X-axis was then
displaced to the right 3.8 mm (0.15 in.) and the disengage
was repeated, but the motor stalled again. This fault is
then declared. The head is unable to move on its tilt axis,
perhaps because it is colliding with something (head
restraint pin, cap, poorly installed ink loader, screwdriver.)
Calibration Failure: Defined but not used.
The engine spent too much time in the printhead
adjust-state. The engine declares a device fault and shuts
down, rather than leave a hot heater against a cold drum
for an indefinite period.
The printhead format number, stored in printhead
NVRAM, is not understood by this version of engine
firmware.
Bad Message in main pc_ready message loop. The code
received an unexpected message while the printer was in
ready state waiting for a command from PostScript.
Typically this message is a PM_RESULT_OK message
that is the result of a previous command to PM to tilt the
head back. The odd behavior is that PC is not waiting for
the operation to finish.
