Meaning
During the drum maintenance cycle, when the drum maintenance cam
position should have been at blade up/wick 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/wick 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 0.15 inches 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.)
The engine spent too much time in 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.
Ambient temperature has fallen to less than 10
wrong with a heater.
After the printer determined, at power up, that the printhead was warm
enough not to need cleaning, and while the printer was warming up the
printhead temperature dropped below the head-clean-needed threshold.
Something may be wrong with a heater.
Drum home sensor failure: the drum turned one full revolution without
seeing the drum home sensor activate. Check the drum home sensor.
The Y-axis (drum) motor stalled, possibly because the drum position
sensor electronics have failed, or because the motor drive or drive belts
have failed, or because something is physically blocking the motion of
the drum.
Y-axis position failure, the drum is not where is should be, possibly
because the drum position sensor electronics have failed, or because the
motor drive or drive belts have failed, or because something is physically
blocking the motion of the drum
The drum stalled: the drum stalled because the motor drive or drive
belts have failed, or because something is physically blocking the motion
of the drum.
Y axis position failure: the drum is not where it should be. Besides the
possible mechanical problems, this can be caused by software latency
errors, if too many interrupts occur during drum positioning.
