Definition
Calibration Failure: Defined but not used.
The engine spent over 20 minutes 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.
Remove the adjustment tools and cycle power.
The printhead format number, stored in printhead NVRAM, is not
understood by this version of engine firmware. Verify the correct
printhead is installed. Replace the printhead.
Bad Message in main pc_ready() loop. The main message loop
in pc_ready() received an unexpected message while the printer
was in ready state waiting for a command from PostScript.
Typically this message is an unexpected or out of order
RESULT_OK message that is the result of a previous command
to one of the server tasks to accomplish some action (like tilt the
head back). The odd behavior is that PC not waiting for the
operation to finish.
Ambient temperature has fallen to less than 10
may be 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.
Calibration Failure: Target Volt-Sec Area of Fast Color mode
could not be achieved. Check the printhead cabling. Replace the
printhead.
Declared when the printer is booted and the head/cap contact
flag is set in NVRAM. The printer cannot run with the head and
cap/wipe/purge unit in contact because it would be unwise to
separate the two when the printhead is cold.
Declared when the printer is booted and the drum is dirty.
Cleaning the drum when very cold could increase the chance of
gluing media to the drum surface and creating a mess around the
stripper fingers.
Dangerous Process Motor Motion Detected. The PC task is
about to send a command to the process motor to print, chase,
move the eccentric cam or move the dm cam, while the PC task
detects that the printer is in a dangerous position from such a
move (damage could result).
Head Cal Task Spawn Failed. An attempt to spawn the head
calibrate task failed. This may be due to a low memory condition.
