30 Phaser 840 Color Printer
Meaning
Ambient temperature has fallen to less than 10
Something 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 hardware. The
head may need to be renormalized.
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.
Cannot tilt head forward. The engine was attempting to
do something that required the printhead to be in print
position. The printhead was not in position and some
condition was preventing the code from tilting it.
Drum-home sensor failure: the drum turned one full
revolution without seeing the drum home sensor activate.
Check the drum-home sensor or I/O board 1.
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.
X axis motor over/under current. Indicates motor coil(s)
are open, or shorted, or the motor fuse has opened.
