Cause: This is caused by a loose or missing screw that attaches the high
voltage power supply to the chassis in the area where the capacitor is mounted
to the chassis through the chassis lug. The missing screw prevented proper
grounding of the high voltage power supply to the LaserWriter II chassis.
Additional Information:
The printer was initially repaired for a lack of printout. The high voltage
power supply was found to be defective. When the high voltage power supply was
replaced the LaserWriter II started spilling toner badly during printing.
While the printer was properly diagnosed, during re-assembly a screw in the
high voltage power supply mounting was not re-installed. This caused a bad
ground connection for the high voltage power supply which caused excess toner
to be dumped from the cartridge.
