Can't remember, but if there is a cleaning pad assy, it may not be seated in home position, causing the short-if present, run the cleaner back-and-forth.

Didn't those machines have a recurring problem where a gear on the back of the machine would get stuck (when opening the machine) and wouldn't give movement to the drum unit, causing blank copies?

More tips:
DESCRIPTION: Blank copies.
PROBABLE CAUSES:
1. CN32 at the HV unit is disconnected. Reconnect CN32.
2. Currents cannot be adjusted. No output from the high voltage unit. Replace the HV unit
DESCRIPTION: Blank copies.
PROBABLE CAUSES:
1. IP2 on main control board open, preventing 24V DC from reaching HV unit.
2. Check the Transfer/Separation contact springs located at the rear of the T/S corona Unit. Expand the contacting springs to ensure sufficient upward pressure.
