Main Drive Service Check
Service Tip: Excessive gear or main drive assembly noise is usually
caused by a defective motor assembly or engine board.
Service Tip: If there are equally spaced horizontal lines across the
page, go to
“Print Quality - Evenly spaced horizontal lines or marks.” on
page 2-92
.
Warning: Whenever the gearbox assembly is removed from the
machine it must be handled very carefully. Do not allow any of the
gears to come in contact with any metal or other hard surface to
avoid gear damage. It is also very important not to let any dirt, paper,
staples or other material come intact with the grease in the gearbox
assembly.
FRU
Action
1
Main Drive Assembly
(Excessive noise or
vibration)
Remove the controller board and run
a Diagnostic Print Test in the
continuous mode. Check the main
drive assembly for any excessive
noise or vibration. Determine if the
noise is in the main drive, toner
cartridge, fuser or main drive
gearbox. Look for any loose or worn
parts in the developer drive
assembly, main drive gearbox or
fuser. Repair as necessary.
2
Main Drive Motor Assembly
(Excessive noise, gears
ratcheting and so on)
A service error code 936 - Transport
Motor may be displayed. Check the
voltage at J12-6 on the engine
board. It measures approximately
+5 V dc when the motor is not
running and goes to 0 V dc when the
motor is running. If incorrect, replace
the engine board. If this does not fix
the problem, replace the main drive
motor.
3
Main Drive Motor Cable
Check the continuity of the main
drive motor cable. If incorrect,
replace the cable.
