Drum rotation test check
NOTE: This test is especially important if refilled toner cartridges are in use.
The photosensitive drum, which is located in the toner cartridge, must rotate in order for the print
process to work. The photosensitive drum receives its drive from the main gear assembly. Use this
procedure to determine whether the drum is rotating.
1. Open the cartridge door.
2. Remove the toner cartridge.
3. Mark the cartridge drive gear with a felt-tipped marker. Note the position of the mark.
4. Install the toner cartridge, and then close the cartridge door. The start-up sequence should rotate
the drum enough to move the mark on the gear.
5. Open the product and inspect the mark on the cartridge drive gear.
Verify that the mark moved. If there was no movement, inspect the main gear assembly to make
sure that it connects with the toner-cartridge gears. If the drive gears function but the drum does
not move, replace the toner cartridge.
Component test (special-mode test)
This test activates individual parts independently to isolate problems.
Each component test can be performed once or repeatedly. If you turn on the Repeat option from the
drop-down menu, the test cycles the component on and off. This process continues for two minutes, and
then the test terminates.
