If the mark did not move, inspect the main drive assembly to make sure that it is meshing with the toner-
cartridge gears. If the drive gears appear functional and the drum does not move, replace the toner cartridge.
Half self-test functional check
The half self-test check determines which printing process is malfunctioning. This process requires you to
stop the product while it is in the process of printing a page.
1. Print a Configuration page.
a.
From the Home screen on the product control panel, touch the Setup Setup button.
b. Touch Reports.
c. Touch Configuration Report to begin printing the report.
2. Open the toner-cartridge-door after the paper advances halfway through the product (about five
seconds after the motor begins rotating). The leading edge of the paper should have advanced past the
toner cartridge.
3. Remove the toner cartridge.
4. Open the toner-cartridge drum shield to view the drum surface. If a dark and distinct toner image is
present on the drum surface, assume that the first two functions of the electrophotographic process
are functioning (image formation and development). Troubleshoot the failure as a transfer or fusing
problem.
If there is no image on the photosensitive drum, perform these checks:
1. Make sure you removed the entire length of the sealing tape from the toner cartridge before you
installed the cartridge.
2. Perform a drum rotation functional check to make sure that the drum is rotating.
3. Make sure that the high-voltage contacts are clean and not damaged.
