Possible cause Solution
1 The print cartridge is not installed correctly. Remove the print cartridge and then reinstall it. The
top cover should close completely when the print
cartridge is fully seated.
2 The print cartridge is defective. Replace the print cartridge.
3 The fuser roller is worn or dirty. Process a cleaning page. See Cleaning the fuser.
Several pages might be required the fuser is very
dirty. If the problem persists, replace the fuser. See
Fuser.
4 The static-eliminator teeth (just beyond the transfer
roller) are contaminated or defective.
Clean the static-eliminator teeth by using a small
brush or compressed air. Replace the assembly if it is
damaged.
5 Light is leaking into the MFP. Make sure that all of the covers are in place. Move
the MFP away from windows that face the outdoors.
