Question about Kyocera FS-3900DN Laser Printer
Most probably the drum unit has shifted slightly out of position. Remove the toner/process unit, open the cover on the left side of the machine, Remove the waste toner bottle. You will see a grey release button for the drum unit, press it in, slide the drum unit out a couple of inches and slide it back in firmly so that it seats and clicks in completely. Reinstall removed parts. Should be good to go.
