Fatal Error 121
My OKI C5800LDN printer displayed the Service 121 error last night. After reading the previous solutions, and trying them with no success, I followed the instructions in the service manual, and removed the High Voltage Power Supply Board. There are four cables that plug into the board, the rest of the electrical connections are made between spring loaded fingers that make contact directly with the board when snapped into place. I used a rubber eraser to carefully polish each one of the fingers and their connections points on the circuit board. I re-installed the board, and the error is gone.
C5800 printing vertical lines through pictures
The thin lines are caused by a worn out drum. Remove each drum in turn and look at the surface. It maybe hard to see the scratches and if so then send solid blocks of the primary colours one at a time and that will prove which drum is at fault.

A printer only prints what it gets from the pc/network. Therefore I would uninstall and reinstall the driver on your pc/server. Do not use the cd provided but download the driver from OKI's website.

Replace the fuser unit.
Before you replace the fuser, take it out and check for a piece of stuck label, paper, etc. You can spin the fuser roller by turning the gear on the side.
