Repairing a laser printer requires technical skill and intimate knowledge of the xerographic printing process. It is not recommended for end users to perform complex repairs on laser printers.
If you wish to repair your Oki printer yourself, locate the correct part numbers for repairing your printer. Use the proper okidata parts diagram for your printer to find the Oki part numbers. For diagnostics and repair procedures, you can request a free service manual.
Many repair parts ship directly from the manufacturer so the availability is not know until you order. In the case of manufacturer backorders, the order is filled on a first order first served basis.
