      To resolve a FEED JAM or EXIT JAM on your Oki Printer, first remove the tray and clear any misfed sheets. Then, open the top cover and carefully lift out the image drum along with the toner cartridge. Remove any jammed sheets from the paper path. Re-install the image drum with the toner cartridge, and close the top cover securely. The printer will warm up and begin printing when ready. If the edge of the jammed paper protrudes, remove the jammed paper from the exit when the exit roller begins rotating after a few seconds after switching on.
