  Cassandra RasmussenJul 27, 2025
  If your Oki Printer is experiencing a paper jam, several areas could be the cause. It could be around the duplex unit (press the button to display a remedy and remove the jammed paper accordingly), the front cover (open the front cover and remove any jammed paper), under an image drum or around the fuser unit (remove the print cartridge and gently pull out the jammed paper), or while feeding from a paper tray (gently remove the jammed paper by pulling the edge if visible). If paper jams occur frequently, clean the paper feed rollers.

  Diana ArellanoAug 21, 2025
  The 'EEPROM Reset' message on your Oki Printer indicates that the EEPROM on the controller is being reset. This can occur due to changes in CU ROM (when CU F/W version disagreement is detected), changes of destination channel, compulsive initialization of EEPROM (via the System maintenance menu), or an OEM set of PJL command.
