Ⅲ. Maintenance

Replacement of toner cartridge

  • Because these is not OPC protecting shutter, picture is affected by OPC light fatigue. Don’t open the right cover for a long time.

  • Although Toner Cartridges are equipped at each color space, caution message could be displayed by CRUM information.

  • When toner cartridge replace, PTB belt could be damaged.


Ⅲ. Maintenance

  • Using the handle, Completely open the access door.

  • Press the green release button on the inside of the access door to release the transfer belt.

  • Holding the handle on the transfer belt, lift the used transfer belt out of the printer.

  • Take a new transfer belt out of the package.

PTB Unit

Release Lever

  • Remove the paper covering the transfer belt by removing the tape.

  • Holding the handle on the new transfer belt, align in with the slots on the inside of the access door. Push down until it clicks into place.

  • Then lower the transfer belt until it is parallel with the access door and firmly seated.
