Initial power-up of the printer results in a 200.91B error.


Make sure all packaging material is removed from the Imaging Unit.

To do this:

  1. Open the front door.

  2. Remove the toner cartridge bottle.

  3. Remove the Imaging Unit.

  4. Remove any packaging material from Imaging Unit that may not have been removed, e.g., foam blanket, red shipping separator, and/or handtag.

  5. Reinsert all supplies and close the door.

  6. Power on the device and it should now be READY.



A covered input sensor triggers this error. It is most frequently observed when packing materials have not been fully removed and the printer is powered ON.
