Repackaging of Printer after Testing

Installation of the “Paper Jam” Sheet and Separation of the Fuser RollsAn important step that should be done before the repackaging the printer is the separation of the fuserrollls. This will prevent flattening of the rolls, which can happen if the printer is stored for a long period oftime with them in contact with one another. In the factory, this is automatically at the end of theconfiguration process. In the field, this can be done by inducing a paper jam, which will cause the rollersto separate.

(1) Lower the jam access door, depress the reference edge, green release lever and insert a foldedsheet of paper into the paper path and under the reference edge rollers. Close jam access door.

(2) Power the printer on.

(3) Once the 200 Paper Jam message is posted on the printer’s display, turn the printer off. Leave the“Paper Jam” sheet in place and proceed with the repackaging.
