Code: 81:YZ
Description: Problem with paper advance.
Remedy: • Open the Window and check for any visible obstacles restricting the movement of the Drive Roller. If there is a wrinkled mass of media inside the paper path, lift the Pinchwheels (using the Media Lever) and clear the obstruction. • Perform the Media Drive diagnostic test to troubleshoot the problem further 2. Paper Drive. • Check the connections on the Main PCA; the Media Advance Drive is connected to the connector labeled Paper Motor. • If the System Error continues, replace the Media Advance Drive Media Advance Drive.
