• Code: 78.1:YZ
• Description: Media settings area missing in media settings file.
• Remedy: • Switch the Power OFF from the back of the Printer and disconnect the Power cord. Reconnect the power cord and power On the Printer. • Check that the Printer has the latest Firmware version. If not, update the Firmware to the latest version. • Update the OMES of the paper type that is failing.

• Code: 78:08
• Description: The job received can not be printed without borders on this paper.
• Remedy: • Use a paper that supports borderless printing. • This system error code does NOT require service help. It should be resolved by the customer.

• Code: 79.1:YZ
• Description: Recoverable firmware error that does not stop the printing process.
• Remedy: • Switch the Power OFF from the back of the Printer and disconnect the Power cord. Reconnect the power cord and power On the Printer. • Check that the Printer has the latest Firmware version. If not, update the Firmware to the latest version.

• Code: 79:YZ
• Description: Generic Firmware error.
• Remedy: • Switch the Power OFF from the back of the Printer and disconnect the Power cord. Reconnect the power cord and power On the Printer. • Check that the Printer has the latest Firmware version. If not, update the Firmware to the latest version.

• Code: 81:YZ
• Description: Problem with paper advance. This source of error could come from an error in any of the following systems: paper motor, disk encoder, cables or main electronics.
• Remedy: Initial checks: This error can occur because the printer has been dropped during transportation, causing structural damage. Before continuing with the 81:YZ troubleshooting, first look for structural damage. To identify the structural damage, look for the following three things: • Consistent 81:YZ error codes. • Platen fingers rubbing on the roller surface, leaving black marks on the roller. • A gap on the platen beam. If there’s any gap in Z (vertical direction) between the plastic feature of the platen and the metal side plate, then the chassis is damaged and the unit cannot be repaired.
  Corrective Action: • 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. • Check the connections on the Main PCA; the Media Advance Drive is connected to the connector labeled Paper Motor. • Adjust the encoder disc and motor mount configuration . See the installation instructions on. • If the System Error continues, replace the Media Advance Transmission.

• Code: 85:YZ
• Description: Problem finding the Drive Roller zero.
• Remedy: • Check that the Media Advance Drive is connected properly to the Main PCA and is not damaged. The cable is labeled “Paper Motor.” • Perform the Media Drive diagnostic test to troubleshoot the problem further. • If the System Error continues, replace the Encoder Disk and Encoder Sensor. • If the System Error continues, replace the Main PCA.

• Code: 86:01
• Description: Problem moving the carriage, most likely due to a paper jam.
• Remedy: • Switch the Power OFF from the back of the Printer and disconnect the Power cord. Reconnect the power cord and power On the Printer. • Open the Window and check for any visible obstacles restricting the movement of the carriage. If there is a wrinkled mass of media inside the paper path, lift the Pinch wheels (using the Media Lever) and clear the obstruction. • If there is no paper jam or obstacle blocking the carriage movement perform the following: – Clean the encoder strip. – Check the belt assembly. – All cables and connections between the Carriag PCA, Scan Axis Motor, and Main PCA. – Oil the carriage rails. • Perform the Scan Axis Diagnostic Test . Page 3-6. • If the diagnostic test does not find any specific error, replace the Carriage Assembly. • Replace the Belt Assembly. • Replace the Scan Axis Motor. • Replace the Main PCA.

• Code: 87:YZ
• Description: Problem finding the Scan-axis encoder reading.
• Remedy: • Upgrade the firmware. • Clean the Encoder Strip. • Replace the Encoder Strip. • Replace the Carriage PCA. • Replace the Trailing Cables.
