Description: NVM backup is missing or does not work correctly (NVM location).
Causes: Main PCA
Remedy: Remote troubleshooting (call agent) Restart the unit. If the problem persists, then: Onsite troubleshooting and solution (service engineer) 1. Remove left cover, and ensure NVM backup cable is properly connected to it and to the Main PCA. 2. Replace the NVM backup. 3. If the issue persists, replace the Main PCA.

Description: Feed index encoder sensor does not work properly
Causes: Feed Encoder Disk, Main PCA
Remedy: Remote troubleshooting (call agent) 1. Switch off the printer, and disconnect the power cord. Reconnect the power cord and power on the printer. 2. The call agent should arrange a service engineer visit to change the Feed Index PCA and follow onsite troubleshooting below. • Feed Index encoder sensor PCA 3. If a different different system error is displayed then the call agent should perform the applicable troubleshooting procedure. Onsite troubleshooting and solution (service engineer) 1. Remove the covers and check that all the cables are well connected to the Main PCA, and none of them are damaged. If any cable is not connected then reconnect it, and power on the printer again to check whether the system error has disappeared. IMPORTANT:If any cable is damaged then order a Cable Service Kit: • Cables Sk 2. Replace the Feed Index Encoder Sensor PCA, see Encoder PCA (CQ890-60204) and Index (CM751-60021) • Feed Index encoder sensor PCA 3. Check that the Encoder Disk is not dirty or damaged. If the Encoder Disk is damaged, it should be replaced, see Encoder Disk (CQ890-67033). • Encoder Disk

Description: Encoder Strip failure
Causes: Carriage (encoder sensor)
Remedy: Remote troubleshooting (call agent) 1. Switch off the printer, and disconnect the power cord. Reconnect the power cord and power on the printer. 2. The call agent should arrange a service engineer visit to change the Encoder Strip and follow onsite troubleshooting below. • Encoder Strip (36) 3. If a different different system error is displayed then the call agent should perform the applicable troubleshooting procedure. Onsite troubleshooting and solution (service engineer) 1. Remove the covers and check that Encoder Strip is not broken or dirty. • Cables Sk 2. If the Encoder Strip is dirty, follow the procedure in this manual to clean it, see Clean the Encoder Strip. 3. If the Encoder strip is damaged or does not work, it should be replaced, see Encoder Strip (CQ890-67096 & CQ893-67029). 4. If this fails to solve the issue, the problem might be due to the encoder sensor within the carriage. In that case, replace the carriage, see Carriage Assembly with Belt and Trailing Cable (5HB06-67001 & 5HB10-67001).

Description: Multi-Sheet Tray presence not detected
Causes: MPCA
Remedy: Remote troubleshooting (call agent) Ensure that the Multi-Sheet Tray is properly placed and the latch is closed. Onsite troubleshooting and solution (service engineer) Ensure that the Multi-Sheet Tray sensor cable is correclty connected to the MPCA, checking the J27 connector in the MPCA.

Description: Carriage homing problem
Causes:
Remedy: Remote troubleshooting (call agent) 1. Reboot the unit. If the problem persists, clean the encoder strip, see Clean the Encoder Strip. 2. If the issue is not solved, open the PHA door and check if there’s any paper strips blocking either the carriage or the SVS. 3. Go to Diagnostic Menu, see Entering the support menus and run Carriage Servo diagnostic, see Test Carriage. Onsite troubleshooting and solution (service engineer) 1. Check encoder strip, scan axis and service station parts. 2. Depending on the failing subsystem, any one of them may need replacing.
