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 4.3 Carriage servo. 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.
Code: 0955-0050
Description: Line sensor failure
Causes: Carriage PCA, Trailing Cable, 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 asks the customer to go to Support Menu by pressing the Power key continuously for 15 seconds.3. Go to Diagnostic Menu and run the Line Sensor diagnostic, see 4.7 Line Sensor (or ZIM, Spot sensor). 4. The call agent should arrange a service engineer visit to change the Line Sensor assembly; follow the onsite troubleshooting below. Line Sensor5. If a different system error is displayed then the call agent should perform the applicable troubleshooting procedure.Onsite troubleshooting and solution (service engineer)1. Go to Support Menu (see Entering the support menus) and run the Line Sensor diagnostic, see 4.7 Line Sensor (or ZIM, Spot sensor). 2. Remove the covers and check that the cable of the line sensor is connected to the Carriage PCA and it is not damaged. If the cable is not connected then reconnect it, and power on the printer again to check whether the error has disappeared.IMPORTANT:If the cable is damaged then replace the Line Sensor, see Carriage Line Sensor. Line Sensor3. Clean the Line Sensor and try again, see Clean the Carriage Line Sensor. 4. Replace the Carriage Assembly, see Carriage and Belt. Carriage assembly w/belt (36)5. Replace the Main PCA, see Main PCA Main PCA
