Description: Feed encoder sensor does not work properly. Main PCA, Feed encoder Disk
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 encoder sensor PCA. • Feed Encoder Sensor PCA • CQ890-67020 3. If a 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 note: If any cable is damaged then order a Cable Service Kit. • Cables Sk • CQ890-67021 2. Replace the Feed Encoder Sensor PCA , see Encoder PCA and Index. • Feed Encoder Sensor PCA • CQ890-67020 3. Check that the Encoder Disk is not dirty or damaged. If the Encoder Disk is damaged it should be replaced, see Encoder Disk. • Encoder Disk • CQ890-67033
