1. Remove covers and check that the Trailing cables are connected from the Main PCA or from the Carriage PCA. If any cable is disconnected then reconnect it, and power on the printer again to check whether the error message has disappeared. 2. Go to Support Menu, see Entering the Extended Support Menu for service engineers and perform 2.1 Carriage Servo, see 2.1 Carriage servo to check that the error has disappeared. 3. Replace the Encoder Strip, see Encoder Strip and run the Carriage Servo diagnostics to see if the error has disappeared. 4. Replace the Carriage, see Carriage and Belt. • Carriage assembly w/belt (24) • CQ890-67002 • Carriage assembly w/belt (36) • CQ893-67011 5.
