How to solve. Onsite troubleshooting and solution (service engineer)
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
on page 103 and perform 2.1 Carriage Servo, see 2.1 Carriage servo on page 106 to
check that the error has disappeared.
3. Replace the Encoder Strip, see
Encoder Strip on page 193 and run the Carriage Servo
diagnostics to see if the error has disappeared.
4. Replace the Carriage, see
Carriage and Belt on page 236.
