8.If the carriage assembly suddenly stops at left end of unit during initialization - initialization does not complete (dim or blank control panel display), this could be the symptom of a defective paper sensor. This could also be due to a faulty power supply. The paper sensor should sense the platen on the return trip but may fail to do so - no error code given. Replace paper sensor on the right carriage in this situation, unless the power supply is proven defective first.

9.Disconnect the servo motor and stepper motor connections at Main PWA. Check for proper voltages with the various loads isolated. Replace motor as necessary. Refer to Disassembly.
