Turn the Printer off. Manually move the carriage along the carriage axis.
Check for any areas where the carriage may be binding.
3
Ensure that the belt and belt pulley are in correct working order. Remove
dirt from the pulley that could cause the belt to slip.

Remove dirt from the slider rod and chassis beam. Apply oil (Anderol
4068, HP part number: 6040Ć0858) to the carriage bushings.
5
At high temperatures, and if the fan is not working correctly, the internal
resistance of the motor driver may increase, causing a decrease in the
voltage between the motor contacts, and a shutdown of the motor.
6
Ensure that the encoder strip is not inverted, damaged or absent.
