Carriage Test

Perform a Servo Cycle Test (10 cycles is sufficient) to verify carriage bushings are defective. Ensure Halt time does not exceed 90. Left to Right resistances are normally higher than Right to Left due to carriage heads pushing against ink delivery chain. Acceleration is also higher than Slew or Deceleration values.

Figure 4-74. Servo Cycle/PWM Menu.

If Halt Time is above 60 excessive drag exists on the carriage assemblies and the servo motor may be defective or the carriage bushings may be severely worn. At approximately 98, a ‘Carriage Axis Error’ will result. Push the carriage to the left end of printing area. Power the printer on, carriage head should return to station and size the media without error.
