A symptom of failure includes when media is loaded and the printer
rejects the media and spits it out the rear of the printer. First ensure the
entire platen surface has been thoroughly cleaned using distilled water on
a lint-free cloth. One quick solution for this problem is to loosen the two
securing screws and change the pitch or angle of the sensor to the media
surface. The second solution involves cleaning of the Y-Arm surface or
optic infrared sensors.
Carriage Axis Error
A ‘carriage axis error’ is the most common error observed on the printer
and is typically caused by an obstruction or an electronic hindrance of the
carriage assembly during travel. Causes of failure include the slide shaft,
encoder strip, trailing cable, outrigger carriage cover bushings, left or right
carriage bushings, cutter, servo motor, service station, carriage belt, frame
tensioner, and spring. Typically the outrigger bushings are clogged with
debris causing the error condition. Remove and clean.
Carriage Axis Failure
The carriage stops suddenly during initialization or during normal printing.
‘Carriage Axis Failure’ is displayed on control panel display.
