I would start with the gears first. Stepper motor
testing can be done by visual inpection by running
through 1 character at a time. Mark each turn when
moving to the next character. This requires diassembly
of the casing and other visual blocking components.
I don't recall if this model has one of these optical position
'belts', if yes, make sure the sensor and belt are free from
debris.
