Solutions

Quick Diagnosis

If the carriage is stiff or resists manual movement (when powered off), there is an physical obstruction preventing it from sliding along the track.

Step-by-step Solution

  1. Unplug the printer.
  2. Manually slide the carriage side-to-side to identify the friction point.
  3. Remove any paper scraps or tangled ribbons.
  4. Clean the guide rod using a clean, dry cloth.

Maintenance and Prevention

Routine cleaning of the metal guide bar is key. If the rod feels dry, apply a minimal amount of light machine oil according to manufacturer guidelines.

When to contact a technician

If the carriage moves freely but error P-02 persists upon startup, the position sensor or motor is damaged.
