Common causes

  • 1Dirt on the encoder strip (ink/dust).
  • 2Mechanical obstruction on the printhead rail.
  • 3Damaged printhead position sensor.
  • 4Premature wear of the carriage traction mechanism.

Solutions

Quick Diagnosis

If you hear a thud or the printhead moves abruptly, SC-1203 will trigger for safety. Check that the encoder strip does not have ink smudges.

Step-by-step Solution

  1. Encoder cleaning: Use a soft cloth lightly dampened with distilled water to clean the transparent encoder strip.
  2. Sensor reset: Turn off the machine so the printhead returns to its home position.
  3. Clean load: Ensure there are no physical obstructions in the sliding rail.

Prevention and Maintenance

Regular cleaning of the encoder strip is vital to prevent positioning errors. Avoid using strong solvents that can erase the strip marks.

When to call a technician

If the strip is scratched or the printhead sensor does not detect the marks, replacing the encoder strip will be required.
