  • 2Position sensor (home sensor) broken.

Solutions

Diagnostic

If the error appears immediately upon turning the device on, listen for a jammed motor sound. If the carriage attempts to move and bumps against physical limits, it is an SC121.

Step-by-Step Solution

  1. Visual Inspection: Ensure there are no foreign objects under the scanner cover.
  2. Rail Cleaning: Clean the rails where the carriage slides with a soft cloth.
  3. Forced Restart: Power off, wait a minute, and turn on. The equipment will try to perform a re-home.
  4. Cable Check: Ensure the machine has not been hit recently.

Prevention and Maintenance

Do not place heavy objects on the scanner cover; this can bend the axis and jam the carriage. Perform a glass cleaning monthly.

When to Call a Technician

If the carriage does not move at all or the error reappears after checking for obstructions, the scanner motor or position sensor are damaged.
