Solutions

Quick Diagnosis

Error C1-001 occurs when the scanner's internal calibration fails due to blocked sensors. If your images have streaks or the scanner stops immediately after initiation, cleaning the glass is the first corrective step.

Step-by-Step Solution

  1. Unplug: Power down the device to prevent any movement while cleaning.
  2. Access: Open the scanner cover to expose the reader assembly.
  3. Clean: Wipe the glass with a microfiber cloth to remove dirt or adhesives.
  4. Secure: Ensure the lid is locked in place after cleaning.

Prevention and Maintenance

Perform maintenance every 500 scans to avoid dirt build-up. Always use clean documents without adhesive residue.

When to Call a Technician

If deep cleaning does not resolve C1-001, the internal LED lamp might have failed, needing a professional diagnostic visit.
