Solutions

Diagnóstico rápido

The C-6752 error confirms a scanner movement issue. If you hear a grinding noise while scanning or see this error during startup, the carriage is stuck or obstructed.

Solución paso a paso

  1. Open the ADF tray and remove any debris, paper scraps, or staples that may be caught.
  2. Check the scanner glass for any large obstructions.
  3. Clean the glass with a microfiber cloth to ensure no sticky residue causes resistance.
  4. Restart the printer to trigger a fresh carriage calibration cycle.

Prevención y mantenimiento

Avoid loading damaged or stapled paper into the ADF. Wipe the glass periodically to maintain clear reading optics.

Cuándo llamar a un técnico

If the reset does not fix the issue, the scanner’s internal drive motor or communication cable may be faulty and requires a technician's expertise.

Frequently asked questions

This code means the scanner carriage is unable to complete its initialization cycle, usually due to a mechanical jam or internal obstruction.

Generally, printing functions remain operational, but the scanner and copier functions will remain blocked until the error is cleared.

The scanner is an optical module and does not use toner, but proper cleaning of the glass is essential for consistent scan quality.

Always inspect documents for staples or adhesive before placing them in the ADF tray, as these are the main causes of mechanical scanner failures.
