Solutions

Diagnóstico rápido

When the error 0x33 appears, the scanner unit is likely in a stuck state. If the printer attempts to initialize but emits a noise, it confirms a physical blockage. Understanding what does error 0x33 mean allows you to troubleshoot the issue efficiently.

Solución paso a paso

  1. Reboot: Turn off the printer and disconnect from the wall.
  2. Checkpath: Ensure no physical debris is inside the scan assembly.
  3. Sanitize: Use a soft, lint-free cloth to clean the scanner bed.
  4. Reset: Use the menu to return to factory defaults.

Prevención y mantenimiento

Keep the printer bed free of dust. Never force the lid or place heavy items on the scanner as this can misalign the internal optics.

Cuándo llamar a un técnico

If the scanning light remains off after the reset, the CIS module or internal cable has likely failed and needs replacement.

Frequently asked questions

The error 0x33 indicates a fault in the CIS scanner module, usually caused by movement blockage or a failed light sensor.

If you only need printing, the device may continue working, but it is better to fix it before the scanner mechanism locks completely.

Use the 812 series; original consumables are essential for maintaining stable internal system communication.

Use a microfiber cloth with a small amount of isopropyl alcohol. Avoid spraying cleaner directly on the glass.
