Common causes

  • 1Excessive accumulation of toner dust on the optical sensor.
  • 2Use of uncertified consumables that leave residue on the transfer belt.
  • 3Worn transfer belt failing to register the calibration mark.
  • 4Electronic failure of the image density sensor board.

Solutions

Diagnóstico rápido

This code indicates that the device failed to detect the calibration mark on the transfer belt. Check for toner dust coverage near the sensor.

Solución paso a paso

  1. Internal Access: Open the front cover carefully.
  2. Sensor Cleaning: Identify the density sensor (a small optical hole) and wipe it with a dry, lint-free swab.
  3. Cartridge Check: Ensure the toner is genuine and securely seated.
  4. Forced Calibration: Restart the calibration process from the image setup menu.

Prevención y mantenimiento

Avoid low-quality non-OEM toners that leak excessive dust. Perform internal cleaning every 10,000 pages to extend the life of optical components.

Cuándo llamar a un técnico

If the error reappears after cleaning the sensor, there may be a mechanical failure in the transfer belt or a broken sensor board.

Frequently asked questions

This code means the density sensor cannot read the calibration patch correctly, often due to toner dust.

Yes, printing is suspended until the system is successfully recalibrated.

Use genuine Xerox B400 toner to prevent excessive dust accumulation and sensor interference.

Clean the internal area every time you replace a toner cartridge to avoid buildup.
