Common causes

  • 1Use of toner cartridges with faulty communication chips.
  • 2Accumulation of toner dust on density sensors.
  • 3Poor contact between the cartridge chip and printer.
  • 4Failure of the developing unit supply motor.

Solutions

Diagnóstico rápido

Error e020-0000 manifests after attempting to print or copy multiple pages. If you notice toner dust outside the normal area upon removing the cartridge, this confirms internal leakage affecting the sensors.

Solución paso a paso

  1. Remove Cartridge: Open the front cover and remove the 071 cartridge.
  2. Check for Leaks: Inspect the input guide for spilled toner and clean it with a dry cloth.
  3. Clean Contacts: Gently clean the connection pins between the printer and the toner chip.
  4. Reset Sensor: Reinstall the cartridge, ensuring it clicks firmly into place.

Prevención y mantenimiento

Always use original Canon 071 cartridges to ensure the communication chip is recognized by the logic board. Clean the internal optical sensors whenever you replace the toner to avoid false alerts caused by dust buildup.

Cuándo llamar a un técnico

If the error persists after trying a new genuine toner, the internal developing unit may be damaged, or the toner supply motor may need replacement by a professional.

Frequently asked questions

This error signifies that the printer cannot adequately detect the toner supply within the developing unit.

Often, cleaning the toner contacts and the image unit area resolves the issue if it is caused by accumulated toner dust.

Very often. Generic toners may lack stable chips or the necessary electrical conductivity, leading to detection failures.

Perform preventive cleanings whenever replacing the toner to ensure debris does not block the optical sensors.
