Common causes

  • 1Data corruption: Interrupted memory writing during operation.
  • 2Logic Board failure: Defective storage chips on the board.
  • 3Outdated firmware: Known bugs in older software versions.
  • 4Heavy traffic: Queue overload causing memory buffer errors.

Solutions

Diagnóstico rápido

The E602 error often occurs after a power outage or unexpected disconnection while the printer was active. It is a system-level software alarm.

Solución paso a paso

  1. Unplug for at least 20 minutes.
  2. Clear all pending jobs from your PC queue.
  3. Boot up without network cables connected.
  4. Reset to factory settings if the interface loads.

Prevención y mantenimiento

Avoid force-shutting down the unit while the 'Processing' indicator is flashing. Keep your firmware updated to ensure robust memory handling.

Cuándo llamar a un técnico

If the error loops after a full reset, the main circuit board may be physically defective.

Frequently asked questions

The E602 code indicates a failure in communicating with the internal storage or memory, typically caused by file corruption or a hardware board fault.

No, it is not related to the toner (Canon 071). It is exclusively a software or mainboard-related issue.

Always power off the printer using the physical button. Never pull the plug while the printer is processing data.

If a factory reset doesn't work, the main board likely requires repair or a professional firmware re-flash.
