Solutions

Diagnóstico rápido

Print errors are often intermittent. Why does my Brother MFC-L6800DW have a print error? Often, it is just a network communication hitch or a tiny piece of paper caught near the drum unit that triggers the sensors.

Solución paso a paso

  1. Cancel all pending print jobs on your computer.
  2. Power off the Brother printer and unplug it for one minute.
  3. Open the front cover and remove the drum and toner assembly.
  4. Inspect the internals for any torn paper scraps.
  5. Reinstall the toner cartridge firmly and restart the device.

Prevención y mantenimiento

Prevent dust accumulation by using a dust cover if the printer is rarely used. Always use paper within the recommended weight range (60-105 g/m²) and ensure the toner clicks into place to prevent leaks.

Cuándo llamar a un técnico

If the error remains after cleaning the internals and clearing print queues, there may be a fault in the mainboard or the primary drive motor.
