  • 2Temporary configuration data corruption.
  • 3Outdated system firmware version.
  • 4Interrupted data transmission via connection interface.

Solutions

Diagnóstico rápido

If the error occurs immediately upon sending a job, the memory buffer might be unable to process the file's complexity. A quick power cycle often clears the temporary state.

Solución paso a paso

  1. Power Cycle: Fully disconnect the printer from the power source for 60 seconds.
  2. Clear Queue: Delete any pending print jobs in your OS printer queue.
  3. Test Print: Try printing a simple test page to verify connectivity.
  4. Firmware: Check if a newer version is available from the support portal.

Prevención y mantenimiento

Avoid overly complex high-resolution graphics if unnecessary. Regularly updating firmware improves how memory is allocated for print jobs.

Cuándo llamar a un técnico

If the error code remains visible upon startup despite clearing the power, the physical memory chip may be failing.

Frequently asked questions

This code typically indicates a read/write issue with the internal DRAM or Flash memory during processing.

A standard reboot won't, but a factory reset will clear user-saved labels or fonts.

Use authentic Brother thermal transfer ribbons to ensure stable operation and reduced buffer load.

Updating the firmware is highly recommended if the error is frequent, as it often optimizes memory handling.
