Common causes

  • 1Voltage surges damaging internal RAM sectors.
  • 2File corruption due to an improper forced shutdown during power loss.
  • 3Natural degradation of memory chips after years of heavy usage.
  • 4Loose connection on RAM modules seated on the main board.

Solutions

Diagnóstico rápido

Error 601 appears as a startup system message. If the machine cycles continuously, confirm that power supply stability is not the underlying issue before troubleshooting internal memory.

Solución paso a paso

  1. Hard Reset: Unplug the printer and press the power button for 20 seconds to drain all residual power.
  2. Component check: If removable RAM modules are present, remove them and clean the contacts with a soft eraser before reinserting them.
  3. Firmware Restore: Access service mode to attempt a firmware re-installation if supported.
  4. Factory Reset: If you can reach the menu, attempt to reset all settings to factory defaults.

Prevención y mantenimiento

Always use a high-quality voltage regulator. Avoid shutting down the printer directly from the wall; always use the 'Shutdown' command on the touchscreen.

Cuándo llamar a un técnico

If the error 601 persists after hard resets and firmware updates, the main board may have physically damaged memory sectors requiring board-level repair.

Frequently asked questions

Error 601 is a system code indicating a failure in reading or writing to the RAM or internal hard drive of the multifunction device.

If the error persists, you might lose stored print jobs, but the base configuration can usually be restored via firmware reinstallation.

While this is a memory error, using original cartridges prevents the CPU from wasting resources processing toner detection faults.

Keep the printer connected to a UPS or voltage regulator to prevent surges that could corrupt internal data storage.
