Solutions

Diagnóstico rápido

Error 900.00 typically indicates a firmware crash. If your printer becomes unresponsive during a job, it is likely a software conflict. Check if the error persists after removing all network cables to see if an external print job is the trigger.

Solución paso a paso

  1. Power Cycle: Turn off the printer using the main switch and unplug it from the outlet for 60 seconds.
  2. Clear Memory: With the device unplugged, the residual power dissipates, often clearing temporary cache issues.
  3. Check Connection: Restart the printer without any cables connected to ensure the error isn't coming from a workstation.
  4. Firmware Update: If the device boots correctly, access the web interface to check for newer firmware updates.

Prevención y mantenimiento

Perform regular firmware updates via the manufacturer's support site. Ensure the printer is connected to a stable power source using a surge protector to prevent voltage dips that can corrupt the operating memory.

Cuándo llamar a un técnico
