Diagnóstico rápido

Error 900.00 is a system-level fault code. If the message appears upon startup, it suggests a corrupted kernel or flash memory issue. If it occurs intermittently, it is likely caused by the printer's inability to interpret a specific driver command or a corrupt document file.

Solución paso a paso

  1. Power cycle: Disconnect all data and power cables, wait, then reconnect.
  2. Network isolation: Disconnect the printer from the network to ensure no bad data packets are triggering the fault.
  3. Firmware upgrade: Use the official Lexmark tool to flash the latest firmware onto the printer.
  4. Memory check: If the printer has added DIMMs, remove them and test again.

Prevención y mantenimiento

Keep the printer's firmware updated to ensure compatibility with modern document formats. Avoid overloading the printer's print spooler with massive files. Ensure the device is connected to a stable UPS to prevent sudden power loss that can corrupt memory.

Cuándo llamar a un técnico

If the machine fails to boot even after a firmware re-flash, the printer board (system card) is likely defective. This is a professional repair procedure and should be handled by an authorized technician.
