Diagnóstico rápido

The SC990 code is a "software error." It means an instruction sent to the processor could not be executed. This often happens when sending complex PDF files or documents via network protocols that the printer's internal memory struggles to process.

Solución paso a paso

  1. Forced Restart: Power off, unplug for 30 seconds, and hold the power button for 10 seconds to drain static energy.
  2. Clear Queue: Clear all pending documents in your computer's print queue.
  3. Network Reset: Disconnect the Ethernet/USB cable and restart the printer.
  4. Drivers: Reinstall the official driver if the error recurs when printing from specific applications.

Prevención y mantenimiento

Avoid sending excessively large documents in a single batch. Ensure your network cabling is stable. Official Ricoh firmware updates are essential for optimizing memory management.

Cuándo llamar a un técnico

If the error appears constantly even when the printer is off-network, the main board memory may have a physical defect requiring professional replacement.
