Introduction

Ricoh copiers are workhorses in busy offices, but even the best machines occasionally throw error codes. When that happens, it can grind productivity to a halt. This guide will walk you through the most common Ricoh error codes, what they mean, and how to fix or reset them — with screenshots where possible.

⚠️ Note: Some fixes involve accessing service modes. Proceed carefully, and contact your service provider if you’re unsure.

🔧 Error Code: SC 542 – Fusing Temperature Warm-Up Error

What It Means:

Your copier’s fuser unit failed to reach operating temperature within a specific time. Common after a power surge or if the machine overheated.

How to Fix:

  1. Hold down the “Clear Modes”, then press “1-0-7”, and hold “Stop” until the screen changes.

  2. Select System SP

  3. Open the front panel of the copier

  4. Turn off the main power switch (not just the control panel).

  5. Restart the copier

When to Call Support:

  • If the code returns after reset

  • If you smell burning or see paper jammed in the fuser

🔧 Error Code: SC 546 – Fusing Unit Pressure Roller Thermistor Error

What It Means:

A thermistor in the fuser is reporting abnormal readings.

How to Fix:

Try the same reset steps as SC 542 above. If it fails:

  • Check for debris or warped paper in the fuser unit

  • Let the unit cool down fully before restarting

When to Call Support:

  • Repeated errors after reset

  • Visible wear or damage to fuser components


🔧 Error Code: SC 899 – Application Software Error

What It Means:

A software-related crash, often caused by incompatible print jobs, corrupted files, or communication errors from a PC.

How to Fix:

  1. Power off the device completely.

  2. Disconnect network cables or USB devices.

  3. Restart the machine.

  4. Reconnect devices one at a time.

Pro Tips:

  • Update your Ricoh firmware and drivers

  • Check for corrupted PDFs or large file print jobs
