What This Error Means

RICOH Error Code 59 indicates a problem with the printer's fusing unit, which is responsible for permanently bonding toner to the paper.

Detailed Explanation

Error Code 59 on RICOH printers points to a critical issue within the fusing unit, also known as the fuser assembly. The fuser uses heat and pressure to melt the toner powder onto the paper, making the print permanent. When this error appears, it typically means the fuser is not reaching its optimal operating temperature, or there's a sensor malfunction preventing the printer from confirming the fuser's readiness. This can be due to a faulty heating element, a broken thermistor (temperature sensor), or a problem with the fuser's motor or gears preventing proper rotation. Common causes for this error range from simple power fluctuations to more severe hardware failures within the fuser itself. Over time, components like the fuser lamp, thermistor, or even the fuser film can wear out or become damaged. The printer's internal diagnostics detect an anomaly in the fuser's expected operation, such as an inability to maintain temperature or an unexpected temperature reading, and then trigger this error code to prevent further damage or poor print quality. Addressing this error often involves inspecting the fuser unit for physical damage or wear.

DIY Troubleshooting Steps

Try these steps before calling a specialist

1
Turn off the printer completely and unplug it from the wall outlet. Wait for at least 15-20 minutes to allow the fuser to cool down completely, then plug it back in and power it on.
2
Open the printer's front or side cover (refer to your printer's manual for exact location) and carefully locate the fuser unit. It's usually a large assembly with warning labels about heat.
3
Gently remove the fuser unit (if easily accessible and removable) and inspect it for any obvious physical damage, such as torn film, jammed paper, or foreign objects. If you find paper, carefully remove it.
4
Check all connectors and cables leading to the fuser unit to ensure they are securely seated. Sometimes a loose connection can cause temperature reading errors.
5
Ensure the printer is plugged directly into a wall outlet, not a power strip or UPS, as insufficient power can sometimes prevent the fuser from heating correctly.
6
Perform a firmware update if one is available for your printer model. Sometimes, software glitches can cause sensor misreadings.
7
If your printer has a 'consumables' or 'maintenance' menu, check the fuser's remaining life. If it's near or past its expected lifespan, it might be due for replacement.

When to Call a Specialist

You should call a specialist if, after performing all the DIY troubleshooting steps, the error code 59 persists. This error often indicates a hardware failure within the fuser unit itself, such as a burnt-out heating lamp, a defective thermistor, or a motor issue. These components are typically not user-serviceable and require specialized tools and expertise to diagnose and replace safely. Attempting to repair internal fuser components without proper training can lead to further damage to the printer or personal injury due to high heat and electrical components.
