TOSHIBA Error Code 59
HIGHCommon IssueToshiba Error Code 59: Fuser Unit Malfunction or Overheating
Toshiba Error Code 59 indicates a problem with the fuser unit, often related to overheating, improper temperature, or a mechanical failure.
Error Code 59 on Toshiba printers typically points to a critical issue within the fuser assembly. The fuser is responsible for melting the toner onto the paper, and its proper functioning relies on maintaining a precise temperature. This error can be triggered if the fuser's temperature exceeds safe operating limits, if the thermistor (temperature sensor) fails to report accurate readings, or if the fuser lamp (heating element) is not heating correctly. Common causes include a worn-out fuser unit, debris obstructing the fuser's operation, a faulty thermistor, or issues with the fuser lamp itself. Less commonly, it could be a power supply problem affecting the fuser's heating capabilities or a communication error between the fuser and the main control board. Addressing this error promptly is crucial as continued operation with a malfunctioning fuser can lead to poor print quality, paper jams, or further damage to the printer.
- 1
Turn off the printer completely and unplug it from the power outlet. Wait for at least 15-20 minutes to allow the fuser to cool down significantly.
- 2
Carefully open the printer's access doors (usually the front or side) and locate the fuser unit. It's typically a cylindrical component with warning labels about high heat.
- 3
Inspect the fuser area for any visible paper jams, foreign objects, or toner buildup. Gently remove any obstructions you find.
- 4
Check the fuser unit itself for any obvious signs of damage, such as torn film or dislodged rollers. If it looks severely damaged, it will likely need replacement.
- 5
Ensure that the fuser unit is properly seated and locked into place. Sometimes, a loose connection can trigger this error.
- 6
Close all access doors securely, plug the printer back in, and power it on. Observe if the error clears or reappears.
- 7
If the error persists, try performing a hard reset: unplug the printer, wait 60 seconds, then plug it back in and power it on.
- 8
Consider updating the printer's firmware if an update is available on Toshiba's support website for your specific model, as software glitches can sometimes cause sensor misreadings.
You should call a specialist if the error code 59 persists after performing all the DIY troubleshooting steps, especially if you suspect the fuser unit itself is physically damaged, if you've detected a faulty thermistor, or if the fuser lamp is not heating. Fuser units operate at high temperatures and contain delicate components, so replacement or repair should ideally be handled by a trained technician to prevent further damage or personal injury. If the problem is intermittent or appears to be linked to power fluctuations, a technician can also diagnose power supply issues.
