What causes Ricoh K-C1 All in One Printer to have unstable fusing temperature?
- MMark MilesAug 25, 2025
An unstable fusing temperature in your Ricoh All in One Printer occurs when the fusing temperature doesn't rise 3°C or more within 5 seconds after the fusing lamp has been on for over 8 seconds. This could be due to a defective thermistor or a defective power supply unit. Check these components to resolve the issue.
