Get message of fuser low therm 1F
One of the two small thermostats, that are called "snap-action disc thermostats" and control the electricity flow to the fuser lamps, has likely gone bad. If you are feeling generous to the money pit governed by Konica-Minolta, you'll need to replace the fuser unit. Otherwise, you'll probably need to locate and replace the bad thermostat. If you are not electronics saavy, I recommend taking the fuser unit to an electronics shop and asking them to check for and replace any bad thermostats.
As an explanation, these thermostats work just like the thermostat for a typical home central heating system. While in use, they keep the fuser temperature between 130 and 150 degrees by turning the fuser lamps (the parts that heat up the fuser) on and off. They do this by allowing electricity to flow to the fuser lamps until the temperature of either thermostat reaches 150 degrees. Once that happens, the thermostat will turn off electricity to the fuser lamps, allowing the temperature to cool back down to about 130 degrees. Once the temperature returns to 130 degrees, it allows the electricity to flow again to repeat the process.
