This Code means low fixing unit temperature. If the power goes off and on, or Suzy Sec. has a space heater on the same circuit, this could be a false code.
Enter the service mode by keying in the numbers "10871087", on the key pad. enter the number 906, press start, press "execute"on the touch panel. The machine will reboot.
If the code comes back, you either have a bad thermistor, thermostat, or heater lamp. I have only had to replace the thermistor. The Fuser comes in the maint. kit ,so I always have some old ones laying around.

Also check for continuity within the connector cable. If none, remedy or replace the cable. Broken fuser thermistor wire. Measure the resistance. If it is ∞ ω, replace the fuser thermistor. Fuser thermistor installed incorrectly. Check and reinstall if necessary. Fuser thermostat triggered. Check for continuity. If none, replace the fuser thermostat. Fuser heater M or S installed incorrectly. Check and reinstall if necessary. Broken fuser heater M or S wire. Check for continuity. If none, replace the fuser heater M or S.

Error Code C6050

First you must get into the service mode by keying in 10871087
The screen will start blinking - then key 163 and the screen should read cancel or execute -select execute
when it is complete turn unit off then back on and see if that worked, if not buy a new fuser unit. They cost around $150,00 to $200.00 depending on who you buy it from.

Kyocera KM4035 Service Message C6050

the above is incorrect, Kyocera made a mistake by having a thermistor that physically touches the upper heat roller/belt.. it has worn the roller to a point where it throws up the error.. you will have to install a new fixing unit.

I have done over 25 warranty replacements regarding the 4050/5050/2525 etc.
