Question about Minolta EP4000/5000 CS/PRO Copier
This code means that you have a failure of a part in your fusing unit. The fusing unit is the assembly that gets hot and "fuses" the toner onto the paper. It is located right where the paper exits the copier. The most common part failure in this unit is the thermal fuse. As it's title suggests this part is a fuse which is suppose to blow if the fuser overheats. They usually just fail due to age. There are 2 other possibilities although not nearly as common as the thermal fuse. The other 2 possible failures are the thermister which reads the temperature of the unit and the heater lamp which actually provides the heat.
The thermal fuse is a cheap part at around $5.
You will most likely need a service person to come out and diagnose the problem and repair it. Unless you are mechanically inclined and have a service manaul you might have a hard time getting the fuser out of the machine and dis-assembled in order to replace the parts. There is also a specific reset procedure that must be followed in order to clear the C0500 from memory after repairs are made.
Good Luck and Thank You for using Fixya.
