Afternoon. Quick question.

I came to a service call and noticed a history of fuser errors. I just wanted to see if the thermistors are dirty and I noticed they are not touching the heating element. Now on my experience with Brother, Sharp, canon, and HP. They always touch the heating element. Is this normal?

Take a look at the following history, a picture.





And



So, this is my first Samsung Fuser disassembly so I'm not familiar with the engineering. Any advice would be greatly appreciated.

There are two kinds of thermistors. Kyocera uses some non-contacting thermistors. The rest are contacting thermistors.

This is a contacting thermistor. Yours must make contact to work properly. =^..^=
