    Ricoh NMP C7501sp SC-551

    Hi all

    I have error sc-551 on an MP C7501sp which relates to the thermistors...

    The plastic coating on one of the thermistors is fairly worn away to the metal and was going to change them however in the parts manual I can only find one thermistor listed.

    Can anyone let me know the part numbers?

              I looked in the godawful 3d parts catalog and found AW100110 for a single thermistor on the bottom of the fuser, probably for the pressure roller and AW100130 TEMPERATURE SENSOR:UPPER:ASS'Y Which is two thermistors and two non contact thermistors together. Looks like it goes in the top of the fuser with the fusing belt.
