Ricoh C4501

I have a Ricoh C4501 popping a sc565 code. Replaced pressure roller thermistor, pressure roller lamp and power supply. Does anybody know what else would be popping this code

Re: Ricoh C4501

Move the fuser to another machine, if the code moves as well then it is the fuser, if not it could be a power supply or PSU problem.
Check the continuity of the thermostats, sometimes they can cause some unusual errors. Also, check the temperature of the hot roller in SP mode.

I will go along with ruben on this one. Form experience, open pressure roller thermostat will cause pressure roller thermistor error codes.

X2. 565 on these is a really shitty code and how a machine can run in the first place with a blown stat is beyond me, but they do.
