    True, you can replace the less expensive pm kit (PMB222160K) which includes the ferrite core or the whole fusing assy. (B2234021) which is about twice as much(@ $640 USD last I checked) or modify a p/n 402718 color printer fusing unit which is somewhere between the pm kit and the actual fusing unit. You will have to flip a couple of wires in the harness -no biggie, takes a few extra minutes but worth every penny...

    I work for one of (if not the biggest) ricoh dealerships in the US.

    There are modified sensors now available, which have a wider gap for the flags to go through P/N: AW020190
    Also I've had to reinforce the sensors in place with paper clips wound around them to stop them falling out as easily. Looks ugly, but does the trick.

    There isn't a way, you've got to strip the fuser to see the thermistors in the first place. I suppose a mark on the belt or press roller would give away a damaged or heavily toner caked one.

    Computers are serious tools, Michael!
