HP 3015dn issues

[Big Al]

We are having strange problems with the fusers in the HP3015dn. We get an error that the fuser is too hot as soon as we turn it on, which seems like the thermistor has gone bad. Others give us a Jam in Fuser Area but the paper present flag is working fine. It looks like the sensor is bad, which seems unusual because in the past these sensors did not fail, at least I don't remember a case where it was the sensor. These are low page count units.
Thanks,

It seems that if the flag at the output of the fuser is OK then the problem may be a "Brand-X" refilled cartridge. Not all refilled cartridges, just some of them. No idea why! The error is: 13.20.00 Jam at the fuser.

There is also a flag in the registration assembly that can trigger a 13.20.00 error, we've seen on some brands of aftermarket toner the plastic shells aren't formed consistently and occasional warps/protusions of the plastic will toggle that flag. BTW PrinterTechs' toners don't do that ;-)

Thanks Steve! I thought we were lost in the Twilight Zone somewhere!
