Re: mp2852 pressure roller worn prematurely

Dear colleagues,
Sorry to interrupt your conversation here, but as I understand well it is apparently not common that the PR is melting on the HR. Or was it?

No, it's very uncommon. I'd rebuild the fuser with new rollers, thermistors and stats. It's not happy about something.

Why in Hells name have any of you got customers with old Russian models still out in the field.....get your sales guys and gals out there and sell some new kit.

If only it were so simple.

vey uncommon for it not to code out before it would be able to melt.
which it why it was suggested that it may have been reset multiple times for that to happen.

I have had it happen once. The customer had been told how to clear fusing codes. They were getting SC546 and kept resetting the code and trying to use it. This caused the temperature to go high enough to met the pressure roller before the faulty thermistor could detect the over heat. Ended up having to replace the main frame side fusing cable to correct the SC 546.

Dear Slimslob,
I guess you are right.
Thanks.
