Re: MPC 2500 with 553

The thermostats in front of the fusing belt are unstable/old - we changed them and fixed the problem.

Did you not read sandmanmac's reply to garwen? Please do not post to dead threads.

Thanks s -slob..... If changing thermistors is the only ongoing advice techs can get from this site on the SC553 issue, then I see no valid reason not to update these poor guys when an alternative / better idea comes along. Its a perennial problem and has caused me and many colleagues strife over the years after having changed EVERYTHING (else) in the Fuser assembly and no improvement..... (except a worn sponge roller !!).

That's a good and kind thought, but at least I've found that if you have something new to add you'll help more people if you start a new thread rather than resurrect an old and abandoned thread. At least if you can explain what needs to be done and why in a clear and concise manner. Which you did.
If you want to include an abandoned thread you can always add a link to it in your post.
Just my two cents.

Thanks for the heads up. I'm fairly new to this help site, so I welcome your suggestion(s).
BTW.... as you may have gathered, I'd changed everything apart from the plastic housing to no avail....except the Sponge Roller because I couldnt believe it could be that causing the problem !!

Years ago we had an MPC 2500 fuser thermostat/sw that appeared to reset it's self when cooled.
Nearly drove us to drink. We replaced all thermostats in the fuser unit and problem solved.

There was also a problem with the slow operation of the "exhaust fan" situated at the front upper right under the control panel.

Re: MPC 2500 with 553

Thank you, I know there can be many reasons for that error code, however i just described my experiences with SC553 after having done so may "normal" things to fix it. Maybe its a coincidence.... who knows. But the sponge roller seems to have been the final answer in 3 cases so far. Don't ask me what's wrong with the sponge roller ...other than worn down .7 mm in diameter. "When all else fails, it's whatever is left that's the answer" Cheers

I assume the fuser belt doesn't turn normal with the rollers when the sponge roller diameter gets smaller, and therefore generates hot spots on the fuser belt or thermostats/sw. I've stretched the pressure springs once or twice to get them going.
