It is almost the same as a MPC2000-3000 fuser, just a bit bigger.

Check the pressure roller drive gear; these can crack. Check the clutch gear; these can collapse. Also, check the foam roller, if it is damaged around the shaft it will need to be replaced.

The Pressure Roller Bearings need a bit of heat resistant grease to prevent that rattling noise during printing.

My rule of thumb when rebuilding something that I have done before, follow the service manual, step by step.

Me too, that's what the manual is for, and you can save yourself a lot of heartache, once you know the correct procedure, then it's possible to look for shortcuts

I usually do the kit + press roller thermistor. If no long time solution is needed I try cutting some costs and just replace the defect parts.

Re: rebuilding a mpc 2800 fuser

Honestly, these are one of the better fusers Ricoh has come out with. 250K is just breaking it in for the most part. I have had them go 500K+ before without issues.

The advice given by other posters is spot on in terms of checking/replacing the gear and also greasing the bearings.

Don't be so fast to assume on the thermistor on the heat tube (the one with the belt). I have had a fair number of these that do need to be changed from time to time or you wind up with 543 codes. With 250K on it, I would not change it, but this is more of a FYI than anything.

Re: rebuilding a mpc 2800 fuser - pressure roller gear

I can not seem to identify the pressure roller gear in the MPC2800 MPC3300 parts manual.
Does anyone know the part no.?
If I am correct, the pressure roller is the black roller with one lamp, outside of the belt.

Part no. AB014308 I suppose.

Question about the life expectancy of all fuser bearings. How long can they last? Do you replace them when the fuser hits ~250k or they start to rattle?

i usually have the whole kit and change everything.
then save parts that look good in a marked used box..
