Re: RICOH MPC305 - Heavy Fuser - Grease for Fuser Film

The grease Ricoh sells (Barrierta JFE55/2) works but is a bit pricy. You could see if you can find a small tube of Dow Corning Molykote 41. It has a service temperature of 288 Deg C vs Barrierta at 260.

I replace the sleeve, pressure roller & the 3 gears as a set usually they go about 100k or 2 years

It if the fuser starts making a "farting" type noise that is time to replace the above parts.

What you don't want to do is risk the fuser drive gear wearing down, that is a big job.

Hi there!
After checking the prices for the fuser-parts, we only order the complete fuser, the price is much less.

The complete fuser is cheaper than the parts AND does not take up all the extra labour as well.

Here is one to try. It is actually for automotive breaks but the specs are right. 500 degrees Fahrenheit is 260 degrees Celsius which is the temperature for Barrierta JFE55/2 that Ricoh recommends and sells for a ridiculous price.

Amazon also has a number of suitable greases. Just search amazon.com for high temperature grease all departments. They have Molykote 41 and 44 (200 degree C), DuPont Krytox (good but expensive) and many more.

i think the chemplex is the same lube/grease that they use on the hp 4200/4300 fuser sleaves.

i use to buy the super lube from my local ACE hardware store,it works but it does dry up over time.
any thought on a grease and old style silicon oil mix?
i have a few quart bottles laying around from my ricoh 6513 accounts i use to maintain.

Having used the actual Ricoh grease as well as Chemplex and Krytox, I prefer Krytox. Chemplex just seems too 'goopy', and also leaves a bit of an odour as it first heats up in a machine.

You could try silicon heat sink compound. I use it to pack bearings.

wow havent heard SHC used in years,
many years ago 25 plus on the anaolog minoltas they used triacs for the heat lamps and exp lamps that
you could unscrew and change but only if you applied the compound so they would kool off,on the metal heat plate..
i can remember people using MOBIL 1 but when it got hot it would stink like a chemical plant.poor customers sitting nearby

I used to get it at a local electronics store but they are no longer in business.

TIP check the price of the entire fuser units for these its actually cheaper than changing the sleeves
