'03 fuser noise

Re: '03 fuser noise

As for stripping and re-lubing the inside of the sleeve, forget it it's not worth the effort. The things are jig built and if you pull it to pieces it collapses into a pile fiddly parts and you end up damaging the sleeve trying to get it back together.

Even though I'm not the most experienced person on these sleeve driven fusers (give me a solid aluminium hot roller any day !), I've had a few apart lately, mpc305 type, and greasing the inside seems to make all the difference in the world. From jamming and creasing the belt, to running smoothly. Without grease the lub bar inside the belt acts as a brake shoe inside a wheel, or one end has some lub grease still, and the other end completly dry. Visulise that and you can see how a crinkled belt would happen. They would be no different in any of the machines. I would go ahead and try liberal lubing. If it does fall to bits, as our friend says, well, you lost nothing because it wasn't working anyway.

Andy227 do you mind sharing the name and specs of the grease you use? We have tried lithium grease on th mpc305 range with limited success.

Re: '03 fuser noise

I wonder about that too, i dont believe someone has ever done that succesfully...
I have tried it, but failled (hard)!

hi
lithium cant handle the heat.
i dont use it even on mp6001 fuser gears anymore instead a teflon grease.
There are a lot of high temp greases out there but i know HP has been using the
lubricated fuser sleave design for maybe 20 years and on the older hp4200/hp4300 series they are rated 200k.
I dont do much HP anymore as they became crap wth lasers and boards going bad after 5k..

The heat resisting grease, sold by Ricoh itself:
A257 9300 Grease Barrierta - S552R
I'm not sure, but i think this is the one...
It is VERY expensive!!!

i gotta chime in on superlube and i dont use it on fuser sleeves as it seem to dry up over time.
there are a lot of aftermarket parts dealer like partsmart and others.
I think the printer community has done a good job with the sleeve lube.

Re: '03 fuser noise

I may be wrong, but I do believe there is a tsb currently for the 03 series for a clicking sound due to the fuser drive gears. There are updated gears that reduce adrasion. If that is not the cause then I would clean the stripper plate and possibly replace the fuser sleeve

seemed there was some gap where they moved a bit from the metal

Re: '03 fuser noise

They are both going to need sleeves. One is crinkly in the middle, the other looked great initially, until I noticed that a circle of belt about 2mm from one end had completely separated from the rest of the belt. The gears appear to be fine. A lot of good info in this thread. Thanks for the replies.

BTW, here is the grease Ricoh recommends using on c4503 fusers. This is for 3.5 oz. WTF!

Even buying direct from Ricoh it's still over $230. I think at one point they explained why they switched from the Barierta grease to the Fluorotribo grease which amounted to "it's greasier grease'

Re: '03 fuser noise

When working with a dealer I sourced the Barrierta product direct from Kluber, wait for it, at $800 per 1kg tub! Cheaper than Ricoh but still whopping expensive.

Some specialty items are just gonna be expensive due to the small market for niche products.

I know this sounds silly, but I had some white creamy grease in an unmarked tin that was given to me years ago and I used it, however, there have been a few discussions on these forums regarding grease, and out of the zillions of suggestions, I noted a few. This one seemed decent enough to me and I got the office to order one so we could try it.
Dow Corning Molykote HP-300 Synthetic Fluorinated PFPE Hi-Temp Grease Fuser 20gm 36663602176 | eBay

"Dow Corning Molycote HP-300 synthetic fluorinted PFPE Hi-temp grease" If I compare with Ricoh Barrietta, it looks the same consistancy and colour, and the price is logical, and am sure it will work. All I know is that I had three mpc305's in the past week jamming in the fuser, and the sleeves were not turning in synch with the pressure roller and when a paper is fed in the sleeve by hand, it almost comes to a standstill. Opened up, completely dry on the bar, lubed, and the whole thing was as smooth as a silk, with no jamming whatsoever. I have concluded that dry sleeves are the major cause of fuser jams (at least on the 305's). The reliance of these fusers on good greasing seems underestimated. Also, the grease that comes with these 'non-original' sleeves is probably going to be some cheap rubbish. They've been getting cheap crap Chinese sleeves, and the grease provided is actually not grease but a little syringe of silicon oil....
