fuser fixing film grease

If one wanted to move a fixing film from one fuser to another, is there some kind of grease you could get at the hardware or auto parts store that would be ok for getting the film on the "new" fuser?
No. It's a special high-temp grease formulated for the fixing films.

Moe sells some good grease here on this site, in 2 sizes.

Moe,
Ok, thanks.

Anonymous,
Thanks, I didn't know those were there. Unfortunately that is not a practical choice for me. I have 1 fuser to deal with. That leaves a significant amount of extra grease that I have nothing to do with and there is shipping in addition to the listed costs.
The one grease tube/tub is the same price as a film repair kit which includes a new sleeve and the proper dose of grease for it.

I am getting educated in other threads, my fuser may not be the problem. If it is, I will probably just scrap the entire fuser or possibly try using powdered graphite to move the sleeve to another fuser. The powdered graphite may not be as good as the grease, but I have seen it suggested as an alternative by someone who has a very good reputation in regard to printer/cartridge repair. I can get it in a small quantity locally which gets me out of shipping costs and storing unneeded materials.

I've seen people suggest all kinds of stupid things, Acetone, Ammonia, WD40, but powdered graphite? You do realize that graphite is abrasive, not to mention it is loose and wouldn't properly lubricate the sleeve. If you want a sample packet of the grease, click on my name to email me and I'll give you ordering instructions.

Thank you for the offer on the grease packet. I will keep that in mind if I need to proceed with the sleeve transfer.

I would like to point out that graphite is not a "stupid thing" here.

Graphite is a lubricant, not an abrasive. While it is a powder, it is a very "sticky" powder. The source for the suggestion was a qualified and respected "web helper" who used that technique in his/her own business for some time.

Just can't resist. If graphite works so well, why don't the engineer's that design these units use graphite in the first place? Believe me, graphite is much, much cheaper than the proper fuser lubricant and we all know that these printer companies will skimp whenever possible as they built millions of these units. Can you imagine the boost to their bottom line?
It is a bit trying to spend time helping people with their questions only to have them question our advice. If you choose not to believe us, then take your machine into a local repair facility and have them repair it for you.

I'm still working on the graphite being non-abrasive. Both graphite and diamond are pure carbon. Diamonds are the hardest substance known to occur in nature, definitely abrasive. So, graphite, even though a softer form of carbon isn't abrasive? True, it acts like a lubricant on metal to metal surfaces, but metal to a soft plastic film. I'm also wondering how you would contain the loose powdered graphite between the film and heater assy. without it pouring out the ends. If that isn't stupid, then I don't know what is. I don't know where you got the idea that this person has a good reputation in cartridge/printer repair, but he'd probably get quickly tossed off this forum like a certain troll from Australia did for dispensing bad advice.

You have to use the silicone grease on the sleeves-even Hp and canon had problems when desiging and making these fusers run beyond
100,000 pages.

graphite has it's place and uses but not in fuser assembly rebuilds
we are using chemplex 710 grease with good results.

Chemplex 710 grease is absolutely the worst grease we ever tried in fixing film assys. It might have its uses, but definitely not in fuser rebuilds. All the fuser remanufacturers switched to the Uniflor grease when it became available. It's 10 times the cost, but it will withstand the high speeds in modern fixing film assemblies. They're both Nye products.

I think I know where the novice got the idea of using graphite on a fuser sleeve --- his source was a cartridge refiller co. & they use a powder lubricant on the toner drum after re-filling it so it makes the drum turn smoothly -- usually a white or silver powder that looks like a graphite & we call the fuser sleeve a fuser roller & he possibly thought the graphite would serve the same function as on a re-man toner drum. It has to be a grease & able to withstand 300 degrees without drying out or liquifying & running out of the sleeve.

The outer surface of the sleeve runs at 392 degrees, (in normal mode),so I suspect that it's just a little hotter inside the sleeve.

I've used the Chemplex 710, but only in slower printers like the 5P/6P, the Unifloor is definitely superior.

Thanks to all for the comments.
Given the age of these printers and what I am now seeing on eBay listings, this is probably like learning about windows 98, but I appreciate the opportunity to learn a bit more about them and possibly be able to extend the life of ones that I am using.


Anonymous,
Re fuser life

I am experiencing a very mixed bag on fuser life on these printers.

I had one fuser that went 250K + copies and another that went 150K plus copies. The sleeve was still in one piece on both of these, it failed because of a "stripe" in the printing surface. I am not sure if this came from normal wear or was a result of some improper "jammed paper" removal.

I have another fuser that failed at a little over 60K copies. The film on this one somehow started sliding to one edge of the fuser and the film just started shredding on the edge. No idea what caused that. I have some others still going strong, I will now be watching with interest to see if they make and exceed the 100K mark.

After doing some research,found out all of the fuser remanufacturers are having problems making fusers run consistently to rated life without
problems. if they say all is well they could be lying.

thanks for the post about the uniflor grease.
some parts houses are using 9172 and 8912
and are testing some Dow chemical product as this is what Hp uses?

Good thread, it will be interesting to see what the new hp's run like.

I know that Canon has had problems as well
so far the image runner 3300 series is doing well
and we will keep a close eye on the high speed 5070 and
others. they use the same type of fuser technology.

HP had a run of fusers for one printer that had a bad flange from the factory, they all shredded the sleeves early.

PS; You can click on my name and email me if you have a sleeve question for a specific model number, or just start a new thread, since this one is dedicated to grease.

Hi All,

New to the forum... I've been using the uniflor grease to fix fuser films for a while now but am suddenly running into trouble with it. The fusers are coming back with the films torn or jammed. On closer inspection of the residue of the grease, I am seeing that is has turned into a gooey/gummy gel and is no longer lubricating the sleeve.

The consistency is perfect when it is beeing applied.
I have tried using both the 8172 and 8192 to no avail.

Any suggestions?

Much appreciated...

I believe the 8172 has been discontinued. My supplier told me that Canon/HP uses the Uniflor grease on their fusers at the factory. They claim they contacted HP with a fake grease in the eye claim and asked for the MSDS which pointed at Uniflor as the supplier. The grease won't stay liquid as the heat will solidify it. If you ever took apart an OEM fuser that had 200,000 copies on it, you'd see that grease had solidified as well. We haven't experienced the failures you're having. Maybe some of the other forum techs will voice their opinion. - moe
Using uniflor grease on the hp and canon fusers with good results
no room for shortcuts here unless you have spare time and money.

From a service standpoint you want to rebuild the fuser and not see any failures for as long as possible.one thing that will cause ripped sleeves is when the customer pulls a paper jam out of the printer at an angle instead of straight out.

there is a special grease for fuser film that can handle high temperature

Telecommunications are tightly in our daily lives. Everyone coming home in the evening wants to enjoy a good movie or TV series. But to enjoy it you need to choose a good provider. You can read the reviews as well as find out the directv phone number to find out the advantage of this company and their rates.
