[Electrical] HP LaserJet / Transfer Roller Bushing

[Chromatik]

In HP LaserJet 3200/3500/3600

Someone tried to lubricate the Transfer Roller Bushing?, Think it necessary? what kind of lubricant?.



This course, this is an electrical contact and should not be isolated, also consider this material need not be lubricated, but still wanted to consult

Can't go wrong with a little bit of conductive grease. You can get small tubes at auto parts store or electronic supply.

Sorry 13Fusion, but yes you can go wrong with conductive grease, but not in this case. I run transfer bushings dry whenever possible. If they squeal then just a pinhead spot of th conductive stuff.

Conductive grease can create all kinds havoc on drum grounds, primary charge contacts, drum heater pins, and modular connectors. I have had a lot less of these sort of problems since I have started thinking about the application, and using the absolute minimum. =^..^=

Of course you're right...

...but most techs know when too much is bad and where to use the stuff!

I remember I didnt have any one day...and had to scrape some off the old one, replaced the transfer roller and the bushing since a user sliced it all with a knife thanks to a stuck label!

I put a drop of 3in1 oil on my finger and lightly coat the shaft to reduce friction.

That doesn't sound right.

Just a light coat of lube will slow down the wear in the bushing.
Grease just attracts toner and dust that turns to a sticky paste.

That doesn't sound any better.

Must be my sick mind.....I have been doing this too long.

I agree with this comment 100%.

I've never recommended lubricant or grease on transfer roller bushings. Just make sure there is no buildup on the shaft. If you absolutely must lubricate ...um a little bit of triflow applied to the roller shaft and then wiped nearly dry is good.
