e2515AC Exit Section - Grease

[SalesServiceGuy]

I have a e2515AC at a busy earth/ bark mulch supply company.

There is quite a bit of dust floating around that has penetrated the copier.

I do occasionally visit the copier and have attempted to pre-emptively blow out the dust.

I am getting squeaks from the Paper Exit/Reverse section. There is no finisher installed.

I can see the plastic gears are discoloured but not worn. After two years since install, the copier has 125k click on it.

Image quality is good. Everything works well but there is an annoying squeak coming from the Exit section. The office workers sit right next to the copier.

What lubricants should I use particularly around the metal bearings/ bushings?

remove and clean the bushings. if you are in a filthy environment i wouldn't put anything on them. (oil and dirt make an effective grinding compound, throw a little developer and toner in there and it turns to paste.)

On oil impregnated bronze bushings I use TriFlow. On the plastic bushings I prefer to use nothing, but if I squeaks: TriFlow. For the idler wheels with the integral molded plastic shaft I'll use a thick, clay based grease, Mobilgrease 28, that won't run off the first time it warms up. For those old-timers, it's an excellent substitute for the hard to find and expensive IBM23 used on older Lexmark devices. =^..^=

On the Oilite bushings I use SuperLube (Synthetic PTFE) but I pre-lube them in a small vacuum chamber and wipe off any access on the outside as well as re-dressing the shafts with some worn out Scotch Brite.

Plastic shafts I use Molykote.

The plastic, nylon and other Dinasaur squeezing's bushings, noting; they are generally designed to 'shed' and self lubricate.

The other lubricants I use are Cemplex710 for fuser bearings, high torq plastic and metal gears (mostly in folder inserters), re-lubing oneway bearings.

Inside Toshiba fusers, I only use the stuff Toshiba sells to put in them though I know there are other solutions for that, I don't use it often enough to need as it's generally cheaper to have Hytec rebuild the fusers now.

I had 4505's which share a lot of things in the Sing20 machines. I would have squeaks and finally tracked it down to the plastic rollers in the exit
section. Dab of moly 30 would stop it. Hope that helps.

I find the most common source of squeaking is not the metal parts at all but rather where plastic meets metal, in particular, the pinch rollers indicated by the number 5 on the parts diagram above. I usually remove them from the shaft and give both the rollers and shaft a good clean then apply some molykote (white) grease to the shaft before putting the rollers back on (you will see a groove on the shaft intended to hold grease under each roller). If I'm being lazy then usually a squirt with nearly any non-drying lubricant will also do.
