Xerox OHC Vibration...

[kdw75]

Our 13x19 High Capacity feeder ran quietly for about the first 60K 13x19 gloss cover sheets. Then it started having a loud vibration while feeding the sheets and after doing that for while at around 90K sheets it started mis-feeding. Service stuck in some new rollers and all was well again.

Now at 150K sheets it just started the loud vibration sound again. Does it make sense that the rollers would need to be replaced so often?

The machine, a Xerox 560 and feeder, are only two months old.

This happens to us as well. I'm not sure what the cause is but for us it never results in a jam. My guess is the mis-feeding and the noise were unrelated and just a coincidence.

But that is just the opinion of 1 non-xerox tech.

It also depends on your stock. Gloss cover , especially if its inexpensive low quality cover stock, on a friction-feed roller system (which, I'm assuming is the feed methodology on a 560) will tend to destroy the feed rollers quicker than other stocks. It's not that the rollers get "worn-down", but rather that the gloss will begin to "gum-up" the rollers rendering them ineffective. If you're running a mid-range production press, the feed methodology is usually vacuum-feed (instead of friction feed), so, the gloss cover stocks don't seem to affect the feed rollers as much.

Thanks for that insight. I will try to clean the rollers. The paper is Polarbear brand.

When you say a mid-range production press are you referring to something like the 800/1000 and up? They are wanting to upgrade us to a J75, but from what I understand it isn't much different except for the speed.

I think the HiCap feeder for the 560 is the same design (maybe not same model) as the 75's and 800/1000. Which if it is the hicap is a vacuum feed. The internal trays would be friction.

I have a 550. Pretty sure the high cap is vacuum feed.

I talked to service and they said that the rollers should last to almost half a million clicks. He then recommended removing and cleaning them. I scrubbed the black upper rollers with a mild solvent mixed with water and the vibration and the feeding problems are gone.

... the rollers should last to almost half a million clicks....

Yeah, if all you run is 24lb bond....

He said he was going to leave me an extra set of rollers just in case.
