Re: Treating Rubber feed rollers for printers?
I just saw this thread now, sorry for not commenting earlier.
I used to work on broadcast video tape machines both at work and as a side business, and was certified as a repair tech for a certain line of very high end color printers. That company was in direct competition with hp and Epson; more the former than the latter due to the target market.
You want to use at least 90% IPA on a linen cloth to clean all rubber rollers. The IPA will clean it, strip off the paper dust and any leftover toner, and won't degrade the rubber beyond its current point. At some point the rubber becomes hard from age and has to be replaced anyway.
Sanding was mentioned above. Only do that if you don't care about the rest of the mechanism downstream of where you sanded a roller. Microscopic stuff will ablate from the roller and be carried into the rest of the mechanism.
It's important not to use any IPA concentration less than 90%, as those products will contain oils and other chemicals which do not do you any favors.
You NEVER want to use any "cleaning fluid" inside a video tape recorder, as it will leave a film which will transfer to the tape, then to everything in the tape path - including the heads! I've cleaned up a number of machines which had this done to them, and it wasn't a cheap job for the customer.
The best thing to have is prepackaged alcohol wipes, as they are always ready to go. The brand I use and still have around is CleanTech, CT806. These have a pre-saturated large linen pad which can take some real abuse as you scrub surfaces, guides, and rollers.
