HP recommends a plain old water (a damp cloth) to
clean printer rollers. I
just cleaned the rollers on my DeskJet 820ce and the paper feed is much
improved. It remains to be seen how long it lasts this way, though.
Cleaning isn't the issue- deglazing is. Rubber rollers become
glazed on their surface, and whether it's from picking up dirt
and dust or because the rubber simply fuses chemically at the
surface I don't know. But traditionally, cerbon tetrachloride
was used for this purpose. I also used it to highlight watermarks
in vintage postage stamps.
