Abstract

This invention claims the use of a tacky medium to be used, as needed, to clean the fuser rolls in a laser printer. Typically, the hot-roll and the back-up roll in the fuser station become contaminated with toner and paper dust after some period of use. Eventually the print and performance are affected.

Fuser Roll Cleaner Sheet

      This invention claims the use of a tacky medium to be
used, as needed, to clean the fuser rolls in a laser printer.
Typically, the hot-roll and the back-up roll in the fuser station
become contaminated with toner and paper dust after some period of
use.  Eventually the print and performance are affected.

      In this invention, a sheet of some medium would be fed through
the printer in the same fashion as a normal sheet of paper and the
resultant tackiness would clean the rollers. This special sheet could
be attached to the cartridge and automatically fed through the fuser
with every cartridge change.  It could also be fed through the
printer on an as-needed basis.

      A heat-activated adhesive was applied to paper and has been
shown to clean the back-up roll of fused toner.  Other materials that
become tacky with heat or pressure could be used.

      This presents several advantages over the prior system where no
cleaning can occur.  If, due to some unforeseen problem, the fuser
rolls become contaminated with toner, they can be cleaned by the
customer.  Used on a regular basis the fuser rolls would never become
contaminated.  This invention could also allow the use of much
cheaper fuser rolls, since contamination can be controlled.
