Abstract

A safe, effective cleaner for the removal of toner on electrophotographic machines has been found. The solvent, tripropyleneglycol monomethyl ether (TMP), in singular use, was found to remove toner of varied polymeric forms from the surfaces found on a typical electrophotographic machine. Typical polymers used in toner would include styrene acrylates, polyesters and polyurethanes, all of which are removed easily with the solvent.

Cleaner for Electrophotographic Machines

       A safe, effective cleaner for the removal of toner on
electrophotographic machines has been found.  The solvent,
tripropyleneglycol monomethyl ether (TMP), in singular use, was found
to remove toner of varied polymeric forms from the surfaces found on
a typical electrophotographic machine. Typical polymers used in toner
would include styrene acrylates, polyesters and polyurethanes, all of
which are removed easily with the solvent.

      This solvent provides the following benefits:
      -    Dissolves toners even when fused onto surfaces.
      -    Has a high flash point and can be applied directly
           to heated surfaces without fear of incurring a
           fire hazard.
      -    Will not attack many of the materials used in a
           typical electrophotographic machine.  Such
           materials that would be encountered include
           polyether imides, silicone rubbers, polyphenylene
           sulfide, and polyethylene.
      -    Has low odor, low toxicity and is not a skin
           irritant.
      -    Is completely miscible with water and can be
           removed easily with a wet cloth.
