US 9,284,510 B2 · Lubricant coating for laser printer wiper blades

Abstract

A lubricant coating for laser printer wiper blades is a solution applied to a laser printer wiper blade before install that reduces friction between the wiper blade and the photoconductor drum of a laser printer in order to reduce wear, prevent damage and increase life of the wiper blade and photoconductor drum. A leveling and wetting agent ensures uniform application and reduces coating defects. An anti-wear agent reduces friction and acts as an electrical insulator. A friction reducing agent also reduces friction and acts as an electrical insulator. An evaporation promoting agent aids in evaporation of unnecessary material after application to a wiper blade. A coating enhancing agent increases the hardness of the coating and provides assistance in adherence of the solution to the wiper blade. Deionized water acts as a carrier. The solution is mixed in a high shear mixture.

Dependent claims

A method for reducing friction between a wiper blade and a photoconductor drum in a laser printer, said method comprising the steps of:

preparing a lubricant coating containing 5-15 wt % of a level and wetting agent, 5-10 wt % of an anti-wear agent, 7-30 wt % of a friction reducing agent, up to 6 wt % of an evaporating promoting agent, 2-15 wt % of a coating enhancing agent;
and 50-80 wt % of deionized water as a carrier;
applying said lubricant coating to said wiper blade so that said lubricant coating coats all portions of said wiper blade that come into contact with the photoconductor drum;
and
heating said lubricant coating and said wiper blade in an oven.
