  • Lubricant coating for laser printer wiper blades
    Patent number: 9284510
    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.
