A powdered chemical mixture for lubricating photoreceptors, wiper blades, doctor blades and slide seals used on dry toner printers, copiers, and facsimile machines. The dry powder comprises a mica group mineral wet-ground to attain cold, dry lubricity, resiliency and particle alignment. The wet-ground mica-group mineral may be coated by calcium stearate to increase lubricity and reduce static electricity from the photoreceptor and blades during operation of the machine. The optimum powder would be comprised of 99% by weight mica-group mineral and 1% by weight calcium stearate. Muscovite and phlogopite are mica-group minerals suggested for use in the lubricating powder. The calcium stearate could also be used with powdered lubricants other than mica to reduce static electricity during operation of the machines.
A method for minimizing wear and tear on the photoreceptor, wiper blade, and doctor blade of printing, copy and facsimile machines, said method comprising lubricating said photoreceptor, wiper blade and doctor blade with a padding powder made by mixing 90% by weight or more of a mica-group mineral and 10% by weight or less of calcium stearate to reduce static electricity created during operation of said machines.
A method as in claims 1 or 3 wherein said mica-group mineral has been wet-ground.
A method for minimizing wear and tear on the photoreceptor, wiper blade, and doctor blade of printing, copy and facsimile machines, said method comprising lubricating said photoreceptor, wiper blade and doctor blade with a padding powder comprising a mica group mineral.
