Cleaning Procedure for Overcoated Photoconductor Drum or the Like

Residue left on the surface of a photoconductive drum after a cleaning process is removed by the additional step of dusting the drum surface with more toner which is then removed by wiping.

Prior cleaning procedures for photoconductor (PC) drums of copiers include the steps of dry-wiping the drum surface with a flannel drum cloth or the like, inspecting the drum surface for toner build-up, and applying a cleaning solution such as isopropyl alcohol to clean the entire PC surface and especially those areas with toner build-up not removed by the dry wiping. The drum surface is then again dry-wiped with the drum cloth. It is believed that some of the cleaning materials tend to leach from the drum surface after an alcohol cleaning and further tend to plasticize toner and cause it to adhere to the surface as well as to cause copier contamination problems.

According to the present process, the drum surface is dusted with additional copier toner after alcohol cleaning, and then dry-wiped with a flannel drum cloth or the like. The additional toner-dusting step is believed to function as a blotter for the leached or residual elements that may cause toner plasticizing and further facilitates complete removal through the final wiping step.
