Abstract

The importance of blade cleaning systems in the xerographic process is well known. A basic problem with all blade cleaning systems, however, is that contaminates wedge themselves under the tip of the blade and thus create a cleaning streak.

The importance of blade cleaning systems in the xerographic process is well known. A basic problem with all blade cleaning systems, however, is that contaminates wedge themselves under the tip of the blade and thus create a cleaning streak. This is true of both dry xerographic and liquid ink systems. A method of removing these contaminates is described herein.

When photoreceptor 5 stops at the end of a print cycle, cleaning blade 6 is lifted and the contaminates both on the tip 7 of blade 6 and on photoreceptor 5 are removed. A device for removing both sets of contaminates consists of a cleaning pad 9 mounted on a two~-positiontoggle pad holder 10 that is positioned closed to the blade tip 7. When photoreceptor 5 has stopped, the blade is retracted clockwise striking the rear of pad holder 10 turning it counterclockwise into its out position

(the position shown in dotted 1ines)~ This places pad 9 under the blade tip 7~ The blade 6 is now driven counterclockwise back to the photoreceptor 5~ The two~ position toggle pad holder 10 holds pad 9 such that blade 6 must strike the pad 9 as the blade returns toward photoreceptor 5~ This allows pad 9 to interfere with the tip of blade 6 and...
