Abstract

There is a problem of belt debris or belt wear dust contaminating the glass document platen, from wear of the belt surface texture of the rubber frictional belts used for document over-platen transports in copiers or scanners. This problem is reduced by using a more rounded texture belt surface, which has a reduced tendency for projections on the belt surface to fatigue and break off.

There is a problem of belt debris or belt wear dust contaminating the glass document platen, from wear of the belt surface texture of the rubber frictional belts used for document over-platen transports in copiers or scanners. This problem is reduced by using a more rounded texture belt surface, which has a reduced tendency for projections on the belt surface to fatigue and break off.

A textured belt is desired to reduce the surface area contact of the belt with the document glass, to reduce static and friction between the belt and the glass. The belt texture is desirably provided at present by texturing the surface of a mold in which the belt is formed or embossed. It has been attempted to use a sandblasting technique or chemical etching. However, both sand blasting and chemical etching tend to result in sharp peaks of texture on the belt surface, which tend to break off from repeated passes of the belt across the document glass surface and can accumulate as gummy deposits on the glass surface. This a particular problem in Japan, where cleaning of the glass platen is considered to be a proper function only of the tech rep rather than the operators of the machine.

It has been found that a significant improvement is provided by using a glass beaded mandrel for the formation of the document belts. Mold te...
