Abstract

A need for a cleaning blade holder that offers a quick, easy assembly or blade change over by the field technical representative has existed for some time. Most cleaning blades are sandwiched between two pieces of metal, aligned and then tightened by several screws. This type of blade holder has a tendency to distort the blade's cleaning edge, resulting in a poor contact with the photoreceptor, thus, creating toner streaks and premature blade wear.

SPRING LOADED BLADE HOLDER(Cont'd)

A need for a cleaning blade holder that offers a quick, easy assembly or blade change over by the field technical representative has existed for some time. Most cleaning blades are sandwiched between two pieces of metal, aligned and then tightened by several screws. This type of blade holder has a tendency to distort the blade's cleaning edge, resulting in a poor contact with the photoreceptor, thus, creating toner streaks and premature blade wear.

In the figure, the present invention is very similar to a proven heavy duty spring loaded holder that has been used for many year to hold stationary paper and other objects. This unique design consists of only three basic parts: two steel jaw-like clamps 4 held together by a single split spring steel tube 6. The cleaning blade 2 is held in this blade holder when force is not applied to the handles 8, as shown. When the handles 8 have a force applied (not shown) the handles are squeezed together, releasing the blade 2 from the holder 10.

This blade holder can be made in sections or as one piece. This configuration provides a strong blade holder for quick, easy assembly of a ridged or flexible cleaning blade.
