Abstract

In certain printers utilizing photoconductor surfaces, cleaner brushes having soft fibers sheared to a uniform length are utilized to remove toner from the photoconductor surface. In the event that some of the fibers are of excessive length, the longer fibers strike the photoconductor surface during cleaning with an energy level which causes the toner to melt and adhere to the photoconductor. This causes print problems and premature end of life of the photoconductor. (Image Omitted) Accordingly, a technique is described for improving the shearing and conditioning of cleaning brush fibers to ensure that brushes are produced having uniform fiber length without bird-fiber tips.
