Abstract

A current focus among the manufacturers of electrographic printing machines is to improve product reliability. One of the major causes of service maintenance, either scheduled or unscheduled, is drive roll contamination. Drive roll contamination degrades a machine's ability to transport paper. By removing the contaminants from the surface of the roll, the life span of the drive roll is increased and the required mean time between service calls, to repair the machine, is reduced.

LOW COST ROLL CLEANING (Cont'd)

A current focus among the manufacturers of electrographic printing machines is to improve product reliability. One of the major causes of service maintenance, either scheduled or unscheduled, is drive roll contamination. Drive roll contamination degrades a machine's ability to transport paper. By removing the contaminants from the surface of the roll, the life span of the drive roll is increased and the required mean time between service calls, to repair the machine, is reduced.

Proposed is low cost roll cleaning mechanism which is particularly useful on friction retard feeder components, such as a nudger roll or an active retard roll. As illustrated in the figure, an active cleaning mechanism comprising a spring 12 and a brush 14 are mounted to a friction retard paper feeder 10, further comprising a drive roll 18 and an idler roll 16. The spring-loaded cleaner brush removes paper fibers and fillers from the surface of the drive roll 18 and deposits the contaminates into catch tray 20.

The cleaning effectiveness for maximizing particle removal is determined by the bristle material, length, and mounting angle of the brush...
