An improved fuser cleaning purge cycle system of cleaning imaging material from a fuser (particularly, a fuser roll) of a copy reproducing apparatus after an inadvertent interruption of the operation of the apparatus, such as by a paper jam, in which the fuser was potentially contaminated with imaging material from a copy sheet being fused, wherein the reproducing apparatus has an alternative duplex copying path; comprising, automatically, sequentially feeding a preset limited number of preexisting conventional clean copy sheets in the copy reproducing apparatus through the fuser to function as fuser cleaning sheets to remove the potentially contaminating imaging material, then feeding the same fuser cleaning sheets through the alternative duplex copying path back to and through the fuser a second time, with sheet inversion, so that they are inverted before feeding through the fuser the second time, and then purging these fuser cleaning sheets. The fuser cleaning cycle may be automatically initiated in response to sensing that a copy sheet was stopped in the fuser during the interruption of the operation of the reproducing apparatus. Preferably, the preset limited number of sheets used is four or less, yet, preferably, every area of the circumference of a fuser roll is contacted by at least one side of one fuser cleaning sheet a minimum of four times during this fuser cleaning cycle.

Fuser clean-up purge sheets system for duplex reproduction apparatus

A touch sensitive user interface of the type having a display screen for displaying an image; control logic responsive to the touch sensitive user interface for determining the contact position of a probe, such as a finger, thereon; a display menu of operating features, represented by a plurality of images on the display screen, so that a user may make touch selections on the images corresponding to operating features desired; a system controller for identifying a contact zone of a predetermined size with respect to the display screen, the control logic actuating the feature within the system represented by a displayed image in response to user touch within a corresponding contact zone, the system controller enlarging the contact zone of a selected feature upon selection thereof, to a size accommodating a probe tip, without overlapping on adjacent areas and upon completion of option selection, returning the expanded contact areas to said predetermined size.
