Abstract
Abstract A multitask button, cascade illumination control panel is provided. In one embodiment, successive keying of a single reduction button sequences the system to a 98% reduction, 76% reduction, and 65% reduction, respectively, back to 1-1 reduction. The stepping of the illumination lamps indicating each reduction mode occurs immediately. However, there is a deferred movement of the lens. In other words, there will be delayed response to offset any needless dithering of the machine before the appropriate lens movement is made.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
125 words
In a reproduction machine including an operator console having a number of selector switches for performing a plurality of modes of machine operations, the method of operating the reproduction machine including the steps of initially setting up operation of the machine in a first mode by activating one of the selector switches, selectively activating at least one of the selector switches to change the modes of operation of the machine to a second mode, providing an immediate indication of the selected second mode, and momentarily delaying the initiation of the change in operation of the reproduction machine to the second mode in response to the activation of said one of the selector switches, operating the machine in the second mode after a given time delay.
Claim 2
Dependent Claim
125 words
In a reproduction machine including an operator console having a number of selector switches for performing a plurality of modes of machine operations, the method of operating the reproduction machine including the steps of initially setting up operation of the machine in a first mode by activating one of the selector switches, selectively activating at least one of the selector switches to change the modes of operation of the machine to a second mode, providing an immediate indication of the selected second mode, and momentarily delaying the initiation of the change in operation of the reproduction machine to the second mode in response to the activation of said one of the selector switches, operating the machine in the second mode after a given time delay.
Claim 3
Dependent Claim
35 words
The method of claim 1 including the steps of again activating said said one of the selector switches and providing an immediate indication of a mode of operation different from said second mode of operation.
Claim 4
Dependent Claim
43 words
The method of claim 2 including the step of momentarily delaying the initiation of said mode different from said second mode of operation and the step of completing thechange to said mode different from said second mode of operation after the momentary delay.
Claim 5
Dependent Claim
72 words
In a reproduction machine including an operator console having a predetermined number of machine operation selectors, the combination of first means to activate a first machine operation, means to provide an immediate indication of the first operation selected, said first means adapted for activating a second machine operation, means to provide an immediate indication of the second operation selected, and means to inhibit any machine operation for a predetermined period of time.
Claim 6
Dependent Claim
72 words
In a reproduction machine including an operator console having a predetermined number of machine operation selectors, the combination of first means to activate a first machine operation, means to provide an immediate indication of the first operation selected, said first means adapted for activating a second machine operation, means to provide an immediate indication of the second operation selected, and means to inhibit any machine operation for a predetermined period of time.
Claim 7
Dependent Claim
33 words
The machine of claim 4 including the means to change the machine operation from the first to the second operation in response to the first means to activate after a predetermined time period.
Claim 8
Dependent Claim
91 words
In a reproduction machine for producing impressions of an original, the reproduction machine having a photosensitive member, a plurality of discrete operating components cooperable with one another and the photosensitive member to electrically produce the impressions on support material, and an operator console having a number of machine operation selectors, a method of operation comprising the steps of: sequentially activating an operation selector providing an indication of a different mode of operation for each sequenital activation and changing the mode of operation to the particular operation selected for a particular activation.
Claim 9
Dependent Claim
91 words
In a reproduction machine for producing impressions of an original, the reproduction machine having a photosensitive member, a plurality of discrete operating components cooperable with one another and the photosensitive member to electrically produce the impressions on support material, and an operator console having a number of machine operation selectors, a method of operation comprising the steps of: sequentially activating an operation selector providing an indication of a different mode of operation for each sequenital activation and changing the mode of operation to the particular operation selected for a particular activation.
Claim 10
Dependent Claim
17 words
The method of claim 6 including the step of temporarily delaying the change to the particular operation.
