Abstract
Abstract A programmable controller is used to control the operation of a xerographic reproducing machine adapted to run in a simplex or duplex mode whereby copies are made on either or both sides of web material fed in a single pass and then cut into individual copy sheets. A master program for operating the machine components to produce copies in accordance with the copy run instructions inputted by the machine user is provided. The master program includes a subroutine to place the user's copy run instructions in preselected order irrespective of the order in which the copy run instructions are received, such order being correlated with the order in which the originals are presented for copying. In a second subroutine the controller periodically performs housekeeping chores checking the operational status of the machine.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
91 words
In a reproduction system including an electrostatic type reproduction machine for producing copies from originals, the combination of: control means for programming the reproduction system to produce one or more copy reproduction runs; program storage means for storing the reproduction run program generated by said control means pending use by said reproduction system; and program ordering means for placing the reproduction run program generated by said control means in predetermined order in said program storage means irrespective of the order in which said reproduction runs are programmed into said control means.
Claim 2
Dependent Claim
91 words
In a reproduction system including an electrostatic type reproduction machine for producing copies from originals, the combination of: control means for programming the reproduction system to produce one or more copy reproduction runs; program storage means for storing the reproduction run program generated by said control means pending use by said reproduction system; and program ordering means for placing the reproduction run program generated by said control means in predetermined order in said program storage means irrespective of the order in which said reproduction runs are programmed into said control means.
Claim 3
Dependent Claim
55 words
The reproduction system according to claim 1 including feeding means for bringing said originals in succession into operative relationship with said machine, said program ordering means arranged the reproduction run program generated by said control means so that said reproduction runs correspond with the order in which said originals are presented to said reproduction machine.
Claim 4
Dependent Claim
125 words
In a reproduction system including an electrostatic type reproduction machine for producing copies from originals, the system including means for bringing originals into copying relationship with the machine, the combination of: control means for programming the reproduction system to produce one or more copy runs, each of said copy runs comprising a preset number of copies of predetermined ones of said originals; program storage means for storing the copy runs programmed by said control means pending use by said reproduction system; and program ordering means for placing the copy runs programmed by said control means in order corresponding to the order in which the originals are presented to said machine irrespective of the order in which said copy runs are programmed into said control means.
Claim 5
Dependent Claim
125 words
In a reproduction system including an electrostatic type reproduction machine for producing copies from originals, the system including means for bringing originals into copying relationship with the machine, the combination of: control means for programming the reproduction system to produce one or more copy runs, each of said copy runs comprising a preset number of copies of predetermined ones of said originals; program storage means for storing the copy runs programmed by said control means pending use by said reproduction system; and program ordering means for placing the copy runs programmed by said control means in order corresponding to the order in which the originals are presented to said machine irrespective of the order in which said copy runs are programmed into said control means.
Claim 6
Dependent Claim
117 words
In a reproduction system including an electrostatic type reproduction machine for producing copies from originals, the system having at least two distinct operating modes, the combination of: a control panel for use in programming the reproduction system to produce the copies desired, said control panel including plural manually actuable mode selectors for selecting the system operating mode, said mode selectors being capable of random actuation; program storage means for storing the program generated from said control panel pending use by said reproduction system; and program ordering means for placing the program generated by said control panel in predetermined order for storage in said program storage means irrespective of the order in which said mode selectors are actuated.
Claim 7
Dependent Claim
117 words
In a reproduction system including an electrostatic type reproduction machine for producing copies from originals, the system having at least two distinct operating modes, the combination of: a control panel for use in programming the reproduction system to produce the copies desired, said control panel including plural manually actuable mode selectors for selecting the system operating mode, said mode selectors being capable of random actuation; program storage means for storing the program generated from said control panel pending use by said reproduction system; and program ordering means for placing the program generated by said control panel in predetermined order for storage in said program storage means irrespective of the order in which said mode selectors are actuated.
Claim 8
Dependent Claim
123 words
In a reproduction machine for producing impressions of an original to be reproduced, the reproduction machine having a photosensitive member and a plurality of discrete operating components cooperable with one another and the photosensitive member to electrostatically produce impressions on support material, the improvement comprising: a programmable controller for use in programming the machine to produce the impressions desired, said controller including a master program, a computer, said computer being adapted to calculate in accordance with said master program timing signals for actuating said components to produce the copies programmed, and memory means for storing said timing signals pending use by said controller, said master program including an instruction routine for periodically causing said computer to check the operational status of said machine.
