Abstract
Abstract A xerographic reproducing machine including a manually operable start switch, a circuit responsive to actuation of the start switch for cycling from a standby condition to an operating condition for performing a process for copying a document, the copying process including machine preparation to a copy ready state and subsequent initiation of the sequential copying steps, a timing circuit for initiating the copying steps after achieving the copy ready state, and a standby circuit for cycling the machine to the standby condition after a predetermined time absent re-actuation of the start switch, the improvement comprising a delay control circuit connected to said timing circuit for delaying initiation of the copying steps after achieving the copy ready state, a switch for selectively activating the delay control switch, and a circuit responsive to activation of the delay control switch for bypassing the standby circuit.

Claim 2
Dependent Claim
135 words
In a xerographic reproducing machine including a manually operable start switch, means responsive to actuation of the start switch for cycling from a standby condition to an operating condition for performing a process for copying a document, the copying process including machine preparation to a copy ready state and subsequent initiation of the sequential copying steps, a timing circuit for initiating the copying steps after achieving the copy ready state, and a standby circuit for cycling the machine to the standby condition after a predetermined time absent re-actuation of the start switch, the improvement comprising: means connected to said timing circuit for delaying initiation of the copying steps after achieving the copy ready state; means for selectively activating said delaying means; and means responsive to activation of the delaying means for bypassing the standby circuit.
Claim 3
Dependent Claim
31 words
The machine of claim 1, wherein said delaying means comprises a timer which when activated interposes a predetermined time between achieving the copy ready state and initiation of the copying steps.
Claim 4
Dependent Claim
43 words
The machine of claim 1, wherein said delaying means comprises a timer which when activated interposes a time period between achieving the copy ready state and initiation of the copying steps and means connected to said timer for selectively varying said time period.
Claim 5
Dependent Claim
29 words
The machine of claim 1, wherein said delaying means initiates the copying steps in response to a command and the machine further includes means for selectively providing said command.
Claim 6
Dependent Claim
14 words
The machine of claim 4, wherein said providing means is a manually operable switch.
Claim 7
Dependent Claim
17 words
The machine of claim 5, wherein said manually operable switch includes a foot pedal for manual actuation.
Claim 8
Dependent Claim
45 words
The machine of claim 1, further including means responsive to actuation of said delaying means for automatically generating two sequential processes for copying a document upon actuation of said start switch, said delaying means controlling initiation of the copying steps of the second sequential process.
Claim 9
Dependent Claim
35 words
The machine of claim 7, wherein said delaying means comprises a timer which when activated interposes a predetermined time between achieving the copy ready state and commencement of the copying steps in said second process.
Claim 10
Dependent Claim
47 words
The machine of claim 8, wherein said delaying means comprises a timer which when activated interposes a time period between achieving the copy ready state and commencement of the copying steps in said second process and means connected to said timer for selectively varying said time period.
Claim 11
Dependent Claim
128 words
In a xerographic reproducing machine which on manual activation cycles from a standby condition to an operating condition in which a copying process generates a copy of a document disposed for copying, and wherein the machine, absent additional manual activation, cycles to the standby condition after completion of the copying process, the improvement comprising: means responsive to said manual activation for causing two sequential coping processes before said machine cycles to said standby condition to permit generation of a copy of two documents successively disposed for copying; means for selectively activating said causing means; and means for controlling the time between said copying processes to permit manual disposition and generation of a copy of the second of said two documents before said machine cycles to said stanby condition.
Claim 12
Dependent Claim
128 words
In a xerographic reproducing machine which on manual activation cycles from a standby condition to an operating condition in which a copying process generates a copy of a document disposed for copying, and wherein the machine, absent additional manual activation, cycles to the standby condition after completion of the copying process, the improvement comprising: means responsive to said manual activation for causing two sequential coping processes before said machine cycles to said standby condition to permit generation of a copy of two documents successively disposed for copying; means for selectively activating said causing means; and means for controlling the time between said copying processes to permit manual disposition and generation of a copy of the second of said two documents before said machine cycles to said stanby condition.
