Abstract

Abstract In a stand-alone or add-on sorter for a reproduction machine, the sorter has access to its own collection of diagnostic programs under control of a single push button carried on the sorter housing. A lamp associated with the push button is used to indicate, as by its frequency of pulsing, the diagnostic state of the machine, and a manually-operable switch is used to move the sorter between its normal and diagnostic modes. When in its stand-alone configuration, the number of successive sorting operations to be carried out by the sorter, before returning to its home position, is controlled by the number of successive operations of the push button, with the switch being in its normal position.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 152 words
In a reproduction machine for producing impressions of an original, the reproduction machine having a photosensitive member and a plurality of discrete operating components cooperable with one another and the photosensitive member to produce the impressions on copy paper, and including an accessory for operating on the copy sheet, the accessory comprising a controller storing several diagnostic procedures, the controller including a microprocessor and a memory, a first switch connected to the microprocessor, the first switch settable into either a normal or diagnostic position, a second switch connected to the microprocessor, the second switch controlling operation of the accessory, and means responsive to the first switch in the diagnostic position for causing selective operation of the second switch to make diagnostic procedures available in sequence, a given procedure being initiated automatically upon lapse of a given time period after selective operation of the second switch without further actuation of the second switch.
Claim 2
Dependent Claim 152 words
In a reproduction machine for producing impressions of an original, the reproduction machine having a photosensitive member and a plurality of discrete operating components cooperable with one another and the photosensitive member to produce the impressions on copy paper, and including an accessory for operating on the copy sheet, the accessory comprising a controller storing several diagnostic procedures, the controller including a microprocessor and a memory, a first switch connected to the microprocessor, the first switch settable into either a normal or diagnostic position, a second switch connected to the microprocessor, the second switch controlling operation of the accessory, and means responsive to the first switch in the diagnostic position for causing selective operation of the second switch to make diagnostic procedures available in sequence, a given procedure being initiated automatically upon lapse of a given time period after selective operation of the second switch without further actuation of the second switch.
Claim 3
Dependent Claim 43 words
An accessory as claimed in claim 1, in which the accessory includes a mode indicator connector to the microprocessor for indicating when the necessary is in its diagnostic mode, and for indicating when a selected operation of the second switch has been validated.
Claim 4
Dependent Claim 29 words
An accessory as claimed in claim 1, in which the mode indicator is a lamp for emitting pulsating or continuous light to indicate different diagnostic states of the accessory.
Claim 5
Dependent Claim 48 words
An accessory as claimed in claim 1, in which the lamp includes means to pulse at one frequency to indicate when the accessory is in its diagnostic mode, and means to pulse at another frequency when a choice of a diagnostic procedure has been accepted by the accessory.
Claim 6
Dependent Claim 61 words
An accessory as claimed in claim 1, when used as a sorter for a succession of copy sheets, in which, when the first switch is in its normal position, the number of successive sorting operations to be carried out by the sorter before it returns to its start position is dictated by the number of successive actuations to the second switch.
