Abstract
Abstract Various operating modes of the reproduction machine require the use of machine resources such as an automatic document handler tray, a finisher station tray, a dedicated duplex tray and main and auxiliary paper feed trays. The machine will automatically recover for lost or damaged copy sheets with a minimum amount of operator intervention and loss of copy sheets by efficient use of the machine resources. In particular, job recovery occurs at various levels such as pause in processor operation, point to required duplex tray sheet, and point to set boundary. Various levels of job recovery require use of different resources and some malfunctions imply plural levels of job recovery.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
72 words
In a reproduction machine having resources including a processor, a main tray paper feeder, a recirculating document handler tray, a duplex tray, an output tray and a control, a method of job recovery comprising the steps of detecting malfunctions, determining the resources affected by the malfunction, deciding a recovery procedure to minimize loss of copy sheets related to the resources pointing to an appropriate boundary, recovering from the malfunction and continuing operation.
Claim 2
Dependent Claim
72 words
In a reproduction machine having resources including a processor, a main tray paper feeder, a recirculating document handler tray, a duplex tray, an output tray and a control, a method of job recovery comprising the steps of detecting malfunctions, determining the resources affected by the malfunction, deciding a recovery procedure to minimize loss of copy sheets related to the resources pointing to an appropriate boundary, recovering from the malfunction and continuing operation.
Claim 3
Dependent Claim
19 words
The method of claim 1 wherein certain malfunctions imply other malfunctions including the step of implying predetermined recovery procedures.
Claim 4
Dependent Claim
29 words
The method of claim 1 wherein the step of deciding a recovery procedure includes the step of determining that operation can continue with no alteration of sheets in process.
Claim 5
Dependent Claim
17 words
The method of claim 1 wherein the step of deciding includes the step of aborting the operation.
Claim 6
Dependent Claim
18 words
The method of claim 1 wherein the step of deciding includes the step of replacing sheets in process.
Claim 7
Dependent Claim
14 words
The method of claim 5 including the step of pointing to a sheet boundary.
Claim 8
Dependent Claim
14 words
The method of claim 5 including the step of pointing to a set boundary.
Claim 9
Dependent Claim
16 words
The method of claim 5 including the step of determining the duplex tray is not intact.
Claim 10
Dependent Claim
35 words
The method of claim 5 including the step of determining that the sheets of the duplex tray are misordered and the step of implying the duplex tray is intact and the output tray is misordered.
Claim 11
Dependent Claim
82 words
In a reproduction machine having resources including a processor, a main tray paper feeder, a recirculating document handler tray, a duplex tray, an output tray and a control, a hierarchy method of job recovery including a processor pause, a duplex misfeed, a processor paper jam, and a processor multifeed, comprising the steps of detecting malfunctions, determining the resources affected by the malfunction, deciding upon a recovery procedure to enhance the use of the resources, and recovering from the malfunction and continuing operation.
Claim 12
Dependent Claim
82 words
