Abstract
A printer dynamic job recovery operation in an electronic reprographic system includes automatic detection of a printed sheet having an image thereon with a relative loss of integrity. Specified sheets are automatically purged to a specified location in response to such detection. The purging can begin at the first detected sheet or up to three sheets in advance of the detected sheet. Job recovery for job completion can be initiated immediately without cycling down the printer.
Claims12
A method for dynamic job recovery in an electronic reprographic system comprising the steps of:
- automatically detecting the presence of a printed sheet having an image thereon with a relative loss of integrity;
- automatically purging specified sheets to a specified location upon said detection, said purging step including initiating purging at a specific sheet with respect to the first sheet detected having an image thereon with loss of integrity and purging said specific sheet and all sheets in a paper path trailing said specific sheet, regardless of whether the purged sheets have an image thereon with loss of integrity;
- awaiting delivery of said purged sheets at said specified location;
- and
- initiating dynamic job recovery as soon as all the specified sheets have been delivered, said steps being performed without cycling down of the electronic reprographic system and without operator intervention, said dynamic job recovery including assessing job completion progress of all partially completed jobs and starting recovery job scheduling without specific direction.

An apparatus for dynamic job recovery in an electronic reprographic system comprising:
- detection means for automatically detecting the presence of a printed sheet having an image thereon with a relative loss of integrity;
- purge means for automatically purging specified sheets to a specified location upon said detection, said purge means initiating purging at a specific sheet with respect to the first sheet detected having an image thereon with loss of integrity and purging said specific sheet and all sheets in a paper path trailing said specific sheet, regardless of whether the purged sheets have an image thereon with loss of integrity;
- awaiting means for awaiting delivery of said purged sheets at said specific location;
- and
- recovery means for initiating dynamic job recovery as soon as all the specified sheets have been delivered, said recovery means operating without cycling down of the electronic reprographic system and without operator intervention, said dynamic job recovery including assessing job completion progress of all partially completed jobs and starting recovery job scheduling without specific direction.

A method for dynamic job recovery in an electronic reprographic system comprising the steps of:
- automatically detecting the presence of a printed sheet having an image thereon with a relative loss of integrity;
- automatically purging specified sheets to a specified location upon said detection, said purging step initiating purging at the first sheet detected having an image thereon with a loss of integrity and purging said first sheet and all sheets in a paper path trailing said first sheet, regardless of whether the trailing sheets have an image thereon with loss of integrity;
- and
- immediately initiating dynamic job recovery upon detection of a sheet having an image thereon with a relative loss of integrity, said steps being performed without cycling down of the electronic reprographic system and without operator intervention, said dynamic job recovery including assessing job completion progress of all partially completed jobs and starting recovery job scheduling without specific direction.
