ABSTRACT:
FIELD OF THE INVENTION
This invention relates to printers and copiers and specifically to the automatic disposal of unwanted documents generated by such paper output devices.
BACKGROUND OF THE INVENTION
A variety of printers and copiers are known which have multiple output bins for sorting and collating the paper output generated by these devices. As happens on occasion, a job must be cancelled. Prior art devices require the user to manually remove any partial output of a canceled job from the output bins, and place that job in a waste receptacle, which may or may not include shredding the job.
U.S. Pat. No. 4,083,550, for Multiple copy sorting apparatus, to Pal, granted Apr. 11, 1978, describes an apparatus for sorting multiple copy jobs.
U.S. Pat. No. 4,330,200, for Copying machine with collating apparatus, to Kikuchi et al., granted May 18, 1982 describes a collator for collation of print jobs, one page at a time, which reverts to a normal operation mode following a predetermined time-out.
U.S. Pat. No. 4,696,466, for Sorter for electrophotographic copying machine, to Yamasaki et al., granted Sep. 29, 1987, describes a sensor-equipped sorting device for use with a photocopy machine, wherein an interruption in a copy job rearranges output to specific bins, allowing the original job to be completed without disrupting the original sorting process.
U.S. Pat. No. 5,098,074, for Finishing apparatus, to Mandel et al., granted Mar. 24, 1992, describes a copy machine having an automatic stapler associated therewith.
U.S. Pat. No. 5,104,106, for Sheet sorter with stapler to Shido et al., granted Apr. 14, 1992, describes another copy machine having a stapler associated with a collator.
U.S. Pat. No. 5,328,169 for Mailbox or sorter bin use sensing system, to Mandel, granted Jul. 12, 1994, describes a sorter wherein empty bins are identified by an optical sensor.
None of the known prior art devices has any means for automatically disposing of the paper output from an unwanted print or copy job.
SUMMARY OF THE INVENTION
A system for automatic disposal of an unwanted output includes a print engine for generating a print job having an output; a finishing device connected to said print engine for finishing said print job, wherein said finishing device includes: an intermediate bin for receiving said output from said print engine, and for holding said output until said print job is complete; a waste bin for selectively receiving a cancelled print job; and at least one output bin for receiving a completed print job.
An object of the invention is to provide a system for automatically disposing of unwanted paper output from a print or copy job.
Another object of the invention is to provide a system for automatically shredding such unwanted paper output.
These and other object of the invention will become more fully apparent as the description which follows is read in conjunction with the drawing.
