Abstract

This article relates to a copier machine with a document-feeding device, the capability of copying on both sides of copy paper (duplex function), and the capability of interrupting job one in process to run job two. When job one is using the duplex function, certain copies may be present in the copier with only a side one printed thereon at the time of interruption. This article provides a special capability to the machine for enabling the operator to choose whether to allow the interrupt immediately and proceed to job two, precluding use of the duplex function to job two, or to delay the interrupt and continue job one until side one copies have received a side two and have been removed from the machine.

Duplex Job Interrupt

This article relates to a copier machine with a document-feeding device, the capability of copying on both sides of copy paper (duplex function), and the capability of interrupting job one in process to run job two. When job one is using the duplex function, certain copies may be present in the copier with only a side one printed thereon at the time of interruption. This article provides a special capability to the machine for enabling the operator to choose whether to allow the interrupt immediately and proceed to job two, precluding use of the duplex function to job two, or to delay the interrupt and continue job one until side one copies have received a side two and have been removed from the machine.

The figure shows a copier machine 10 with a semiautomatic document feed (SADF) 11 for feeding original documents to a document glass. Copy paper is fed from either bin 12 or bin 13 along a paper path 14 to receive an image of the original at transfer station 15. If the duplex function is in use, the copy bearing the side one image is transported to duplex bin 16 where it is held until the original document for side two is fed to the document glass. At this time, the copy sheets are fed out of duplex bin 16 back into paper path 14 to receive the side two image at transfer station 15.

If the interrupt button 17 is pushed while side one copies are being made, the duplex bin 16 will contain copy sheets from job one, as described above. If the control unit for copier 10 allows the interrupt...
