Abstract

In a copier machine with the job-interrupt feature, the machine is provided with a degree of artificial intelligence by restoring the parameters of the interrupted job (job 1) upon the completion of the interrupting job (job 2). This involves the provision of a time delay between the end of job 2 and the automatic restoration of the job 1 parameters to allow enough time for an operator to continue job 2 if more originals need to be fed. Consequently, a relatively long time delay between feeding job 2 sheets is provided for manual jobs which may involve the rotation of books or the swapping of manual originals, while a relatively short time delay is provided for the continuation of job 2 where job 2 uses the automatic document feed (ADF) or semiautomatic document feed (SADF).

Automatic Restoration of Interrupted Job

In a copier machine with the job-interrupt feature, the machine is provided with a degree of artificial intelligence by restoring the parameters of the interrupted job (job 1) upon the completion of the interrupting job (job 2). This involves the provision of a time delay between the end of job 2 and the automatic restoration of the job 1 parameters to allow enough time for an operator to continue job 2 if more originals need to be fed. Consequently, a relatively long time delay between feeding job 2 sheets is provided for manual jobs which may involve the rotation of books or the swapping of manual originals, while a relatively short time delay is provided for the continuation of job 2 where job 2 uses the automatic document feed (ADF) or semiautomatic document feed (SADF).

Fig. 1 shows a document feed unit wherein a stack of documents can be placed on ADF tray 10 and fed automatically one at a time onto a document glass 31. Similarly, sheets can be fed one at a time to glass 31 through SADF tray 22 by manually placing a next sheet on tray 22 after the preceding sheet is automatically moved to glass 31.

This configuration enables the user to interrupt a first job in process on the automatic document feed with a second job which can be processed through the semiautomatic document feed. Conversely, an SADF job may be interrupted by an ADF job.

When using the job-interrupt feature, an interrupt button is pushed in order to suspend job 1. Next, the operator will key in the parameters for job 2, that is, the number of copies to be made,...
