Problems solved by technology

However, no other control of the internal operation of the device is provided, and furthermore, a momentary switch to another process speed cannot be made while the paper is passing through the system, or the paper could tear or wrinkle due to acceleration or deceleration occurring
Therefore, speed changes can only be made after emptying the paper track, after which the process can restart at the changed processing speed, which is time consuming and reduces productivity

Embodiment Construction

[0029] Fig. 1 illustrates a digital image reproducing apparatus 1, different parts of which are separately illustrated in schematic form. The documents to be processed are usually paper, but may include any other type of sheet material for carrying information, such as fee schedules and the like.

[0030] The device has an input unit 22 for supplying paper, which may have several trays containing paper to be processed, and an output unit 23 for receiving processed documents.

[0031] The output unit 23 may include an output tray, or may be a finisher including sorting, stapling and further processing of printed sheets.

[0032] The device has a printing system 26 comprising an electrophotographic processing section known per se, in which a photoconductive medium is charged, exposed via an LED array according to digital image data, and developed with toner, after which the toner image is transferred Printing and fixing onto an image carrier, usually paper, while the paper is t...

Abstract

An image reproduction device for document processing has a nominal processing speed at which it can process sheets continuously at a nominal document quality. However, the image reproduction device is arranged to process sheets at a continuously variable processing speed including the nominal processing speed. The actual processing speed is selected in dependence on operational conditions. In particular, the device is arranged to gradually adjust the processing speed from one processing speed to another processing speed. A control structure is given to select the variable processing speed in dependence on operational conditions, and to operate the image reproduction device at the selected processing speed. In a particular application of the variable speed, a print job may be started at anincreased processing speed and then gradually fall back to the nominal speed, giving a fast start and a shorter processing time for short print jobs.

Description

technical field [0001] The present invention relates to an image reproduction apparatus for document processing, the apparatus comprising: an input unit for supplying paper; a document conveying system for conveying the paper from the input unit to an output unit for receiving a processed document; a paper processing unit , for applying an image pattern to the paper as it is conveyed from the input unit to the output unit at a processing speed; and a control unit configured to process the paper at a nominal processing speed, at a nominal paper distance, and at a nominal document quality , the image reproduction device is configured for continuous operation at a nominal processing speed and for processing paper at a second processing speed higher than the nominal processing speed while processing paper at a nominal paper distance and a nominal document quality . [0002] The invention also relates to a method of controlling an image reproduction device for document processing,...
