Abstract: A duplex sheet printer comprising a first and second sheet quality detection device for determining a suitability of a sheet for printing. The first sheet quality detection device applies a first sheet rejection threshold to which sensed sheets are compared, while the second sheet quality detection device applies a second sheet rejection threshold different from the first. The controller designates sheets in the printing system to be sensed by one of the sheet quality detection devices in accordance with the sheet's media type or the sheet being on a simplex or duplex pass. Different rejection criteria are thus applied to the sheets without adjustment of a sheet quality detection device, resulting in high speed printing.

Abstract: In a method for high speed printing of web-based media, a medium is pulled along a media transport path to a pulling transport mechanism. The orientation of the medium with respect to the media transport path is sensed and this orientation is compared to a reference orientation to detect an orientation error. If an orientation error is detected, one or more of the following steps is performed: adjusting a print job for an image to be printed on the web medium; adjusting the transport speed; emitting a communication signal; and stopping the pulling transport mechanism and the image forming unit. It is the insight of the inventor that productivity may be increased by allowing a “tight winding” printing system to start printing at relatively high speed and reduce this speed only when significantly large deviations in the orientation of the web are detected.
