Apparatuses include, among other components, a pair of opposing drive rollers, a pair of opposing idle rollers, and a rotatable support operatively connected to the axles of the idle rollers. Axles of the drive rollers and the idle rollers are positioned along a circle. The axles of the drive rollers and the idle rollers alternate along the circle. Also, rotation of the rotatable support moves the idle rollers along the circle until the idle rollers contact the drive rollers. Each of the idle rollers is positioned by the rotatable support to only contact a single drive roller at a time.

Printing devices herein comprise an internal power supply within the body of the printing devices. Also, a processor and printing components are within the body and connected to the internal power supply. A user interface is external to the body and is connected to the processor and the internal power supply. The user interface has a universal serial bus (USB) connection. A USB hub structure is within the body and is connected to the processor, the internal power supply, and the user interface. The USB hub structure includes an integrated circuit (IC), a power connector connected to the internal power supply, and a plurality of USB connectors connected to the IC. The USB connectors can extend through the body and one of the USB connectors connects the USB connection of the user interface to the processor and the internal power supply.

Printer USB hub for peripheral connections

Printing devices include a printer power supply, a printer processor connected to the printer power supply, printing components connected to the printer power supply and the printer processor, and a tablet interface device connected to the printer processor and the printer power supply. The tablet interface device includes a tablet processor, a USB connection electrically connected to the tablet processor and the printer power supply, and a touchscreen surface electrically connected to the tablet processor. The tablet processor is adapted to operate independently of the printer processor.

A method for feeding uneven media from a high capacity feeder includes rotating the pages in a stack 180&#xb0; every 100-250 pages. This is only done with non-flat pages, such as, envelopes, pages with labels thereon, etc., which create tilted stacks and limit the number of pages that can be placed in the high capacity feeder. Rotating the pages 180&#xb0; distributes the uneven build-up of the pages and creates a relatively flat stack, allowing the high capacity feeder to be filled to capacity. A camera or sensor placed in the high capacity feeder will detect the orientation of the stack on the fly so the image can be rotated accordingly.

A method and system for enabling an image production device to copy pages of a book includes determining an orientation of a first scanned page of a book, and modifying an orientation of a second scanned page of the book based on the orientation of the first scanned page. The second scanned page is in sequence relative to the first scanned page.

Automatic image inverting for book copying

A method to detect edges based on chrominance information alone or in combination with gray level values includes comparing chrominance values to a registration parameter based on chromacity measurements of a backing. To calibrate a system, a small scan obtains sample image data for the backing in the document feeder. Using the sampled image data, average chrominance values for the backing are determined. Based on the averages, a channel having a low chrominance contribution is selected as the registration channel. A registration parameter is calculated for automatic registration of documents based on the average chrominance and chrominance deviation for the registration channel.
