A printing system for printing on sheets of media having a non-uniform thickness profile. A user interface is controlled to instruct the operator to load a media tray with a stack of media having a specified pattern of media orientations. A media transport system picks sequential sheets of media from the media tray. A front end supplies sequential image data having orientations in accordance with the specified pattern of media orientations. A printing module sequentially prints the supplied image data on the sheets of media in accordance with the specified pattern of media orientations.

A method for feeding uneven media from a high capacity feeder includes rotating the pages in a stack 180° 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° 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 medium conveying apparatus includes a conveyance roller to convey a medium, a motor to drive the conveyance roller, a signal generator to output a pulse signal, a pulse width of which changes according to a rotation speed of the motor, and a processor to rotate the conveyance roller by controlling the motor, and detect a fluctuation of the pulse width caused by a load fluctuation when the conveyance roller conveys a medium to determine a thickness of the medium according to the pulse width.

A sheet feeding device includes a sheet loader, a sheet feeder, and an end fence. The sheet loader is configured to load a sheet bundle including sheets. The sheet feeder is configured to feed an uppermost sheet of the sheet bundle loaded on the sheet loader. The end fence is disposed movable in a sheet feeding direction of the uppermost sheet and is configured to contact a trailing end of the sheet bundle in the sheet feeding direction to regulate a position of the trailing end of the sheet bundle. The end fence includes an elastic body configured to contact the trailing end of the sheet bundle at a portion other than at least an upper portion of the end fence.

A medium conveying apparatus for conveying media in a conveying direction includes: a medium container on which the media are stacked; and a medium separator that abuts an uppermost medium of the media stacked on the medium container and separates the uppermost medium from the media stacked on the medium container. The medium container includes: a medium support that abuts a lowermost medium of the media stacked on the medium container and supports the stacked media; and a tilting mechanism that tilts the medium support relative to a horizontal plane at a tilt angle according to a weight of the media stacked on the medium container.

A paper sheet handling machine (for example, a banknote handling machine (10)) includes: a storage unit (for example, an escrow unit (20), banknote storages (30), a banknote storage cassette (40)) configured to store a paper sheet transported from a transport unit (16); and a shifting unit (19) provided in the transport unit (16) and configured to shift the paper sheet transported by the transport unit (16), in a width direction orthogonal to a direction in which the paper sheet is transported, according to a position, in the width direction, of a specific member (for example, a tape (136) in the escrow unit (20), a pair of feed rollers of a banknote feeding mechanism (32, 42) provided in the banknote storages (30), a banknote storage cassette (40)) in the storage unit.
