Abstract: A tray riser is configured for retrofit in a printer feed tray. The riser includes a plate for supporting a stack of sheets in the tray. A stand is integrally formed with a bottom of the plate to position a front edge of the plate higher in elevation than a back edge of the plate. A retention tab is integrally formed with the plate for engaging a pre-existing feature in the tray to retain the riser in the tray.

Abstract: A printer guide clip is configured for retrofit in a paper tray of pre-existing commercially available printer for blocking corner curling of forms transported therethrough. The clip includes first and second side tabs integrally joined together by an arcuate cap extending between the top ends thereof. The first tab is configured for retention inside a pre-existing slot in the paper tray. An inclined ramp extends outwardly from the second tab inside the tray in the vicinity of the form corner for blocking curling thereof during use. The clip is readily attachable to the tray for use with laminated forms, and is easily removable therefrom when no longer needed.

Abstract: A segmented core includes a plurality of integral core segments defined by a respective separation slot in the outer surface thereof. A sheet is wound around the core in a plurality of layers and is slit at the slot to simultaneously wind respective sheet ribbons on the core segments to form individual rolls. The sheet slit is aligned with the core slot which allows the wound rolls to be broken apart at the slots.

Abstract: A security laminate includes a face sheet laminated to a liner by an adhesive. The face sheet includes a removable label. The liner is covered with a release coating behind the label, and has a rim along one edge which is devoid of the release coating except for a security pattern therein.

Abstract: A document feeder includes advance, separation, and transport rollers for driving checks in turn along a feedpath from an input tray containing a stack of the checks A sensor is disposed between the separation and transport rollers for detecting presence of the checks therebetween. A controller is joined to the rollers for controlling speed thereof, and is operatively joined to the sensor for measuring intercheck gaps between the separation and transport rollers. The controller actively adjusts the intercheck gaps by temporarily changing speed of the separation roller at the beginning of the feedpath near the input tray. The intercheck gaps are measured and corrected between the separation and transport rollers for precise control thereof while maximizing throughput.

Abstract: A checkout terminal includes a barcode scanner, input interface, and receipt printer operatively joined to a processor for controlling operation thereof. The processor is programmed for operating the terminal in a transaction mode using the barcode scanner to read a product barcode to conduct a purchase transaction of a product. The processor is also programmed for operating in a store mode using the barcode scanner to read an supervisor barcode on a scancard presented by a supervisor for manually supervising the purchase transaction using the interface.

Abstract: A spinner for a barcode scanner includes mirror facets arranged in a polygon about a rotary axis. A fairing extends radially outwardly from adjacent the facets, and is circumferentially truncated therearound for aerodynamically streamlining the spinner.
