Abstract: A method of operating a printer produces duplex images in print jobs including ink images to be printed to tabbed, hole-punched, and differently sized media sheets with improved throughput. The method synchronizes a media transport to insert a differently sized media sheet with reference to the type of media sheet, enabling the media sheet to contact a portion of the roller bearing substantially less release agent than the rest of the roller, minimizing release agent transfer to a second side of the media sheet.

Abstract: A system and method are provided for implementing an automated workstation elevation position tracking and control scheme. Software running on the user's computer generates reminders and/or to forces an individual to periodically readjust the height of the workstation in a manner that promotes standing while at work. A current position, and an elapsed time that the workstation has been at the current position, is detected with an objective of providing pre-programmed routine or random automated reminders to a user to change the current position of the workstation from one elevation state to the other. The software tracks the percent of time that a user is standing and optionally compares this with a pre-defined goal. Automatic control via the user workstation, of workstation elevator actuators is provided in a manner that makes it easier, or otherwise unavoidable, for the user to initiate repositioning from a sitting to a standing position.

Abstract: A media feeder system for use with a media cutting system having a cutting table includes an upper out-feed tray and a lower in-feed tray bins are disposed laterally adjacent one side of the cutting system table. A bi-directional media transport system transports media in an in-feed direction from the in-feed tray to the cutting table surface and removes media from the cutting table surface in an out-feed direction from the cutting table surface to the out-feed tray. The media transport system includes a sheet acquisition system having gripping apparatus that adjust for a height of the media held in the bins.

Abstract: According to aspects illustrated herein, a system, a printmaking device, and a method for pre-curling and registering media are provided herein. The system includes a media curler system and a deskew mechanism. The media curler system pre-curls at least one of lead edge and a trail edge of a sheet before delivery to a media hold-down transport. The deskew mechanism is coupled to the media curler system for pivoting the media curler system about a pivot axis to deskew the sheet. The pivot axis extends perpendicular to the media transport path. In operation, as the lead edge enters the pre-curling and registration system, the media curler system pre-curls the sheet towards the media hold-down transport. As the sheet is being pre-curled, the deskew mechanism pivots the media curler system about the pivot axis to correct any skew errors in the sheet.

The roll apparatus is positioned to receive the labels from the adhesive applicator, and the backing media is positioned within the roll apparatus to contact the adhesive-applied side of the labels.

Abstract: Embodiments described herein are directed to a reflex printing system with improved image quality. A media transport moves a media substrate or an intermediate belt along a media path in a process direction past the two or more print heads, which deposit inks onto the media substrate or the intermediate belt. A velocity measuring device directly measures and transmits the speed of the surface of belt or media that is to receive the image to a controller, which sends print commands to the two or more print heads to control the frequency of the printing. The inks deposited on the media substrate or intermediate belt have a color registration of from 10 to 20 microns.
