摘要： A high-speed printer is provided. The printer includes a media assembly for supporting a media roll that supplies the sheet of media and also for controlling a flow rate of the sheet of media through the printer. The sheet of media is received by the feedback control system, which is used to detect a slack position of the sheet of media. The slack position is used by the media assembly to determine a flow rate of the sheet of media through the printer. In addition, the printer also includes a roller system for receiving the sheet of material from the feedback control system and to feed the sheet of media to a print carriage.

摘要： The present invention provides a multi-function device having a housing, a printer module and a scan module. The housing having a plurality of pivotable panels, wherein the pivotable panels are collapsible on the housing to conform with its surfaces thereon. The printer module has a printer head assembly and a multiple sheet feeder disposed within the housing, the multiple sheet feeder having a first paper guide, a feeder assembly and a second paper guide forming a print path, the printer head assembly is mounted along the print path between the first and the second paper guide, wherein a void to the printer module is defined within the housing between the printer head assembly and the first paper guide. The scan module is collapsibly mounted on the housing, the scan module having a scan bar coupling with a multiple original feeder, wherein the scan module is adapted to submerge within the void when it is at a collapsed configuration, and when it is at a lifted configuration, the scan module forms a scan path. The print path is separated from the scan path. A roller assembly is also provided herein.

摘要： An assembly for feeding media associated with a printer or other media manipulating device includes a feed roller and first and second roller support members that rotatably mount first and second pinch rollers, respectively. The pinch rollers apply pressure to media on the feed roller at spaced pinch locations to increase the contact area between the media and the feed roller. One of the roller support members is movable with respect to the other of the roller support members to vary the distance between the first and second pinch locations and stretch the media on the feed roller during media loading.
