Abstract: A media diverter system for an imaging device including a single motor coupled to one of a plurality of diverter assemblies for sequentially directing media sheets from an input path to one of a plurality of output destinations. Each diverter assembly includes a gate moveable between a first and a second position for opening a path between an input and a first and a second output, respectively, a pivot arm coupled to the gate, and a drive gear providing a lobe having up and down camming surfaces on which the pivot arm travels. The single drive motor rotatably is coupled to the drive gears, and, as the drive motor is driven, the drive gears synchronously rotate and corresponding gates are moved to one of a first and a second position for providing a media path from an input of the system to a selected one of the output destinations.

Abstract: A friction backup roller assembly for a peripheral device, comprising an auto-compensating mechanism having a pick tire at one end, a media tray disposed adjacent to the auto-compensating mechanism, a backup roller extending through an aperture in the media tray, the backup roller having a tire, the auto-compensating mechanism pivotally positioned for engagement and disengagement of the pick tire with the backup roller, and a biasing element acting on the backup roller.

Abstract: A media pick assembly has a media tray for retaining a stack of media in a peripheral device, an auto-compensating mechanism disposed adjacent to the media tray, the auto-compensating mechanism movable through an operating range including a starting angular position and an ending angular position, and a media biasing member engaging the auto-compensating mechanism and providing a discontinuous force on the auto-compensating mechanism through the operating range.

Abstract: A removable duplex unit for an image forming peripheral having a simplex media feedpath and a reversible roller for moving media in a first direction through the peripheral and in a second direction through the duplex unit, includes an auxiliary housing adapted to be removably connected to the image forming peripheral, the auxiliary housing having therein a curved duplex media feedpath of a preselected length extending through the auxiliary housing in feeding communication with the reversible roller in the simplex media feedpath wherein the duplex feedpath in the auxiliary housing is passive and does not provide energy to media passing through the duplex media feedpath.

Abstract: Drag from media sensor (80) of a printer is eliminated by it being pivoted through a slip connection off of pivoted media feed system (19) to briefly contact papers. The pivoted media feed is then moved in reverse a limited amount at which a rotatably biased member (94) moves ledge (94a) of the member to face abutment surface (92a) of the media sensor. Media feed system 19 is then moved back to drive media while the media sensor is blocked from movement and the slip connection simply slips. After the media is fed, the media feed system is moved away a longer amount while the media sensor is blocked against for the same movement by an abutment (110) in the printer. The media feed system after the longer movement moves a lever (94f) of the biased member and rotates the ledge to free the media sensor to again move to the media.

Abstract: An imaging apparatus includes a printing mechanism having a media path. A print media source is provided for supplying a sheet of print media to the printing mechanism. A drive unit is provided, with a drive shaft coupled to the drive unit. A media sensor device is mounted to the drive shaft, wherein as the drive shaft is rotated in a first direction the media sensor device is moved from a first position that is out of the media path to a second position that is in the media path for sensing the sheet of print media. As the drive shaft is rotated in a second direction opposite to the first direction the media sensor device is moved from the second position that is in the media path for sensing the sheet of print media to the first position that is out of the media path.

Abstract: A speed mode for a printer (1) which has a pivotally mounted autocompensating system (19) mounted at an intermediate position in paper guide (17). That system (19) is driven by a motor (40) through a slip drive (70, 72, 74). The motor also drives paper feed system (15). When the motor turns in a direction to feed by system (15), the intermediate system is moved away from the paper guide. In basic operation, when a sheet (5) reaches a position to be fed by the intermediate system, the motor is reversed, and the intermediate system pivots against the paper for moving it further through the paper guide. In the speed mode the intermediate system is not employed and all of the feed is by the system at the tray. Since this will not feed shorter sheets, preferably the speed mode must be positively invoked, as by operator input or definitive information in the header of a print job.
