20100013143 | Method for Dynamically Lifting Elevator Platform of Media Input Tray During Ongoing Media Process - A method for dynamically lifting an elevator includes picking a sheet from a stack to feed to a media process where the stack is on a platform that can be lifted by an elevator, performing the media process, sensing a top of the stack to detect presence or absence of the stack at a media home position, sensing the top of the stack to detect presence or absence of the stack on the platform, sensing the platform to detect its presence or absence at a maximum elevator level, and indexing the stack at least once by lifting the platform through a given distance, during the media process and not during picking a sheet, unless presence of the top of the stack at the media home position is sensed or absence of media sheets on the elevator platform is sensed or presence of the elevator platform at the maximum elevator level is sensed. | 01-21-2010 |
20100032883 | Kiosk-Installable Printer with Duplex Path Utilized to Deliver Printed Media Sheets to Lower Front Exterior of Printer - An image forming device includes an image formation path extending from an entrance end adjacent to a source of supply of media sheets, past an image forming station, to an exit end adjacent to a top collection site adapted to receive media sheets, a duplex path extending from an inlet end adjacent the top collection site to an outlet end adjacent a lower front opening in the device, a media sheet directing mechanism disposed between the exit end of the image formation path, top collection site and inlet end of the duplex path and selectively operable to deliver printed media sheets to the top collection site or the inlet end of the duplex path, and a deflector mechanism between the lower front opening and the outlet end of the duplex path and operable to divert printed media sheets from the duplex path through the lower front opening to exterior of the device. | 02-11-2010 |
20100038846 | Media Handling System for Lowering and Raising Stack Platform Responsive to Moving Bin Between External and Internal Positions - A media handling system for an image forming machine includes a stationary frame, a platform supporting a stack of media sheets thereon, a bin supporting the platform and in turn supported on the stationary frame for undergoing movement relative thereto between a first position in which the bin locates the platform below and aligned with a pick mechanism and movable relative to the bin toward and away from the pick mechanism and a second position in which the bin displaces the platform away from and out of alignment with the pick mechanism, and a motion transmitting assembly coupled between the stationary frame, platform and bin and operable to convert movement of the bin between first and second positions relative to the stationary frame into movement of the platform relative to the bin toward and away from the pick mechanism. | 02-18-2010 |
20100053699 | Method, System and Test Sheet Image Bitmap for Carrying out a Scanner-and-Processor Based Image-to-Paper Registration Setup - A method and system for carrying out an image-to-paper printer registration setup includes: using a printer undergoing registration setup, printing a test pattern on a sheet having reference targets within a printable region of the sheet; using a scanner, scanning the printed sheet to generate an image bitmap of the test pattern-bearing sheet larger than the sheet itself so that the image bitmap contains the sheet edges and measuring in numbers of pixels the distances between the reference targets and/or sheet edges using multiple swaths of the image bitmap itself as the measuring tool; and, using a processor and based on the measured distances, calculating error-associated adjustment values in millimeters to use to correct errors in the registration setup of the image-to-paper in the printer and transferring the error-associated adjustment values to the printer to perform adjustment of its setup actuators. | 03-04-2010 |
20100109230 | Media Sheet Feeding Method for Overcoming at Least One Media Handling Failure Mode - A sheet feeding method includes supporting a media stack on an elevator, initiating operation of a pick roll in conjunction with a top most sheet, sensing whether or not the pick roll is operating in conjunction with the top most sheet, and moving the elevator, in response to the pick roll not operating in conjunction with the top most sheet, to overcome occurrence of a media handling failure mode between the pick roll and the top most sheet. The elevator is lowered, in response to the pick roll rotating but the top most sheet not arriving at a sheet arrival sensor, to increase a normal force imposed on the top most sheet to overcome the occurrence of a ‘fails to feed’ failure mode. The elevator is raised, in response to the pick roll not rotating, to decrease the normal force imposed on the top most sheet to overcome the occurrence of a ‘pick roll stall’ failure mode. | 05-06-2010 |
20100166469 | System and Drive Arrangement for Using Fuser Temperature Cycling to Change Rotational Position of a Fuser Roller Wiper - A system and drive arrangement for using fuser temperature cycling to change rotational position of a fuser roller wiper includes a frame, a hot roll, a fuser roller, and a drive arrangement. The frame of the fuser unit has side panels spaced apart from one another and positioned alongside a media path through the fuser unit. The hot roll on the fuser unit is rotatably mounted to the side panels of the frame and extends between the side panels across the media path. The fuser roller wiper is rotatably mounted between the side panels of the frame and performs a wiping action on the hot roll to remove foreign matter therefrom and supply of lubricant thereto. The drive arrangement is coupled to the fuser roller wiper and is operable in response to decrease in temperature of the fuser unit to rotate the fuser roller wiper. | 07-01-2010 |
20100329766 | DEVICE AND METHOD FOR PRINTING BANNER MEDIA - An apparatus and method for printing banner media utilizing a conventional laser printer wherein no or substantially no modification is required to the paper tray of the laser printer. The apparatus further includes a storage compartment that can be operably coupled with the paper tray. Disposed within the storage compartment is a plurality of rotatably mounted spools having a banner media stored thereon. Additionally, an alternative method of configuring banner media in a conventional paper tray is provided whereby the banner print media is configured in one of a z-fold configuration and a modified z-fold configuration, with the modified z-fold configuration to inhibit creases in the banner print media. | 12-30-2010 |
20110133615 | Electronic Locking System to Secure Consumable Item in an Image Forming Device and a Method Therefor - An electronic locking system to secure consumable items in an image forming device and a method therefore. In one embodiment of the invention, an electronic locking system to secure media sheets includes a media tray to hold media sheets, a tray receiving member for receiving the media tray, and a controller. The tray receiving member includes a drive device and a plunger. The plunger is moved by the drive device between a locked and an unlocked position. The controller is configured to control the drive device to move the plunger to engage a portion of the media tray in the locked position and to move the plunger to disengage from the portion of the media tray in the unlocked position. The electronic locking system, incorporating the controller, provides an effective and efficient way to lock/unlock the media tray and eliminates the use of mechanical keys. | 06-09-2011 |
