  • Patent number: 9132672
    Abstract: Methods and devices determine the media properties of a sheet of media exiting a printing device. The methods and devices apply the media properties to a predetermined velocity equation to calculate a corresponding sheet exit velocity for the sheet of media that will optimize stack quality in a particular output tray. Then, the methods and devices change process controls sheet movement elements within a media path of the printing device to cause the sheet of media to exit the printing device at the sheet exit velocity.

  • Patent number: 9053413
    Abstract: Methods and systems print markings on a web of media using a printer to produce a printed roll of media. During the printing, the printer automatically analyzes the internal printer conditions, and automatically identifies printing errors based on the internal printer conditions during the printing. Further, such methods and systems automatically record the printing errors in an error log file using a computerized device that is operatively connected to the printer and store the error log file in a network storage element within a computerized network. Also, such methods and systems transmit the error log file from the computerized device (or the network storage element) to a post-printing processing device using the computerized network after receiving a request for the error log file. The post-printing processing device unwinds the printed roll and automatically stops the unwinding process at locations of the printing errors based on the error log file.

  • Patent number: 8744328
    Abstract: A fluid delivery system is controlled to adjust a release fluid delivery rate to a rate that is predetermined to be effective for fusing a next sheet in a print job before the sheet arrives at a fusing nip. Predetermined rates and corresponding media types may be stored in memory. A controller controls the fluid release system for a print job in accordance with a print job schedule based on the predetermined fluid delivery rates.

  • Patent number: 7900906
    Abstract: A method (200) and apparatus (100) control feed commitments based on feedable capacity. The apparatus may include a source (122) of feedable media sheets and a feeder module (120) coupled to the source of feedable media sheets, the feeder module configured to control the source of feedable media sheets. The apparatus may include a marking engine (132) coupled to the source of feedable media sheets, the marking engine configured to mark images on media sheets fed by the source of feedable media sheets. The apparatus may include a marker module (130) coupled to the marking engine, the marker module configured to control the marking engine. The apparatus may include a scheduler module (110) coupled to the feeder module and the marker module, the scheduler module configured to schedule feed commitments for the feeder module and mark commitments for the marker module.

  • Patent number: 7690642
    Abstract: A method maintains an environment within an interior of a sheet feeder during dead-cycling of an image forming device to which the sheet feeder is operatively connected. The method jets pulses of air into the interior of the sheet feeder that houses two or more pieces of media therein while the image forming device is dead-cycling. By the method, the attractive forces between two pieces of adjacent media. In a stack are reduced or minimized, and feeding of multiple sheets can be reduced or eliminated.

  • Patent number: 7464926
    Abstract: A pneumatic sheet feeder is selectively actuable to acquire a sheet from a stack and transport the sheet towards a take-away nip. The feeder includes a feedhead having an acquisition surface substantially aligned with the take-away nip. A sensing apparatus detects three separate distances between the stack and the acquisition surface at three separate locations over the stack. The stack is then tilted based upon the distances sensed by the sensors. In embodiments, the feedhead has two sensors, and moves so that the third distance can be measured by one of the sensors. In other embodiments, the feedhead includes three sensors for measuring each of the distances.
