  • Patent number: 8965245
    Abstract: An electrostatographic printing apparatus that includes a charge receptor endless belt; a transfer nip including a BTR roll in contact with the charge receptor at a transfer zone, a continuous media supplied to the transfer zone, and the transfer nip adapted for systematic engagement and disengagement with the continuous media for synchronization of image transfer from the charge receptor to the media. More specifically, in response to recognition of imaging inconsistencies such as belt seams, test patches, or label format pitches, the endless belt disengages from the continuous media at the BTR roll. The BTR roll is appropriately turned on and off and the continuous media reversed in direction commonly known as a ‘Pilgrim step’, then returned to normal direction to synchronize the transfer of images to the continuous media, wherein there is substantially zero wrap of the continuous media on the BTR roll during the engagement of the continuous media with the charge receptor belt.

  • Patent number: 8591016
    Abstract: A method for delivering molten ink to a printing mechanism alternates between a first and second reservoir receiving molten ink from a receiving ink reservoir while providing ink from the other of the first and second reservoirs to a printing mechanism. The alternation of the two reservoirs is achieved with coordinated operation of two actuators operatively connected to two seal members.

  • Patent number: 8494412
    Abstract: Systems and a method for image forming systems to skip over the non-printing photoreceptor area in order to not skip a label position on a continuous print web medium. A vacuum assembly is coupled to a controller that controls different vacuum pressures at each vacuum roller therein. The vacuum rollers provide drag and drive forces to skip a seam of the photoreceptor and a residual length based on the number and size of images on the photoreceptor.

  • Patent number: 8303098
    Abstract: A system and method is provide for delivering molten ink to a printing mechanism including receiving molten ink in a receiving reservoir, and alternating which of a plurality of reservoirs is opened to the receiving reservoir to receive molten ink while at least one other of the plurality of reservoirs is opened to dispense molten ink to the printing mechanism, in response to the level of ink in a reservoir dispensing molten ink to the printing mechanism.

  • Patent number: 5690311
    Abstract: A clamp for holding an analyzer in place on a horizontal surface, comprising an entrance mouth angled to allow insertion of a bracket of the analyzer without initial accurate alignment, and a tongue-and-opening interlock between the clamp and the bracket on the analyzer, sized to give limited sideways movement between the clamp and analyzer, once the clamp is locked onto the bracket. The clamp is locked to the bracket using a spring effective to adjust for dimensional variations.
