    摘要: The method comprises the steps of feeding media from a media roll, arranged about an axis, through an input driving device and an output driving device of the media advance mechanism, wherein the output driving device engages the media with lower friction than said input driving device; releasing said input driving device such that it does not engage the media; and causing the media to move in the media advance mechanism such that the media is pulled taut between the roll and the output driving device and later the media slips with respect to said output driving device, whereby the media is aligned at right angles to the roll axis by effect of the friction between the media and the output driving device.

    摘要: A printing device includes a print media advancement subsystem for providing accurate and timely print media advancement in the printing device. The print media advancement subsystem includes a vacuum chamber for generating a vacuum force through a platen for holding a print media stationary. In response to receiving a print media advance signal from a controller in the printing device, a sealing plate forming a side of the vacuum chamber is removed from the vacuum chamber. When the sealing plate is removed, the vacuum chamber is substantially open to the atmosphere, causing the vacuum chamber to pressurize. The pressurization of the vacuum chamber results in removal of the vacuum force from the print media, allowing the print media to advance along the top surface of the platen with minimal friction.

    摘要: A wet ink printer uses a heated printhead. A platen guides and supports the print medium during printing, and has a plurality of raised ribs. In an example, the ribs extend on the base generally along the advance direction of the print media. Each rib comprises a discontinuous series of rib portions, and wherein between each adjacent pair of ribs is provided a spacing to allow deformation of the print medium towards the platen base.

    摘要: A vacuum holddown device for a hardcopy apparatus, comprising a printing platen with a pattern of through holes and an underlying vacuum chamber, further comprises a member located therebetween and having a substantially similar pattern of through holes, the member being moveable to align the pattern of holes or not so as to respectively interconnect or disconnect the holes in the printing platen and the vacuum chamber. The member may itself define a secondary chamber with which the holes in the printing platen are in communication when not in communication with the vacuum chamber.

    摘要: A media outputting device for a hardcopy apparatus includes a media source and at least one roller having an outer surface with a contact region for engaging media, where the roller is rotatable for outputting the media. The media outputting device also includes a negative pressure mechanism for creating a negative pressure distribution on the contact region where at least one portion of the contact region that is farther from the media source has a greater negative pressure than at least one portion of the contact region that is closer to the media source.
