摘要： Predetermined geometric constructs reduce heat loss in a vacuum platen and assist in the reduction of paper cockle in ink-jet printing. A vacuum platen for supporting media during printing is provided with a plurality of heating elements and surfaces interspersed with vacuum ports. The heater elements are laid into surface channels of the platen such that an insulative gap separates the heaters from the main platen support structure. In an alternative embodiment, an insulative gasket is provided for the gap.

摘要： Described herein is a print medium support mechanism for supporting a print medium such as paper in a print zone adjacent a printer's printhead. The print medium support mechanism includes at least one drive roller positioned upstream from the print zone of the printer to feed paper into the print zone. An upper print media guide is positioned adjacent the drive roller between the drive roller and the print zone to contact and support the paper from above. A lower print media guide is mounted downstream from the upper print media guide to pivot between retracted and non-retracted positions relative to the print zone. When in its non-retracted position, the lower print media guide contacts and supports the paper from below. The support of the upper and lower print media guides against opposite sides of the paper is primarily responsible for establishing the shape and angle of the paper as it passes through the print zone. The print medium support mechanism includes a pivot stop which is adjustable to set the vertical position of the lower print media guide relative to the upper print media guide when the lower print media guide is pivoted to its non-retracted position. This effectively establishes a desired print medium shape and angle. A separate media-to-printhead spacing adjustment mechanism is provided for adjusting the vertical positioning of the printer's printhead relative to the paper. Because of this, the media-to-printhead spacing can be set without affecting the settings made to obtain the optimal print medium shape and angle.

摘要： A paper handling system is provided which allows for controlled passage of a pivot between a normally biased initial position and a task-performing position. The pivot includes a sheet-directing member and a track which is fixed relative to the sheet-directing member and is movable to the task-performing position in opposition to pivot bias. A follower, which is configured for selected travel along the track, selectively applies a force against the track in opposition to biased sheet-directing member movement. A processor-controlled printhead carriage is used to trigger and then to regulate pivot rotation.

摘要： A locking system is described for detachably securing two workpieces together (e.g., two housing sections). Elongated arms are carried by one workpiece and a corresponding opening(s) is present in the other workpiece. The outer end of each elongated arm is resiliently deflectable so that it is deflected when being inserted into the opening in the one workpiece; then the arm springs back. A locking arm on the second workpiece is then able to move behind the end of the elongated arm to restrict deflection of the arm, thus preventing any unintentional unlocking of the two workpieces.

摘要： Separator assembly for use with printers is described herein. One example separator assembly includes a separator pad movable between a first position and a second position such that the separator pad is to engage a leading edge of a print media in the second position. A cam is rotatable between a third position and a fourth position to move the separator pad from the first to the second position.

摘要： Methods, printers, and control panels for printers are disclosed. An example printer includes a control panel, a print substrate path exit to output a print substrate from the printer in response to a printing task, and a control panel actuator to move the control panel from a first position in which the control panel at least partially obstructs a print substrate from passing through the print substrate path exit to a second position in which the control panel does not obstruct the print substrate from passing through the print substrate path exit.

摘要： A printing system includes multiple print units which each have one or more printbar assemblies to transfer an imaging medium onto a print media. An individual print unit can include a heater system to dry the imaging medium transferred onto the print media by the one or more printbar assemblies of the individual print unit. For a printing system with two print units, a first percentage of the imaging medium is transferred onto the print media, the print media is advanced beyond the one or more printbar assemblies of the first print unit, and a first heater system dries the first percentage of the imaging medium. A second percentage of the imaging medium is then transferred onto the print media, the print media is advanced beyond the one or more printbar assemblies of the second print unit, and a second heater system dries the second percentage of the imaging medium.

摘要： A system for regulating the vacuum hold pressure in a printer based upon the physical characteristics of the print media that is directed through the printer. In one embodiment, the characteristic of a sheet of media is detected before or as the sheet reaches the carrier. The vacuum pressure level is thus regulated in response to the physical characteristic of the sheet, thereby to have applied to that particular media a level of vacuum pressure that prevents problems that arise when pressure levels are too low (for example, inadvertent shifting of the paper) or too high (for example, paper deformations that reduce print quality).
