摘要： A printer has a media transport with a rigid, air-transmissive platen. A movable air-transmissive flexible web overlays the platen. A suction device communicates with the platen to draw air through the web and through the platen such that a sheet of media carried on the web is biased toward the platen. A valve sheet overlays or underlies the platen, and includes a plurality of shut-off elements, each movable in response to temperature changes between a closed position in which the element contacts a portion of the platen to prevent air flow through that portion of the platen, and an open position, in which the element is spaced apart from the platen to admit air to the platen portion. The shut off elements may include resistive heaters and bimetallic strips so that application of electricity generates heat to flex the strip to an open position.

摘要： An ink-jet hard copy apparatus provides a flow of air across the printing surface of a sheet of print media during printing operations. The airflow scrubs the boundary layer of the printing surface such that paper cockle is reduced by resultant improvement in drying time. A writing instrument deflector is used to prevent substantial interference with ink droplet flight trajectories due to positive airflow through the print zone.

摘要： A system for regulating the vacuum hold pressure in a printer based upon the stiffness of the print media that is directed through the printer. In one embodiment, the stiffness 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 stiffness measurement 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). A sensing technique for alternatively sensing stiffness and paper thickness is also provided.

摘要： A carriage drive system includes a carriage driven along a carriage path under a force generated by a drive motor. The driving force is coupled to the carriage by a drive belt. High frequency vibrations occurring in the drive belt are isolated from the carriage to improve print quality or scanning accuracy. Vibrations are introduced to the drive belt by the drive motor, the connection between the drive motor and the drive belt or from another source. High frequency decoupling is achieved using a spring connection which serves as a low pass filter of vibration frequencies. In addition, a linear encoder is included on the carriage for detecting carriage position. Such linear encoder samples carriage position at a rate fast enough to enable compensation for low frequency carriage vibrations.

摘要： A carriage drive system includes a timing belt pivotally anchored to a carriage. A drive motor rotates the timing belt, moving the carriage along a carriage path. The drive belt moves along a pair of pulleys. A first pulley is coupled to the motor's drive shaft. A second pulley is coupled to an idler spring. The idler spring determines the belt tension when the belt is stationary. Acceleration of the carriage alters the belt tension. A pivot connection occurs between the drive belt and the carriage. During acceleration, the pivotal connection rotates shortening the effective length of the belt, which in turn stretches the idler spring, and increases belt tension. While the carriage is at rest or moving at constant velocity, the pivot connection serves to reduce side load impact on the drive motor's shaft and windings. The pivot connection also isolates the carriage from high frequency vibrations.

摘要： An inkjet printer includes a microwave drying station passing media through a waveguide thereof. A vacuum source coupled to the waveguide draws air into the waveguide and thereby aides in disturbing and scrubbing a boundary layer of vapor at the media surface otherwise hindering efficient drying of media thereat. Supporting the media on a perforated belt through the waveguide couples media to the belt by vacuum force and thereby contributes to an overall media feed mechanism.

摘要： Techniques for providing a face down orientation of printed media at a normally face up output of a printer. One technique achieves correct order orientation in a printer having a duplexing function, and includes printing a page of the print job at a print area, passing the page through a duplexing media path to reorient the page in a page down orientation, passing the page through the print area in the page down orientation without conducting a printing operation, and passing the page from the print area to an output area in correct order orientation. Another technique includes advancing a page from an input source to a print area, conducting printing operations on the page at the print area, transporting the page away from the print area, diverting the page into an auxiliary media path portion and transporting the page, leading edge first, until a trailing edge of the page passes a diverter location, transporting the page in the reverse direction such that the trailing edge now becomes the leading edge, and diverting the present leading edge of the page along a media path leading to the normally face up output, such that the page is presented to the normally face down output in a face down orientation.

摘要： A carriage is driven along a carriage rod. The carriage includes a roller or a sled which runs along a track. As the carriage moves along the rod the roller or sled runs along the track. Defects in the roller or bumps along the track cause the carriage to rotationally vibrate about the carriage rod during movement. A vibration isolator (e.g., tuned spring) is included at the connection between the carriage and the roller or sled. Such isolator absorbs vibrations introduced by the roller, sled or track. The reduced vibrations lead to improved print quality for printers having smaller dot size or increased precision.

摘要： A printer has a media transport with a rigid, air-transmissive platen. A movable air-transmissive flexible web overlays the platen. A suction device communicates with the platen to draw air through the web and through the platen such that a sheet of media carried on the web is biased toward the platen. A valve sheet overlays or underlies the platen, and includes a plurality of shut-off elements, each movable in response to temperature changes between a closed position in which the element contacts a portion of the platen to prevent air flow through that portion of the platen, and an open position, in which the element is spaced apart from the platen to admit air to the platen portion. The shut off elements may include resistive heaters and bimetallic strips, so that application of electricity generates heat to flex the strip to an open position.
