摘要： A difference in feed roller diameter from one printer to another causes a media to advance by a different amount for a given rotation of a drive shaft to which the feed roller is coupled. Such variation in advance distance is a linefeed error. Mean linefeed error is determined and corrected by printing a test plot having several areas. Each area is formed of the same image pattern, but is printed at a different linefeed error adjustment to compensate for mean linefeed error. The different adjustments are prescribed and span a typical compensation range for a given print engine model. The different adjustment factors cause banding to occur in some areas. The user picks one of the test pattern areas which has the highest print quality (i.e., least or no banding). The linefeed adjustment factor corresponding to such area is used for normal printing.

摘要： In an inkjet printing apparatus an inkjet printhead has a plurality of inkjet nozzles which eject ink onto media located within a print-zone. A drive shaft is located upstream of the printhead and is incrementally rotated to advance the media. The drive shaft has a longitudinal axis, a first radius over a central length and a second radius less than the first radius at a first recess and a second recess, each said recess being peripheral to the central length. A plurality of pinch devices stabilize the media against the drive shaft. A first guide is aligned with the first recess and is spaced from an axis of the drive shaft by a first distance which is less than the first radius. A second guide is aligned with the second recess and is spaced from the axis by a second distance less than the first radius.

摘要： A print media transport assembly for advancing a print media through a print zone includes a primary drive roller rotatably mounted on an entry side of the print zone and a pinch roller rotatably mounted opposite the primary drive roller. The primary drive roller and the pinch roller are adapted to contact the print media and the primary drive roller is adapted to advance the print media through the print zone. The print media transport assembly also includes a secondary drive roller rotatably mounted on an exit side of the print zone and a starwheel rotatably mounted opposite the secondary drive roller. The secondary drive roller is adapted to contact a first side of the print media and the starwheel is adapted to selectively contact a second side of the print media.

摘要： When the data rate of incoming data is less than the print speed, there can be pauses in the print job. During a pause, wet ink may cause cockle growth at a portion of the media sheet within the print zone. To reduce such cockle growth a reduced number of nozzles are used when the data rate is less than the print speed. In particular the print swath is reduced. Only a downstream subset of nozzles are used, in effect shortening the portion of the media sheet receiving ink. The wet portion of the media sheet then is closer to the downstream edge of the print zone and soon away from the printhead. A guide shim also is advanced to maintain a flat media sheet near the active nozzles.

摘要： A wet-dye hard copy apparatus is provided with a vacuum transport for moving print media from and input, through a print zone, to an output. In order to reduce high frequency paper cockle, the print media is subjected to a post-printing predetermined bending while the print dye thereon is drying. In an alternative embodiment, a post-ejection bending heating step is added prior to ejecting a printed print medium to the apparatus output.

摘要： A belt-type support for moving print media such as paper through a printer includes a flexible belt that is supported in a manner such that friction is minimized and such that the paper that is supported on the belt is advanced precisely through the print zone of the printer. The support is provided in conjunction with a uniform distribution of vacuum pressure to the paper carried by the belt. In one preferred embodiment, there is provided a rigid, flat platen for supporting a uniformly porous belt. The platen has a number of rollers on its surface to minimize the friction developed between the platen surface and the moving belt. The platen surface also includes ports to provide a uniform distribution of vacuum pressure to the porous belt. In another embodiment, sliders are carried in the support surface of the platen to minimize frictional contact with the moving belt. Another embodiment includes substantially flat platen surface with a low-friction material layer disposed between the belt and platen surface for facilitating movement of the belt over the platen.
