摘要： Time between recording print on one media sheet and a subsequent media sheet is substantially reduced by ejecting, picking and loading within a single transmission state. In a continuous feed mode multi-sheet job, individual media sheets are continuously picked and loaded. The leading edge of one media sheet is substantially adjacent to the trailing edge of the prior media sheet. A media support plate is maintained in a raised position during the entire continuous feed cycle. The support plate biases a paper stack into communication with a pick roller. As the trailing edge of one media sheet exits the media stack, the leading edge of the next media sheet is already in position for engagement with the pick roller. Upon completion of print recording, a media sheet is ejected into an output tray by accelerating the media sheet. Such acceleration is achieved while remaining in the single transmission state.
摘要翻译：通过在单个传输状态下的弹出，拾取和加载，基本上减少了在一个介质片材和后续介质片材上的记录打印之间的时间。在连续进纸模式的多页作业中，单独的介质纸张被连续地拾取和加载。一个介质片的前缘基本上与现有介质片的后缘相邻。在整个连续进料循环期间，介质支撑板保持在升高位置。支撑板偏压纸叠与拾纸辊连通。当一个介质片的后缘离开介质堆时，下一个介质片的前缘已经处于与拾取辊接合的位置。在完成打印记录之后，通过加速介质片材将介质片材弹出到出纸托盘中。在保持单传输状态的同时实现这种加速。

摘要： A sheet media realignment mechanism is described for use in, for example, a printer. Preferably, the mechanism includes a lever located in the sheet-feeding path adjacent and beneath a rotatable member that mounts a plurality of sheet-feeding rollers. At the beginning of a sheet-feeding cycle, the lever is urged from its extreme upstream pivotal orientation by a pivot-mounted strut into a downstream orientation in which a top sheet of the printer's infeed stack is fed by frictional forces into the feed zone. Upon release of the lever by the strut at a predefined pivotal orientation of the rotatable member, the lever is urged farther into an extreme downstream orientation by the sheet being advanced. After the sheet passes by, the lever is returned to its extreme upstream orientation in which it urges upstream and away from the printer's feed zone any sheets of the stack that inadvertently may have been dislodged and partly advanced downstream and toward the feed zone by frictional forces between the fed sheet and those beneath it. Thus, the lever realigns the sheets of the paper stack after each single-sheet feed into the printer or other sheet media-processing equipment to permit the addition of sheets to the top of the stack without pulling the stack away from the feed zone and to reduce the likelihood of undesirable multiple-sheet picks and feeds.
摘要翻译：描述了用于例如打印机的片材介质重新调整机构。优选地，该机构包括位于片材供给路径中的杠杆，该杠杆邻近并位于安装多个供纸辊的可旋转构件的下方。在送纸循环开始时，杠杆通过枢转安装的支柱从其最上游枢转方向被推动到下游定向，其中打印机的进料堆的顶部片材通过摩擦力进给到进料区。当通过支柱以可旋转构件的预定的枢转方向释放杠杆时，杠杆被片材向前推动进一步向下进入极限。在纸张通过之后，杠杆返回到其最上游方向，在该上游定向中，其推动上游并远离打印机的进料区，堆叠的任何纸张不经意地可能被移动并且部分地向下游延伸并且通过摩擦力朝向进给区在喂食的纸张和它之下的纸张。因此，杠杆将每张单张纸送入打印机或其他纸张介质处理设备中的纸叠重新对准，以允许将片材添加到堆叠的顶部而不将纸堆从进料区域拉出，并且减少不希望的多页选择和进纸的可能性。

摘要： An improved printer paper stack-handling device is described. In its preferred embodiment, the stack-handling device includes a pivot member with a downwardly inclining paper top-of-stack contact surface. The device also includes a force mechanism, e.g. a leaf spring, to pivot the member into contact with the top sheet of a paper stack. The spring and the pivot member's inclined contact surface produce a variable top sheet bias for corresponding variable paper stack heights, to properly laterally align the top sheet against a fixed, opposing guide rail, for feeding to a printer input port.

摘要： A media feed mechanism includes a picking device, a first feedroller and a second feedroller. The picking device picks a sheet of media from a media source. The first feedroller moves the sheet of media along a feed media path. During a skew correction phase, the first feedroller rolls in a forward direction feeding the sheet of media forward and the second feedroller turns in a reverse direction preventing the sheet of media from progressing past a nip of the second feedroller. This results in skew correction. After skew correction is performed, the second feedroller turns in the forward direction advancing the sheet of media for printing.

摘要： A second feed roller of smaller diameter than a first feed roller is included in a media handling system. A print zone is located adjacent to the second feed roller away from the first feed roller to lower the location of the print zone. During ejection, a pivot mechanism moves from a first position adjacent to the printhead to an intermediary position. This causes arms to extend and rails to retract. The motions then pause and/or reverse, prior to full extension and full retraction. Next, the pivot mechanism moves to a second position causing the arms to fully extend and the rails to fully retract. The varied motion (e.g., pause and/or reversal) assures that the arms push at an edge of the media sheet to reliably move a media sheet into an output tray without the media sheet sailing from the printer.
摘要翻译：比第一进料辊小直径的第二进料辊包括在介质处理系统中。打印区域邻近第二进料辊远离第一进料辊定位，以降低打印区域的位置。在排出期间，枢转机构从邻近打印头的第一位置移动到中间位置。这会导致手臂伸展，导轨缩回。然后，在完全延伸和完全缩回之前，运动暂停和/或反转。接下来，枢转机构移动到第二位置，使得臂完全伸出并且轨道完全缩回。变化的运动（例如暂停和/或反转）确保臂推动介质片的边缘以将介质片可靠地移动到输出托盘中，而不会使介质片从打印机上航行。

摘要： An adaptive media handling system is provided for an inkjet printing mechanism having a printhead that prints on media in a printzone. A motor drives a media advance mechanism to move the media through the printzone, where the media is held by a media support member adjacent the printhead. A spacing adjuster is operatively engaged by the motor to position the media support member for a selected spacing between the media and the printhead. Fresh media is picked from a supply container using a lifter member operatively engaged by the spacing adjuster. The spacing adjuster may be a dual-sided cam, with one side for spacing adjust and the other for media picking. Motor rotation of the spacing adjuster adjusts the printhead-to-media spacing to a selected value, for instance, to accommodate manufacturing tolerances, or in response to the type of media or the type of image being printed.

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.
