摘要： A printer includes a print mechanism for performing printing operations and a print medium feeding mechanism for feeding a print medium past the print mechanism so that printing operations can be performed on the print medium. The print medium feeding mechanism includes a forward feed apparatus located downstream of the print mechanism for feeding the print medium in the forward direction past the print mechanism and a print medium tensioning apparatus. The tensioning apparatus includes at least one pair of pressure wheels rotatably mounted on the frame and located on opposite sides of a print medium being fed by the forward feed apparatus and means for restricting the rotation of at least one of the pressure wheels, whereby the pressure wheels exert a retarding force on the print medium tending to tension the print medium. Each pressure wheel is constructed so that it is flexible in the axial direction so as to permit lateral movement of a print medium as it passes between the pair of pressure wheels.The print medium feeding mechanism also includes drive means for rotating at least one of the pressure wheels in the reverse direction so as to provide for reverse feed of the print medium. This drive means is coupled through a one way coupling so as not to affect the ability of the pressure wheel to rotate during forward feed of the print medium.

摘要： A consumable supply item for an imaging device holds an initial or refillable volume of ink. Users orient a housing to deplete the ink in a direction of gravity toward a bottom of the interior. The imaging device has a rotating latch. The latch mates with a top of the supply item to keep in place the supply item. Fluid exit and air venting ports reside on a side of the housing that gets inserted first into a container slot of the imaging device. A space separates the ports so a biasing member can push against the housing to assist in ejecting the supply item upon users activating the latch. The ports are separated a maximum distance to facilitate the ejection, while the exit port remains near a bottom to minimize stranding ink. Further embodiments note arrangements, distances and consumer features, to name a few.

摘要： An imaging apparatus includes a print engine having a print zone. A print media feed system transports a sheet of print media in a media feed direction along a media feed path through the print zone. The print media feed system includes a plurality of exit rollers positioned across a width of the media feed path. Each of a plurality of pressure rollers engages a respective one of the plurality of exit rollers to define a plurality of exit nips. A support structure mounts the plurality of exit rollers and the plurality of pressure rollers. The support structure positions the plurality of exit nips in an arrangement to define a transverse path across the width of the media feed path in the direction transverse to the media feed direction, the transverse path having a central portion and elevated portions on each side of the central portion.

摘要： A wiper for an ink jet printhead comprises a monolithic body having a mounting portion and a head portion, the head portion including a wiper portion and a beam portion for supporting the wiper portion on the mounting portion. The mounting portion has a bottom surface and a slot centered in the bottom surface where the slot extends toward the head portion from the bottom surface and receives a mounting beam that is movable. The wiper is characterized in that the wiper portion has two non-parallel side surfaces which diverge from the beam portion and intersect a flat top surface of the wiper portion at acute angles so as to form two parallel wiping edges which may alternately wipe the printhead as the printhead moves back and forth relative to the wiper. Because the side surfaces of the head portion form angles of less than 90.degree. with the top surface there is less tendency for the head to trap and ride on ink wiped from the printhead. The beam portion has a hole extending through it thus making it more flexible. This permits a harder material to be used in the wiper without causing damage to the printhead. The wiper is normally supported on the opposite side of the plane of record feed from the printhead and may be raised into the path of travel of the printhead. An optional blotter may be provided for absorbing from the wiper the ink which is wiped from the printhead.
摘要翻译： 用于喷墨打印头的擦拭器包括具有安装部分和头部部分的整体式主体，头部包括擦拭器部分和用于在安装部分上支撑擦拭器部分的梁部分。 安装部分具有底表面和在底表面中心的槽，其中槽从底表面朝向头部延伸并且接收可移动的安装梁。 擦拭器的特征在于，擦拭器部分具有两个非平行的侧表面，该两个非平行的侧表面与梁部分分开并且以锐角与擦拭器部分的平坦顶表面相交，以便形成两个平行的擦拭边缘，其可以交替地将打印头擦拭为 打印头相对于刮水器来回移动。 由于头部的侧面与顶面形成小于90°的角度，所以头部不易陷入并骑在从打印头擦拭的墨水上的倾向较小。 梁部分具有延伸通过它的孔，使得其更加柔性。 这允许在擦拭器中使用更硬的材料而不会损坏打印头。 擦拭器通常被支撑在来自打印头的记录进给平面的相反侧上，并且可以被升高到打印头的行进路径中。 可以提供可选的吸墨纸，用于从擦拭器吸收从打印头擦去的墨水。

摘要： In an impact typewriter/printer using a daisy wheel typefont a stepper motor for rotating said daisy wheel for character selection purposes and microprocessor facilities for controlling said stepper motor, means are provided for generating tones signalling the occurrence of predetermined events to be brought to the attention of the typist. For that purpose, the microprocessor facilities are used to detect and identify the occurring event and then generate a tone of a predetermined frequency by moving said stepper motor back and forth at given rates whereby the daisy wheel typefont is made to vibrate the surrounding air fluid and generate the acoustical tone.

摘要： A consumable supply item for an imaging device holds an initial or refillable volume of fluid. Users orient a housing to deplete the fluid in a direction of gravity toward a bottom surface of the interior en route to an exit port. The imaging device has a rotating latch to keep in place the supply item during use Users activate the latch to eject the supply item. The latch mates with a notch on the supply item. A first face of the notch angles to allow the latch to swing into and away from contact with the notch while a second face substantially parallels a side of the latch when the latch is engaged with the first face. The faces have differing angles and differing lengths. Further embodiments note angular degrees, biasing members, container slots, and consumer features of the supply item, to name a few.
