摘要： An ink-jet printer having improved print quality and full color printing capability on plain paper media. To accommodate placement of both input and output media trays on the same side of the printer housing for operator convenience, a paper path with a direction reversal is employed. A paper preconditioning preheater with a curved surface and a multi-purpose paper path component accomplish the direction reversal. The paper path component is a unitary component which employs curved ribs to reduce the contact area with the medium and reduce static charge buildup, and has slots formed therein to release water vapor given off by the medium when preheated. The component permits paper to be loaded manually via a second manual feed path, through a housing, and upon opening a rear access door in the housing, such component is easily removable to facilitate operator access to the paper path and electrical components.

摘要： Two printing-medium guide systems restrain the medium. One is in an area upstream (along the direction of medium advance) from the pen, and extending laterally across the width of the medium except in one or more regions laterally near the engagement of a print-medium advancing device. The other guide system is disposed laterally from the pen, and extends laterally across the medium only in one or more regions laterally near the engagement of the advancing device. Preferably these "one or more regions" are only near the lateral edges of the medium--so that (1) the first guide system restrains the medium over an area that stops short (ideally about 11/2 centimeter short) of the lateral edges; and (2) the second guide system is bifurcated, disposed laterally in two directions from the pen, and restrains the medium across only the lateral edges of the medium (most preferably in a strip whose width is a few millimeters, ideally 3 mm). Preferably a human-actuable control selects a print-medium width, and shifts at least one bifurcation of the second guide system. A tensioning system, longitudinally beyond the marking head from the medium advancing device, and generally aligned laterally with that device, tensions the medium away from the advancing device to hold the medium taut at the pen. Preferably the advancing and tensioning devices are very closely spaced upstream and downstream, respectively, from the pen zone. When tensioned, the medium moves a normal distance through the apparatus at each operation of the advancing device; but after a trailing edge of the medium passes the advancing device (so that the medium is advanced only by the tensioner and no longer tensioned), the advance distance is decreased (preferably by about half).
摘要翻译：两个打印介质导向系统限制介质。一个是在笔的上游（沿着介质前进的方向）的区域中，并且横向延伸穿过介质的宽度，除了在打印介质前进装置的接合附近的一个或多个区域中。另一个引导系统从笔的横向设置，并且横向延伸穿过介质，仅在横向靠近推进装置的接合的一个或多个区域中延伸。优选地，这些“一个或多个区域”仅在介质的侧边缘附近，使得（1）第一引导系统将介质限制在停止短的区域（理想地约为1 + E，fra 1/2 + EE厘米短）; 和（2）第二引导系统被分叉，从笔的两个方向横向设置，并且限制介质仅横过介质的侧边缘（最优选地在宽度为几毫米的条带中，理想地为3mm）。优选地，人可起动控制选择打印介质宽度，并移动第二引导系统的至少一个分支。纵向超过标记头从介质推进装置延伸并且与该装置大致对准的张紧系统使介质紧张地从推进装置拉紧以将中间张紧在笔上。优选地，推进和张紧装置分别与笔区分开的上游和下游非常紧密地间隔开。当张紧时，在推进装置的每次操作时，介质移动通过装置的正常距离; 但是在介质的后缘通过前进装置（使得介质仅由张紧器前进并且不再张紧）之后，提前距离减小（优选地大约一半）。

摘要： A service station for use with an inkjet printer is described. The service station includes a sled that is mounted to the printer's chassis. Caps and wipers can be mounted on the sled for each of the printer's movable carriage-mounted printheads. The sled and the chassis, and the sled and carriage, are each cam-coupled so that movement of the carriage produces slight vertical and lateral movement of the sled out of a nominal position to automatically place the sled in one of three primary positions relative to the carriage: an elevated position for capping the printheads, an intermediate position for wiping the printheads and a lowered position for free reciprocal movement of the carriage without interference between the printheads and either the caps or the wipers. A wiper structure according to the invention includes a pre-loaded spring and wiper blades made of a relatively stiff material so that the wiper blade angle of attack is maintained close to 90.degree., resulting in good wiping of the printheads. The spring can have a low spring constant so that good control of wiping forces is maintained. The wiper blades are made of an injection moldable material. For example, the wiper blades can be made of an injection moldable polymer such as olefin polymers or polyolefin alloys. In one particular embodiment, the wiper blades are made of a blend of polypropylene and polyethylene. Alternatively, the wiper blades can be made of an engineering thermoplastic elastomer (ETE).

摘要： A color imaging system in which the lamp spectrum is tuned so that, in the charge coupled device, the signal to noise ratio is maximized for all three RGB channels equally. This result is obtained by a process wherein the fluorescent lamp output is adjusted by alteration of the relative amounts of red, green and blue phosphors which coat the inside surface of the lamp. In this manner, when the lamp spectrum is tuned so that the RGB channels of the CCD have equal levels when scanning a white background, the signal to noise ratio can be maximized for all three channels equally. Thus, it is possible to scan a white paper without saturating and all three colors can be scanned simultaneously, since the lamp brightness can be set at a level which maximizes signal strength for all three color signals. That is, the lamp output spectrum and the RGB response of the CCD are tuned to provide balanced system response.
摘要翻译：一种彩色成像系统，其中灯光谱被调谐，使得在电荷耦合器件中，所有三个RGB通道的信噪比最大化。该结果通过以下方法获得：荧光灯输出通过改变涂覆在灯的内表面上的红色，绿色和蓝色荧光体的相对量来调节。以这种方式，当灯光谱被调谐使得当扫描白色背景时CCD的RGB通道具有相等的电平时，对于所有三个通道可以均衡地使信噪比最大化。因此，可以扫描白皮书而不饱和，并且可以同时扫描所有三种颜色，因为灯的亮度可以被设置为使得所有三种颜色信号的信号强度最大化的水平。也就是说，调整灯的输出光谱和CCD的RGB响应以提供平衡的系统响应。

摘要： A service station for use with an inkjet printer is described. The service station includes a sled that is mounted to the printer's chassis. Caps and wipers can be mounted on the sled for each of the printer's movable carriage-mounted printheads. The sled and the chassis, and the sled and carriage, are each cam-coupled so that movement of the carriage produces slight vertical and lateral movement of the sled out of a nominal position to automatically place the sled in one of three primary positions relative to the carriage: an elevated position for capping the printheads, an intermediate position for wiping the printheads and a lowered position for free reciprocal movement of the carriage without interference between the printheads and either the caps or the wipers. According to the invention, wipers are biased against corresponding print cartridges such that the wipers that wipe the printhead of a print cartridge dispensing pigmented ink are biased against the printhead in a different manner, e.g., with greater force, than wiper blades that wipe the printhead of a print cartridge dispensing dye. Differential wiping can be obtained by varying the spring constant of springs used to bias the wipers against the printheads. In one embodiment, leaf springs used to bias the wipers are varied in width and/or thickness to produce differential wiping force. In one embodiment of the invention, print cartridges that dispense pigmented ink are spitted to wet the printhead before wiping.

摘要： A screen-printed reflector reflectively redirects light from a scanner bulb in a substantially uniform illumination pattern across a desired scan area of a document to be scanned. A middle or central portion of the reflector is printed with a non-reflective pattern, while the end portions of the reflector are composed of highly reflective polyester textured matte that in combination with the non-reflective pattern substantially equalizes the illumination across the desired scan area of the document being scanned. The manner of using and constructing the screen printed reflector, provides a fast and efficient method for tuning a light distribution profile to provide a sufficient light reflective pattern that compensates for non-uniform light distribution patterns produced by scanner bulbs.

In one embodiment of the invention, prior to wiping the printhead of a print cartridge, the print cartridge is spitted to wet the printhead. Such spitting is particularly beneficial for a print cartridge that dispenses a pigmented ink (frequently a black ink), since the pigmented ink tends to crust on the printhead more than inks that are dyes. Preferably, a plurality of drops of ink are spit from the print cartridge at each of a plurality of frequencies. The method according to the invention is applicable to printers including one or more print cartridges.

摘要： The temperature of the ejector (12) of a thermal ink jet print head (10) is maintained within acceptable operating limits by measuring the current temperature, predicting the heat loading on a subsequent pass over a printing medium (32), and adjusting the temperature of the ejector (12), as necessary, by heating the ejector (12) or modifying the operation of the printer (60) to permit cooling of the ejector (12). The temperature of the ejector (12) is preferably measured by a thin film temperature measurement resistor (94) codeposited onto a substrate (14) with the thin film ejection resistors (22) that generate the droplets ejected from the ejector (12). Heating of the ejector (12) is preferably accomplished by passing a low level current through the ejection resistors (22). Cooling is preferably accomplished without the use of a fan by delaying the printing pass, or reducing the heat load during the printing pass by slowing the printing rate during that pass only.
