摘要： A multiple media sheet stack selection mechanism for selectively presenting multiple media sheet stacks to the same sheet separation and feed mechanism. The multiple media stack selection mechanism includes a primary sheet holder and at least one secondary stack holder. In the first embodiment, the multiple media stack selection mechanism includes a rotatable feed arm mechanism for holding the second paper stack and for positioning the second paper stack for picking and advancement. In the second embodiment, the multiple media sheet stack selection mechanism includes a paper stack gripping device for holding a second paper stack and for positioning the second paper stack for picking and advancement. In both the first and second embodiment, the paper stacks are positioned at a near vertical angle. The near vertical angle provides additional advantages in that the gravity force assists in constantly urging the sheets toward the feed zone, and results in a greater feed reliability. In the third embodiment, the multiple stack selector includes two tray mechanisms that selectively position two separate stacks of paper to the same picking and advancement device by the use of a dual cam and associated cam follower arrangement.
摘要翻译：一种多媒体纸张堆叠选择机构，用于选择性地将多个介质纸张堆叠呈现给相同的纸张分离和进给机构。多媒体堆栈选择机构包括一个主要的片材保持器和至少一个二次堆叠保持器。在第一实施例中，多媒体堆栈选择机构包括用于保持第二纸叠的可旋转进给臂机构和用于定位用于拾取和推进的第二纸叠。在第二实施例中，多媒体纸张堆叠选择机构包括用于保持第二纸叠的纸叠夹持装置，并且用于定位用于拾取和推进的第二纸叠。在第一和第二实施例中，纸叠定位在接近垂直的角度。近垂直角度提供了额外的优点，因为重力有助于不断地将片材推向进料区，并且导致更大的进料可靠性。在第三实施例中，多堆叠选择器包括两个托盘机构，其通过使用双凸轮和相关联的凸轮从动装置选择性地将两个单独的纸堆叠定位到相同的拾取和推进装置。

摘要： An apparatus for dispensing toner in an electrophotographic printing system includes a housing for containing a supply of toner and toner filled containers for replenishing the supply of toner. Toner is allowed to flow to a developer assembly in the electrophotographic printing system by removal of a housing toner seal. The bottom of the container is dimensioned so that it can be inserted through the opening in the top of the housing and the opening in the top of another substantially identical container. A toner dam seal is attached to the container to close the bottom opening. In the preferred embodiment, the toner dam seal includes a length of flexible material for use in removal of the toner dam seal. In an alternative embodiment, cutting blades are attached to the interior of the sidewalls of both the housing and the container for cutting the toner dam seal upon installation of the container into the housing or into a previously installed container.

摘要： An apparatus for refilling an electrophotographic imaging system. A refill pack is constructed around a frame. A collapsible bag, which is permanently attached to the top of the frame, along with a removable seal, which is attached to the bottom of the frame, defines an internal volume that contains the developer particles. The refill pack attaches to a receiving area on the cartridge. A new cartridge includes a flexible cover attached over an opening in the receiving area. Once the refill pack is attached to the receiving area, the removable seal is removed. As the removable seal is removed, a cutting edge on the removable seal cuts the flexible cover, opening the cartridge. Removal of the removable seal also releases the developer particles from the internal volume, allowing them to enter the cartridge thereby refilling the cartridge. Additional refill packs may be added over the top of a spent refill pack. However, the receiving area of the cartridge allows a maximum number of refill packs.

摘要： An apparatus for detecting a transfer medium (i.e., paper) accordion jam in a processing path of a laser printer comprises an accordion detection flag pivotally disposed near the processing path. In the event an accordion jam occurs to the transfer medium in the processing path, an accordioned portion of the transfer medium presses against the flag thereby forcing the flag to pivot for signaling the accordion jam. A preferred method for detecting an accordion jam comprises (a) storing a first time increment indicia indicative of a length of time elapsed for a leading and trailing edge of the transfer medium to pass a reference point in the processing path; (b) storing a second time indicia indicative of a point in time that the leading edge of the transfer medium forces the fuser sensor flag to activate the fuser sensor; (c) storing a third time increment indicia indicative of time elapsed since the second time indicia, measured at a point in time signaled, alternatively, by (i) the trailing edge of the transfer medium causing the fuser sensor flag to deactivate the fuser sensor, or (ii) in the event an accordion effect occurs to the transfer medium, an accordioned portion of the transfer medium forcing the accordion jam flag to deactivate the fuser sensor; and, (d) calculating a difference between the second and third time indicia, and in the event the difference is less than the first time indicia, signaling that an accordion jam has occurred.

摘要： Paper processing equipment such as a laser printer uses a plurality of sensors to detect the presence of paper in the paper path of the equipment. In order to determine the nature of malfunctions indicated by presence or absence of paper at the sensors, data from the sensors is coordinated with information concerning the timing of the data. In one embodiment, a single data signal is used to provide information that a paper supply hopper is empty and that paper is present at an output of a paper sheet pick mechanism. Advantages include simpler operation and the provision of discrete display indicia for different types of malfunctions and paper out conditions.

摘要： Disclosed herein is a uniform heat flux dryer system and method of an ink jet printer, including a 180.degree. contoured paper transport path for transferring paper from an input paper supply tray to an output paper collection tray. During this transfer, the paper receives a uniform heat flux from an infrared bulb which is located at the axis of symmetry for the paper transport path, and reflectors are positioned on each side of the infrared bulb to maximize heat transmission from the bulb to the paper during the ink drying process. Advantageously, the input and output paper trays may be vertically aligned on one side of the printer to facilitate loading and unloading of the paper.

摘要： An intuitive operator panel for machines is provided. A listing of possible functions on a transparent face is located adjacent to each multiple function control or display. A colored background viewable through the transparent face, reduces the readability of the items in the list. A moveable opaque field is located between the transparent face and colored background and increases their readability. The opaque field can be moved by the operator to highlight a desired function from the list. The desired function is highlighted in the list and the machine senses the opaque field's position to determine the function selected. Such a configuration reduces the visual clutter associated with function lists which accompany multiple function controls or displays.

摘要： A combination fusing and media direction control method and apparatus wherein a fuser roller is positioned adjacent to a pair of idler pressure rollers located at predetermined locations adjacent to the surface of the motor driven fuser roller which is operative to receive printed media from a photo-conductive drum within a printer housing. The printed media enters a location between the surface of the fuser roller and one of the idler pressure rollers where it then traverses an approximately 90.degree. contoured path around approximately one-quarter (1/4) of the surface area of the fuser roller where it then exits the fuser roller at the intersection of the fuser roller and the second idler pressure roller. From this point, the direction of media travel is maintained substantially in a horizontal direction until the time the media comes to rest in an output paper collection tray of the printer. A deflection baffle member is provided adjacent the location of the fuser roller and the second idler pressure roller to provide a slight vertical deflection of the fused media so as to maintain its direction of travel into the output paper collection tray substantially flat or horizontal, thereby maintaining the media in the substantially flat or horizontal position over the entire length of the time that the fused paper is being cooled after leaving the fuser roller. This operation in turn serves to minimize and substantially eliminate curl otherwise introduced into the printed media. In alternative embodiments of the invention, the above described media guide control is accomplished by the use of either a contoured drive belt or a contoured deflector plate used in combination with a single idler pressure roller.
