摘要： Compensation for pixel aberrations in a laser printer is accomplished by altering pixels in accordance with pixel location. A projection of a scan line is skewed with respect to a line normal to the surface of an optical photoreceptor (OPR), which results in a change in the shape of projected pixels. Selected pixels are augmented in order to adjust their shape. The additional optical energy may be applied at the sub-pixel level so that a threshold of energy depletion on an optical photoreceptor (OPR) is not reached where image development would occur. Alternatively, the additional energy may be applied in a manner which provides additional development to simulate a pixel having a desired width across a scan line. The invention allows a scan line to be produced in which pixels across the scan line are made more uniform.

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： 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： 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.

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.
