摘要： A dam has a plurality of substantially parallel ribs with recesses therebetween. At least one of the recesses has a pad therein with its sheet engaging surface being interior of the sheet engaging surfaces of the ribs. The rib surfaces, which are engaged first by the sheets being fed, have a lower coefficient of friction with the sheets than the sheet engaging surface of the pad. If more than one sheet is fed from a stack to the dam, the sheets will strike the rib surfaces first and then the pad surface if not separated from each other by the rib surfaces. Since the pad surface has a coefficient of friction substantially equal to the sheet to sheet friction, this step function in friction helps to separate the top sheet from the next adjacent sheet.
摘要翻译： 坝具有多个基本上平行的肋，其间具有凹部。 凹槽中的至少一个具有垫，其中片接合表面是肋的片接合表面的内部。 首先由进给的片材接合的肋表面与片材的片材接合表面具有比片材低的摩擦系数。 如果多于一张纸从堆叠送入大坝，纸张将首先撞击肋条表面，然后如果不通过肋表面彼此分离，则焊盘表面。 由于垫表面的摩擦系数基本上等于片材与片材的摩擦系数，所以摩擦的这一步骤有助于将顶片与下一个相邻的片材分开。

摘要： The number of pages of a print job received at printer (10) is determined (256). If the number of pages is low, printing is conducted at intermediate speed (262). If the number of pages is higher, printing is conducted at high speed (254). If the number of pages is not known, a default is selected (260). The default often will be to print at intermediate speed because most jobs are short. If high speed printing is in progress when a job is received, the next job is printed at high speed (254). Alternatively, a predetermined number of the first pages of a job may be printed at intermediate speed.

摘要： A staging assembly for use in an image forming apparatus. The image forming apparatus includes a paper feed assembly having a plurality of rollers for feeding a transfer sheet to an electrophotographic assembly. A removable idler gear is interposed between the paper feed assembly and the electrophotographic assembly, and drives the paper feed assembly when installed. A staging assembly drives the paper feed assembly when the idler gear is removed and includes a rotatable drive element for connection to and rotation of one of the rollers; a drive unit for rotatably driving the rotatable drive element; and an electrical connector for electrically connecting the staging assembly to the electrophotographic assembly.

An engine dynamically decides which process speed to warm up to based on a number and size of pages currently submitted to the engine, and thus deliver the best job time dynamically. The engine also takes into account its condition and a condition of a fuser, and dynamically selects a substantially optimum point of operation.

摘要： A control system for a cooling fan of a laser printer enables selection of fan speed based on the actual degree of usage of the printer. The system provides first and second sets of fan speeds where each set contains information corresponding to a plurality of fan speeds. Information regarding the current operational condition of the fuser of the printer is periodically obtained, preferably during a preset interval. The fan is then operated at one of the fan speeds of the first or second set of fan speeds, with the selection of the first or second set and the selection of one of the fan speeds based on the current operational condition of the fuser. In this manner, the speed of the fan is substantially continuously controlled based on the operational condition of the printer.

摘要： A laser printer having a rotating mirror (116) and a heat fuser (220) is operated with a sequence of standby conditions. At the end of a print job mirror (116) is continued to be rotated at printing speed while the temperature of fuser (220) is reduced somewhat. This is maintained for a short time, after which the speed of rotation of mirror (116) is reduced significantly and the fuser (220) temperature is reduced significantly. This is maintained for a time, after which the mirror is no longer rotated (or, if practical, is rotated very slowly) and the fuser temperature is further reduced. At any time when a subsequent print job is received, the mirror and fuser are brought to printing state and the period of times are next started from a beginning state.

摘要： Toner hopper (1) of a printer (70) has a stirring paddle (3) with an encoder wheel (30, 50) mounted on paddle shaft (5). The drive connection to paddle (3) is through a torsion spring (60). Data processing apparatus determines paddle acceleration or deceleration (90, 94, 98, 102) and executes a table look-up to determine scaled amounts of subsequent movement (92, 96, 100, 104). Steady state movement is a unitary (unscaled) amount (106). These amounts are totaled (93) and used to define yield at the torsion spring, which corresponds to amount of toner in the hopper. This eliminates hardware in previous embodiments at the drive motor to signal actual rotation of the drive motor.

摘要： A substrate sensing mechanism is provided for use in a printer output bin. The sensing mechanism includes a flag having a shape such that when one or more substrates, which have been removed from the bin, are manually reinserted into the bin, the one or more substrates are directed beneath the flag without causing a substrate feed failure. The flag is also positioned and shaped so as to move to a full bin position when a portion of one or more curled substrates extends to or above a level of the substrate output path immediately adjacent the bin entrance.
