摘要： An improved printing apparatus provides for very accurate synchronization between cut sheet print media and the unfixed image which is conveyed on an Intermediate Transfer Member (ITM) such as a belt or a drum, and which is targeted for said print media. The printing apparatus is constructed as a single-pass ITM-based electrophotographic (e.g., laser) printer, and the length of the input print media pathway prior to image-to-media transfer is significantly shorter than the sum of the lengths of the image travel along a photoconductive drum and ITM. The print media is typically launched after imaging has been initiated on the photoconductive drum by an imaging apparatus. Variance in the leading edge of the print media with respect to the leading edge of image can be introduced due to phenomena such as pick errors, velocity variation, and uncertainties in the paper stack height. The present invention minimizes this leading edge variance to a tightly targeted specification by accurately sensing the positions of the print media and the ITM image, and correcting the print media's position by controlling the velocity of the print media prior to arriving at the transfer nip. In addition, the present invention detects the presence of print media within the sheet feeder cassette tray before imaging is started in the ITM belt, thereby minimizing the amount of waste toner generated by the printing apparatus. The imaging procedure on the ITM belt typically begins at a time prior to the printer controller having precise knowledge as to the location of the “next” sheet of print media within the combination of the input print media pathway and sheet feeder cassette tray.

摘要： A method of minimizing error in an estimate of a position of a sheet of print medium in an electrophotographic machine includes providing a transport system including a gearing system to drive a roll for moving the sheet of print medium along a print medium path. The gears are in constant mesh with each other and with an actuator. The electrophotographic machine is provided with a toner transfer point at which the toner can be transferred to the moving sheet of print medium. A sensor is placed at a set distance away from the transfer nip along the print medium path. This distance is approximately equal to an integer multiple of the resulting distance traveled by the medium during one revolution of the lowest frequency component of the transport system. The frequencies associated with all other components in the transport system, including the actuator and an encoder wheel, are designed to be an integer multiple of this lowest frequency. The gearing system is actuated with a rotating actuator such that the actuator rotates approximately an integer number of times during a corresponding rotation of the lowest frequency component. An encoder wheel is also used to provide feedback to a control algorithm. A position of the sheet of print medium is sensed with the sensor.

摘要： Correction of rotary encoder eccentricity in an image forming device having a motor controller using period and position pulse train feedback signals. A motor includes an encoder disc rotating with the motor and at least two encoder sensors disposed at different circumferential positions about the encoder disc. A controller may use a high speed clock to calculate a corrected speed count based on speed counts determined from the number of clock cycles that elapse per cycle of pulse trains from the encoders. The controller may also calculate a corrected position count based at least partly on one or more position counts determined from the number of clock cycles that elapse between periodic sampling points and transitions of encoder pulse trains. The corrected position count may also be calculated based on a position count and one or more speed counts.

摘要： An improved variable speed fan controller for use in devices such as laser printers. The controller automatically adjusts its output signal to fans such that a fan quickly settles into an appropriate operating speed, even if the fan has been newly installed into the equipment. The controller can store values in non-volatile memory, if desired, to keep track of recent changes in the fan's operating parameters and corresponding control signal values. The controller is able to control relatively inexpensive fans that don't necessarily operate at a predictable fan rotating speed under repeatable conditions and control signals, by controlling the fan to an initial or predetermined rotating speed; if the fan isn't running within a suitable range of rotational speeds, then determining whether a fine or coarse adjustment should be made to the fan's rotational speed. The controller makes appropriate adjustments until the fan's rotational speed is within acceptable operating tolerances.
摘要翻译：改进的变速风扇控制器，用于激光打印机等设备。控制器自动将其输出信号调整到风扇，即使风扇已经新安装到设备中，风扇也会迅速稳定在适当的运行速度。如果需要，控制器可以将值存储在非易失性存储器中，以跟踪风扇运行参数和相应控制信号值的最新变化。控制器能够通过将风扇控制在初始或预定的转速来控制在可重复的条件和控制信号下不一定在可预测的风扇转速下工作的相对廉价的风扇; 如果风扇没有在合适的转速范围内运行，则确定是否应对风扇的转速进行微调或粗调。控制器进行适当的调整，直到风扇的转速在可接受的工作公差范围内。

摘要： In an electrophotographic print mechanism wherein one motor drives two or more removable toner cartridges, the presence of each cartridge is sensed and reported to the motor controller. If one or more cartridges are removed, such as for single-color printing, the motor control equation parameters are altered to compensate for the altered static torque load experienced by the motor. The parameters may be the proportional, integral, and/or derivative gains for one or more PID controllers.

摘要： A method of media-to-image registration sets a top writing line margin on a print medium within an electrophotographic machine. Movement of a substantially stationary sheet of print medium along a print medium path within the electrophotographic machine is initiated. An image associated with the sheet of print medium is scanned onto a developing unit. The scanning step commences before the initiating step. Toner is adhered to the image on the developing unit. The toner is transferred from the developing unit to a moving toner transfer medium. The electrophotographic machine is provided with a toner transfer area in which the toner can be transferred to the moving sheet of print medium. A speed of the movement of the sheet of print medium is adjusted such that the toner is transferred from the moving toner transfer medium to a desired area on the sheet of print medium within the toner transfer area. The sheet of print medium moves substantially continuously between the initiating step and a time of the transfer of the toner to the sheet of print medium.
