摘要： A method of determining a relative speed between two separately driven members in an image forming apparatus, includes the steps of: transporting a print medium using a print media transport assembly including an exit nip, the print media transport assembly operable at a first transport speed; driving a rotatable member associated with an entrance nip using an electric motor at a second transport speed which is independent from the first transport speed; transferring the print medium from the exit nip to the entrance nip; detecting an electrical characteristic of the motor when the print medium is present in each of the exit nip and the entrance nip; and determining a relative speed between the first transport speed and the second transport speed.

摘要： In an image forming device where first and second components are disposed in rotating contact with one another, the first component is driven by a first motor and a second component is driven by a second motor through a gear train with some predetermined backlash. The first and second components can be controllably accelerated according to respective first and second velocity profiles. The second component may be accelerated at a rate faster than the first component by an amount sufficient to substantially eliminate backlash in the gear train by a time the first and second components reach a common process speed. The first and second profiles may be adapted such that the mathematical integral of the time area between curves defining the profiles substantially matches the backlash amount.

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： A motion control system for controlling the motion of an intermediate transfer member in an image forming apparatus is provided in which a measuring member directly contacts the intermediate transfer member and generates signals proportional to the surface motion of the member. The measured surface motion is provided as a feedback signal to a motor controller, which compares the feedback signal with a reference signal. The difference between the signals is used to adjust the control of the drive motor for the intermediate transfer member drive roller in order to maintain a constant velocity for the intermediate transfer member.
