Abstract: An apparatus and method for advancing a receiver into registered relationship with a moving image-bearing member. A motor is provided that is responsive to motor drive pulses. A drive member engages the receiver, and a drive coupling connects the drive member and the motor. An encoder generates encoder pulses that correspond with movement of the image-bearing member. A pulse generator generates motor drive pulses in response to the encoder pulses to accelerate the receiver to a speed approximately equal to the speed of the image-bearing member speed. A timer determines an amount of delay time between detection of the receiver by an in-track sensor and the beginning of a subsequent movement of the motor. A delay mechanism delays the acceleration of the receiver to the image-bearing member speed by the amount of delay time.

Abstract: An apparatus and method for moving a receiver into a registered relationship with a moving image-bearing member in a registration mechanism. The apparatus and method account for receivers that arrive at the registration mechanism outside a normal operating time window. When a receiver arrives too late, the receiver is accelerated to a speed greater than that of the moving image-bearing member for a period of time sufficient to account for the arrival delay. The receiver is then decelerated to a speed substantially equal to that of the image-bearing member. When a receiver arrives too early, the receiver is brought to a stop for a period of time sufficient to account for the early arrival. The receiver is then accelerated to the image-bearing member speed.

Abstract: A sheet feeder having a platform for supporting a stack of sheets, a feed head assembly for feeding sheets seriatim from the top of a sheet supply stack on the platform, a mechanism for moving the platform relative to the feed head assembly, and a device for controlling operation of the platform moving mechanism. The control device for the platform moving mechanism includes a sensor for detecting marginal edges of sheets in the sheet stack on the platform, and producing a signal indicative of sheet edge detection. Additionally, a sensor is provided for detecting the location of the topmost sheet on the sheet stack on the platform, and producing a signal indicative of such top sheet location detection. A signal is set representative of the top of the sheet stack being in proper operative relation to the feed head assembly, this set signal being based on the signal from the top location sensor for the particular location of the top of the stack when the marginal sheet edge detection signal is first produced. Periodically thereafter, a control signal is produced for actuating the sheet stack supporting platform moving mechanism until the signal indicative of detection of the topmost sheet from the top location sensor is substantially equal to the set signal.
