System and method for improved registration performance

A receiver registration mechanism for aligning a receiver moving along a transport path relative to an image-bearing member moving at an image-bearing member speed, the receiver registration mechanism comprising:

• an encoder operative to track the movement of the image-bearing member;
• a roller assembly rotatable about an axis;
• a motor operative to drive the roller assembly to advance the receiver along the transport path;
• and
• the motor being driven in accordance with an output from the encoder to ramp the receiver from a stop to a velocity substantially equal to the image-bearing member speed.
