1. An apparatus comprising:
a first feed element to receive a web;
a second feed element to receive the web from the first feed element;
an actuator to simultaneously move the first feed and the second feed elements; and
a controller to control the actuator to move the first feed element and the second feed element when the web exiting the second feed element is shifted from an intended position,
wherein the controller is to control the actuator to move the first feed element a first distance and to move the second feed element a second distance different from the first distance to compensate for the shift in the web exiting the second feed element, and
wherein the actuator is to move the first feed element at a first rate and the second feed element at a second rate different from the first rate, so that the first feed element reaches the first distance concurrently with the second feed element reaching the second distance.
