A variable acceleration TAR. The properties and dimensions of the sheets in a stack are entered by a user or determined automatically. Since it is known from either customer provided input or automatic sensing what sheet length and resulting pitch size are feeding from any tray, the acceleration profile for the TAR is customized according to how much time is available to bring the sheet to transport speed in a given pitch zone. For longer sheet length with higher mass, there is also more acceleration time available and can reduce the required acceleration to a value that the motor and drive nip friction can handle thereby keeping motor size down and making more efficient use of the available torque of the motor with no added cost.

A metering pump system having a human interface device that is selectively mounted to a pump base. In an embodiment of the invention, sensors are provided that monitor characteristics corresponding to the material being pumped, and provide information about those characteristics to a computer which alters pumping parameters based on the characteristics.

The present invention is useful in a nip-forming apparatus including a first roll and a second roll, wherein one of the rolls is displaceable toward the other to control the position of the first roll relative to the second roll, and wherein one of rolls is driven and the other is rotatable. The invention defines a setup procedure that includes rotating the driven roll and sensing a rotational speed of the rotatable roll. While the driven roll is rotating, the displaceable roll is displaced to a home displacement position relative to the other roll, wherein the home displacement position corresponds to a displaced position of the displaceable roll where the rotatable roll rotates at a select speed in response to contact with the driven roll. This home displacement position is then recorded. The invention is particularly well-suited for setup of a sheet decurler in an image forming apparatus.
