Abstract
An apparatus and method for slowing down the ejection velocity of the print media into an output tray, without the use of active velocity control of the exit nip or interface, utilizing a non-circular drive roll running against a leaf spring. The regions of contact of the non-circular drive roll are driven at a velocity slower than the incoming sheet velocity, and the spaces between the regions of contact are used to enable relaxation of buckling generated in the print media (e.g. print sheets). The print media travels at the velocity of the upstream nips until they are entirely under the control of the non-circular drive roll exit nip, thus enabling the sheets to be ejected from the exit nip, at a slower velocity, improving stacking registration.
