Abstract
A paper conditioner to control image dependent curl in a copier/printer includes a nip formed between metering and transfer rolls with grooves positioned on end portions of both of the metering and transfer rolls. Portions of both the metering and transfer rolls are located over a sump connected to a reservoir that supplies liquid to the nip for transfer to the transfer roll. The grooves act as gutters and allow excess liquid to flow into a sump, and subsequently, back into the reservoir. Flaps are positioning in the grooves in order to aid in the flow of fluid back into the sump.
