Abstract
An indirect printer includes a system for alternating the pressure in a transfer nip by manipulating the transfer roller. The system includes a pair of pivotable collars mounted about the ends of the transfer roller. The collars are pivoted towards or away from one another to bend the transfer roller and to increase or decrease, respectively, the pressure in the longitudinal center of the nip.
