Abstract:
1. A printing system, comprising: a substrate transport system that transports a substrate through the printing system; a decurler system comprising a penetrating member and an idler member, a surface of the idler member being conductive, the decurler system being configured to impart curl in the substrate; a power supply that provides an electrical power to the decurler system, the power supply being connected to the penetrating member; a drive system comprising a motor and a cam system, the cam system being operably configured to step the idler member from a home position at which an electrical current flowing through the idler member and the penetrating member is discontinued, until the idler member reaches a contact position at which the electrical current flows through the idler member and the penetrating member, the cam system being powered by the motor; and a controller, the controller being configured to count a number of steps required to step the idler member to the contact position during initialization to determine how many steps to move the idler member for decurling at the contacting position.
