Patent ID: 7931362

Claim:
A printer for forming an image on media, said printer comprising: a frame; an image receiving member secured to the frame for rotation about a longitudinal axis; a print head configured to eject ink onto the image receiving member to form an image on the image receiving member; a transfix roller having a first end and a second end, said transfix roller being configured for movement with respect to the image receiving member to form selectively a nip between the transfix roller and the image receiving member; a feeder configured to advance media into the nip; a motor having an output shaft; a translational member having a first end and a second end, one of the first and the second ends of the translational member being mechanically coupled to the output shaft of the motor to enable the motor output shaft to move the translational member in a linear path; a hydraulic translator operatively connected to the other end of the translational member to enable movement of the translational member in the linear path to displace hydraulic fluid within the hydraulic translator and move a pair of links in a linear direction, the first and the second ends of the transfix roller being mechanically coupled to the pair of links to enable the displacement of the hydraulic fluid within the hydraulic translator to move the transfix roller in the linear direction for movement towards and away from the image receiving member; and a controller electrically coupled to the motor, the controller being configured to send a motor control signal to the motor to control a direction and speed of the motor output shaft.
