Patent ID: 7798631

Claim:
A printer comprising: a print drum for receiving ink ejected by a print head; a release agent applicator located proximate to the print drum to apply release agent to the print drum; a transfix roller located proximate to the print drum; a displaceable linkage mechanically coupled to the transfix roller to move the transfix roller into and out of contact with the print drum; a controller electrically coupled to the displaceable linkage, the controller being configured to generate electrical signals that cause the displaceable linkage to move the transfix roller, the electrical signals generated by the controller including a transfix signal, a roll-off signal, and a release signal and the controller being further configured to terminate the roll-off signal in response to the transfix roller rotating a predetermined distance; and the displaceable linkage responds to the transfix signal to move the transfix roller to form a transfix nip with the print drum and exert a first pressure on the print drum, the displaceable linkage responds to the roll-off signal to move the transfix roller away from the print drum by a predetermined distance that enables the transfix roller to remain in rolling contact with the print drum and to exert a second pressure on the print drum that is less than the first pressure, and the displaceable linkage responds to the release signal to move the transfix roller out of rolling contact with the print drum.
