Abstract: A printing device has an image receptor adapted to have an image formed thereon. The printing device also includes a transfer roller and a motor. A transfer roller load mechanism moves the transfer roller into contact with the image receptor in response to the motor output. A controller manipulates the motor in conjunction with a feedback signal from a load detector and regulates the load of the transfer roller.

Abstract: An optical encoder that includes an optical grating and a quadrature optical encoder sensor that move relative to each other. The optical grating includes a first encoder bar and a plurality of second encoder bars, wherein the first encoder bar is optically configured to change an amplitude of an output of the quadrature optical encoder sensor.

Abstract: Disclosed are methods for compensating for failed ink jets in an ink jet apparatus. The method in embodiments determines if one or more ink jets are nonfunctioning or have failed and substitutes for the one or more nonfunctioning ink jets by using one or more operational ink jets. The operational ink jets used are neighboring operational ink jets that fill in for the one or more failed ink jets. The one or more failed ink jets are disabled wherein a primary image pass is performed followed by one or more additional imaging passes to fill in for the one or more disabled ink jets by enabling the one or more neighboring operational ink jets. The additional imaging passes may be a right fill imaging pass, a left fill imaging pass or a combination of both.
