Abstract:
1. A method of correcting for misregistration of images printed on a receiver sheet resulting from multiple transfers during simplex imaging comprising: a. establishing one or more actual positions of the receiver sheet relative to a primary imaging member by one or more of determining a position of an in-track front edge of a receiver sheet traveling on a paper path through a printer using a sensor, determining a position of an in-track rear edge of the receiver sheet with a second sensor, and determining a position of one of a cross track edges with a third sensor array; b. establishing a look up table (LUT), including content representing an actual position of the receiver sheet; c. comparing one or more measured positions with the LUT content representing reference positions; d. determining a correction factor from a difference between reference positions and measured positions of one or more of the in-track front and rear and the cross track positions; e. adjusting a position of an electrostatic latent image on the primary imaging member by varying a writer output to compensate for the correction factor and; wherein the method is implemented by one or more controllers for updating the LUT.
