A closed loop feedback method that continuously adjusts the lateral and
skew position of a sheet includes a first sensor that is used to measure
lateral sheet edge position. A second sensor measures the lateral sheet
edge position at a certain distance from the first sensor. Sheet skew
values can thus be calculated. Lateral and skew controllers provide
outputs to lateral and skew actuators, respectively, to adjust the sheet
position. A different method of registering sheets laterally and in skew
enables active sheet deskew without translating the sheet in the
cross-process direction. A sensor carriage position is controlled to find
the sheet edge after which deskew control can start. The average value of
the carriage position can then be fed in a feedforward manner to move the
image location to match the average paper position. This achieves good
average lateral registration and active skew control at a reduced cost.
