Abstract
A skew detection arrangement comprises first and second series of targets movable past respective sensors, and monitoring means operable to monitor the outputs of the sensors, wherein the monitoring means is operable upon sensing that an output of a first one of the sensors is in a transition state to determine, from a transition direction of the transition state and an output of the other of the sensors, whether a skew condition has arisen. A skew detection method is also disclosed.
