A system and method that enables web paper skew detection by monitoring print head motor position. An inline full width array sensor (138) actively tracks the alignment of the print heads (110-124) across the print zone and actively moves the heads to maintain alignment. If the paper (126) starts to skew across the print zone, a color misregistration error will be detected and the print units will be moved with respect to each other to maintain alignment. The absolute position of the print heads can be monitored by tracking the steps sent to each motor to maintain alignment. |
