Abstract:
1. A method of maintaining side 1 to side 2 registration during duplex imaging on paper in an ink jet printing system, comprising: printing a side printing a side providing a single full width image on web array sensor; capturing a side determining difference between measured and desired spacing in process and cross process directions in response to signals from said full width image on web array sensor; adjusting head delays and positions to achieve desired registration; beginning a print job; printing side printing side capturing side determining difference between measured and desired spacing in process and cross process directions in response to signals from said full width image on web array sensor; adjusting head delays and positions to maintain desired registration, and repeating said registration pattern and determining the difference between measured and desired spacing in process and cross process directions and making appropriate head delays and position adjustments during said print job to maintain desired registration.
