Summary: | A tandem printing system for imaging a media web includes a first and second print engines. A controller identifies a change in a position over time of a bottom of the media web in a loop box that is placed in the media path between the first and second print engines. The controller identifies an effective diameter of a drive roller in one of the print engines with reference to the change in position of the bottom of the media web. The controller modifies a rotational velocity of the drive roller with reference to the effective diameter to maintain velocity of the media web at a predetermined level and control a position of the bottom of the media web in the loop box. |
