Abstract
Systems and methods are provided for balancing air flow in dryers of printing systems. The dryer includes a heating element, top flow generator, and bottom flow generator. The heating element is within the dryer, and heats a web of printed media. The top flow generator directly projects a first jet of gas onto a top side of the web. The first jet of gas deflects air proximate to the web. The bottom flow generator directly projects a second jet of gas onto an opposing side of the web. The second jet strikes the web at substantially the same location as the first jet, and compensates orthogonal force applied to the web by the first jet. Furthermore, the top and bottom flow generators are both oriented to project the jets partially in the direction of travel of the web.
