Abstract
Systems and methods for selectively powering multiple microwave energy sources in a dryer of a printing system. One embodiment is a microwave dryer that includes microwave energy sources configured to generate electromagnetic energy to dry a wet colorant applied to a continuous-form print media by a printer. The microwave dryer also includes waveguides configured to transport the electromagnetic energy. The waveguides include a passageway to pass the print media through the waveguides as the print media travels along a media path. A long axis of each the waveguides are positioned in a direction along the media path, and each waveguide is coupled to a different microwave source to section the electromagnetic energy into regions that are distinct from one another in a direction across the media path. The microwave dryer further includes a controller configured to regulate a power output for each of the microwave energy sources.
