Summary: | A dryer for use in an aqueous ink printer adequately dries coated substrates printed with aqueous ink images before discharge of the substrates. The dryer has a housing, a plurality of laser diodes, a current source, a variable electrical resistance network having a plurality of resistors, and a controller. The controller is configured to identify a plurality of ink coverage densities for a plurality of areas in an ink image that passes through the dryer, select and vary an electrical resistance of one or more of the resistors in the variable electrical resistance network using the identified ink coverage densities, and operate the plurality of resistors in the variable electrical resistance network to connect the laser diodes in the dryer selectively to the current source through the plurality of resistors using the identified ink coverage densities and a speed of the substrate through the dryer. |
