Abstract: A method for controlling a printer includes receiving a set of first variables for the printer, determining, using a machine-learning program, one or more second variables based on the set of first variables, and controlling a printer to perform a print job based on the set of first variables and the one or more second variables. The first and second variables may correspond to different types of printer settings. The machine-learning program may determine the second variables using a classifier model that may prevent partial curing or drying, print media deformation and/or other defects.

Abstract: A printer includes a print zone, a curing zone, first and second fans, a heat exchanger, a heat valve, and a fan controlling unit. The print zone includes a print head to lay down ink on a media. The curing zone treats the media. The first fan generates a primary flow through the curing zone to treat the media. The heat exchanger is downstream the curing zone on the primary flow to condensate vapors contained in the primary flow. The second fan generate as secondary flow through the heat exchanger to cool the primary flow. The secondary flow is able to reach the print zone. The heat valve releases the secondary flow into the environment, downstream the heat exchanger. The fan controlling unit controls the second fan taking into account an ink density of the ink laid down on the media and/or an aperture level of the heat valve.
