Sheet separation, feeding and printing with reduced image deletions of various types of print media sheets from a stack thereof, especially coated print media sheets with high humidity adhesion difficulties, is assisted by a sheet air puffer for a sheet separator/feeder having an automatically variably heated air supply. This may be accomplished by electronically obtaining information on the selected type of print media sheets to be fed from the sheet separator/feeder, and the ambient conditions, including at least the humidity, and by combining that information in an electronic look-up table additionally provided with set points to produce a control signal for variable air puffer temperature and strength.
