Abstract
An ink-jet hard copy apparatus provides a flow of air across the printing surface of a sheet of print media during printing operations. The airflow scrubs the boundary layer of the printing surface such that paper cockle is reduced by resultant improvement in drying time. A writing instrument deflector is used to prevent substantial interference with ink droplet flight trajectories due to positive airflow through the print zone.
