ABSTRACT:
An ink drying apparatus for an ink jet printer includes an internal heating apparatus. The heating apparatus comprises gas flow restrictors for air that enters the heating apparatus. The gas flow restrictors may be formed as dual horizontal slots which are sized to maintain a higher air pressure in the heating apparatus as compared to the air pressure in a region within the ink drying apparatus that is outside of the heating apparatus.
