ABSTRACT:
An air knife pressure calibration system and method for a bottom vacuum corrugation recirculating document feeder includes measuring the air pressure and adjusting an air pressure control valve of the air knife to a predetermined value. This valve position is stored in a non-volatile memory and can be used to create a table of values for various document stack heights by adding constant values that represent additional documents to the one document value. Thus, customized valve positions are accomplished that are machine as well as altitude sensitive.
