ABSTRACT:
An adaptive method for handling media is provided for an inkjet printing mechanism having a printhead that prints on media in a printzone. A drive motor, a spacing adjuster, a controller storing a tolerance adjust value, and a media support member are provided, with the support member defining a printhead-to-media spacing in the printzone. The tolerance value is summed with a value selected for the type of media or image to determine a total motor drive value. In a coupling step, the motor is operatively coupled to the support member using the spacing adjuster. Following the coupling step, in an adjusting step, the printhead-to-media spacing is selectively adjusted by the driving spacing adjuster with the motor for the total drive value. A method is provided of accommodating manufacturing tolerance variations accumulated during assembly of an inkjet printing mechanism having a printhead that prints on media in a printzone.
