Patent ID: 8810617

Claim:
A method for determining and adjusting the pressure to a printhead during a print operation, comprising: providing a printhead support housing operable for placement in a print station of a printer, said printhead support housing further comprising; a motor housed within the printhead support housing and being operable for driving a plurality of synchronized rotating gears, said gears being mounted about threaded posts wherein said threaded posts are configured to cause said gears to compress or decompress a set of biasing mechanisms mounted below said gears and connected to said printhead; and a sensor unit operable for monitoring the thickness of a print media and in communication with a control circuit operable for adjusting the printhead pressure to correspond to pre-defined levels, wherein said control circuit receives a signal from said sensor unit based on the thickness of the print media and further sends a signal to said motor to rotate said synchronized gears to compress or decompress said biasing mechanisms attached to said printhead and thereby adjusting the pressure against the print media.
