Abstract
A method for servicing an inkjet printhead without removing the printhead from a carriage of the printer, wherein a controlled pressure differential is generated across the nozzle plate of the printhead to cause the formation of a controlled puddle of ink on the outside of the nozzle plate. Ink is then fired into the puddle through the nozzles of the printhead. The puddle may then be drawn back into the printhead through the nozzles. Alternatively the puddle is generated, is maintained for a predetermined period of time and then is withdrawn into the printhead without ink being fired from the nozzles.
