<p>In an ink jet printer, a printhead assembly comprising a printhead (1) and an ink reservoir (4) is mounted on a scanning carriage for movement across a recording medium. During printing, droplets of ink are expelled from ink channels within the printhead and the channels are replenished with ink which is drawn in from the reservoir. The reservoir is connected to an ink source from which ink is supplied during printing and when the printhead assembly is being primed. A partition (9) within the reservoir ensures that, during priming, air can be expelled from the reservoir through the ink channels, thereby avoiding the need for an air vent from the reservoir. <IMAGE></p> |
