Referring to the figure, a movable carriage type priming station 10 has a supply of air directed to the station by line 12, which is emitted into the interior of the priming station perpendicular to the ink jet channels 14 and immediately in front of the printhead face 16. Retrieval of the ink and/or ink droplets 18 during priming is accomplished by a vacuum system (not shown) via conduit 20 to the priming station, so that the ink is drawn from the printhead. For pagewidth printers 22, the priming station is moved across the full length of the printhead assembly as shown by arrow 24 on demand or automatically for maintenance and priming via guide rails (not shown) and drive cable 26.
