Abstract
A printhead carriage for an ink jet printer having a plurality of printhead stalls therein and a printhead holddown cover having spring biased printhead holddown plungers on the underside of the cover and equal volume fluid passageways in the cover for conducting fluid from fluid inlets on said cover exposed to atmosphere to printheads in the stalls. An arcuately moveable air pump is engageable with one of a number of arcuately positioned inlets to the passageways in the carriage cover to enable a single pump to selectively apply positive pressure to prime each of the printheads in a desired sequence.
