ABSTRACT:
A priming device for a printbar having an array of print dies employs a vacuum nozzle shorter in width than one print die. At least one wet wiper blade is located adjacent to the vacuum nozzle and is used not only to moisten and wipe the channel outlets of the printbar, but during application of vacuum pressure in priming, the wiper blade serves to block the flow of air into adjacent channels, thereby eliminating cross-talk between groups of channels.
