ABSTRACT:
A multi-chamber inkjet print head includes a plurality of individual print head ink chambers that share a common ink filter and are in fluid communication with an ink flow regulator. An associated method of assembling a print head base having at least two separate fluid conduit paths filtered by a single piece of filter includes the steps of: (a) positioning a single piece filter between at least two separate ink receptacles associated with a print head and at least two respective ink conduits; and (b) sealing at least two separate ink paths between the at least two separate ink receptacles associated with the print head and the at least two ink conduits, such that the single piece of filter is in concurrent fluid communication with the at least two separate ink paths.
