Abstract
A reservoir assembly for use in an imaging device, the reservoir assembly includes an ink input port configured to receive liquid ink from an ink source and an ink tank configured to receive ink from the input port. A filter is positioned between the input port and the ink tank configured to filter ink received via the input port prior to reaching the ink tank. The reservoir assembly includes a foam reducing path configured to guide ink that passes through the filter to the ink tank, the foam reducing path having a varying cross-sectional size and/or shape configured to collapse, compress, stretch, and/or shear air bubbles in foam that passes through the filter prior to reaching the ink tank.
