A technique includes rotating a squeegee roller to regulate a film thickness of ink on a developer roller; and using the developer roller to transfer a portion of the ink from the developer roller to a photoconductive member. The technique includes creating, by an electrode, a potential bias with the developer roller to transfer the ink to the developer roller; and inhibiting flow streaks on the developer roller, where inhibiting the flow streaks includes restricting a flow of ink between the squeegee roller and the electrode.

Inhibiting ink flow streaks

Provided in one example is an articulating housing for carriage assembly of a printer system, the articulating housing comprising an articulating housing coupling part for establishing an articulated coupling between the articulating housing and the carriage assembly, as well as a carriage assembly and a printer system comprising such an articulating housing.

Housing for a carriage assembly

A print agent supply unit includes: an inlet chamber to distribute print agent within the print agent supply unit; a valve to selectively permit print agent into the inlet chamber, the valve including: a print agent inlet opening; and a valve member to selectively close the print agent inlet opening, the valve member being tapered towards an upstream end of the valve member.
