Abstract
Printhead priming can, in various examples, employ a conduit and a divider such that a predetermined portion of a pressurized gas in the conduit is provided to an environment surrounding the divider and a remaining portion of the pressurized gas in the conduit is provided to a printhead at a pressure sufficient to prime an ink supply.
Claims15
A system, comprising:
- a conduit coupled to a printhead, where the conduit includes an inlet and an outlet;
- and
- a divider that divides a pressurized gas flowing through the conduit such that a predetermined portion of the pressurized gas is provided to an environment surrounding the divider and a remaining portion of the pressurized gas in the conduit is provided via the outlet of the conduit to the printhead at a pressure sufficient to prime an ink supply of the printhead.
A system, comprising:
- a pump;
- a conduit including an inlet and an outlet, where the inlet is coupled to the pump;
- and
- a divider that couples the conduit to a printhead and divides pressurized gas flowing from the pump through the conduit to the printhead such that a portion of the pressurized gas in the conduit is provided to an environment surrounding the divider and a remaining portion of the pressurized gas in the conduit is provided via the outlet of the conduit to the printhead at a predetermined pressure sufficient to prime an ink supply of the printhead.

A method to prime a printhead, comprising
- supplying pressurized gas from a pressure source to an inlet of a conduit;
- providing, via an orifice of a passive divider, a predetermined portion of the pressurized gas in the conduit to an ambient environment surrounding the divider;
- and
- providing a remaining portion of the pressurized gas in the conduit to an ink supply at a predetermined pressure sufficient to prime the ink supply.
