Abstract

A printhead having a drop generator for creating print and non-print drops and a drop deflector for causing the trajectories of the print drops and the non-print drops to diverge includes a liquid extraction channel for removing liquid from the gas flow duct; the liquid extraction channel having an entrance which opens off from the gas flow duct; an outlet; a catcher for collecting the non-print drops wherein the catcher has an ink return channel; at least one via connecting the ink return channel to the liquid extraction channel; and wherein a portion of the liquid passing through the ink return channel of the catcher flows through the at least one via into the liquid extraction channel and from the liquid extraction channel out the outlet.

Claims (16)

1. A printhead having a drop generator for creating print and non-print drops and a drop deflector for causing the trajectories of the print drops and the non-print drops to diverge comprising:

a liquid extraction channel for removing liquid from a gas flow duct;

the liquid extraction channel having an entrance which opens off from the gas flow duct;

an outlet;

a catcher for collecting the non-print drops wherein the catcher has an ink return channel;

at least one via connecting the ink return channel to the liquid extraction channel; and

wherein a portion of the liquid passing through the ink return channel of the catcher flows through the at least one via into the liquid extraction channel and from the liquid extraction channel out the outlet.

2. The printhead of claim 1 wherein the entrance has a reduced channel height compared to non-entrance portion of the liquid extraction channel.

3. The printhead of claim 1 wherein the liquid extraction channel funnels into two funnels.

4. The printhead of claim 1 wherein the via connects to a small flow channel that branches off from the liquid return channel of the catcher.

5. A printhead having a drop generator for creating print and non-print drops and a drop deflection mechanism for causing the trajectories of the print drops and the non-print drops to diverge comprising:

a liquid extraction channel for removing liquid from a gas flow duct wherein the liquid extraction channel has an entrance which opens off from the gas flow duct;

an outlet from the liquid extractor channel;

a catcher for collecting the non-print drops wherein the catcher having an ink return channel; and

wherein the liquid extraction channel funnels into two funnels.

6. The printhead of claim 5 wherein the entrance has reduced channel height compared to non-entrance portion of the liquid extraction channel.
