Abstract

An inkjet printhead assembly includes a manifold assembly and a print chip. The manifold assembly includes an ink passage having an ink outlet and an air passage having an air outlet. The print chip is attached to part of the manifold assembly and is positioned for receiving ink from the ink outlet of the ink passage. The air outlet is offset from the print chip and is configured for delivering a flow of air laterally across the print chip.

Claims (8)

1. An inkjet printhead assembly comprising:

a manifold assembly including an ink passage having an ink outlet and an air passage having an air outlet; and

at least one print chip attached to part of the manifold assembly, the print chip being positioned for receiving ink from the ink outlet of the ink passage,

wherein the air outlet is offset from the print chip and is configured for delivering a flow of air laterally across the print chip.

2. The inkjet printhead assembly of claim 1 , wherein the air passage is connected to a supply of pressurized air.

3. The inkjet printhead assembly of claim 1 , wherein the ink passage is connected to a supply of ink.

4. The inkjet printhead assembly of claim 1 , wherein the print chip is positioned at an oblique angle with respect to a longitudinal axis of the printhead assembly.

5. The inkjet printhead assembly of claim 1 comprising a plurality of print chips, the print chips being positioned to allow physical overlap when butted in a line.
