First Claim
Patent Images
1. A jet printer, comprising:
- a first jet printing nozzle;
a first deflection element located proximate a first portion of an output trajectory of the first jet printing nozzle and being positioned to deflect printing fluid drops exiting the first jet printing nozzle in a first direction; and
a second deflection element located proximate a second portion of the output trajectory of the first jet printing nozzle that is further downstream from the first jet printing nozzle than the first portion, wherein the second deflection element is positioned to again deflect the printing fluid drops in a second direction different from the first direction, and wherein the first and second directions have at least their primary components in a same plane.

Abstract
Disclosed is a jet printing method, which includes firing printing fluid drops and deflecting them. The drops are then deflected again in a second direction, which can allow them to be deposited in a collimated swath. Also disclosed is dynamically adjusting the deflection to achieve a dynamic swath density and/or a dynamic swath width.
