Abstract
A tray for a fluid-jet printing device for starting fluid-jet streams issuing from an orifice plate in a direction substantially perpendicular to the orifice plate. The tray includes an elongated box-like structure movable between various positions, including a sealing position below the orifice plate for drawing a vacuum through the orifice plate and facilitating flow of fluid from a plenum chamber above the orifice plate through the orifice plate for start-up. The tray is provided with backlighting such that, upon movement of the tray into a second position, the fluid streams issuing from the orifice plate may be visually observed against the backlighting to ensure proper start-up. Thereafter, the tray is moved to subsequent positions enabling location of the charging and deflection electrodes and droplet catcher structure below the orifice plate, as well as the substrate on which the printing will be effected.
