A dental light comprises at least one light emitting diode light source configured to produce a light beam and at least one collimating lens system situated to receive the light beam. The collimating lens system is configured to collect and collimate the light beam. The collimating lens system can additionally modify the beam through controlled diffusion or shape the beam using an aperture.

A curved wiper blade system is provided for an inkjet printing mechanism to remove ink residue from an inkjet printhead installed in the printing mechanism, here, ill as an inkjet printer. A pair of wiper blades each curve inwardly toward each other, and maintain this curvature during bi-directional wiping strokes. This configuration allows one wiper blade to receive an ink solvent from an applicator and apply the solvent to the ink-ejecting nozzles of the printhead when moving in one wiping direction. When wiping in the opposite direction, one wiper blade also removes ink residue from an interconnect portion of the printhead, as well as from the ink-ejecting orifice plate portion of the printhead.

Curved wiper blade system for inkjet printheads

A curved wiper blade system is provided for an inkjet printing mechanism to remove ink residue from an inkjet printhead installed in the printing mechanism, here, illustrated as an inkjet printer. A pair of wiper blades each curve inwardly toward each other, and maintain this curvature during bi-directional wiping strokes. This configuration allows one wiper blade to receive an ink solvent from an applicator and apply the solvent to the ink-ejecting nozzles of the printhead when moving in one wiping direction. When wiping in the opposite direction, one wiper blade also removes ink residue from an interconnect portion of the printhead, as well as from the ink-ejecting orifice plate portion of the printhead.

An angular wiping system is provided for removing ink residue from an inkjet printhead installed in an inkjet printing mechanism. By canting a wiper blade in opposite directions as the blade moves through a bi-directional wiping stroke, a nozzle portion of the ink-ejecting orifice plate is wiped on both passes of the blade. A pair of non-ink-ejecting side cheeks of the orifice plate laying on opposite sides of the nozzle portion are each wiped once during the bi-directional wiping stroke, with one cheek being wiped while the blade travels in a first direction, and the other cheek being wiped when the blade travels in a direction opposite to the first direction. An inkjet printing mechanism having the angular wiping system and method of wiping using this system are also provided.
