The offered Canon 3000 Inktank Open Box includes faster speed and more accurate dot placement. This has thin film piezo actuators, which act as pumps that fire droplets of ink, are just 1 micron thick, and can precisely control the droplet shape and volume per nozzle, up to 50,000 times per second. In addition, by increasing the length of the nozzle plate, and thus the length of the nozzle line, from 1 inch to 1.33 inches, Canon 3000 Inktank Open Box can deliver professional output quality at incredibly high speeds with unbeatable image quality.
