The Skywalker JA 128/50 jetting assembly has been
designed specifically to meet the exacting performance
requirements of high productivity, solvent based, wide
format graphics printing. A total of 128 individually
accessible channels are driven from a single
piezoelectric ceramic crystal, providing excellent
channel-to-channel uniformity. The nozzles are
arranged in a single line, at a 0.020-inch spacing, for
maximum interlace flexibility. The jetting assembly
design has been optimized for high dutycycle operation
up to 16 kHz. The high drop velocity and excellent jet
straightness minimize banding artifacts.
The Skywalker JA 128/50 jetting assembly is easy to
integrate into printer carriages. It incorporates an
integral mounting bezel molded out of a durable,
chemically inert engineering plastic. Registration
features enable easy alignment to the carriage frame.
The fluid interface is convenient and easy, through a
single female Luer Lock fitting. Two electrical
connectors at the top of jetting assembly allow each
channel to be individually addressed. An optional Driver
Chip Module reduces the electrical interface
requirements to two serial data streams and the high
voltage fire pulse used to actuate the pumping
chambers.
Numerous design features have been incorporated to
promote a long service life, including a robust stainless
steel nozzle plate and replaceable ink inlet filter. All
static sensitive electronics are located upstream of the
jetting assembly, minimizing the likelihood of electrical
failures. The fluid interface is positioned away from the
jetting assembly housing to reduce the possibility of
contaminating the electrical contacts |
