Description:
• The Spectra SL-128 AA is a highly compact and light-weight jetting assembly designed specifically for ink jet applications requiring multiple Printheads packed tightly together.
• These modules are ideal for fast moving, high performance printer carriage designs. General compatibility with a wide range of fluids makes the SL-128 AA jetting assembly extremely versatile.
• Two electrically independent piezoelectric slices, each with 64 addressable channels, are combined to provide a total of 128 jets. The nozzles are arranged in a single line, at a 0.020 inch distance between nozzles. Resolutions up to 450 dpi are possible.
• This jetting assembly contains serial-to-parallel converters for selecting which jets to fire; all jets can be fired simultaneously or individually. By using an optional Head Interface Board, image data can be daisy-chained into one serial stream to reduce the data interface hardware requirements. A high voltage fire pulse with controlled slew rates is used to actuate the pumping chambers within each channel.
• The fluid interface and electrical connection are at the top of the jetting assembly and several mounting configurations are possible. This arrangement permits for extremely tight packing in the print process direction. The dual ported fluid interface facilitates flushing for quick change-overs and for displacing drying fluids with inert fluids during periods of non-use.
• Optional temperature control components are available for precise control of fluid viscosity. Optional deaeration hardware can be provided.
