Abstract
A jet drop printing head comprises a transportable upper assembly and a lower assembly adapted for receiving the upper assembly in such a manner as to control the alignment between the two assemblies. The upper assembly, which is primarily a fluidics package, carries an orifice plate and fluidic elements for producing a jet-forming flow of printing liquid through a series of orifices in the orifice plate. There is also a fluidics system which minimizes accumulation of coagulated ink and includes a double diaphragm having a valving diaphragm which works against the raised lip of a conduit insert and a control diaphragm which works against a valve closing spring.
