FIELD: generation of copies of documents by means of module jet devices and systems. SUBSTANCE: module printing mechanisms in accordance with invention are designed for use with compatible module mechanism for printing copies of documents and device producing copies. There is provided separation of jet device for generation of copies of documents according to liquid elements and electron units. Module separation of mechanism of copies of document from printing mechanism gives possibility of replacement of printing module that contains all key elements of jet printing system based on requirement to technical aids of printing systems. In particular there are meant those elements which show highest tendency to aging or failure in the course of time as result of frequent usage or actions of end user. Subsystem of printing mechanism includes one or more printing modules having elements of printing head with accompanying elements for collection and distribution of printing inks and mechanisms controlling flow of ink and pressure, one or more containers for printing ink, constant, refilled or replaceable with one or more compositions of printing ink, one or more aids feeding printing inks, such as tubes and valves connecting containers with printing inks. This approach ensures achievement of number of advantages peculiar to both jet devices with one-time ink reservoirs and to jet devices possessing ink reservoirs placed outside of carriage of printing device. EFFECT: increased efficiency of generation of copies of documents. 24 cl, 21 dwg
