2.3.5 Printer Unit

The facsimile machine has a bubble ink jet system which uses a special head and

prints on plain paper.

The bubble ink jet print head consists of an interchangeable cartridge, which contains

a sponge soaked with liquid ink, which is ejected from 50 nozzles made of a nickel and

gold component, under the control of the signals that reach an electrical circuit

consisting of 50 resistors (Fig. 2-13).

Each nozzle generates a drop of ink

when the corresponding resistor is pow-

ered (+24 Volt) for a few microseconds.

The resistor is heated and the ink that is

in direct contact with it evaporates, ex-

panding like a bubble and pressing the rest

of the ink against the nozzle.
