The active inking
system (1) is attached to the payout module (25) of self-service ATMs. It involves a modification of the top cover (4) of the cassette (24) by drilling three top holes (5) and one front hole (6). The top holes (5) are used to attach the ink scattering unit (2), and the front hole (6) accommodates the male quick-release
fastener (13) through which the ink (29) enters. The
system (1) includes a spark sensor (14), a mounting structure (12), a male quick-release
fastener (13), ink reservoir cylinders (15), screws (16), ink outlet connections (20), a drive trigger (17), CO2 gas cylinders (18),
compressed air tubes (19), and
compressed air connections (21). The ink scattering unit (2) includes a tank (10) that is aligned with the front hole (6) of the top cover (4) of the cassette (24).The tank (10) is connected to the scattering tube (8), which is provided with openings (9) through which ink (29) is sprayed onto the banknotes (7) to mark them. The sparks (27) activate the spark sensor (14), which actuates the drive trigger (17), breaks the seal (28) of the CO2
gas cylinder (18), pressurizes the
compressed air tubes (19), moves the front (22) and rear (23) pistons, and pushes the ink (29).
