Patent ID: 7815105

Claim:
At least one computer readable medium including computer executable instructions operative to cause at least one computer of an automated banking machine which includes a cash dispenser, an inkjet printer including a plurality of nozzles, and a humidity sensor, wherein the inkjet printer and the humidity sensor are in operative connection with the at least one computer, and wherein the machine is operative to carry out at least some transactions during which the inkjet printer operates to print indicia on items, wherein the at least one computer is operative to cause the inkjet printer to operate at other times than when printing indicia on items during transactions, wherein during each respective other times the inkjet printer is operative to expel ink using a respective nozzle firing energy levels that differs from a nozzle firing energy level that would have been used had printing of indicia occurred at the respective other time, wherein the nozzle firing energy level is adjusted by changing the applied potential to the firing nozzle, and using a respective firing frequency level that differs from a nozzle firing frequency level that would have been used had printing of indicia occurred at the respective other time, to carry out a method comprising: (a) determining through operation of the at least one computer based on humidity sensed with the humidity sensor, a change in humidity; (b) responsive at least in part to the determining in (a), determining through operation of the at least one computer, an operating nozzle firing frequency level and an operating nozzle faring energy level to be used with the humidity sensed; (c) responsive at least in part to the determining in (b), adjusting at least one of a current nozzle firing frequency level and a current nozzle firing energy level to result in the operating nozzle firing frequency level and the operating nozzle firing energy level determined in (b); and (d) subsequent to the adjusting in (c), causing through operation of the at least one computer, the inkjet printer at a time other than when printing indicia on an item during a transaction, to expel ink using the operating nozzle firing frequency level and the operating nozzle firing energy level.
