Chapter 2 Setup Connecting the Cash Drawer • Do not connect both the optional external buzzer and the cash drawer to the printer at the same time by using a branched connector. • When the optional external buzzer is enabled with the memory switch (customized values) (see "Software Settings" on page 50), a cash drawer cannot be used. Be sure to disable it when you use a cash drawer. • Two driver transistors cannot be energized simultaneously. • Leave intervals longer than 4 times the drawer driving pulse when sending it continuously. Required specifications of cash drawers Specifications of drawers differ depending on makers or models. When you use a drawer other than specified, make sure its specification meets the following conditions. Otherwise, devices may be damaged. • The load, such as a drawer kick solenoid, must be connected between pins 4 and 2 or pins 4 and 5 of the drawer kick connector. • When the drawer open/close signal is used, a switch must be provided between drawer kick connector pins 3 and 6. • The resistance of the load, such as a drawer kick solenoid, must be 24 Ω or more or the input current must be 1A or less. • Be sure to use the 24V power output on drawer kick connector pin 4 for driving the equipment.
