Cash Drawer Requirements
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 ohms 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.

 The optional external buzzer and the cash drawer cannot be used simultaneously. Do not
connect both the optional external buzzer and the cash drawer to the printer at the same time
by using a branched connector.
 The cash drawer cannot be used If the enable/disable setting for the optional external buzzer is
set to “enable”. When using the cash drawer, be sure to set it to “disable” using the Epson TM-
T81III Utility.
 Two driver transistors cannot be energized simultaneously.
