Connecting the Cash Drawer
Use a cash drawer handled by EPSON or your dealer.
Connecting the Drawer Kick-out Cable
Connect the connector of the drawer kick-out cable to the printer.
• 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 buzzer is set to "Enabled" with the memory switch (see "Setting the
Memory Switches/Receipt Enhancement" on page 43), a cash drawer cannot be used.
Be sure to set it to “Disabled“ when you use a cash drawer.
WARNING
• 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-out solenoid, must be connected between pins 4 and
2 or pins 4 and 5 of the drawer kick-out connector.
∗ When the drawer open/close signal is used, a switch must be provided between
drawer kick-out connector pins 3 and 6.
∗ The resistance of the load, such as a drawer kick-out 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 out connector pin 4 for driving the
equipment.
• Use a shield cable for the drawer connector cable.
• Two driver transistors cannot be energized simultaneously.
• Leave intervals longer than 4 times the drawer driving pulse when sending it
continuously.
• Do not insert a telephone line into the drawer kick-out connector.
Doing so may damage the telephone line or printer.
