5.7.1 Q. Drawer kick does not operate properly.
5.7.1.1 A. Drawer specifications differ, depending on the manufacturer and the part
number.
We recommend to use a Drawer that is made by EPSON. These conditions also apply to any
other devices that use the drawer kick-out connector. Any devices that do not satisfy all the
following conditions must not be used.
[Conditions]
• A load must be provided between drawer kick-out connector pins 4 and 2 or between
pins 4 and 5. (*1)
• When the drawer open/close signal is used, a switch must be provided between drawer
kick-out connector pins 3 and 6. (*2)
• The resistance of the load must be 24 W or more, or the input current must be 1 A or less.
(*3)
• Be sure to use drawer kick-out connector pin 4 (24 V power output) to drive the device.
Never connect any other power supply to the drawer kick-out connector. (*4)
NOTES:
(*1) Operating the printer with incorrectly installed devices voids the warranty.
(*2) Connecting devices other than the drawer open/close switch voids the warranty.
(*3) If a device with a resistance of less than 24 Ω or an input current of over 1 A is used, the resulting overcurrent
may damage the device.
(*4) Connecting a power supply other than that specified voids the warranty.

to send this data.
Dim Send_ data(0) As Byte
Send_data(0) = &h81 ’1 byte of sending data
MSComm1.Output = Send_data
