7-5. Peripheral Unit Drive Circuit

The Control Board of this printer is equipped with a circuit for driving peripheral units (Paper Cutter, Take-Up Device, Cash Drawer, etc.)

The 6P Modular Jack is used as the Drive Circuit. When using this circuit, connect the peripheral unit cable to the 6P Modular Jack (cable is not included). Note: Peripheral unit drive circuit connector only connects to peripheral units

such as cash drawers, etc.Do not connect it to a telephone. 1. Drive Circuit

Note: Make sure that the metal structural parts of the peripheral device are connected to frame Ground (Pin 1) to provide a static drain path.

2. Control code

Codes for Drive Circuit control are ESC BEL n1 n2, BEL, FS and SUB. Refer to the Control Codes in Section 5.

7-6. Error Condition Alarm Mode

If an error condition is detected during operation, the printer will stop printing and cause the ERROR signal to go Low. All solenoids & motors will be de- energized. It is necessary to turn the printer power off and on again in order to recover from the alarm mode.
