7-5. Peripheral Unit Drive Circuit
The Control Board of this printer is equipped with a circuit for driving periph-
eral units (Paper Cutter, take-Up Device, Cash Drawer, etc.)
The 6P Modular Jack is used as the Drive Circuit. When using this circuit, con-
nect 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.

Note: Make sure that the metal structural parts of the peripheral device are con-
nected 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 print-
ing 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.
The printer can detect the following error conditions:
a. Motor lock
b. Defective timing detector
c. Micro-processor out of program sequence
