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.

The printer can detect the following error conditions: a. Motor Lock

b. Defective timing detector

c. Micro-processor out of program sequence
