This printer has the following functions to help cope with abnormal operation:

• Monitors the head drive circuit on the VP 1 (+35 VDC) line, and cuts the voltage if an abnormality ' is detected.

• Interlock for the VP3 (+35 VDC) carriage motor common line

• Monitors the VP3 (+35 VDC) line, and cuts the voltage if any voltage fluctuation is detected.
