Notes:
*1: Mechanism selection signal and the printing enable signal for 3" mechanism.
*2: Not used at the combination with 2" mechanism.
*3: At the mechanism side, this pin number is for the printing data 2.
Since this pin number is used for the printing data 1 at the inter face board, the No. 15 and No. 17 pins are
connected.
*4: This signal is used for the adjustment of printing duty depending upon the rank of thermal head resistor. Not
used at this interface board.
• Symbol "— —" means a negative logic signal.
• "I" or "O" means a signal direction from the interface board side.
