P45~P47 are output pins from MCU, which control the Power-on, Feed and Error LEDs
respectively. The LED lights on when the signal is “low”, goes out when the signal is
“on”.
P72: the detect pin of push button.(normally at ‘high’ level)
P60: the detect pin of feed button. (normally at ‘high’ level)
P65: the detect pin of the peel-off sensor. (normally at ‘high’ level)
P62: the detect pin of the ribbon sensor. (normally at ‘high’ level)
P63: the detect pin of the black mark sensor. (normally at ‘high’ level)
P64: the detect pin of the gap sensor and print head micro sensor. (normally at ‘high’
level)
