3.7 HEAD DETECTION CIRCUIT   

 
VP is controlled so as to prevent the head from electrolytic etching.   
When turning ON the VP, set 11VC (Pin 4) of the gate array (CBM-202LA)to "HIGH".     
When turning it OFF, set the HVC to "LOW".   
 
It  is  also  provided  with  a  temperature  detection  circuit  which  serves  to  prevent  print  quality  from  being 
deteriorated or destroyed by temperature.    This function, through use of a thermistor installed in the printer, 
detects  temperature  based  on  which  energy  applied  to  the  head  is  determined.    Further,  when  head 
temperature has exceeded 60

℃

, printing is stopped so that the head is protected from being destroyed.   

 
For  protection  of  CPU  runaway,  make  connection  so  that  the  gate  array  is  reset  by  output  of  the  CPU 
watchdog timer.    The CPU itself has been set to which resetting can work.    Further, to prevent  the  head 
strobe from being turned ON at that time, place a pull-up resistance in STRB1 to STRB3 each by one.
