This voltage is used to drive Printer Head
solenoid.
The Zener Diode (D41,27V) sets a Reference
Voltage, and +25VDC voltage is obtained by the
Power Tr.(TIP142,Q17). This voltage drives the
Printer and the Cash Drawer Solenoid.

Logic IC Driving Voltage: +5V
+5VDC Logic Driving Voltage is produced by the
of Q15 by switching Q15(A1010) using input
voltage ( +25V DC) . This makes D42(IN5822,Free
flowing) and L14 store Energy
and the Voltage is
smoothed by C57(470uF) and then +5V Logic
Voltage is produced .

Battery Voltage : +3.6Vdc
VCC is supplied to SRAM and the Clock IC
Chip when the power is off.
+12V DC is produced from volatge regulator
