No. | VOLTAGE | DESCRIPTION |
1 | +24VDC | Cash Drawer Solenoid Driving / Step Motor Voltage |
2 | +5VDC | Logic IC Driving Voltage / Sensor |
1) Drawer Driving and Feed, Auto Cutter Motor Voltage : +24Vdc
+24VDC is supplied from SMPS. This Voltage is smoothed by capacitors (C1,6,39).
This voltage is used as a Printer Head, Printer Motor, Cash Drawer Solenoid Driving voltage and a source voltage of the +5V voltage sources.
2) Logic IC Driving Voltage: +5V
+5Vdc Logic driving voltage is produced by the
