10.4.1.2 Power Supply Route in the Reader Unit
0019-0027
iR3225 / iR3225N / iR3235 / iR3235N / iR3245 / iR3245N
In the reader controller PCB, 24V DC power which is supplied from the printer unit is used to drive motors and to turn on the LED of the CCD unit (generated by
the LED driver PCB). 12V DC power is also supplied from the printer unit, and the following DC voltages are generated.
-5V DC: Document size detection sensor
-3.3V DC: IC drive/copyboard cover open/close sensor, CCD unit HP sensor
Furthermore, 1.8V DC power is generated from 3.3V DC power, and is used for ASIC drive.
