8.10.3 DC power supply configuration
The printer is equipped with two power supply units with single output. The two power supply
units are connected to the printer power inlet via the printer power switch on the printer's rear.
Turning on the printer power switch starts supply of AC power to the power supply units, which
outputs 24 V DC and 38 V DC.
The above-mentioned 24 V DC and 38 V DC power are first input to the ACT3 board, converted
into proper voltage, and then supplied to each unit. For details, see the power supply schematic
diagram and the table on the second page of the diagram.
The following table lists the main DC power supplies on the boards and their destinations. Note
that even the same voltage supplied from the same board may be divided into two or more lines.
For details, see the power supply schematic diagram in the appendix.
