2.3 Electrical Circuit Operating Principles
This section describes the operating principles of C687 main board and C687 PSB
board.
The electric circuit of Stylus C110/C120/D120 consists of the following boards.
 Main Board
 C687 main board
 Power Supply Board
 C687 PSB/PSE board
 Panel Board
 C687 PNL board
NOTE: CPU and ASIC is integrated as one chip (IC8) on the Main Board.
2.3.1 Power Supply Board
The PSB/PSE board of Stylus C110/C120/D120 employs the simulated oscillating
stimulation flyback converter circuit method, and it supplies +42VDC to the drive line.
The application of the output voltage is described below.
AC voltage input from AC inlet first goes through filter circuit that removes high
frequency components and is then converted to DC voltage via the rectifier circuit and
the smoothing circuit. DC voltage is then lead to the switching circuit and FET QF1
preforms the switching operation. By the switching operation of the primary circuit,
+42VDC is generated and stabilized at the secondary circuit.

Voltage Application
+42VDC
• Motors (CR Motor, PF Motor)
• Printhead drive voltage
• Printhead nozzle selector 42V drive voltage
