2.2 Electrical Circuit Operating Principles

The electric circuit of the Stylus PHOTO 2000P consists of the following:

Control circuit board: C304MAIN

Power supply board: C298PSB/PSE

Panel board:

C304PNL

Refer to Figure 2-11 for the major connection of the boards and their
roles.

Figure 2-11. Electric Circuit of Stylus PHOTO 2000P

2.2.1 C298PSB/PSE Board

The power supply board for the Stylus PHOTO 2000P is C298PSB/PSE. It
uses a RCC switching regulator system, and su42VDC and +5VDC
to the printer mechanism and control board.

2.2.1.1 Electrical Circuit

The table below shows the voltages produced in this circuit and their
applications.

Table 2-16. Application of the DC Voltages

NOTE:

The 5VDC is only applied to the parts and locations shown in the
table above. The C304MAIN uses 3.3V drive chips for most of the
logic-line chips (CPU, ASIC, ROM, DRAM). For this reason, those
chips are not driven by the +5VDC produced by the but power supply
board but the 3.3VDC that is reduced by the 3.3VDC regulator on the
C298PSB/PSE.
