The SCX-483xFR/563xFR/573xFW Electrical Circuit System consists of the following:
• Main Controller
• OPE Controller
• DDR2 SODIMM(Option)
• WLAN Module(only SCX-573xFW)
• SCF(Option)
• SMPS
• HVPS
Diagram of the SCX-483xFR/563xFR/573xFW Electrical Circuit
The Main Controller controls all modules required to print, that is, LSU, HVPS, SMPS, FAN, Fuser, etc.
The Main Controller receives print data from the host through network or USB Port. It takes this information
and generates printable video bitmap data. Engine and Video Controller are not separated.
