4036-501 Scanner Principles of Operation Scanner Power The power cord carries AC line voltage to the external low voltage power supply (LVPS). The LVPS converts the 120/220VAC to regulated 5VDC, +12VDC, and +24VDC voltages. The LVPS sends these voltages to the main power switch in the Multifunction Device (MFD) controller cage. The voltage is then sent to the power distribution board. The +5VDC and +24VDC voltages are sent through the image processing board and onto the scanner through the 120 pin scanner cable. The voltage travels from the scanner cable into the scanner system board where it uses these voltages to run internal logic sensors, clutches, and the main motor assembly. General Information 1-23

Scanner Principles of Operation
Scanner Power
The power cord carries AC line voltage to the external low voltage power supply (LVPS).
The LVPS converts the 120/220VAC to regulated 5VDC, +12VDC, and +24VDC voltages.
The LVPS sends these voltages to the main power switch in the Multifunction Device
(MFD) controller cage. The voltage is then sent to the power distribution board. The
+5VDC and +24VDC voltages are sent through the image processing board and onto the
scanner through the 120 pin scanner cable. The voltage travels from the scanner cable
into the scanner system board where it uses these voltages to run internal logic sensors,
clutches, and the main motor assembly.
