ELECTRICAL MODULES
Fan IOT: Expels the air inside the printer and introduces
fresh air into the printer to prevent an excessive
rise of the inside temperature.
HPS: Has the Main Power Switch, Interlock Switch,
Sensor Re
g
istration, Sensor Pre-Re
g
istration,
Sensor No Paper, LVPS (Low Volta
g
e Power
Supply) circuit, and HVPS (Hi
g
h Volta
g
e Power
Supply) circuit on it. The HPS also has the
switchin
g
circuit to switch on and off AC power
to the Heater Lamp of the Fuser Unit.
Interlock Switch:
Opens the 24 VDC circuit from the LVPS to the
controller when the Cover Assembly Exit is
open.
LVPS:
Produces re
g
ulated low DC volta
g
es (5V
supplied to lo
g
ic circuits, 5V-LD supplied to the
Laser Diode, and 24V supplied to motors,
solenoids, and clutches) from the AC power.
HVPS:
Produces hi
g
h AC and DC volta
g
es used for
char
g
e (BCR), development (Ma
g
net Roll),
transfer (BTR), and detack (Detack Saw) in the
print process.
C258MAIN Board: This is a main control circuit of the EPL-N1600
and contains two major circuits: ima
g
e
processin
g
main control circuit and MCU
(Machine Control Unit) which directly controls all
printer operations respondin
g
to si
g
nals from the
main control circuit.
