OPERATING PRINCIPLES
CHAPTER
2
EPSON EPL-N4000/EPL-N4000+ Optional Finisher Stapler Revision A
2.1 Power Supply
The Power Supply of the Finisher Stapler is supplied by the 100V AC via the
printer and generated by the LVP PWB in the Finisher Stapler.
2.1.1 Control over the Finisher Stapler
LVPS sends the sensor data in the Finisher Stapler to the MCU of the printer.
Commands from the MCU of the printer is transferred to the Finisher PWB
and controls over respective components of the Finisher Stapler.
Figure 2-1. Components
Operating Principles Power Supply 15
EPSON EPL-N4000/EPL-N4000+ Optional Finisher Stapler Revision A
2.1.2 Control Main Parts of the Finisher Stapler
Finisher PWB
LVPS PWB sends sensor data in the Finisher Stapler to MCU of the
printer. Commands from the MCU of the base engine is transferred to
the Finisher PWB and controls over respective components of the
Finisher Stapler.
HCS Low Voltage Power Supply
Generates +5VDC and +24VDC from 100VAC.
Unload While Run Switch and LED
This switch is for user to interrupt Finisher Stapler when it is
proceeding its job.
LED flashes when interruption is made.
Finisher Interlock Sensor
Supervises that the door of the Finisher Stapler is not open.
Front Cover Interlock Switch
When Front Cover is open, shut off 24VDC.
Compiler Cover Safety Switch
When Compiler Cover is open, shut off 24VDC.
IOT Full Paper Sensor
Supervises the amount of paper on the eject tray of the printer.
Transport Exit Sensor
Supervises paper passing from Transport Assembly.
Transport Interlock Sensor
Supervises the condition of the Transport Cover.
Transport Motor
Drives Transport Rolls.
2.1.2.2 Compiler
Compiler arranges paper as set.
Tamper Motor
Drives Tamper which pushes paper to the end.
Tamper Home Sensor
Supervises the position of the Tamper.
Top Tray Safety Switch
Detects if there are any obstructions under the Top Tray and shut off
+24VDC and stop the Elevator Motor.
Middle Tray Safety Switch
Detects if there are any obstructions under the Middle Tray and shut
off +24VDC and stop the Elevator Motor. Top Tray Safety Switch and
Middle Tray Safety Switch are connected in series.
2.1.2.1 Transport
Shift paper from DDC to Compiler.
IN Gate Solenoid
Alternate the direction of IN Gate.
IN Gate Interlock Sensor
Supervises the position of IN Gate. (Up/Down)
Transport Entrance Sensor
Supervises paper passing to Transport Assembly.
Compiler Tray Up/Down Solenoid
Slant Compiler Tray when the amount of paper has reached twenty

DOC is at the exit of the Fuser of the printer. DOC includes IN Gate. When
Finisher Stapler is selected, the Finisher PWB drives the IN Gate Solenoid to
alternate the direction of the IN Gate and carries paper to the HCS Transport
Assembly.
