Safety Precautions
POWER SUPPLY AND ELECTRICAL COMPONENTS
Before starting any service procedure, turn off the printer and unplug the power cord from the wall outlet. If you must service the printer with the power applied, be aware of the potential for electrical shock and do all tasks by following the procedures in this manual.
W ARNING
Do not touch any electrified component unless you ar e instructed to do so by service procedure.
MECHANICAL COMPONENTS
LASER ASSEMBLY
If you service a driving assembly (e.g., gears), first turn off the power and unplug the power cord. Then manually rotate the assembly.
W ARNING
Do not try to manually rotate or stop the drive assemblies while the Main Motor is running.
W ARNING
This printer uses a laser as part of the pri nting process. The laser beam is a very powerful, straight, narrow beam of light that produces extreme heat at its focal point. The laser beam in this printer is invisible. Although you cannot see the beam, it can still cause severe damage. Direct eye exposure to the laser beam may cause eye injury or blindness.
Never place a mirror or a reflective tool or object in the laser beam path.
To avoid permanent eye damage, follow these directions;
Before starting any service procedure, swi tch off the printer
power and unplug the power cord from the wall outlet.
Do not disassemble the ROS Assembly or any laser component
that displays a Laser Warning Sticker.
Use caution when you are working around the ROS Assembly or
when you are performing laser related repair procedures.
Do not disassemble the printer in such a way that the laser
beam can exit the printer engine during a print cycle.
Safety Components
Make sure fuses, interlock switches, covers and panels are all functioning properly after you have reinstalled or replaced them.
Warning/Caution Labels
WARNING and CAUTION labels are stuck on dangerous parts in the printer to make you aware of the potential dangers that are present when you are working with those parts.

Components and life
Note)*
Toner life is estimated based on continuous printing on A4 size
with 5% print coverage. Toner life will vary according to print
coverage and printing method (continuous or intermittent, print
density, toner-save mode, etc.).
**
This rotation corresponds to approximately 45000 sheets printing at A4 continuous printing(landscape setting). This OPC
drum life is indicated by minute(s) calculated from the turn on
the engine status sheet.
How to distinguish
Method to distinguish: ID on the cartridgeType: Check OEM maker and if it is for Japan or for abroad.
1.2.11 Configuration
In the EPL-N4000 controller the following setti ngs can be configured according to the market destination. The setti ngs are made with jumper resistors, and must thus be set at the factory.

LED LIGHTS
On Line LED(green):On = Printer is ready for printing.
Off = Printer is not ready.

Off = No effective recei ved data is left in the printer. But if the control code is not ended, LED is still On. Blinking = Processing the data.
Error(red): Error happens and it can be canceled by
Continue switch.
“One-Touch” Setting Mode 1 LED (green):
On = indicates that “One-Touch” setting mode 1 is selected. 4 items can be set; Paper Source, Selection, Paper size, Manual Feed, and Orientation.
“One- Touch” Setting Mode 2 LED (green)
On = indicates that “One-Touch” setting mode 2 is selected. 4 items can be set ; RITec h, Copi es, MP Tray paper size and Toner Save Mode.
Select Type Mode LED(green)
On = indicates that the printer is in the select type panel setting mode.
SWITCHES
On-line: The printer goes to by pressing this button when the
printer is in the on-l ine(ready) status. Pressing th is butt on during the panel setting, the printer escapes from the panel setting mode and immediately goes to the On­line(ready) mode.
Data(yellow): On = Received data is not printed out and still left
in the printer. But if the received data except effective printing data is left, LED does not turn on.

EPSON EPL-N4000 Chapter 1 Product Description
CAUTION
Form Feed:If Data light is On in the not-ready condition, the
printer prints the received data on the one sheet by pressing this button. If the plural numbers of printing is selected, the printer prints out that number. In case of the data which the control code has not ended yet, the printer prints out the data, which has already received. However, if the data light is off, the printer does not eject the paper.
This printer has EEPROM and hard disk drive HDD
inside and records various setting values and printing data. If the printer is turned off during this process, writing operation is not guaranteed, and error occurs when the printer is turned on next time. Therefore, never turn off the printer at the following cases;
Continue: Error is canceled by pressing this button, while the
Continue LED light is on. When warning occurs, warning indication is canceled by pressing this button.
Select type/Alt switch:Ordinary condition, One-touch setti ng mode1,

From the power on to On-line light on.
On-line light is blinking
When the printer is printing(when the paper
transporting motor is in active)
When you want to stop printing, press “On-line
switch” or perform Job Cancel/Reset.
Menu switch: The printer goes to the setting mode by
pressing this switch.
Each switch operation for the panel setting is on the next page.
Item switch: The printer goes to the previous setting item
by pressing this switch.
Value selection switch:The printer goes to the previous setting item
by pressing this switch.
Enter switch: By pressing this button, the printer goes to
status sheet in the test printing menu.
Reset(Continue): The printer stops printing or resets by
pressing Alt and Continue switches. After displaying “Reset” on the display, pressing both switches for 5 seconds lead to “Reset All” and executes warm boot.
