*1: Included in HP LaserJet 4 emulation.
*2: EPSON GL/2 mode, which emulates the GL/2 mode in the HP LaserJet 4 emulation, has 2
modes; LJ4-GL2 mode and GL-like mode.
❏ LJ4-GL2 mode: Used to print with software that supports the HP 7600 series electrostatic
plotter. It emulates GL/2 mode in the HP LaserJet 4 emulation. In EPSON
GL/2 mode, however, the operator can reach some parameters with
SelecType, without sending commands.
❏ GL-like mode: Used to print with software that supports the HP7475A series pen plotter.
GL-like mode features all the commands for LJ4-GL/2 mode, except some
instructions such as plotter unit and picture frame, that are the same as in
EPSON GL/2 mode. However, since GL-like mode doesn’t support some
commands used in the HP GL mode, print cannot be assured with
application software that specifies those commands.
See Table 1-11 for differences between LJ4-GL/2 mode and the GL-like mode.

Signal descriptions
DTR
Signal output by the printer. When the DTR signal is HIGH, the printer can
receive the RXD signal. When the SelecType settings do not specify DTR
control, the signal level remains HIGH while printer power is on. When
SelecType is used for DTR control, DTR goes LOW for any error condition.
Data (RXD) from the host computer must be stopped within 128 characters
after DTR goes LOW.
CTS
Always ignored.
TXD
Serial ASCII data output by the printer. It remains in MARK state (LOW
level) between transmitted character codes. Logic 0 is at HIGH level
(SPACE), and logic 1 is at LOW level (MARK).
GND
Connected to the printer chassis. The printer chassis GND and signal GND
are connected to each other.
RXD
Serial ASCII data input to the printer. It maintains the MARK state (LOW
level) between received character codes.

Rev. A
EPL-N2000 Service Manual
Product Description
TTY-TXD
Current loop signal:
HIGH impedance (SPACE) between pins 17 and 24 or X-ON signal
sent across pins 17 and 24 indicates that the printer is ready to
accept data; LOW impedance (MARK) or X-OFF signal sent
indicates that the printer is busy.
TTY-RXD Return
Current loop signal: Current return for pin 17.
TTY-TXD Return
Current loop signal: Input data current loop.
TTY-RXD
Current loop signal: Current return to pin 25.
Protocol
There are two types of protocols, as listed below, and each of them can be designated by the
SelecType independently.
❒
DTR/DSR protocol
The DTR/DSR control protocol can be selected by SelecType. The DTR signal is set to a HIGH level
when the printer is ready to receive data, and to LOW when an error is detected. DTR remains
HIGH when SelecType is set to OFF for DTR control. The printer sends only TXD off when the DSR
signal is HIGH. (DSR signal is always assumed HIGH when select mode for DSR is set to OFF.
X-ON/X-OFF transmission is independent of DSR.
❒
X-ON/X-OFF (DC1/DC3) protocol
Select mode is used to execute X-ON/X-OFF protocol. The X-OFF (DC3) code, transmitted by error
detection, warns the host computer to stop sending data within 128 characters. No further X-OFF
codes are sent in response to additional data sent from the host computer after the warning has
been given once. An X-ON code is transmitted when all the errors are cleared. The X-OFF code is
transmitted only once when the remaining capacity of receiving buffer drops under for 128
characters, or any error occurs. The X-ON code is sent when the printer is powered on. The
SelecType setting can be used to withhold X-ON/X-OFF code transmission.

1.4.2 Panel Settings
This printer has two panel setting modes: One Touch mode*1 and the SelecType mode. One Touch
mode is more limited but easier to use. This mode has direct access to specified items in the menu
tree*2, while the SelecType mode has to follow the fully branched out menu tree to reach a
parameter. Therefore, descriptions for One Touch mode have been eliminated in this section. Once
new settings are registered on EEPROM, they are not changed until the printer is turned off. See
Table 1-20 for SelecType options.

Product Description
1.4.6 Controller RAM Status
RAM on the controller of this printer uses dynamic memory allocation to make the best use of the
memory. Therefore, no portion is rigidly allocated for user-defined settings such as font download,
form overlay, and buffer size, and the total amount of memory available changes depending on
new values.
When data exceeds memory capacity during a process, the error message Mem Overflow appears
on the LCD. In this case, more memory needs to be added. You can occasionally prevent the error
by decreasing memory buffer size.
1.4.7 EJL (Epson Job Control Language)
This printer supports EPSON’s original EJL. This system allows users to access printer setting
modes through commands sent by the computer. This mode is especially beneficial to users who
operate printers through the network.
1.4.8 BiRITech (Bi Resolution Improvement Technology)
This printer has BiRITech, which is used to smooth out jagged edges of lines or shapes. The
resolution, with this technology, has been improved to control dot formation in the main scan at
approximately 1200 dpi, and it provides printing of a high quality.
Note:
Using BiRITech may possibly cause print quality to deteriorate with meshed patterns or
special graphic images. You can avoid this by setting BiRITech to OFF in SelecType.

1.4.9 PGI (Photo and Graphics Improvement )
PGI enhances the print quality of halftones and tone gradations, generally used in photographic
and graphic images. Compared with conventional systems, which use one white or black dot as the
minimum unit, PGI technology divides a single dot into 3 parts for a more precise image.
Therefore, the amount of data required for this technology is twice as large as the previous method.
1.4.10 Toner Saver Mode
Toner saver mode can cut toner consumption to half normal use. The printer saves toner by
substituting a gray shade, formed with reduced dots, for the black inside characters. The upper and
right edges are reinforced with full black lines. Use of this mode, however, is limited to output that
does not require good print quality.

1.4.11 Precaution for Power Off
This printer has an EEPROM installed on the main controller to store user default settings . If the
printer is turned off while the printer is writing new data to the EEPROM, that new data will be
lost, and this may cause an error the next time the printer is powered on. To avoid this, do not turn
off the printer until the message Ready is indicated on the LCD.

2.1.1 Printing Process
The whole printing process for this printer is divided into the seven stages described in Table 2-1.
Table 2-1. Printing Process for the EPL-N2000
Steps
Process
Description
1
Charging
Charges the surface of the PC drum with static electricity.
A rayon brush is used.
2
Exposure
The laser beam emitted from the laser unit produces an
electrostatic latent image on the surface of the PC drum.
3
Development
Toner is fed through the sleeve roller to the surface of the PC
drum to produce a visible toner image.
Transfer
The transfer roller transfers the toner image from the surface
of the PC drum onto the paper, using an electrical charge
applied from the transfer roller.
5
Separating
The electrode discharges the paper to separate it from the
drum.
6
Fusing
Toner image is fixed on the paper with heat and pressure.
7
Cleaning
The cleaning blade clears toner off the PC drum and transfer
roller.

In the exposure process, the laser unit emits laser beams onto the PC drum surface to create an
electrostatic latent image. There is a polygon mirror installed inside the laser unit. The mirror,
which is rotated by the scanner motor, reflects laser beams from the laser diode toward the drum,
on which the laser beams run, scanning from one edge to the other. There is a sensor called SOS, or
Start Of Scan, sensor attached in the laser unit. The laser beam is emitted onto the sensor to detect
the starting point for scanning of each line. It correctly times the illumination of the laser diode
with the rotation of the polygon mirror.

2.1.1.3 Developing Process
Paper goes through this process to convert electrostatic image produced through the charging and
exposure processes into visible image. It is accomplished using toner and 3 bias voltages;
developingt bias, toner bias, and seal bias. Developing bias feeds toner evenly on the sleeve roller.
The amount of toner fed onto the roller is controlled by developing bias, which enables the printer
to adjust printing tones.

2.1.1.4 Transfer Process
In the transfer system, toner image created on the PC drum through the developing process is
transferred to the paper. The roller transfer system is used for this printer.
When the paper goes through the PC drum and the transfer roller, the roller provides the paper
with positive voltage applied from the high voltage unit. Then, the toner image on the drum
transfers to the paper being attracted by the positive voltage. The needle pole located above the
roller is used to collect the remaining static electricity on the paper.

2.1.1.5 Fusing Process
The fusing unit permanently fixes the toner image, transferred from the PC drum, onto the paper.
The fusing system this printer uses is the heat roller fusing system. The toner on the paper is
melted by the upper fusing roller, which is heated by the heater lamp, then the toner is fixed by
pressure from the paper traveling through the upper and lower fusing rollers.
There is a thermostat and thermistor installed on the upper fusing roller.The thermistor detects the
surface temperature of the upper fusing roller. The PWB-A board switches the heater lamp on or
off, depending on the temperature detected. When the temperature is abnormally high, which is
usually caused by a malfunction of the control board or the thermistor, the thermostat detects it
and cuts off the current.
During warm up, the heater continues to heat up until it reaches 190oC (374 F). At printing, the
heater is controlled to remain 180oC (356 F).

2.1.1.6 Cleaning Process
Toner remaining on the PC drum after transfer process is scraped off with the cleaning blade,
placed in close contact with the surface of the PC drum. The toner that has been scraped off is
collected back into the toner collection box inside the Imaging cartridge.
2.1.2 Engine Mechanism Operation
This section describes the major units in the engine and their mechanisms.
2.1.2.1 Fusing Unit
❏
Upper fusing roller
A metallic sleeve roller that melts the toner on the paper. It is heated by a heater lamp built
internally.
❏
Lower fusing roller
A silicon rubber roller that applies pressure to the paper for fusing the toner to the page.
❏
Heater lamp
A lamp built into the upper fusing roller. This is supplied AC power to heat the upper fusing
roller.
❏
Thermistor
The thermistor, located next to the upper fusing roller, detects the roller’s surface temperature.
To control the roller’s temperature, the control circuit alternately switches the heater lamp on
and off based on the temperature the thermistor detects. (This process continues occurring as
long as the thermostat does not detect overheating.)
❏
Thermostat
When the thermistor fails to control the temperature, the thermostat takes over the job. The
thermostat has a series connection to the heater lamp’s power source line, and when the
temperature rises to the specific level, it opens the contact point. Then current is cut off as a
consequence.

2.1.2.2 Paper Feeding Mechanism
❏
Multi Purpose Tray
The drive for the tray is transmitted to the push-down cam by way of the main motor, paper
takeup clutch, and paper takeup roller. The paper takeup roller and push-down cam rotate
once when the the paper takeup solenoid is energized. While turning, the push-down cam
pushes down the stack of paper on the paper lifting plate. Then the paper takeup roller picks
up a sheet of paper. Friction between the paper separator and transport roller avoid multiple
paper feeding.

Operating Principles
Lower Cassette Tray
The drive for the lower cassette tray is transmitted from the printer to the transport roller via
the transmission gear, paper takeup clutch, and paper takeup roller. The lower paper cassette
unit is controlled by the engine control board (PWB-A) through control board PWB-C. When
the paper takeup solenoid (SL2) is energized, the paper takeup roller rotates once to pick up a
sheet of paper, and the transport roller carries it to the PC drum. The separator avoides
multiple paper feeding.
The paper size switch on control board (PWB-C) detects the size of the paper loaded in the
tray. The paper near-empty sensor detects 2 conditions: whether the amount of paper
remaining in the tray is 50 sheets or less or whether it is 250 sheets or less. The paper empty
sensor is used to detect paper empty condition.

Operating Principles
2.2.2.2 Video Controller Operation Principles
Print data and commands transmitted from the host computer through the network, parallel, or
optional I/F are read and then stored in the input buffer in DRAM. If the buffer size (which varies
depending on the SelecType setting) is increased, the host computer is released sooner.
Data and commands are then stored in the video RAM (the image buffer) memory area after being
processed in the video controller CPU, where the data is converted into print bitmap data (image
data). The size of the video RAM depends on the current size of the RAM memory and the
SelecType setting.
An error or warning for memory size occurs under the following conditions, and such problems
usually can be solved by changing buffer size or increasing RAM memory:
❏
Bitmap data from the CPU is too complicated for the size of video RAM.
❏
When data is complicated, the CPU cannot process it faster than it is transmitted to the
engine controller board.
Image data stored in video RAM is transmitted to the ASIC, where the BiRITech and PGI functions
manipulate the data. The data is then passed on to the engine controller as video data. The engine
controller processes the video data transmitted from the video controller. Engine mechanisms
driven by the PWB-A board then perform printing.
When an error occurs, the CPU in the engine controller detects it and sends status information to
the video controller, where the information is processed, and the corresponding error message and
the code are displayed on the Control panel.

3.1 GENERAL INFORMATION
This chapter describes the disassembly/assembly procedures to be used for replacing the main
assemblies of the EPL-N2000.
3.1.1 Precautions for Disassembly/Assembly
Follow the precautions below when disassembling/assembling the printer.
WARNING
❏ Disconnect the power cord before disassembling/assembling the printer.
❏ Be sure to handle the fusing unit carefully, because the unit remains hot for a while after
the printer stops printing.
❏ If it is necessary to plug in the power cord and operate the printer after disassembling it,
take the following precautions:
1.Keep your hands and clothing well away from operating or rotating parts (such as
rollers, fan motors, etc.)
2.Never touch electric terminals or high-voltage components (such as the charger and the
high voltage unit).
❏ Be sure to close the top cover when operating the printer. This printer uses an invisible
laser beam which could cause damage or loss of eyesight. Therefore never energize the
interlock switch to connect current with the top cover open.
CAUTION
❏ Handle frame edges with care since this printer has a considerable amount of metal
materials.
❏ Do not disassemble the Imaging cartridge.
❏ If the Imaging cartridge is removed from the printer, do not place it in direct sunlight.
❏ Do not disassemble the printhead assembly.
❏ To prevent damage to ICs from static electricity, do not touch the ICs on the circuit
board or the terminals of peripheral electrical components with your hands.
❏ Use only the recommended tools to ensure safe and efficient maintenance work.
Inappropriate tools may damage the machine.
❏ Never open the top cover until the main motor stops completely.
❏ When transporting the printer, remove the Imaging cartridge.
❏ When transporting the printer a long distance, pack it using the original packing
material.

5.1 OVERVIEW
Types of errors that may produce a similar symptom in a page printer, such as poor print quality or
abnormal operation, vary widely, making identification of failed parts and components more
difficult. To overcome such problems for this printer, this section describes troubleshooting
procedures using the printer’s built-in self-diagnostic function for easy and efficient repair.
5.2 SELF-DIAGNOSTIC FUNCTION
This printer’s control circuit is equipped with a self-diagnostic function that checks the operating
conditions for each component. If the printer detects an error that a user cannot recover from, the
printer displays the location and error code on the LCD panel. The message is as follows:
Service Req effff
In the message above, e represents the error type and ffff represents the error code. Errors are
divided into two categories: E and C.
❏ E: Related to the engine.
❏ C: Related to the controller.
Table 5-1 lists error types and error codes.

6.1 MAINTENANCE
This section gives information necessary for maintaining the printer in its optimum condition.
Appropriate maintenance after troubleshooting, as well as after the occasional replacement of worn
out units, is essential to prevent potential problems from occurring.
Maintenance items described in this section are divided into two subsections: user maintenance
and service maintenance (performed only by qualified repair personnel).
6.1.1 User Maintenance
Users can achieve maximum print quality from the printer by following the instructions in Table
6-1.

the total number of printed
pages exceeds the specified
maximum (Approximately
8,000 to 10,000 sheets).
6.1.2 Service Maintenance
The EPSON EPL-N2000 does not require any replacement of units at specified intervals. It is,
however, recommended that specific units be replaced after periods determined by the total
number of sheets printed. This is indispensable in preventing abnormal operations, such as
multi-sheet feeds, paper jams, and fusing malfunctions, which can be often caused by worn out
units. Refer to Table 6-2 for guidance.
Table 6-2. Instructions for Service Maintenance
Unit
Printable number of sheets
The fusing unit
Approximately 60,000 to120,000 sheets
The paper takeup roller assembly
Approximately 120,000 sheets
The transfer unit
Approximately 60,000 to 120,000 sheets
❏ If dirt sticks, use a moist cloth, and then clean with a dry cloth.
❏ Do not use solvents, such as thinner and alcohol.
❏ Never touch the surface of the transfer roller. When it needs cleaning, run blank prints
repeatedly. Otherwise, remove the transfer unit and blow off the dust using an air gun.
