 During Transportation/Storage:

 Use the specified carton whenever moving or storing the PC

Drum.

 Note that replacement of a PWB may call for readjustments or

resetting of particular items.

HANDLING OF OTHER PARTS

 The magnet roller generates a strong magnetic field. Do not bring it

near a watch, floppy disk, magnetic card, or CRT tube.

 The storage temperature is in the range between -20°C and

+40°C.

 In summer, avoid leaving the PC Drum in a car for a long time.

 Handling:

 Ensure that the correct PC Drum is used.

 Whenever the PC Drum has been removed from the copier,

store it in its carton or protect it with a Drum Cloth.

 The PC Drum exhibits greatest light fatigue after being exposed

to strong light over an extended period of time. Never, therefore,
expose it to direct sunlight.

 Use care not to contaminate the surface of the PC Drum with oil-

base solvent, fingerprints, and other foreign matter.

 Do not scratch the surface of the PC Drum.

 Do not apply chemicals to the surface of the PC Drum.

 Do not attempt to wipe clean the surface of the PC Drum.

If, however, the surface is contaminated with fingerprints, clean it using
the following procedure.

1. Place the PC Drum into one half of its carton.

3. Soak a small amount of either ethyl alcohol
or isopropyl alcohol into a clean, unused
Dust-Free Cotton Pad which has been
folded over into quarters. Now, wipe the
surface of the PC Drum in one continuous
movement from its rear edge to its front
edge and off its surface one to two times.

2. Gently wipe the residual toner off the
surface of the PC Drum with a dry, Dust­Free Cotton Pad.

A.Turn the PC Drum so that the area of its

surface on which the line of toner left by the
Cleaning Blade is present is facing straight
up. Wipe the surface in one continuous
movement from the rear edge of the PC
Drum to the front edge and off the surface
of the PC Drum.

B. Turn the PC Drum slightly and wipe the

newly exposed surface area with a CLEAN
face of the Dust-Free Cotton Pad. Repeat
this procedure until the entire surface of the
PC Drum has been thoroughly cleaned.

*At this time, always use a CLEAN face of the dry
Dust-Free Cotton Pad until no toner is evident on
the face of the Pad after wiping.

*Never move the Pad back and forth.

4. Using the SAME face of the Pad, repeat the
procedure explained in the latter half of
step 3 until the entire surface of the PC
Drum has been wiped. Always OVERLAP
the areas when wiping. Two complete turns
of the PC Drum would be appropriate for
cleaning.

NOTE:

 Even when the PC Drum is only locally dirtied, wipe the entire

surface.

 Do not expose the PC Drum to direct sunlight. Clean it as

quickly as possible even under interior illumination.

 If dirt remains after cleaning, repeat the entire procedure from

the beginning one more time.

HANDLING OF THE IMAGING CARTRIDGE

* Only for Products Employing an Imaging Cartridge.

 During Transportation/Storage:

 The storage temperature is in the range between -20°C and

+40°C.

 In summer, avoid leaving the Imaging Cartridge in a car for a

long time.

 Handling:

 Store the Imaging Cartridge in a place that is not exposed to

direct sunlight.

 Precautionary Information on the PC Drum Inside the Imaging

Cartridge:

 Use care not to contaminate the surface of the PC Drum with oil-

base solvent, fingerprints, and other foreign matter.

 Do not scratch the surface of the PC Drum.

actual practice the device ID values are displayed as a continuous character string, and
no carriage return codes inserted.
The CMD parameters are not in order. CID, MODE, or STATUS parameters are not

The default device ID setting for EPL-5900L is as follows:

MFG:EPSON;CMD:ESCPAGES-01;MDL:EPL-5900L;CLS:PRINTER;DES:EPSON EPL-5900L

The controller board is equipped with a jumper switch “JP1” for selecting the parallel
interface's communication mode. If communication with the host is not possible for
some reason, JP1 can be set in the “Nibble” position, a mode where ECP
communication is not performed. (It is recommended that this jumper be set in the
“ECP” position during normal use.)

Nibble: In the Reverse mode, communication with the host is conducted in the

Nibble mode.

ECP: If the host supports ECP, communication with the host is conducted in the

ECP mode.

This switch is publicly disclosed to users.

MFG, MDL, DES and CID of Device ID are re-definable. (This must not be included
in the manual.) And the CID field does not respond with the default value, but responds
with the defined character string only when redefined.
Device ID when redefined is as follows. “xxxxx” is user-defined character string.

***1;
MFG:xxxxx;
CMD:PJL,EJL,ESCPL2, ESCP9,PRPXL24-01,PCL,HPGL2-01,ESCPAGE-04;PCLXL**

Product Description Controller Specification 33

EPSON EPL-5900/EPL-5900L Revision B

1.4.2.2 USB Interface

Supports Windows USB PnP.

Supports the 18-digit USB ID as follows:

**P++YYMMDDhhmmssR

**: A number of 00 to 99. Acquired for each model.

“07” for EPL-5900. “08” for EPL-5900L.

P: Identifier. Always “P” for page printers.

++: PC number of assembly line. (00~99)

YY: The year of assembled date. (lower two digits; 00~99)

MM: The month of assembled date. (01~12)

DD: The assembled date (01~31)

hh: Hour of assembled time. (00~23)

mm: Minute of assembled time. (00~59)

ss: Second of assembled time. (00~59)

R: Reserved and always “0” with EPL-5900/EPL-5900L.

Device ID in Printer Class conforms to 1.4.2.1 "Parallel Interface Specifications".

The USB ID written into the printer can be checked on the Status Sheet. (It is displayed
on the bottom left of the Status Sheet next to the ROM Version.)

If the circuit board is replaced, or other service performed, the USB ID may be changed
to another ID (this is because the USB ID is rewritten when the EEPROM storing the
USB ID is damaged or the circuit board is replaced).In this case, if a printer with the
USB ID changed is connected to the PC, it is recognized as a different printer, so the
PC requires the USB port driver to be installed again..

C A U T I O N

The USB ID is stored on EEPROM of the main board, and you have to
re-assign the ID when you replace the main board to new one in
repair.
Refer to Chapter 5 “Adjustment” for the details.

1.4.2.3 Type B Interface (Not Available with EPL-5900L)

1.5.3.1 Status Specifications (Model-dependent)

 Manual Feed Mode

This section describes only the standard specifications. Further specifications are
described in the Basic Operation Specifications for Page Printer.

<Outline>

Manual Feed mode is useful when users want to use a special type of paper for which
no paper feeder of the printer has not been set. For printing in this mode, the printer
displays Manual Feed mode and waits user's operation before executing Manual Feed
printing job. As the paper source, priority is given to the Manual feed slot.

<Specifications>

 Available languages: all

ESC/page, PS3, LJ4, PCLXL, ESCP2, FX, I239X and IPDS

 Unit of job in Manual Feed mode (unit of job controlled by Printqueue)

• Printing from Network: one job per connection

• The job is started by job start command of EJL/PJL.

• The job will be ended when the receiving time-out (Selectype setting) occurs.
(Connectionless type)

[Restriction]
If many data in Manual Feed mode are sent continuously on the conditions under
which distinction between jobs can not be made, the printer recognizes them as
one job. Then the printer does not display the Manual Feed mode at the beginning
of the 2nd data and thereafter sheets will be fed continuously.

NOTE:

When the following data, namely, Data 1 and Data 2, are sent to the
printer even on the same conditions as mentioned above under
which distinction between jobs can not be made, the printer
recognizes the mode correctly.
That is, when the data are sent in the order of Data 1 and Data 2,
the Data 2 will be printed in normal mode. When the data are sent
in the order of Data 2 and Data 1, the Data 1 will be printed in
Manual Feed mode.
Data 1: Page to be printed in Manual Feed mode
Data 2: Page to be printed in normal mode

 Operation

Before starting to print the first page of the job in Manual Feed mode, the printer
displays Manual Feed mode and wait user's pressing of the Start/Stop switch.

LCD display: Manual Feed XXXX: XXXX: Paper size

Pressing the Start/Stop switch starts printing of the job and prints all the pages
automatically.

NOTE:

Pressing the Start/Stop switch too long is invalid.

Once the Start/Stop switch has been pressed and paper feeding has started,
printing in Manual Feed mode is continued by feeding paper from the same
paper source until paper is used up. (The paper source does not change until
paper is used up.)

[Examples] During the same Manual Feed job, the paper source does not

change even in any of the following cases:

• Changing the Page Size or Paper Type

•Paper Jam

• Ready/Off Line

• In Manual Feed after Manual Feed is quit once

Once the Start/Stop switch has been pressed, Paper Set error does not occur
until the paper in the paper source is used up.

No check of paper size/paper
type

Priority is according to the
current auto mode specification
of Manual Feed mode.

Manual Feed mode is displayed
again

Product Description Control Panel 47

EPSON EPL-5900/EPL-5900L Revision B

Neither Check Paper Size error nor Check Paper Type occurs.

♦

When paper has been used up during printing

When the printer has run out of paper, it displays Manual Feed mode again.
And the subsequent operation will be the same as when it prints the first sheet
in Manual Feed mode.

♦

Printing of multiple copies

Printing of multiple copies is handled as one job in Manual Feed mode.
It is not necessary to press the Start/Stop switch at printing the first sheet of
each copy.

♦

When pages to be printed in Manual Feed mode and pages to be printed in
normal mode are mixed in one job

The printer displays Manual Feed mode and waits user's operation only before
printing the first page of the first copy in Manual Feed mode.
The printer does not stop to wait user's operation before printing the second
and subsequent copies in Manual Feed mode.
Paper source setting is effective in the job.

be fed from the paper source which was selected by user's
operation in the previous Manual Feed mode.

♦

In the case of double-sided printing

Printing is carried out in a mode selected for the first page.

♦

In the case of n-up printing (set by printer driver)

Printing is carried out as specified for the first page.

 Others

• MP Mode (SelecType setting) does not influence operation in Manual Feed
mode.

• If the paper source setting command and the Manual Feed command are issued
for the same page, the paper source setting is ignored.

<Recommended operation>

 Recommended operation to ensure that paper is fed from your desired paper

source:

1. Set only the required number of sheets in the desired paper source.

2. Remove all the sheets, if any, from the other paper sources or set the sources
unavailable.

3. Press the Start/Stop switch.

 Recommended operation when the printer is to be operated the same way as

the old model:

1. Set only one sheet of required paper in the desired paper source.

2. Remove all the sheets, if any, from the other paper sources or set the sources
unavailable.

3. Press the Start/Stop switch.

1.6 RAM Expansion

<EPL-5900>

When EPL-5900 runs out of memory, the Memory LED flashes or lights up.

NOTE: This indication corresponds to “Mem Overflow” or “Image Optimum”

or “Need Memory” or “Collate was disabled” displayed on the LCD of
an LCD-mounted model.

This problem may be solved by taking appropriate ones of the following measures:

 Reducing the resolution.

 Select “Halftone” when using Enhanced MicroGray.

 Reducing the receiving buffer size to “Minimum”.

 Use only one interface and set “Off” for other interfaces.

The only way to definitely avoid memory shortages is to install more memory.
(Commercially available (only for EPSON) SDRAM DIMMs for PCs: 90pins, 32-bit
without SPD)

<EPL-5900L>

If a problem with insufficient memory occurs in EPL-5900L, an underrun error is
displayed on the host computer's screen. In this case, it is necessary to install additional
memory.

Depending on use conditions, the recommended RAM capacity is as shown below.
However, there are some cases where an underrun error is displayed even when
memory has been expanded if an image of an extremely low compression ratio is
handled. In such cases, not only should the memory be expanded, but the resolution
should be reduced to 300 dpi, EnhancedMicroGray should not be used or other
appropriate changes made in the settings.

EPSON EPL-5900/EPL-5900L Revision B

1.10 Notes on Operation

1.10.1 Powering Off (EPL-5900)

EPL-5900 incorporates an internal non-volatile memory (EEPROM).
If the printer is powered off during the process of writing in non-volatile memory, the
writing operation to the non-volatile memory cannot be guaranteed. And therefore the
next time the printer is powered on or the “Reset All” is carried out, panel settings may
be initialized or a service call error may occur.
The non-volatile memory saves the function settings, and the following cases are those
in which the memory is rewritten, and therefore the printer should not be powered off:

 After the printer is powered on, until the Ready LED lights up.

 While the printer is printing.

(While the paper feed motor is operating.)

 While the Data LED is flashing or lit.

To stop the printer, either put it off line or carry out All Print Data Cancel.

1.10.2 Caution About Hot Parts (EPL-5900/EPL-5900L)

1.10.3 About the Moist Environment Mode Select Jumper
(EPL-5900L)

Jumper switch “JP9” on the controller board is a jumper for selecting the moist
environment mode.
This is a switch to be operated to lower the print density in a high humidity
environment. Ordinarily it should not be operated.
Use this switch only in cases where the above special environmental conditions exist.
When the environment of use returns to normal environmental conditions, it is
necessary to return it to the original setting immediately. The following jumper setting
1-2 is excluded from the print quality guarantee in the normal environment.

If the user environment is special and it is difficult to handle environmental conditions
by any other method, this setting can be set by a service technician. This jumper is not
disclosed to the public and is not accessible to users.

Setting:
1-2 Set if the printer is used in a high humidity environment.
2-3 Set when the printer is used in a normal humidity environment (factory

default setting).

2.2.2 Paper Feed Mechanism

2.2.2.1 Paper Tray

PAPER FEED OPERATION

When the paper feed solenoid (SL1) is turned ON, the driving power from the main motor
(M1) is transmitted to the paper feed roller via the paper feed clutch, and the paper feed
roller rotates.

At the same time, the push down cam rotates, and it lifts the tray. Paper on the tray is carried
into the printer by the paper feed roller.

Separation pad method is used in order to separate each sheet of paper and prevent feeding
the second sheet together.

Since there is no paper size sensor mechanism in the paper tray, the printer detects the
length of paper by the ON period of paper feed sensor (PS1), and judges the paper size.

So, when sheets of paper have the same length, the printer judges the sheets to have the
same size even if they are different in width.

PAPER EMPTY SENSOR

Paper empty sensor (PE1) is mounted on the upper part of the paper tray and it detects the
absence of paper in the paper tray.

When there is paper on the tray, the actuator is lifted and the sensor turns OFF.

When the tray is empty of paper, the actuator falls into the hole in the tray and the sensor
turns ON.

2.2.2.2 Lower Cassette Unit (Option for EPL-5900)

MECHANISM

Since the Lower Cassette Unit does not have drive motor, driving power in the Lower
Cassette Unit for feeding and carrying paper is transmitted from the printer (from M1) via
the connecting gear.

Paper feed method is the same as with the paper tray. However, paper separation method is
different; the separation pad method is used for the paper tray, while the separator claw is
used for the Lower Cassette Unit.

The separator claw method uses the paper separator claw installed at the paper cassette and
the elasticity of paper. Only one sheet of paper is fed by one paper feed operation.

The paper feed solenoid (SL21) is controlled from the printer side via the relay board
(PWB-A) of the Lower Cassette Unit.

PAPER EMPTY SENSOR

The paper empty sensor (PI2) is mounted on the relay board (PWB-A) of the Lower
Cassette Unit and it detects “paper empty” (absence of paper) in the paper feed cassette.

When there is paper on the tray, the actuator is lifted and the sensor turns OFF.

When the tray is empty of paper, the actuator falls into the hole in the paper lifting board
and the sensor turns ON.

CASSETTE TYPE SENSOR

The Lower Cassette Unit is equipped with the cassette type sensor switches (SW21) having
a sector-shaped lever.

When the cassette for a paper size is inserted, the switch presser on the right side of the
cassette pushes the lever according to the paper size and it turns the cassette type sensor
ON.

These triple switches enable the printer to distinguish the cassette types (paper sizes) by
ON/OFF combinations of the switches.

2.2.3 Charging Process

 Overview

Before laser exposure, static electricity is given to the OPC drum (Organic Photoconductor)
to charge it.

The surface of the OPC drum is charged by the rotating brush (charging brush) and pre­charging film.

Charging by the rotary brush (charging brush) and the pre-charging film rarely causes
ozone generation resulting from corona discharge. In addition, since charge is given directly
to the OPC drum, this charging method requires a low voltage and excels in homogeneity
and stability of the electric potential.

The pre-charging film performs preliminary charging before charging with the rotary brush
(charging brush) to enhance efficiency of charging.

The rotary brush (charging brush) is rotated by the driving force which is transmitted from
the main motor (M1) to the gear of the brush.

The electric potential on the surface of the OPC drum after charging is about -800V.

2.2.4 Exposure Process

The laser beam from the print head creates an electrostatic latent image on the OPC drum
surface.

The following control is performed in order to find the appropriate timing to print the
image.

SUB SCANNING DIRECTION (VERTICAL SCANNING DIRECTION)

When the printer receives the PRINT signal, the polygon motor (M3) and the main motor
(M1) operate, and paper feeding is started.

Upon passage of a specified period of time after the front end of the fed sheet turns the
paper feed sensor ON (TOD signal), the main control board sends the VIDEO signal to the
print head, and printing starts.

When moving on from the first line to the second line, the print starting position is shifted
down by delaying the VIDEO signal sending time

MAIN SCANNING DIRECTION (HORIZONTAL SCANNING DIRECTION)

The laser diode control board (PWB-D) is equipped with the SOS sensor to unify the timing
of the laser emission for every one line of main scanning.

2.2.6 Transfer Process

OVERVIEW

The image created on the OPC drum in the development process is transferred to the paper.

Transfer method is not the corona transfer but the roller transfer method by the transfer
roller.

By the roller transfer method, ozone generation resulting from corona discharge rarely
occurs, and the transferred image is little dislocated because the paper is always retained
between the drum and the transfer roller during printing.

A reversed bias is applied to the transfer roller during cleaning of the transfer roller prior to
printing.

The residual electric potential on the paper is removed by the discharge needle.

2.2.7 Fusing Process

Paper

OVERVIEW

In this process, the toner transferred to the paper in the transfer process is fused to the paper.

For fusing, this printer uses the heat roller fusing system. The sheet with toner on passes
between the heat roller, which is heated up by the heater lamp, and the back-up roller.
During this passage, heat and pressure are applied to permanently fuse the toner to the
paper.

FUSING TEMPERATURE CONTROL CIRCUIT

The thermistor (TH1) detects the surface temperature of the fusing heat roller and inputs the
analog voltage to IC1A-78. Based on the thermistor detected temperature, IC1A-55 outputs
the heater lamp ON/OFF signal. According to this signal, the heater lamp (H1) turns ON
(lights up) and OFF (goes out) to control the temperature of the fusing components.

If the heater lamp does not turn OFF even when the thermistor detects too high temperature
(when the surface temperature of the fusing heat roller exceeds 250

°

C), the output from IC-

79 changes from L to H and forcibly turns the heater lamp OFF.
