CUTTER SPECIFICATIONS
Notes
Attributes:
Consumable item that is replaced by the user, and it
is made of very hard steel, so the blade can easily be
chipped.
Life:
Can cut well over 2,000 pages, but the actual wearand-tear depends on the type and thickness of the
paper used.
The cutter life can be determined by manually using
it to cut a piece of normal paper. If the cutter easily
cuts the paper, it is OK.
The cutter position is determined by the carriage
cover position; see “Carriage Cover Height
Adjustment” on page 139 and “Cutter Position
Adjustment” on page 140 for more information.
n Do not refill or reuse cartridges; they are consumable items.
n Do not use ink that beyond its expiration date. See above.
n To use ink that has been frozen [below 5 °F (-15 °C)], let it
thaw at least 3 hours at room temperature.

1.5 Initialization
1.6 Interface selection
This section describes the initialization procedures for the EPSON Stylus Pro
9000. There are three ways to initialize the EPSON Stylus Pro 9000:
The printer has three built-in interfaces: parallel, serial, and Type-B (an
optional interface requiring an interface card). These interfaces are selected
automatically or manually through the control panel.
Hardware initialization:
When the power is turned on or a cold-reset command is sent to the printer
(remote RS command), the printer does the following:
Initializes the printer mechanism
Manual Selection:
Select the desired interface through the default setting mode, described
below under Maintenance Mode (Level 1).
Automatic Selection:
Clears the input data buffer
Automatic interface selection is enabled by the default setting mode,
described below under Maintenance Mode (Level 1). When the automatic
selection is active, the printer passively scans all interfaces. The interface
that receives data first is selected as the active interface. When the host
stops sending data and the printer has been in a standby state for 10
seconds, the printer returns to an idle state. Otherwise, the interface
remains active.
Clears the print buffer
Restores the default values
Software initialization:
When the printer receives an ESC@ command, it does the following:
Clears the print buffer
Restores the default values
Other things to keep in mind about interface selection:
Control panel (operator) initialization:
When the Reset button is pressed or the printer receives an -INIT signal

2.2.1 Carriage Mechanism
HP Sensor
CR GUIDE RAIL
No HP signal
To print on paper as wide as B0 Wide, the printhead carriage must be more
stable and must travel further than the usual carriage. To make the printheads
more stable, EPSON added the CR Guide Rail to the SP 9000.
Linear
Encoder
Step Ruler
(plastic strip w/ shaded stripes)
Every EPSON ink jet printer until now has used a carriage guide shaft to
stabilize the carriage during printing and horizontal movement. SP 9000 does
away with the carriage guide shaft and relies on the printer frame for its
stability.
The CR motor uses a DC motor to move the carriage, and the Linear Encoder
determines the lateral position of the carriage by counting the shaded areas of
the plastic Step Ruler (timing fence). See Figure 2-5 below. The Linear
Encoder reads the shaded stripes to determine the position of the carriage as
well as the carriage speed, and this data is sent to the software servo. To allow
for the extra distance the carriage must travel during printing, the rubber timing
belt has been changed to a belt made from steel.
The following sensors are used in combination with the CR Guide Rail
components:
HP Sensor
This optical sensor activates when the CR Guide Rail flag (flag) enters the
space between the light emitter and the light receiver. The flag is located
just above the home position, and the HP sensor sends an “On” signal
when the carriage is in the home position.
Linear Encoder
This sensor is located on the back of the carriage, lower than the HP
sensor. For every shaded section the Linear Encoder passes over, the LE
sends a pulse to the CR motor as a PTS (Print Timing Signal). The shaded
sections have a distance equal to 180 dpi, and the software controls use
this spacing for reference purposes.

CARRIAGE
Unlike previous models, the SP 9000 uses a special system to ensure the
distance between the printhead nozzles and paper remains the same for all
supported paper types. The carriage (main) attaches to the CR Guide Rail
using bearings, and the carriage (main) contains the subcarriage. The
subcarriage holds the ink cavities, printheads, and so on.
Carriage
CR Guide Rail
(frame span)
The subcarriage can be moved using the PG Cam which is driven by the PG
Gears, causing the subcarriage and all its components to move slightly up or
down. The position depends on the thickness of the paper. The position
changes because the PG Cam is somewhat oval shaped and off-centered, so
one side pushes the subcarriage up further than the other side.
The printheads are the same type used in the EPSON Stylus Pro 5000, and
are installed in the same way. Therefore, when installing or replacing the
printheads, make sure neither head leans one way or the other, and make sure
the nozzles of both printheads are exactly lined up vertically. To adjust the
heads, separate adjust levers are provided.
Other sensors and components attached to or related to the carriage are:
PG Gear
P-EDGE sensor
This sensor measures the distance between the right and left edges of the
paper. The light emitted from the sensor is reflected back to the sensor
where paper exists. In this way the sensor determines where the paper’s
edge is and how wide the paper is.
PG origin sensor
This sensor detects when the subcarriage is in the thick paper position or
normal paper position. The PG Gear rotates with the PG Cam, and the PG
origin sensor uses a light-reflecting sensor to determine (according to the
hole in the PG Gear) the current subcarriage position, thick paper or
normal paper.

Bearings
Subcarriage

Figure 2-6. Carriage Mechanism & CR Guide Rail (side view)
Be aware that the PG Cam and the PG Gear (hole) must
line up properly for the platen gap adjustment operation
to work properly. The Can and Gear are lined up
properly if when the flattest side of the Cam faces the
Lower Paper Guide, the hole of the Gear faces the CR
steel directly above.

and their coupling.
The PF Motor uses a DC Motor and is controlled by the software servo system
which receives a pulse from the built-in optical rotary encoder. The PF Roller
torque is transferred through the PF Roller shaft edge (left frame), and turns
the PF motor pinion gear and timing belt.

SENSORS
The following sensors aid in the paper feeding process.
P-FRONT sensor
This sensor is attached to the back side of the Lower Paper Guide and is
an optical (photo-reflective) sensor. This sensor detects the front edge of
the paper after paper has been loaded but before it is set and ready to
print.
P-REAR sensor
This sensor is attached to the back side of the Upper Paper Guide and is
an optical (photo-reflective) sensor. This sensor detects the rear edge of
the paper as an end of page and detects the front edge when the paper is
first inserted in the paper path.
P-THICK sensor
This sensor physically gauges whether the paper in falls into the normal/
thin category or the thick category. The Secondary Roller unit closest to
the HP has a thin metal flag on top. When the Paper Release Lever is in
the Lock position and thin paper is loaded, this flag enters the space
between the sensor’s light emitter and receiver. However, when thick
paper is loaded the flag is forced forward out of the sensor area, signalling
that thick paper is loaded.

CR Lock Mechanism
The printer uses an electromagnetic solenoid to activate or release the
carriage lock. The carriage lock comes into effect when the carriage is
in the home position and the CR Motor is not running. When the
carriage lock does not receive any signal, the actuator rises into the
opening at the bottom of the subcarriage, restricting carriage
movement. To release the carriage for printing, the printer signals the
actuator which then moves down, releasing the carriage.

2.2.4 Ink Supply Mechanism
The two ink cartridge holders each hold three cartridges, K, C, and M on one
side and Lc, Lm, and Y on the other side. The design of the holders makes it
quite easy to install and replace ink cartridges from the front of the printer. The
I/H Lever opens and closes the I/H door, and at the same time it changes the
angle of the Ink Cartridge Holder Assembly as shown in Figure 2-12, "Ink
Supply Mechanism". To prevent users from accidently installing a color ink
cartridge in the wrong slot, the cartridges have slightly different designs.
I/H Lever
Another important feature of the ink cartridge holders is the ink valve, which is
located on the outer sides of the ink cartridge holders and shuts off the flow of
ink during printer transportation. The valve close under the following
conditions:
n
The user turns the valve to the “CLOSE” position to transport the
printer.
n
The I/H lever is lifted to the up/cartridge install position.
The ink flows out of the ink cartridges, through stainless steel pipes, through
ink tubes, and finally into the printheads.

currently, the sensor can also detect the type of ink (presently dye only)
and the type of special color (if new colors are introduced in the future).
The Ink ID sensor looks for the following marks on the ink cartridge.

Cover open sensor
To ensure proper paper feeding and to prevent paper jams, the front cover
must be closed during printing. There are two cover open sensors, one on
each side of the printer, that detect when the cover is open using an interlock
switch. When the cover is open, the relay that controls the current to the CR
motor and PF motor cuts off the flow of that current. The motors lose their
electromagnetized state when the current is cut off.
The sudden loss of current to the motors can cause problems and may even
damage the motors or the printhead. To prevent this, a discharge from the
capacitor connected to the current circuit is used to slow down the current
before it is totally cut off. This process ensures that printing stops when the
cover is open without causing any damage to printer parts.

travels. If the position of the carriage according to the Software Servo is
different from the position according to the encoder, a fatal error occurs
(Service Call 00010005).
PLATEN GAP MECHANISM
CARRIAGE MECHANISM
The carriage speed is determined by a software servo system. This software
servo is a closed-loop system where the CR motor (DC motor) must provide
constant torque or speed, so an encoder sensor is used to measure the output
and to provide feedback to the motor controller, which adjusts the current or
voltage to the motor accordingly.
To maintain a constant distance between the printhead nozzles and the paper,
the printer measures the thickness of the paper and adjusts the height of the
carriage accordingly. The printhead has three platen gap (height) settings, as
described in the table below.

The actual platen gap position used during printing depends on the paper
thickness as well as the control panel Platen Gap setting.
Table 2-3. Platen Gap Position & PG Settings
Due to the carriage’s quick acceleration process, even after the heads
reach and maintain normal speed, they are not stable enough to print for
the next 10mm.
Stop Control (stop position)
The encoder determines the carriage position by counting the stripes on
the Step Ruler. When the carriage reaches the predetermined position
(defined by the paper-size setting), the carriage stops. To make sure the
carriage has come to a complete stop, the printer checks the encoder for a
certain time (in-position time-out) to make sure no signal is generated
(indicating no carriage movement).
CR Motor Abnormality Detection
The software servo sends a series of pulses to the CR Motor to drive the
carriage a certain distance (depends on current operation, paper size, and
so on). At the same time the encoder measures the distance the carriage

PAPER FEED MECHANISM
The EPSON Stylus Pro 9000 feeds roll paper and cut-sheet paper using
friction-feed, and the sensor along the paper feed path provide all necessary
information for controlling the paper feed process.
Paper Suction Fan
The Paper Suction Fan is located behind the lower paper guide and sucks
air through the holes in the lower paper guide, pulling the paper flat/even
with the lower paper guide. This helps to keep the paper straight as it is fed
through the printer and prevents ink smears.

Next the carriage moves from the home position toward the opposite frame
and measures the distance from the home position to the opposite (right)
edge of the paper according to the brightness high and low levels. If the
paper edge has not been determined by a certain point (outside of the
printheads’ print range), the paper is loaded too far to the right and a
“Reload Paper” error occurs.
Once the opposite-side paper edge has been found, the carriage moves
from the opposite frame to the home position and measure the distance
from the opposite frame to the HP-side (left) edge of the paper.
Left-top

Paper size detection - right and left edges
Before printing the printer needs to determine the distance from the right
and left paper edges to the right frame and left frame (home position).
As shown in the following flowchart, the printer flushes the heads to make
sure no ink smears the paper as the printheads move across the paper.
Then the carriage moves to where paper should definitely be (if loaded
properly), near the vertical guide line. There the Paper Width sensor
determines the brightness level (high) of the light reflected off the paper. (If
no light is reflected, paper is not loaded or is not loaded properly and a
“Reload Paper” error occurs.) The carriage moves back toward the home
position, where paper definitely should not be if loaded properly, and
determines the brightness level (low) when light is not reflected off the
paper. This procedure is necessary to set the high/low levels when
adjusting for different media types, such as glossy or plain paper.

Paper condition detection
After paper is loaded in the printer, the printer performs the above left,
right, and leading edge detection operations to make sure the paper not
outside of the printable range of the printheads. If any of these edges is
outside of this area, a “Reload Paper” errors.
Basic loading procedure
Make sure the left edge (near the HP) is lined up with the vertical line
of holes in the Lower Paper Guide.
Normal loading area
Paper loaded within 10mm of the center of the vertical line of holes in
the Lower Paper Guide is considered in the printable zone; however,
paper loaded outside that 10mm zone causes an error.
Paper skew
In order to avoid printing on paper that is skewed or fed at a slant too far to
the right or left, the printer detects the right and left edges at the leading
edge of every page. If the printer determines that the paper is skewed 3mm
or more compared to the previous page, a “Paper Not Straight” error
occurs.
Basics
The right and left edge positions are checked at the top of every page.
Degree of skew
Any change in the edge position (from the originally detected position)
over 3mm causes an error.

2.4.1 Reset Circuit
2.4.2 CR/PF Motor Driver Circuit
The Reset-IC (IC7/BH6150F) used in the C277MAIN board has two built-in
reset circuits, each of which detects input voltage and power supply voltage
respectively as shown in the diagram on the right.
The EPSON Stylus Pro 9000 uses the DC servomotor to drive the CR and PF
motors. Therefore, the encoder is installed to detect the position, direction, and
speed of the carriage, and feedback from the encoder enables the software
servo control system to control the CR/PF motors.
Pin 2 detects the voltage level of the head driver, using the input terminal of the
input voltage detection circuit. The voltage level to be detected is preset at
1.25V. When the preset voltage level is detected, the Pin 2 sends a reset
signal to reset the mechanism control circuit.
Pin 8 detects the voltage level of the logic power supply, using the input
terminal of the power supply voltage detection circuit. The voltage level to be
detected is preset at 4.2V. When the preset voltage level is detected, the Pin 8
sends a reset signal to reset the main logic circuits.
The signal received from the Pin 60/61 in the IC32 enables the chopping
control system to control the output from the motor drive IC, and the output
from the Pin 10 in the motor drive IC (IC35/33) feeds back the output current
level to the IC32.
The Electro-magnetic Relay (LA1/LA2) is located on the power supply line for
the DC/PF motors, and it cuts off the power supply when the front cover is
open.

2.4.3 Head SLID Motor Driver Circuit
2.4.4 Pump Motor Driver Circuit
The Head SLID Motor vertically adjusts the position of the printhead on the
carriage according to the thickness of the media in the printer. The motor is
driven by the constant current bipolar drive system, and the current supply to
the motor is controlled by the PWM current control system. The 4-phase 48pole PM pulse motor is used for the drive motor, and it is driven by the W1-2
phase excitation.
The 4-phase 200-pole HB stepping motor is used to enable the ink system to
conduct ink absorption. The basic control method and the circuit configuration
are the same as those of the Head SLID Motor Driver Circuit.
Based on the preset data received from the IC20, the motor driver IC (IC31)
determines the current level to be output to the motor, and the motor is driven
by the drive phase switching signal which is input into the Pin 25/18.

2.4.5 Printhead Driver Circuit
The EPSON Stylus Pro 9000 uses the same printhead as that of the EPSON
Stylus Pro 5000 (both dark-color head and light-color head), and the basic
configuration of the driver control circuit is also the same.
Print data is rasterized on the memory (DRAM). Triggered by the LAT signal
(BHLAT, CHLAT), the IC13 reads the print data in the format and the order
according to the print mode, and transfers the data to the printhead (driver
circuit on the printhead) synchronizing with the clock signal (BHCLK, CHCLK).
The IC13 is equipped with the counter function, which keeps count of each
color’s data "1" being transferred to the printhead, and the accumulated count
is used to calculate the ink consumption.
The waveform signal is processed at the IC13. Triggered by the input of the
PTS signal from the CPU (IC8), the waveform signal is input into the DAC in
the IC37 as 10-bit data, synchronizing with the clock signal (20mHz). The DAC
then converts the head driver voltage waveform data to analog data, and
outputs it to the trapezoid waveform generation circuit (common driver).
The driver circuit on the printhead (nozzle selector) receives the serial data on
nozzle selection ("H" level = printing nozzle / "L" level = non-printing nozzle)
from the IC13. The circuit then latches the data to the data latch using the LAT
signal, and selects the printing nozzles and non-printing nozzles. Once the
nozzles are selected, the trapezoid waveform generation circuit (common
driver) generates the trapezoid waveform to fire ink. The NCHG signal
(BHNCHG, CHNCHG), which is input into the printhead from the IC13,
prepares all the nozzles for the next firing by applying slight vibrations during
the non-printing phase.

2.4.6 Sensors
The output signal sent from each sensor of the EPSON Stylus Pro 9000 is
connected to each IC on the control circuit as shown in the diagram on the
right.
In order to process the detected results as analog signal, the following sensors
input the results into the analog port in the CPU (IC8) via comparator. The
analog signal is then converted to the digital signal by the CPU built-in ADC
(10-bit) and is compared with the standard value for state analysis.

Thermister is attached to the printhead to monitor the temperature around the
printhead, and it feeds back the detected temperature to the CPU, which in turn
conducts the driver voltage adjustment according to the temperature detected.

Problem
MAINTENANCE REQ. 0100
Problem
The waste ink pads have absorbed 99% of their potential. The printer can
continue printing, but the “Maintenance Req. 0100” message appears
instead of the “Ready” or “Printing” messages.
Solution
Replace the following parts and reset the ink counter
PF motor encoder check error
The PF motor makes small revolutions clockwise and counter-clockwise.
When it turns, the printer checks the rotary encoder output signals to make
sure the motor is turning at the correct speed/distance. If there the encoder
doesn’t send the correct signal or output data, an error occurs.
Solution
Make sure there is nothing blocking the grid rollers. If that does not solve
the problem, check the PF motor encoder connection. If there still is a
problem, try the following.

Solution
If paper has run out, remove the printer paper and load new paper. If
print data remains in the printer, the data will be printed.
If this error occurs even though paper is properly loaded, there may be
something on the P-Rear sensor’s surface. Clean the sensor’s surface
(hole in the Paper Guide, Upper) with a clean, dry cloth.
C A U T IO N
Use a clean, dry cloth when cleaning sensors; never
use a wet cloth or soap.
INK LOW
Problem
An ink end sensor has detected that the corresponding ink cartridge is
almost empty (ever ink cartridge has an ink level gauge). It is possible to
print about 100% duty on B1 size paper with the remaining ink, but the
cartridge should be replaced as soon as possible.
If you re-install an ink cartridge that was detected as being in a “Near End”
state, the status will immediately go to “Ink Out”. Only install new
cartridges.
Problem
The selected paper source (according to the remote PP command) and the
paper type selected on the control panel do not match.
Solution
Load the correct paper or change the panel setting to match the type of
paper loaded in the printer.
Solution
Replace the ink cartridge.

Problem
While paper is loaded, the Paper Release lever was pushed up to the
Release position.
Solution
Make sure paper is loaded properly and push down the Release lever

PAPER JAM
PAPER NOT CUT
Problem
Problem
A paper jam occurs when during printing, paper feeding, or paper cutting
the carriage is not able to move properly (due to paper catching on some
part). The printer determines a paper jam has occurred if the P-Front
sensor and P-Rear sensors are in the “on” state but the CR motor is out of
step or has overcurrent.
Solution
After removing the paper stuck in the printer, the “TURN OFF AND
ON” message appears on the display. The printer is ready after you
turn the printer off and back on again.
If a paper jams occurs again after removing the original paper jam,
check to make sure nothing is blocking the feed path or blocking the
carriage.
COVER OPEN
Problem
The front cover is open.
This error occurs when the cover is opened during carriage operation or a
cleaning operation, causing the CR/PF operation and ink sequences to
stop. If the cover is left open too long, the printheads may be damaged. (To
avoid this problem, press the Pause button before opening the cover. But
be aware that a stripe may appear on the printout indicating the different
drying times.)
Solution
Close the cover as soon as possible.
If the cover is fully closed when this error occurs, make sure the left
The paper that was supposed to be cut was not cut completely, or the
paper was cut but is still in front of the P-Front sensor.
Solution
Remove the cut paper if it is on or near the Front Cover and Lower
Paper Guide.
Replace the cutter if it is worn out.
If the paper was cut, but not cut straight across, you need to adjust the
cutter position. See “Cutter Position Adjustment” on page 140 for
details.
PAPER NOT STRAIGHT
Problem
This error occurs when the printer detects the front and rear edges to be
skewed (the paper is loaded at an angle/slant) by more than 3mm. If the
printer prints on paper that is loaded at a slant, the printer may print outside
of the printable area and may fire ink onto the platen. If this happens, the
next sheets loaded in the printer may have marred reverse sides.
Solution
Remove the paper loaded in the printer and properly reload it
according to the instructions in the user’s guide.
For roll paper, the edges of the paper may not be lined up; (remove the
paper) and carefully squeeze the sides of the roll to make sure the
edges are lined up and flat.

RELOAD PAPER
PUSH LEVER DOWN
Problem
Problem
This error occurs when,
1) The front edge is loaded too far and the paper is not in the loading
position after it is reverse fed.
2) The paper was loaded in such a way that the left and/or right edge is
out of the printable area (due to mis-loading or because the paper is too
wide).
3) After printing has finished, the right or left edge is out of the area where
the cutter can cut the paper.
4) The loaded paper was longer than the selected paper, and the paper
was not fully ejected. (For example, roll paper is loaded in the printer but
cut sheet is selected on the control panel.)
5) A cutter error occurred after the paper was ejected.
Solution
1~3 above
The printer is not able to continue paper feeding/initializing, printing, or ink
sequencing because the Release lever was moved to the Release
position. Or, the printer cannot begin printing because the lever is in the
release position.
Solution
Push down the lever. However, if printing was interrupted because the
lever was pushed to the release position and the paper shifted, the
print job may be marred.
If the lever is down and this error still occurs, check the Release-Lever
position sensor.
COMPARTMENT OPEN
Problem
An Ink Holder (I/H) compartment door is open.
Properly reload paper. If the front edge of the paper is not straight and
clean, cut the paper.

Cut of the section of the paper that has ejected/protruded and reload
the rest of the paper. For paper that is automatically cut, lift up the
Release Lever (the “Load Paper” message appears), fix the position of
the paper, and lower the Release Lever. If you select you “Roll Paper/
Auto Cut” setting, you can cut off the protruding part of the paper using
the Cut button.
Solution
Push the I/H lever down to the lock position.
If the lever is down and this error still occurs, check the lever position
sensor.
If the error recurs even after reloading the paper, make sure the paperend sensor on top of the carriage is installed correctly and working
properly.

DOT MISSING
When the printer is not used for a long period of time, the ink in the nozzles can
dry up and clog the nozzles. Clogged nozzles cannot fire ink and cause the
dot-missing problem in printed documents. If the printhead nozzles do not clear
after attempting multiple cleaning operations, check the following points.
1. If there is no output at all or only some the colors print, check the ink valves
on either side of the printer I/H Assemblies to make sure the knobs are set
to “Open”. (Also, see the user’s guide or printer software.)
2. Perform ink charging again
Select the “Cleaning” function on the control panel’s Self-Diagnostic menu.
This sends a lot of ink into the heads and forces out the old ink that is
clogging the nozzles.

3. If the extra ink charge does not clear the clogged nozzles, confirm the
following.

n Before you uninstall the Main Board or a printhead,
make sure all cables are disconnected. After
installing the new board or head, make sure all
cables are properly connected; if cable connectors
not completely inserted, they can damage circuits
or the heads when current is turned on.
n Make sure you replace the correct head, B head or

UNEVEN PRINTING/POOR RESOLUTION
SMUDGED OR MARRED PRINTOUT (REVERSE SIDE)
If printout quality suffers from unevenness, poor quality, or similar problems,
check the following.
The reverse side of the paper can become smudged or marred if there is ink on
the printer parts. Make sure there is no ink on the following parts, and if there is
ink, wipe off the affected parts.
1. Perform platen gap adjustment
Using the control-panel setting or the diagnostic-program function, check
the platen gap (bi-directional printing position as well as PG adjustment).
2. If this error occurs only when the user prints on custom or thick paper, (Use
the control panel paper thickness setting to correct the paper size and the
print position (depending on the paper-thickness setting, the location
where the ink strikes the paper may change))
3. If after following the above steps the printout quality has not improved,
verify the following.

n Sub-platen surface
n Grid roller surface

WHITE OR BLACK BANDING
If white or black banding (lines across the page) appear on your printout, try the
following.
When using the “Adj.B (or C) Head Skew” as well as
the “Adj:PG Check Height” functions, always perform
the Gap Adjustment or Bi-directional Position
Adjustment operation.
1. Cleaning
2. If multiple cleaning cycles don’t clear the banding problem, try adjusting the
heads as described below.
n Head slant adjustment (B head/C head)
If all the nozzles in the B head and C head are not perfectly lined up,
the raster lines will overlap. The unprinted area between one line and
the next line (where a nozzle was supposed to fire but missed) is
banding.
SMUDGED OR MARRED PRINTOUT (FRONT)
The front, or top, side of the paper can become smudged or marred if it rubs
against the printhead surface. If this happens, verify the following.
1. If the smudged area is just around the front or rear edge of roll paper, make
sure the margins (top and bottom) are set to 15mm on the control panel.
(When printing high-duty print jobs with the top and bottom margins set to
3mm, the high volume of ink can cause the paper to warp and rub against
the printhead surface.)
n Head height adjustment (B head/C head)
n Bi-directional print position adjustment
n Gap adjustment opening
2. If this problem recurs, check the Cap Assembly retention spring. If this
spring is broken or comes off its hook, the Cap Assembly cannot wipe ink
off the printhead surface, and that ink will smudge the printout. Fix or
replace this spring.

Summary
and to prevent shock or damage to the printer, always
remove the power cable before disassembly or assembly
For safety reasons, the front cover position, up or down, is
automatically detected by the cover-open sensors which
are interlock switches. Do not block or modify these
sensors.
Because the Main Board provides a Lithium battery for
memory backup purposes, you must keep the following in
mind when handling the Main Board.
- Be careful to avoid damaging the Lithium electrodes due
to short circuits.
- When replacing the battery, make sure the positive/
negative sides are installed correctly
- The battery can become very hot, so be careful when
touching it
If ink gets on your hands, wash them thoroughly with soap
and water. If ink gets in your eyes, rinse them immediately
with water.
If it is necessary to remove external printer parts while the
printer is on to view the internal operations, be very
careful around high speed parts such as the carriage fan.
Keep in mind that the steel carriage drive belt and cutter
blade can be dangerous.

printer, make sure you have enough space. If you need to
move the printer, be sure the space is you move to is safe.
Because the printer is much heavier than most printers
(about 96Kg for the printer and options), you need to take
extra care. If you need to take apart the printer and stand
or lift the printer, four people are necessary.
Ink may leak onto other printer parts or the printer basket
when removing printer parts, so it is recommended to put
a sheet or cloth under the printer, especially when
working on or near ink-related parts.
When working on the electrical circuit board, be careful
concerning static electricity, which can cause damage to
the board. If necessary, use an anti-static wrist band or
similar grounding device to prevent static electricity
buildup.
When removing/re-inserting the flat-cable (FFC) from/to a
connector, make sure to pull/insert the cable straight.
Otherwise, internal contact of the connector may be
damaged and this causes a short-circuit to destroy the
electrical circuitries.
The cutter blade is very hard and can damage or scratch
printer parts, and it can also be chipped or damaged. Be
careful when handling or replacing the cutter.

1. Remove the access cover the top of the Upper Paper Guide, if necessary.
Also, make sure the Control Panel unit is attached.
5.2.1 Parameter Backup
The Main Board contains Flash ROM memory which is used to store the
parameter information and firmware commands that control the printer. For all
corresponding printer parts, the individual and unique adjustment information
and part codes are stored here, which allows the Main Board and Printer
Mechanism to work together smoothly. This information must be kept up to
date for the printer to work properly.
Therefore, before performing service that requires the removal of the Main
Board, you need to back up all of the parameters in case you have to update a
new Main Board which must work with the Printer Mechanism exactly the same
way the old one did. Backing up the parameters also helps minimize the
amount of and number of adjustments you may need to perform.
REQUIREMENTS FOR BACKUP
#F727 Flash Memory Card (1050073))
(Conforms to PCMCIA Rel 2.1/JEIDA Ver 4.2 (Type II) / 5V Read/Write
operation)
IPL data
Before backing up the parameters to the PC card, the following file must be
copied to the Flash Memory Card:
2. Insert the PC card into the PC card slot connector on the Main Board, and
then turn on the printer.
3. Make sure the following message appears on the LCD, and wait for the
procedure to begin.
Wait:F->M Push:M->F
4. The backup procedure starts about 15 seconds after the message
appears.
Flash -> Mcard
C A U T IO N
Do not touch the Control Panel buttons during this
procedure. Doing so causes the PC card to download
its data to the Main Board’s Flash memory instead of
backing up the data in Flash memory. This overwrites
the Flash memory so be careful.
5. When the backup procedure is finished, the following message appears.
Backup.exe (distributed on manual/STK CD-ROM)
End [Success]
C A U T IO N
Adjustment
BACKUP.EXE is a self-extraction file and you have to
copy extracted data to the PC Card.
You cannot back up the firmware that is stored on
the firmware backup PC card. Attempting to back up
the card will result in the loss of firmware data.
6. After making sure the printer is finished, turn off the printer and remove the
PC card.

message appears on the LCD.
2. Insert the PC card containing the backup data into the PC card slot
connector on the Main Board, and turn on the printer.
End [Error]
3. Make sure the following message appears on the LCD.
If you see the message above, one of the following errors has occurred. Using
a different PC card, try the operation again.
Wait:F->M Push:M->F
4. Press any button on the Control Panel to start the download procedure.

C A U T IO N
If you wait 15 seconds before you press one of the
Control Panel buttons, the printer will start the backup
procedure instead of the download procedure. This
overwrites data stored in the PC card with data stored

If using a different PC card does not solve the problem, there is a problem with
the flash memory on the Main Board and a backup is not possible.
5. When the download procedure is finished, the following message appears.

ADJ CAP POSITION
ADJ CHECK SKEW
Use this function to check the actual capping position and correct the capping
position parameter in the firmware if necessary.
When the band turns a predetermined amount (during printing), the printer
detects the paper edge using the P EDGE sensor. This value is compared to
the originally detected value for the paper-edge position to determine if the
paper is feeding at a slant. This adjustment is for service printouts and does not
affect user printouts.
There may be very small differences between printers. Although the difference
may only be a few pulses closer or further the linear encoder,This is necessary
to correct for any differences between one mechanism and another.
1. Make sure "Adj Cap Position" appears on the LCD and press the Enter
button.
2. The printer begins the HP detection sequence and automatically detects
the capping position.
3. After the adjustment process is finished, the detected distance between
the HP and the capping position is displayed.

ADJ REAR SENSOR POSITION
Measure this value
and enter it.
This function makes sure the P REAR sensor correctly detects the rear edge of
cut-sheet paper to allow the user to print with the largest possible printable
area but without printing off the edge of the paper and marring future printouts.
The printer prints an A3-size test pattern. Using a ruler, measure the distance
from the rear edge of the pattern to the rear edge of the paper, and then enter
this measurement when prompted. This value is stored in the printer’s firmware
to be referenced against the printhead nozzle position.
1. Make sure "Adj Rear Sensor Pos." appears, and press the Enter button.
2. Load A3-size paper in portrait (short edge first) orientation when you see
the "Please Set CutSheet" message. After the paper initializes, press the
Enter button to print the check pattern.

CARRIAGE COVER HEIGHT ADJUSTMENT
3. While holding the cutter in position with the tool, push the carriage cover
down to fix the cutter in place.
This adjustment is necessary for service operations that require you to remove
the carriage cover. The carriage cover limits the operation of the cuttersolenoid actuator, and it acts in a way to fix the stroke or movement of the
cutter during paper-cutting operations.
4. Replace the two carriage cover screws, move the carriage, and remove the
tool.
The standard height from the cutter’s bottom surface to
the subplaten’s upper surface is 9.75 ± 0.25mm.
1. Set the "CR Cover Position Adjustment Tool #F724" at the specified
position on the surface of the Lower Paper Guide so that it lines up with the
subplaten as shown below.
2. While lining up the indented gutter of the tool with the cutter blade, move
the carriage over the tool. Make sure the tool fits tightly against the
subplaten and Lower Paper Guide while securing the cutter blade in the
gutter.

CUTTER POSITION ADJUSTMENT
This adjustment is necessary for service operations that require you to remove
the Lower Paper Guide. The subplaten, which lies on top of the Lower Paper
Guide, guides paper as it is fed and provides support as the cutter performs the
cutting operation. The subplaten and cutter must be aligned properly for the
cutting operation to work.
Carriage
Paper
1. Load a suitable piece of paper in the feed path so that it protrudes over the
subplaten and lock the release lever.
2. Move the carriage over the paper by hand.
3. Push the cutter down by hand and move the carriage and cut off the paper.
4. Compare the position of the cut line on the paper to the edge of the upper
surface of the subplaten, as shown in Figure 5-14.
The blade should be below the edge, but close to the
edge. The standard distance (lateral) from the blade to
the subplaten’s upper surface is 0.5 (0.2~0.7mm).
If the cut line is above the edge or too far below the edge, reposition the
Lower Paper Guide and repeat the above steps.
5. Perform the above steps at the right side, left side, and center of the Lower
Paper Guide to make sure the guide is even.
C H E C K

the AC plug socket in order to prevent electric shock
during service operations.
n The cover open sensor for detecting the open/close
condition of the front cover has an interlock switch
that functions as a safety device. Therefore, it is
prohibited to turn off this switch.
n A lithium battery is used to back up memory and is
mounted on the control circuit board. To prevent
accidents, follow the precautions below when
handling the board.
*Do not short the battery.
*Do not set the battery on the wrong poles, double
check the plus and minus sides when installing the
battery.
*Do not heat up or place the battery neat a heat
source.
n Be careful not to let ink get into your eyes or your
skin. If ink gets in your eye, flush the eye with water,
and see a doctor if you feel discomfort in your eye.
Maintenance & Setup
n Due to the printer’s size, when performing any
service or maintenance operations, confirm there is
plenty of space for the operation.
n Due to the printer’s size and weight, make sure the
area you move and place the printer is stable.
n Since the EPSON Stylus Pro 9000 is very heavy
(approximately 96 Kg for the printer body + stand),
be careful when handling it. When separating or
assembling the printer body and legs, it is
recommended to do so with at least 4 people.
n When removing parts, ink may drip on the floor or
lower sections of the printer. Therefore, spread a
sheet or similar object when removing ink-related
parts.
n When handling the electric circuit boards, do not
touch the elements on the board by the bare hands in
order to prevent the elements from getting damage
by static electricity. If necessary, wear the earth
band.
n If it is necessary to power on the printer after
removing various covers by necessity, be careful not
to get injured from the carriage or fan.
n Since the steel belt for driving the carriage and cutter
blade are very sharp, be careful not to cut yourself.
n Since the cutter blade is made of very hard material
but weak against shocks, do not let it collide with the
printer’s metal parts.
n If the installed printer needs to be packed and
transported for any reasons, use the all the exclusive
packing materials and protection materials written
on the “Start-Up Guide” and “Assembly and Setup
Guide”.

6.1.1 Periodic Maintenance Items
6.1.2 Product Life Information
The printer uses sensors and counters to determine when consumable items
need to be replaced. When a consumable part has reached its predetermined
end-of-life according to the corresponding counter, a message appears. See
the table below for parts which require periodic replacement.
The table below shows the product life about the printer body, each
mechanism and various parts. Information regarding to the product life can be
checked by the following way.

Description
Solution
Replace the following parts;
Waste Ink Pads (R/L)
Pump Assembly
Cap Assembly
F Box (R/L)
Cleaner, Head
*Required Adjustments
Waste Ink Counter Clear
(See “Counter Clear” on
page 130.)
Cleaner Counter (See
“Counter Clear” on
page 130.)
Cutter Position Adjustment
(See “Cutter Position
Adjustment” on page 140.)
Solution
Check the ink tube
(The printer indicates this
error when the useful-life
ends for the specified part.)
When replacing the waste ink pads, replace the pads
in the waste ink tank and not the whole tank. Put the
old pads in a plastic bag and throw away the used ink
pads correctly, according to the laws and rules in your
area.
Maintenance & Setup
Panel Setting: “Printer Status Menu”
The amount of ink remaining is indicated on the LCD. (“F*****E” - F = full, E
= empty, and each asterisk * represents a percentage of the total ink.)
Also, the counters which record these values can be initialized by
“Maintenance Mode 2”.
C A U T IO N
Do not perform the counter initialization without
replacing the corresponding parts and checking their
operation. Since the counters for “Waste Ink Life” and
“Ink Remaining Quantity” influence printer operations,
do not clear them unnecessarily.
Self-Diagnostic Function: “Check: Maintenance” under “Test” menu
