CUTTER SPECIFICATIONS
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 wear-
and-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.

1.3.3 Maintenance Errors
There are several consumable parts in the printer, and the printer employs
separate counters to keep track of each one. The “Maintenance Req. 0100”
message appears on the display to warn that the Waste Ink pads are about
99% full and need to be replaced soon.
The printer can continue to print even though the “Maintenance Req. 0100*
message appears instead of the “Ready” or “Printing” message. However,
when the waste ink counter determines the Waste Ink pads are 100% full, the
“Service Req 00000100” message appears and the printer can no longer print.
To clear the Maintenance error, perform the following.

1.5 Initialization
This section describes the initialization procedures for the EPSON Stylus Pro
9000. There are three ways to initialize the EPSON Stylus Pro 9000:
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
Clears the input data buffer
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
Control panel (operator) initialization:
When the Reset button is pressed or the printer receives an -INIT signal
(negative pulse) from the parallel interface, the printer:
Caps the printheads
Ejects the paper if a cut sheet is loaded
Clears the input data buffer
Clears the print buffer
Resets the default values
The default values are shown below.
Page Position: Current paper position as page-start position
Line feed: 1/6”
Right margin: 440th character
1.6 Interface selection
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.
Manual Selection:
Select the desired interface through the default setting mode, described
below under Maintenance Mode (Level 1).
Automatic Selection:
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.
Other things to keep in mind about interface selection:
The host checks whether the logic signal is low or high before requesting
data through the reverse channel.
If the parallel interface is not selected, it enters a BUSY state and the logic
signal is set low.
When the serial interface is not selected, the DTR (data terminal ready)
signal is set to MARK.
When the optional type-B interface is not selected, the off-line bit is set to
Main Status Register (MNSTS).
When the printer is initialized or returns to an idle state, the parallel
interface enters a ready condition, the serial DTR signal is set to low, and
the off-line bit of the Main Status Register (MNSTS) is reset.
The /INIT signal on the parallel interface is not active while that interface is
in Nibble or ECP Mode, or is not selected.

2.2 Description of Components
2.2.1 Carriage Mechanism
CR GUIDE RAIL
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.
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 thecarriage 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:
Carriage

Figure 2-5. Carriage Mechanism & CR Guide Rail
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.

EPSON Stylus Pro 9000 Revision B
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)
PG Gear
PG Cam
Printhead
Bearings
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:
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.
Subcarriage
(printhead slots)
Figure 2-6. Carriage Mechanism & CR Guide Rail (side view)
Be aware that the PG Cam and the PG Gear (hole) must
line up properlyfor 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.

Cutter solenoid
The solenoid is attached to the carriage on the opposite side of the home
position and it activates the cutter to cut roll paper. In order to cut roll paper
evenly, the following method is used:
1) The cutter cuts from the right of center (when facing the printout) to the
right edge.
2) The cutter cuts from several centimeters inside the left edge to the left
edge.
3) The cutter cuts the remaining uncut portion, in the center, from the left
side to the right.

2.2.2 Paper Feed Assembly
PF RAIL
The main paper feed components are the CR Guide Rail, the grid roller
assembly which is attached to the PF Rail, and the Secondary Roller Assembly
which attaches to the back of the CR Guide Rail and faces the grid roller
assembly. The grid roller assembly is made up of three equal lengths of rollers
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.

The Paper Release Lever is located on the right side of the printer, and this
sensor is attached at the bottom of the lever, inside the right-side frame.
This sensor’s signal goes “ON” when the lever is in the lock position,
meaning it is OK to print like a mad man.

2.2.3 Cleaning Mechanism
The cleaning mechanism for the SP 9000 is similar to the mechanism in the
Stylus Pro 5000. The main components are:
n Pump Assembly (Cleaner, Head)
n Pump Motor (stepping motor)
n Cap Assembly (B head/C head independent)
n Flushing Box R (receives ejected ink during flushing)
n Waste Ink pads
The cleaning mechanism components are installed above the subframe and
some are fixed on the main frame.
Additionally, the following unit is installed above the subframe.
n 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.
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.

SENSORS
The following sensors are located in the I/H compartment.
I/H Assembly sensor
This optical sensor detects the whether the door is open and the I/H
Assembly is in the install position or the door is closed and the I/H
Assembly is in the printposition.
When the I/H door is open, the signal = ON
When the I/H door is closed, the signal = OFF
Ink Cartridge sensor
This mechanical sensor (microswitch) is built in all six ink cartridge slots.
When the I/C is installed, switch = closed
When the I/C is not installed, switch = open
Ink Low sensor
This mechanical sensor (microswitch) is at the bottom of all six ink
cartridge slots and detects when ink is running out.
When the I/C is nearly empty, the switch = open
When the I/C is not low (normal), the switch = closed
Ink ID sensor
This optical sensor is located at the side of all six ink cartridge slots and
detects the which market the cartridge is for. Although not implemented
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.
Front
Cover
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.

2.3 Printer Mechanism Operation Outline
This section describes the various parts of the printer mechanism and how
those parts work.
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
voltagetothemotoraccordingly.
Print Control
The carriage speed during printing is described below.
Table 2-1. Carriage Speed
Print Mode Carriage Speed
720dpi & Normal M/W 200cps
4 Pass FOL printing 300cps
unidirectional 400cps
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
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
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.
Table 2-2. Platen Gap Settings
Platen Gap Setting Gap Distance
PG “Small” 1.3mm
PG “Medium” 2.2mm
PG “Large” 2.7mm
The actual platen gap position used during printing depends on the paper
thickness as well as the control panel Platen Gap setting.

PAPER FEED MECHANISM
Paper Suction
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.

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.

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.

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
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.
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 at4.2V. When the preset voltage level is detected, the Pin 8
sends a reset signal to reset the main logic circuits.
2.4.2 CR/PF Motor Driver Circuit
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.
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.

EPSON Stylus Pro 9000 Revision B
2.4.3 Head SLID 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.
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.
2.4.4 Pump Motor Driver Ci rcuit
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.

EPSON Stylus Pro 9000 Revision B
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.

Operating Principles Summary of Control Circuit Operations 54
Page 55
EPSON Stylus Pro 9000 Revision B
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.
o P_REAR Sensor
o P_FRONT Sensor
o P_EDGE Sensor
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.

3.2.1 Errors that require a service technician
This section describes the errors listed in Table 3-2 on page 58 in detail.
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
Waste Ink Pads (right, left)
F Box (right, left)
Pump Assembly
Cap Assembly
Cleaner, Head
SERVICE REQ. 00000100
Problem
The waste ink pads are completely full, causing a fatal error. The printer
stops printing.
Solution
See the solution for Maintenance Req. 0100.
SERVICE REQ. 00000101
Problem
A printer part has exceeded its useful life, and to prevent damage to other
parts as well as abnormal operations/printouts, an error occurs. This error
occurs when the CR Motor has reached 2.5 million passes, and this
indicates the Ink Tubes should be replaced due to excessive wear and
tear.
Solution
To make sure the Ink Tube is not worn out, verify no part of the tube shows
wear, is loose, or leaks ink anywhere, especially the tube area between the
printheads and the ink pipes.
SERVICE REQ. 00010000
Problem
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.
Check and adjust the PF Belt tension
Replace the PF motor
Replace the Main Board
SERVICE REQ. 00010001
Problem
PF motor out of step - the length of the PF motor internal encoder’s pulse is
too long or too short compared to the regular pulse.
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.

output (sensor signal) indicates that the PF motor’s current is irregular.
Solution
Replace the PF motor
Replace the Main Board
SERVICE REQ. 00010003
Problem
PF in-position time-out - The in-position time is the amount of time the
printer waits to make sure the carriage is not moving when the carriage
comes to a stop. The rotary encoder is activate for the predetermined “inposition time” and if the encoder sends a pulse, this means the carriage is
moving even though it is supposed to be at a full stop, this generates an
error.
Solution

3.2.2 General Errors
This section describes the errors that can be solved by the user.
CHECK
PO INT
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.
Solution
Replace the ink cartridge.
CHECK
PO INT
PAPER OUT
Problem
Paper is not loaded.
The rear edge of roll paper has been detected.
The print job using cut sheets is finished or the rear edge of cut-sheet
By using “Check: Test” function in the built-in selfdiagnostic mode, you can check control panel,
sensors, encorders function. Refer to Chapter-4
Adjustment for more details.
If for any reason you replace an ink cartridge before it
reaches the ink-low or ink-out state with a new ink
cartridge, you need to reset the ink counter using the
control panel and Maintenance Mode 2.
paper has been detected.
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.
CAUTION
Use a clean, dry cloth when cleaning sensors; never
use a wet cloth or soap.
LOAD XXX PAPER
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.
LOAD PAPER
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
to lock the paper in place.
If this error occurs even when the lever is down, in the Lock position,
there may be a problem with the Paper Release lever sensor. Check
the sensor operation, sensor connection, and board.

Page 64
EPSON Stylus Pro 9000 Revision B
PAPER JAM
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
and right cover-open sensors are correctly installed and are operating
properly.
PAPER NOT CUT
Problem
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

RELOAD PAPER
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
Properly reload paper. If the front edge of the paper is not straight and
clean, cut the paper.
4~5 above
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.
If the error recurs even after reloading the paper, make sure the paper-
end sensor on top of the carriage is installed correctly and working
properly.
PUSH LEVER DOWN
Problem
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.
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.

INK OUT
Problem
One or more ink cartridges have run out of ink, a near-end cartridge has
been reinstalled, or an unsupported ink cartridge has been installed.
Solution
Replace the empty ink cartridge.
CAUTION
When replacing an empty ink cartridge, always replace
it with a new ink cartridge; otherwise the printer
cannot determine how much ink remains.
Make sure the ink cartridge is the proper type of cartridge for the
printer and the proper color for that slot.
If the proper cartridge is installed and this error still occurs, check the
Ink-End sensor and the Ink ID sensor.
NO INK CARTRIDGE
Problem
An ink cartridge is not installed or is not installed properly.
Solution
Install the proper ink cartridge in the empty slot.
REMOVE PAPER
Problem
Printer cannot perform cleaning because of thick paper. (The printheads
are too far away from the Cap Assembly.) This error occurs under the
following conditions.
Thick paper is loaded when the periodic/timer cleaning operation is
supposed to begin.
The printer attempts to print on thick paper when the periodic/timer
cleaning operation is supposed to begin.
You turn on the printer and the thick paper is loaded.
You attempt to perform a manual cleaning operation when thick paper
is loaded.
Solution
Remove thick paper and push the Release lever down. (This causes the
cleaning to operation to start and “Wait” appears on the display.) After the
cleaning operation is finished, “Paper Out” appears. Load thick paper.
OPTION I/F ERROR
Problem
An unsupported Type-B interface card is installed.
Solution
Turn off the printer, remove the unsupported card, and install a supported
card.
CAUTION
When replacing an empty ink cartridge, always replace
it with a new ink cartridge; otherwise the printer
cannot determine how much ink remains.
If the proper cartridge is installed and this error still occurs, check the
Ink-Cartridge sensor.

3.3 Troubleshooting Based on Your Printout
This section describes the conceivable print quality problems that may occur
with this printer and the troubleshooting points for those errors.
Table 3-4. Print Quality Problems
Description Refer to
Dot missing page 67
Uneven printing/poor resolution page 68
Smudged or marred printout on front side page 68
Smudged or marred printout on reverseside page68
White/black banding page 68
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 There is no damage to or foreign materials in rubber of the Cap
Assembly
n The Cap Assembly valve is operating normally (if it is not, the Cap
Assembly will not properly absorb ink
n The Cap Assembly retention spring is working properly.
n The ink tubes and pipes between the ink cartridges and printheads are
properly connected and are not damaged (check the nuts for tightness,
the O-rings for warping, and the tubes/pipes for ink leakage)
4. If after following the above steps the printout still shows missing dots,
replace one of the parts listed below and check the print out.
n Main Board
n Printhead(s)
CAUTION
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
C head.
CAUTION
Do not charge ink too often as this operation
consumes a lot of ink. Each head consumes about
88.58ml per operation.
Troubleshooting Troubleshooting Based on Your Printout 67

EPSON Stylus Pro 9000 Revision B
UNEVEN PRINTING/POOR RESOLUTION
If printout quality suffers from unevenness, poor quality, or similar problems,
check the following.
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 orthick 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 abovesteps the printout quality has not improved,
verify the following.
n Head angle adjustment
n Head height adjustment
CHECK
PO INT
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.
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.)
SMUDGED OR MARRED PRINTOUT (REVERSE SIDE)
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.
n Sub-platen surface
n Grid roller surface
n Lower Paper Guide surface
If the problem is not caused by the above, most likely the paper jammed in the
printer or curled up after being ejected.
WHITE OR BLACK BANDING
If white or black banding (lines across the page) appear on your printout, try the
following.
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.
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.

4.1 Summary
This section describes the disassembly and assembly methods for the EPSON
Stylus Pro 9000. However, full assembly instructions are not given apart from
following the disassembly instructions in reverse order, and where special
instructions are necessary, check points are provided.
Where “Caution” and “Check Point” notes are given, be sure to confirm these
contents BEFORE starting the corresponding procedure. Where adjustment
procedures are necessary, “Adjustment Required” notes describe what you
need do to. These adjustment procedures are absolutely necessary and are
described in detail in Chapter 5, "Adjustment".
4.1.1 Warnings
Before proceeding with any disassembly or assembly work, make absolutely
sure of the following.
W ARNING
n The power switch is located at the top of the control panel,
and to prevent shock or damage to the printer, always
remove the power cable before disassembly or assembly
n 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.
n Because the Main Board pr ovides a Lithium battery for
memory backup purposes, you must keep the following in
mind when handling the Main Board.
- Be careful to avoid dama ging the Lithium electrodes due
to short circuits.
- When replacing the battery, make s ure the positive/
negative sides are installed correctly
- The battery can become very hot, so be careful when
touching it
n If ink gets on your hands, wash them thoroughly with soap
and water. If ink gets in your eyes, rinse them immediately
with water.
n 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 s uch as the carriage fan.
n Keep in mind that the steel carriage drive belt and cutter
blade can be dangerous.
Disassembly & Assembly Summary 70

EPSON Stylus Pro 9000 Revision B
CAUTIO N
n Before servicing or performing maintenance on the
printer, make sure you ha ve enough space. If you need to
move the printer, be sure the space is you move to is safe.
n Because the printer is much heavier than most printers
(about 96Kg for t he 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.
n 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.
n 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.
n 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.
n 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.
