1.4.10 Default Setup Values

1.4.10.2 Ink Type Setting

1.4.10.1 Initial Setting for Operation

In ink type setting during initial operation, dye ink will not be recognized if the switch
No. 6 of the DIP Switches (SWD600) on the Main Board of the printer.

Default setup values are as follows. The parameters for items that may be saved for
panel setup, default setup, and remote commands are used as default values.

Page position: Current paper position as page start position
Line feed: 1/6 inch
Left margin
: Stylus Pro 7600 237th character
: Stylus Pro 9600 437th character
Right margin: 1st character
Character pitch: 10 cpi
Print mode: Text mode
(non-raster graphics mode)

There may be a case where "Ink Type" is not set (NPD=0) by ink detection at power on
(with the cartridges installed and without any other error). In such a case, check the
position of the switch No. 6 of the DIP Switches.
NOTE: When the power is turned off without the cartridges installed, NPD=0
will be maintained.

When switch No. 6 is OFF (dye prohibited)
When pigment has been installed
• Sets "Ink Type" for the printer to "Pigment".
• Initial charge is started if the initial charge flag has been set.
• Every time the power is turned on after that, the printer will start as the

•

•
•

Pigment machine.
When dye has been installed
Displays "INVALID CARTRIDGE".
(The LEDs for all colors flash even when dye for only one color has been
installed.)
Does not set "Ink Type" for the printer. (NPD=0 is maintained)
NPD=0 even at the next start of the printer.

When switch No. 6 is ON
• Determines the ink type from the ink set that has been installed properly.
• If the printer is currently used as the dye machine (NPD=2), the printer does

not make judgment at power on. Therefore, the printer can be used as the dye
machine the same way as before.
• Even when "Ink Type" is changed to "Dye" directly in NPD mode, the printer
can be used as the dye machine.

PREVENTION HOSTS FROM DATA TRANSFER TIME-OUT
When data is received from the parallel interface or the type B interface while no error
has occurred (including the pause condition), the printer receives data a rate of 2 byte/
second while buffer free space is less than 16 kbytes in order to prevent host timeout.
When buffer free space is more than 32kbytes, the 2 byte/second receive rate is cleared,
and receive is halted when free space reaches 16 bytes, and returns to the 2 byte/second
rate when free space reaches 512 kbyte or more.

CARRIAGE MOVING UNIT
In place of the carriage holding system in which 2 CR guide shafts extending in the
column direction were used, as in the conventional models, a structure with the
carriage mounted via multiple rollers (bearings) on a CR guide rail made of a square
extruded aluminum pipe is used. Steel rails are incorporated in the roller contact and
running surface, and the result is a reduction in friction in the direction of movement,
reduced vibration and improved durability.

The screws used to fasten the CR guide rail should not be taken out
and the carriage should not be removed. These are adjusted and
assembled to the nearest 1/100 mm at the factory.

Step Ruler (Slit Plate)

CR motor
A DC motor is used for the CR motor and the slit in the timing fence affixed on the
bottom of and parallel with the CR guide rail is read by the encoder sensor
mounted on the carriage (linear encoder system), and this signal is compared to
logical control values in the control circuit on the MAIN board, which carries out
feedback speed control. Through this control, high print precision is maintained.

CR_HP Sensor (Carriage Home Position)
This is a transmissive photosensor which is mounted on the right end of the printer
mechanism and detects the entry position of the flag (projection) provided on the
carriage as the carriage moving home position. Outputs from this sensor are
“OFF” in the HP range and “ON” outside the HP range.

CR encoder sensor (Linear Encoder)
This encoder is mounted on the back of the carriage and outputs pulses (2
channels) corresponding to the position of the slit on the timing fence that is
incorporated into the CR guide rail which are used for CR motor servo control and
PTS (Print Timing Signal) generation. The resolution is 1/180 inch.

PLATEN GAP ADJUSTMENT UNIT
In order to maintain the print precision, it is necessary to maintain the carriage (= head)
mounting position so that it is always a constant distance from the surface of the paper.
In this printer, the print head nozzle surfaces and platen surface are variable
mechanisms so that the gap between the paper printing surface and the head nozzle
surface can be kept constant.
The carriage has a 2-body construction with a sub-carriage on which the print heads are
mounted attached to the carriage which forms the base. The sub-carriage moves in the
vertical direction with respect to the paper surface. This movable system uses a cam.
The sub-carriage to paper surface distance changes linearly from the cam (= PG) home
position. When the carriage is in the HP position (= right end), the pump motor and the
gear mounted on the cam shaft engage, the motor's rotation (reverse) drives the cam
and the sub-carriage is positioned at the proper gap position.
In order to maintain the distance between the print head nozzle surface and the paper
properly, the thicknesses of the paper used are classified into 3 levels for PG setting,
namely, PG small (1.3 mm), PG medium (2.2 mm) and PG large (2.7 mm).

HD_SLID (Head Gap Home Position Detection) Sensor
This sensor detects the mechanical home position when the position of the subcarriage (head height from the paper surface) on the carriage undergoes change. A
reflective type photosensor is used and the position of the flag on the gear mounted
on the camshaft is detected.
The cam is so shaped as to realize the four head positions relative to the
mechanical home position.

P_EDGE (Paper Width Detection) Sensor
This sensor, mounted at the left side of the cutter unit of the carriage, detects paper
edges by moving the carriage.
It detects four points of paper edges, namely, left and right points on the front edge
and a front point on the left and right edges of the paper. Each position is
calculated from the difference in reflection value between the platen and the paper.
A reflective type photosensor is used. Each paper edge position (presence or
absence of paper) is determined by an A/D converted value of the output from the
photosensor.
During printing, the sensor monitors the left and right edges of the paper to detect
a skew.

It must be ensured that the reflection value of the least
reflective paper is greater than the reflection value of the
platen.
The paper must be free from floating at the detection point.
If external light, such as sunlight, can enter the sensor due to
the construction, mis-detection must be prevented by LED ON/
OFF control.
(Same as with Stylus Pro 7000)
In Stylus Pro 7600/9600, the P_EDGE Sensor works also to
detect the paper front edge. (Stylus Pro 7600/9600 does not
have the P_FRONT Sensor for exclusive use to detect the paper
front edge which is incorporated in the conventional printer
models.)

2.2.2 Paper Feed Assembly
This printer uses friction feed to carry out highly precise feeding of roll paper and cut
sheets, and comprises a unique paper feed mechanism.
The paper feed mechanism unit is configured from a grid roller (one piece
construction), and pressurizing and follower roller assemblies mounted on the back of
the CR guide rail opposite the front surface.

The PF motor is a DC motor. The grid of the loop scale mounted on the Grid
Roller is read by the PF_ENC sensor and the output pulse is fed back to control the
motor. This feedback control ensures high printing accuracy.
Driving of the grid roller is accomplished by the PF motor via the PF timing belt
which attaches to a reduction pulley that is connected to the grid roller.

Paper Suction Fans
The printer is equipped with suction fans in the lower space in the rear. The space
in the column direction behind Paper Guide L2 is divided into 2 compartments
(Stylus Pro 7600) or 3 compartments (Stylus Pro 9600), and one fan is mounted in
each compartment. By drawing air through multiple holes punched in Paper Guide
L2 in the back surface of the paper path and blowing it out through the rear of the
printer housing, suction is applied to the surfaces of Paper Guides L1 and L2 and
the paper is stabilized (prevented from flying up) as it passes through the printer.
The suction fans undergo air flow control (fan rotation duty control), which is
carried out by firmware control based on the printer's operating state (when paper
is set and during printing, etc.) and the type of paper used.

P-Rear sensor

The following sensors aid in the paper feeding process.

P_REAR sensor
This sensor is attached to the Upper Paper Guide and is an optical (photoreflective) sensor. This sensor detects the rear edge of the paper and detects the
front edge when the paper is first loaded in the paper path. The position of this
sensor is stored in EEPROM.

P_THICK_0.3 Sensor:
Transmission type photosensor, left side.
P_THICK Sensor:

The mechanism is so designed that the threshold values for paper thickness are 0.3 ~
0.4 mm (P_THICK_0.3 sensor) and 0.8 ~ 0.9 mm (P_THICK sensor). The sensors
operate just when the pressure lever is brought down.
The designed detection values of the sensors for the UP and DOWN positions of the
pressure lever are 0.3 mm and 0.8 mm. The pressure lever in the UP position is
detected by a combination of both sensors.
“Thick paper state” occurs when the connections are open.
There is no error processing since this mechanism can not determine whether it has
broke down or not.
Since the mechanism is always in recognition of thick paper, printing on thin paper is
carry out with the platen gap kept large.

2.2.3 Cleaning Mechanism

Cleaning Mechanism
(Maintenance ASSY)

The cleaning mechanism in this printer is compatible with the cleaning mechanism in
the Stylus Pro 5000/9000. The cleaning mechanism is located on the right side of the
printer. The waste ink from the cleaning mechanism is channeled to the waste ink pad
(Maintenance Tank) in the lower right side through the tube.
The cleaning mechanism components are installed above the sub-frame and some are
fixed on the main frame as shown below.

Pump assembly (head cleaner)
When the head is in the capped position (valve closed), the pump motor creates a
vacuum that sucks ink from the nozzles. This is used for removing ink from the
nozzles and nozzle plate, initial ink charge, as well as cleaning. The waste ink
flows through one small tube to the waste ink pads.

Head cleaner
The head cleaner has felt on one side and rubber on the other, and is used to wipe
or rub off ink and foreign materials from the nozzle surface.

Pump motor (stepping motor)
The pump motor runs normally (the pump wheel turns clockwise as viewed from the
pump wheel side) and reverses (the pump wheel turns counterclockwise) to execute the
following functions:

Cap assembly

Table 2-7. Explanation of Operation (continued)

When not printing, the print head (should) rest on the cap assembly to ensure that
the nozzles don't clog. Also, the print head is in the capped position during ink
charging, cleaning, and so on.

Flushing box
Flushing (dummy printing) is performed over the flushing box, and the flushed ink
flows through the pipe to the waste ink pads.

Operation
•

Wiping Operation

The carriage is moved from right to left along the rubber side of the
wiper (the right half of the wiper plate) incorporated in the pump unit so
that the head surface is rubbed with the rubber of the wiper.
Purpose:
• Before ink suction, removes the ink and other substances adhering to
the head surface.
• Ensures close contact of the cap.

Rubbing Operation

The carriage is moved from left to right along the felt side of the wiper
(the left half of the wiper plate) incorporated in the pump unit so that
the head surface is rubbed with the felt of the wiper.
For easy removal of adhering substances, the nozzle surface is wetted
before rubbing operation by suction of a small amount of ink.
Purpose:
• Removes ink and other substances adhering strongly to the head
surface.
• Ensures close contact of the cap.

Capping

In order to prevent the ink viscosity from increasing while it is being
kept, a rubber cap is placed over the print head nozzles when entering a
shutdown operation.

CR Lock Mechanism
If the carriage moves from the printable area to beyond the capping (CR_HOME)
position to the right, the carriage moving prevention lock is engaged. The CR lock
mechanism uses the cutter solenoid in common. When the cutter solenoid goes ON
in the capping position, the CR lock is released.

Explanation

Carriage (CR) Lock

• This is the carriage stop position when the power is Off.
• The time when the carriage is in the standby position (home position)
with the power On and with no paper loaded and no print data to
print.

Ink Initial Filling

Flushing

Explanation

Empty Suction
Operation

After ink is sucked up, the remaining ink inside the cap is sucked up
and the ink adhering to the head nozzle surface is removed.
• Through flushing, etc., the ink that has accumulated in the cap is
sucked up and discharged.

• This is the operation where the head is filled with ink for the first
time. When the first ink cartridge is inserted (after all 6 colors have
been inserted), the ink initial filling operation is performed
automatically.
• The initial filling flag is set when the printer is shipped from the
factory, then after this operation, the initial filling flag is reset. The
initial filling flag is also set after the “ Input Rank” (p232) is run.
• In order to prevent the viscosity of the ink inside the head nozzles
from increasing, the ink inside the flushing box is flushed out.
• Flushing is done when paper is set, when printing from the standby
state, during continuous printing, during paper Eject, during paper
cutting, etc.

2.4 Outline of Power Supply Circuit Board

There are three control signals between the C472MAIN Board and the Power Supply
Circuit Board. Table below describes details of the control signals:

The 100 V AC power from the wall outlet is supplied via the power cable, an accessory
of Stylus Pro 7600/9600, into the Inlet of the printer and to the Power Supply Circuit
Board.

Table 2-10. Control Signals between C472MAIN Board and Power Supply Board

The power switch constitutes a secondary power switch system. The secondary power
switch system operates as follows: even with the power switch turned off, the Power
Supply Circuit Board is operating by a slight power as long as the power cable is
connected.

C A U T IO N

Even after the power switch is turned off, the Power Supply Circuit
Board does not stop operating immediately, but power is kept on
until the ink system ending sequence is completed.
Do not disconnect the power cable or do not shut off power by
turning off any power switch other than that on the printer.

power cable from the outlet and disconnect the interface cable.

C A U T IO N

Only the specified printer tools should be used so as to maintain

3.1.1 Introduction
First of all, when performing troubleshooting, the following basic parts should be
checked.
1.

Look in the printer for any foreign matter and make sure there is nothing there
to hinder normal operation.
2. Carry out printing by setting the printer in the “Pause” state, then press the
[SelecType] button 2 times. Next using the [Paper Feed] switch in the “TEST
PRINT MENU,” select “STATUS CHECK”, then press the [Enter] switch
and print.
From the status sheet, you can Check to see if the cause of the trouble is that
the printer (either the printer unit itself or some major unit) is at the end of its
service life, and check the user inherent panel settings, etc.
3. There should be no market soiling of the outside or the inside of the printer. If
it is extremely soiled, carry out cleaning.
4. Each of the units and parts in the printer should not be missing or damaged,
and should have the normal shape and configuration.
5. Each of the harnesses should be undamaged, and should be correctly
connected to the relevant connector (perpendicularly and in the correct
direction).
6. Each cam and gear in the printer mechanism should have no uneven wear or
be overly worn, and the combinations should be correct.
7. Each type of rubber roller in the printer mechanism should be cleaned and it
should be ascertained whether the cause of the trouble is because of dirt or due
to some other cause.
8. Each type of rubber roller in the printer mechanism should not be unevenly
worn or excessively worn, and their combinations should be correct.
9. As necessary, initialize the NVRAM on the C472MAIN Board (return the
individual customer settings and panel settings to the factory settings).
Carry out initialization by executing “INIT. NVRAM” from the “CLEAR
COUNTERS MENU” in “Maintenance Mode 2."

3.3.1 Dot Missing
If the printer is kept for a long time without being used, the viscosity of the ink on the
nozzle surfaces of the print heads, and in the nozzles themselves, increases, and may
cause skipping of dots during printing. In such cases, execute Power cleaning (p.55) in
SelecType mode first (execute several times). If normal printing is not recovered even
after this power cleaning, check the following particulars.

3.3.2 Uneven Printing/Poor Resolution

3.3.3 Smudged or Marred Printout (Front)

If the print quality is abnormal (uneven printing, diffused image, etc.), the following
items should be checked.

If smudging or marring occurs due to rubbing by the head, etc. on the paper's printed
surface, check the following items.

Adjust the gap
In the SelecType (p.30) or the Self-diagnostic Function (p.219) menu, carry out
gap adjustment (“Gap Adjustment (Bi-D Adjustment, Uni-D Adjustment) (p.55)”
and “Bi-D Alignment Adjustment (p.247)”).

If the trouble occurs only when the user is using a specific type of paper (thick
paper), carry out “User Paper Setting” using the panel setting procedure.
(By setting the information concerning the thickness of the paper the user is using
and correcting the print position (correction of changes in the position where ink
hits the paper surface due to differences in paper thickness), avoid influencing the
print position.)

If smudging is occurring at the front end of the roll paper or at the rear end, widen
the margins at the front end and rear end. (Set the “Roll Paper Margin” front end
and rear end on “15 mm”.)
(If high duty printing was done close to the front end and rear end (margin = 3
mm), the paper will contain a large amount of ink and deformation of the paper
will be accelerated, and depending on the case, the paper will touch the heads.)

If paper with weak edges which cannot move smoothly along the paper path is
being used, Select “NORM” for “SUCTION” in the “PAPER CONFIG. MENU”,
which is in the “Panel Settings”.

If there is rubbing and smudging due to slow drying in printing of user paper.

If the this problem occurs after replacing the Main Board with a new one:

Set the stand basket paper Eject direction on Front.
In the item “DRYING TIME” in the User Paper Setting Menu”, in “Panel

• Transfer the backup parameters on the old Main Board to the new board.

(p.217)

Settings,” set the drying time (the time until auto paper cutting is carried out
after printing is finished. (Default: 0 second; Maximum: 10 seconds)

• Execute “Write D/A Correction Values” in the diagnostic mode.(p.235)

If the printer's condition is not improved by the above items (adjustments), check
the following items using the self-diagnostic function.

Head Slant Adjustment (p.245)
C H E C K
P O IN T

Once you have made the “Head Slant Adjustment”, be sure to make
the “Bi-D Alignment Adjustment (p.247)” and “Gap Adjustment
(Bi-D Adjustment, Uni-D Adjustment)” (p.55).

Troubleshooting

If the trouble cannot be resolved by the above methods, check the following.

The cap assembly / tension spring is off.
(If this spring comes off, cap will collect inside the cap and ink that adheres
around the head nozzle surface ends up adhering to the paper.
Check to see if dust containing ink, foreign matters or paper is adhering to the
side surface of the head.

3.3.4 Smudged or Marred Printout (Reverse side)
If smudging or marring of the paper back surface with ink occurs, the following items
should be checked.
1.

Check to see if there isn't ink adhering to the paper feed path. If there is ink
adhering, it should be wiped off.

3.3.5 White or Black Banding in the carriage running
direction
If white or black banding (uneven density) in parallel with the carriage running
direction appears on your printout, check the following points:
1.

Sub-platen A/B Surface
Grid roller surface
Paper guide L surface
Paper guide L2 surface

Dot missing
Head ID setting value

One likely cause of ink adhering to the above parts is the following cause.

If dot missing is found, execute head cleaning. (If deemed necessary, select and
execute “Power cleaning (p.55)” in the SelecType mode or “Cleaning (p.258)” by
self-diagnostic function.)If the Head ID value is wrong, set the correct value.

Nozzle Check Pattern Printing (p.40)
Select “Adj: Check Nozzle” in the Adjustment (p.229) menu by the self-diagnostic
function.
Check the following points:

Adjustment
If dot missing is not found, perform the following adjustments and check for
improvement:

Paper feed correction (driver)
Head Slant Adjustment (Mechanical Adjustment) (p.246)
If each line of nozzles in the head is perpendicular to the carriage running
direction correctly, the raster lines printed with nozzles can overlap or be
dislocated, so that black banding (uneven density) or white banding (blank
spaces between raster lines) may occur.
If the adjustments above do not work enough to improve the quality, try to improve by
executing Feed Correction + T&B Adjustment (p.238) by the self-diagnostic
function.

Any adjustments required after disassembling the units are described under the heading
“ADJUSTMENT REQUIRED”. Be sure to make the specified adjustments by
referring to Chapter 5 “ADJUSTMENT”.
When you have to remove any units or parts that are not described in this chapter, refer
to the exploded diagrams in the appendix.

4.1.1 Precautions
Before proceeding with any disassembly or assembly work, make absolutely sure of
the following.

Disassembly & Assembly

Summary

The power switch for Stylus Pro 7600/9600 is incorporated in
the secondary circuit of the power supply circuit. Therefore, the
printer is always supplied with electric power, unless the power
cable is disconnected. Before servicing, unless otherwise stated,
be sure to unplug the power cord from the wall outlet to
prevent injury, burn, and electric shocks or damage to the
circuit. In doing so, be sure to turn the printer off and wait
several seconds first and then unplug the power cord. If you
must keep the power supplied to measure voltage, be aware of
the potential for electrical shock and do all tasks with the most
care.
With the front cover open, the cover sensor stops the operation
of the CR motor and PF motor. To ensure safety, you are
prohibited from disabling this interlock function.
A lithium battery for memory backup is installed on the main
circuit board of Stylus Pro 7600/9600. To prevent accidents
caused by the battery, never fail to observe the following
instructions when serving the main circuit board:
• Keep the battery away from any metal or other batteries so
that electrodes of the opposite polarity do not come in
contact with each other.
• Do not solder on any part of the battery. (Doing so may result
in leakage of electrolyte from the battery, burning or
explosion. The leakage may affect other devices close to the
battery.)
• Do not charge the battery. (This may cause burning or
explosion.)
• Do not dismantle the battery. (The gas inside the battery may
hurt your throat. Leakage, burning or explosion may also be
caused.)
• Do not short-circuit the terminals of the battery. Do not put
the battery on a conductive table in such a way that the
terminal face comes in contact with the table.
• Do not remove and install the battery. Do not install the
battery in the wrong direction.
• Do not heat the battery or put it near fire.

Danger of explosion if the battery is incorrectly replaced.
Replace only with the same or equivalent type recommended by
the manufacture. Dispose the used batteries according to
government's law and regulations.
Wear protective goggles to protect your eyes from ink. If ink
gets in your eye, flush the eye with fresh water and see a doctor
immediately.
Wear a pair of gloves to protect your hands from the sharp
edge in the printer mechanism.
If ink comes into contact with your skin, wash it off with soap
and water. If irritation occurs, contact a physician.

Avant de commencer, assurez vous que l'imprimante soit

nouvelle respecte bien les caracteristiques requises.

Lorque que vous installez la pile au lithium, faites attention a
l'inserer dans le bon sens en respectant la polarite.
Veillez a jeter les piles usagees selon le reglement local.
Ne rechargez pas les piles au lithium.

Risque d’explosion si la pile est remplacée incorrectment. Ne
remplacer que par une pile du même type ou d’un type équivalent
recommandé par le fabricant. Eliminer les piles déchargées selon
les lois et les règles de sécurité en vigueur.

Summary

make sure you have enough space. If you need to move the
printer, make sure the space you move to is safe.
Because the printer is much heavier than most printers you
need to take extra care. If you need to take apart the printer
and the stand from each other or put then together, two people
are necessary.
If you remove and replace any parts of the ink path system, be
sure to discharge the ink beforehand by executing “Ink
Blowing” in “Clean Head” process.
Refer to “5.2.3.20 Clean Head (p.255)”.
After removing any of the ink related parts, double check to
make sure all parts are secured; otherwise you're going to be in
big trouble.
Use only recommended tools for disassembling, assembling or
adjusting the printer.
Apply lubricants and adhesives as specified.
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 boards, be careful
concerning static electricity which can cause damage to the
board. It is recommended you use an anti-static wrist band or
similar grounding device to prevent static electricity buildup.
Stylus Pro 7600/9600 uses many FFCs (Flexible Flat Cables).
Improper connection, such as slanting insertion, of an FFC can
cause a short circuit resulting in broken elements on the circuit
board. Be sure to connect the FFCs to the connectors properly
with great care.

Revision C

In reassembly, place the wiring of electric parts in specified

Top

positions. (If wiring is located in places other than specified,
cables can come in contact with a sharp edge or the anti-noise
margin may lessen.)
As necessary, if you remove each cover and operate the printer,
care should be taken not to get injured by the operation of the
drive system units.
The cutter blade is extremely sharp, so care should be taken
not to injure yourself when handling it.
An ultra-hardened blade is used for the cutter blade, and
physically, it is extremely brittle material, so care should be
taken not to bump it against any of the metal parts of the
printer, etc. and damage it.
When performing service operations on items which are
controlled as after service parts but which no procedures have
been provided for, the state of the parts should be observed
closely before beginning the operation to get a thorough idea of
how to proceed.
If you have to loosen a screw that has blue screw-lock applied
to its head, make sure you apply blue screw-lock again when
reassembling.

4.4.3.1 Assembly Procedure for the PF Loop Scale ASSY
When assembling the PF loop scale unit, the following exclusive tool should be used.

Exclusive tool No.#F730

: FPF Loop Scale Assembly Base
(Code: 1051765)

Protective backing

The assembly procedure is shown below.
1.

Set the exclusive tool, #F730 as shown in the figure below, then set the PF loop scale
base part with the double sided tape side facing up.

Peel the protective backing off the double sided tape to the PF loop scale base.

Affix the PF loop scale carefully to the PF loop scale base with the PF loop scale
printed surface downward, aligning it precisely with the PF loop scale base.

Peel the protective backing off the other side of the double sided tape and affix the tape
so that it is within the black circle on the unprinted side of the PF loop scale ASSY.

of the PF loop scale.

There is no problem if the PF loop scale's affixing position on
the PF loop scale base deviates somewhat. The important

4.4.3.2 PF Loop Scale ASSY Affixing Procedure
Double sided tape

When assembling the PF loop scale unit, the following exclusive tool should be used.

Exclusive tool No.#F731

: PF Loop Scale Affixing tool
(Code: 1051767)

Protective backing

The assembly procedure is given below.
1.

Set the PF loop scale ASSY's double sided tape side on the grid roller side, align the
internal diameter of the PF loop scale with the left end of the grid roller (PF roller) and
set it lightly.

C A U T IO N

At this point, the PF loop scale ASSY should not be fitted on the
grid roller as far as it can go. If the PF loop scale ASSY is placed on
the grid roller by hand, it could damage the PF loop scale ASSY's
internal diameter and the distance from the center of the grid roller
to the scale reading part would not be the same all around any
more, resulting in a drop in the encoder sensor's reading accuracy.

Figure 4-55. Affixing the Double Sided Tape to the PF Loop Scale

Press the exclusive tool #F731 against the PF loop scale ASSY from the outside, then
insert the grid roller in as far as the base plate carefully, and affix it.

C A U T IO N

With this function, all the processing except for some items are
executed on the assumption that roll paper is used. Take care,
since even sheets, if loaded, are handled as roll paper.
During execution of this function, detection of remaining
volume in ink cartridges and Maintenance Tank is not
performed. Therefore, when you execute this function for print
head replacement or any other work which requires
consumption or discharge of a large volume of ink, check the
remaining volume in ink cartridges and Maintenance Tank
beforehand. (If you neglect this checking, the capacity of the
Maintenance Tank can be exceeded so that ink may flow out;
never forget to perform this checking.)

PROCEDURE FOR HEAD GAP ADJUSTMENT (UNI-D ADJUSTMENT)
1.

Start the Self-diagnostic Function:

Power OFF → [Paper Feed ∆] + [Paper Feed ∇]+[Cut/Eject] → Power ON

Display “Adj: Uni-D”:
[Paper Feed ∇] → [SelecType >] → [Paper Feed ∇] x11

Print the pattern.
[SelecType >] →[Enter ↵] when “[Enter] Adjust Print” is displayed
(See Figure 5-55)

Check the pattern:
Make certain that the black lines and color lines are not out of alignment.
When they are not out of alignment, leave the head gap adjustment mode by pressing
[SelecType >] two times. If they are out of alignment, follow the instructions given
below:

If out of alignment
1. Select the gap item in question:
Select “Gap 240,V1”, “Gap 240,V2” or “Gap 190,V4” by means of
[Paper Feed ∇] and enter the adjustment menu for the selected item by pressing
[SelecType >].
2. Adjust the color position in question:
Select the relevant color by means of [SelecType >], and in consideration of
the printed pattern, input the compensation value on the panel.
Shift direction (black line as reference):
(Compensation setting: in increments of 1/2880 inch)
Shift to the right = Input a (+) value
Shift to the left = Input a (-) value
3. Check again:
Check the pattern output again, and when the lines are in alignment, leave the
head gap adjustment mode by pressing [SelecType >] two times. If the lines are
out of alignment, repeat inputting a value.
C H E C K
P O IN T

Even when you have left the head gap adjustment menu, you can
display the menu for an relevant item by means of [SelecType >].
Therefore, there is no need of outputting the comprehensive
patterns again.

5.3.1 Overview
This section describes the mechanism adjustments you need to perform when
mechanical parts have been replaced or removed. The relationship between parts and
required adjustments are as follows.

This adjustment is necessary for service operations that require you to remove/loosen
the CR Motor or CR Steel Belt. When replacing or re-installing the CR Steel Belt, you
need to confirm the tension of the CR Steel Belt. Tighten or loosen the screws on the
Driven Pulley to increase or decrease the tension.

No special tools are required.

toward you (to the “paper holding” position). (See Figure 5-66)
At this point, if the value on the LCD is not “01”, loosen the screw securing the
mounting plate for the P_THICK_0.3 Sensor (left). Then slide the mounting plate to a
position where the LCD shows “01”, tighten the screw and remove the 0.4-mm
thickness gauge.

Set the 0.3-mm thickness gauge the same way as above and make certain that the value
on the LCD is “00”.
At this point, if the value on the LCD is not “00”, loosen the screw securing the
mounting plate for the P_THICK_0.3 Sensor (left). Then slide the mounting plate to a

5.3.7.1 Paper Cutting Position Check
Check the paper cutting position which has been adjusted as instructed in the previous
section, by cutting paper actually.

Cutter Positioning Adjustment
1.

Set paper (minimum size: about 10 cm wide x 20 cm) in the paper path along the paper
setting position on the right side of the printer, then move the paper set lever to the
front to hold the paper.

Move the CR manually to the right edge of the paper, then lower the cutter manually.

While holding the bottom edge of the paper with one hand, cut the paper with the
cutter.

set a gauge with minimum measuring units of 0.5 mm at the edge of the cutter level
difference on the sub-platen and check if the distance from the edge of the cutter level
difference to the actual paper cutting position is within 0.5 mm (+0.1/–0.2mm).

If the measuring results are outside the standard, loosen the 3 screws holding the paper
guide L, then carry out fine adjustment of the paper guide L’s assembly position.

P O IN T

Paper
Carriage

The length from the edge of the cutter level difference to the
front edge of the paper where it was actually cut should be
within 0.5 mm (+0.1/–0.2mm).
If you are adjusting the assembly position of the paper guide L,
the installation screws that are loosened should be the absolute
minimum number of screws necessary to adjust the position. If
a large number of screws is loosened, the assembly position of
the paper guide L will shift a great distance from the original
adjustment position, so caution should be exercised.

Loosen the one screw securing the PF Encoder Sensor, then put the round hole of the
PF Encoder mounting jig on the PF Roller Shaft and fit the notched end against
contour of the PF Encoder Sensor's emitter (outside).

Move the PF Encoder Sensor up and down so that it is in a position where the
clearance between the contour of the PF Encoder Sensor and the notch in the PF
Encoder mounting jig becomes uniform, then tighten the one screw securing the PF
Encoder Sensor.

MAINTENANCE

EPSON Stylus Pro 7600/9600

Revision C

6.1 Overview

C A U T IO N

This section explains necessary maintenance items and their details for this product.
Basically for this product, service technicians are required to visit the user’s location
where the EPSON Stylus Pro 7600/9600 is used, and perform necessary maintenance/
service on-site while following the precautions below. Service technicians have to be
extra careful not to cause any accident to the product or the user’s environment.

W A R N IN G

Since the power switch is mounted on the secondary circuit of

the power supply circuit, unless otherwise specified, always
turn off the printer using the power switch. After all moving
parts have stopped, wait several seconds and then disconnect
the power cable from the AC plug socket to prevent electric
shock or circuit damage during service operations.
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.

A lithium battery is installed on the MAIN Board of this
printer. Be sure to observe the following instructions
when servicing the battery:

Keep the battery away from any metal.
Do not install the battery in the wrong direction. (This may cause
burning or explosion.)

Do not heat the battery or put it near fire.
Do not set the C472 MAIN board directly on top of any object
which is conductive.

Be careful not to let ink get into your eyes or your skin. If ink
gets in your eye, rinse them immediately with water.

Maintenance

Overview

When performing service and maintenance operations,
sufficient space should be assured surrounding the place where
the work is performed.
The printer should be set in a place where there is no vibration,
and where it is level and stable.
This machine is extremely heavy, so adequate caution should
be exercised when handling it. (If you are taking or reinstalling
the body and stand, there should be 2 or more persons doing
the work.)
If operations are performed which involve the removal of ink
system parts, there is danger of the product or the floor, etc. in
the place where it is installed becoming soiled, so sheets, etc.
should be spread on the floor, etc. during the work o removing
parts related to the ink channels.
If you are handling electrical circuit boards, to prevent
destruction of the elements by static electricity, the elements on
the board should not be touched with bare hands. If necessary,
take the necessary measures to prevent static discharge, such as
wearing a ground strap, when performing such work.
If you are removing the various covers and operating the
printer in that state, adequate caution should be used so as not
to be injured by high speed operating parts such as the PS fan.
The cutter blade is extremely sharp, care should be taken not to
be injured by it.
The an ultra-hardened blade is used for the cutter blade, and
materially, this item is extremely brittle, so it should not be
bumped against any metal or other parts on the printer when
handled.
If the printer that has already been installed needs to be packed
and transported again, first make certain that the print head
has been capped properly with the power to the printer turned
off. Then remove all the ink cartridges and install all the
packing materials as referred to in the Start-Up Guide or
Assembly and Setup Guide supplied with the printer.

6.1.1 Periodic Maintenance Items and Product Life
Information
Periodic Maintenance Items
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 Table 6-1 for parts which require
periodic replacement.

Product Life Information
Table 6-1 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.

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.
