Memory Stick/PRO, SD/MMC and xD-Picture Card shares the same slot.
When cards are inserted in the two slots at once, the slot which will be accessed first is determined according to the priority shown in the table.
To select a card that has been inserted in a non-active slot, first remove the card in the active slot.
In memory card direct printing mode, the image files in the active slot are valid and have assigned frame numbers. The number of images will not change if a card is inserted in another
nonselected slot.
When the card inserted in the slot is accessed from the PC, only one drive is displayed at a time as a removable disk* and only the card that is in the active slot can be accessed via the
removable disk. A card that has been inserted into a non-selected slot cannot be accessed.
(This is for Windows. For Macintosh, the card in the active slot will be mounted on the desktop.)
Does not support 5V type of memory cards.
When a memory card is being accessed, do not touch the memory card.
For detailed information on the supported file system and formatting the memory card, refer to “ 1.7.2 Memory Card Direct Print Function ( p. 31 ) ”.

A trimming function is provided as a means of coordinating an image with the
types of photo frames handled by the printer. This function is always activated so
that the image fits within the photo frames.
This function is described briefly below.
The printed photo frame and an image to be printed are matched in length along
one side and the image is resized along the perpendicular side to fit the frame on
that side. Any part of the image that does not fit within the photo frame is trimmed
away (not printed).

2.1.3 Printhead
D4-CHIPS Turbo2 type printhead is employed, which produces variable sized dot and
economy dot. The printhead configuration is as follows.

Therefore, whenever the printhead, main board, or the printer mechanism must be
replaced with a new one, the Head ID of the new printhead needs to be written into the
EEPROM using the Adjustment Program. The printer generates appropriate PZT drive
voltage based on the Head ID information.

Nozzle configuration

Following explains the basic components of the Printhead.

Black: 90 nozzles x 1
Color: 90 nozzles x 3 (cyan, magenta, yellow)

PZT
PZT is an abbreviation of Piezo Electric Element. Based on the drive waveform
generated on the main board, the PZT selected by the nozzle selector IC on the
printhead pushes the top of the ink cavity, which has ink stored, to eject the ink
from each nozzle on the nozzle plate.

Filter
This filter is located beneath the ink supply needle which supply ink to the
printhead from the ink cartridge. The filter is preventing dirt or dust from getting
into the printhead. Any dirt or dust may interrupt normal ink flow or can cause
nozzle clog adversely affecting the print quality.

The basic operating principles of the printhead, which plays a major role in printing,
are the same as the previous printer; on-demand method which uses PZT (Piezo
Electric Element). In order to reduce unit-to-unit variation in ink droplet size, the
printhead has its own Head ID (16-digits code for EPSON Stylus CX7300/CX7400/
DX7400/NX200/TX200/TX203/TX209/SX200/SX205 and Stylus CX8300/CX8400/

2.1.3.1 Printing Process

2.1.3.2 Printing Method

This section explains how the printhead of the on-demand inkjet printer fires ink drop
from each of the nozzles.

EPSON Stylus CX7300/CX7400/DX7400/NX200/TX200/TX203/TX209/SX200/
SX205 and Stylus CX8300/CX8400/DX8400/NX400/TX400/TX405/TX409/SX400/
SX405 offers printing with variable sized dot or printing with economy sized dot.

When not firing ink drop
When the printing signal is not output from the C690 main board, or the PZT drive
voltage is not applied, the PZT does not change its shape. Therefore, the PZT does
not push the ink cavity. The ink pressure inside the ink cavity is kept normal. (refer
to Figure 2-6 (p.45) “When not firing ink drop”)

When firing ink drop
When the print signal is output from C690 main board, the nozzle selector IC
provided on the printhead transmits the data in 1-byte unit. Based on the drive
voltage generated on the main board, the PZT selected by the nozzle selector IC
pushes the top of the ink cavity. By this operation, the ink stored in the ink cavity
is ejected from nozzles. (refer to Figure 2-6 (p.45) “When firing ink drop”)
Ink path

PZT

Variable dot mode
This mode is developed to improve the print quality on Epson designated paper.
Three sizes of dot; micro, middle, and large are automatically selected and used
for printing according to the print data, basically the same as conventional models.
Superior quality can be achieved on the Epson paper.
Economy dot mode
Fixed larger dot is used for printing in economy mode, which enables fast printing
with lower resolutions.

2.1.4 Carriage Mechanism

the CR mechanical load is in the initial state and saved into the EEPROM.
According to the variations measured in the sequence, the voltage is corrected to
make the drive current value constant reducing an individual difference.

The carriage mechanism components include the carriage unit (including printhead,
CR encoder sensor), CR motor, timing belt, and CR scale.
The operating principles of the carriage mechanism are described below.
Main Frame

CR Scale

CR Encoder Sensor

CR measurement sequence
To set the appropriate drive voltage for the CR motor in accordance with variation
of the CR motor mechanical load, the printer runs a CR measurement sequence
and stores the measured data into the EEPROM at power-on or in an ink cartridge
replacement sequence. A fatal error occurs if the printer detects that too much load
is applied to the CR motor.

CR Motor

The above control and sequences enable to correct the drive voltage for the CR motor
based on the mechanical load and the electrical characteristic of the motor. According
to the corrected drive voltage, heating value of the motor is calculated. The printer
automatically provides wait time per CR path during printing when the predetermined
heating value is reached.

2.1.4.2 Carriage Home Position Detection
Like the previous model, the carriage home position is detected by the CR motor drive
electric current and carriage speed/position signals sent from the CR encoder. The
detection sequence performed at power-on is described below.
Timing Belt

Carriage Unit

Figure 2-7. Carriage Mechanism
2.

2.1.4.1 CR Motor Control
This printer employs closed-loop control, via the CR motor and an encoder, to control
the carriage speed and position. Since the CR motor is DC motor, the printer controls
the motor in the following methods in order to ensure stable print quality.
Heat control
The heat control over the CR motor is carried out based on the electrical
characteristic of the motor such as torque constants, coil resistance and power
supply voltages.

Drives the CR motor to move the carriage until it contacts with the right
frame, and then stops the CR motor. The carriage position is set as a position
specified number of counts rightward from the home position.
Moves the carriage again to the carriage lock position to check the lock for
proper operation.
The printer starts to monitor the carriage position through the CR encoder.

The printer causes a fatal error if too much load on the CR motor is detected due to
obstruction on the carriage path or if no carriage position information is obtained due to
CR encoder or CR scale failure.

CR motor drive dispersion measurement sequence
Variations in torque constant, coil resistance and power supply voltage of the
motor are measured in a CR motor drive dispersion measurement sequence when

2.1.5 Paper Loading/Paper Feed Mechanism
The paper loading/feed mechanism are driven and controlled by the PF motor (DC
motor) and the PF encoder.
The PF motor drive force is transmitted to the LD roller and the PF roller via the gears
in the mechanism. In the loading mechanism, paper is fed to the PF roller from the ASF
unit, and the feed mechanism transports the paper during printing and ejects it.

The PE sensor detects the paper top and bottom edges during the loading and feeding
operations. When the sensor could not detect the top edge of paper during the loading
operation, the printer causes a paper out error. And when the sensor could not detect
the bottom edge of paper during feeding operation, the printer causes a paper jam error.

2.1.5.1 Paper Loading Mechanism (ASF Unit)

STEP1: ASF HOME POSITION

The paper loading mechanism loads paper from the ASF unit and feeds paper to the PF
roller. The ASF unit includes the hopper, change lever, LD roller shaft, and clutch
mechanism.
The change lever and the clutch mechanism play an important role in the paper loading
operation as described below.
1.

ASF home position detection function
The change lever and the clutch mechanism are used to detect the ASF home
position.
The counterclockwise rotation of the PF motor brings the change lever to engage
with the clutch mechanism. The ASF home position is detected by the engagement
of the change lever at the beginning of the paper loading operation. At this time,
paper is not fed to the PF roller because the PF motor drive force is not yet
transmitted to the LD roller shaft.

The counterclockwise rotation of the PF motor pinion gear (as seen from the left of the
printer) causes the change lever to push down on the clutch lever, and the clutch lock
tab is disengaged from the clutch gear as shown in Figure 2-9. This cuts the PF motor
drive transmission to the LD roller shaft, and the shaft does not move at all. At the
same time, the hopper is pushed down by the two cams on the LD roller shaft, and the
paper back lever is set at the position to prevent paper from being fed. The “ASF home
position” indicates all of the above statuses.

STEP2: RELEASING CLUTCH LEVER TO DRIVE LD ROLLER

STEP3: FEEDING PAPER FROM ASF

When the PF motor pinion gear starts clockwise rotation (as seen from the left side),
the change lever is moved toward the front of the printer to release the clutch lever.
This causes the clutch to engage with the gear by being pulled by the extension spring.
The clutch gear engages with the clutch lock tab and the PF motor drive force is now
can be transmitted to the LD roller shaft.

After the engagement of the clutch, the PF motor pinion gear starts counterclockwise
rotation (as seen from the left side) and the drive force is transmitted to the LD roller
shaft via the clutch lock tab and the clutch gear. When the LD roller starts to rotate, the
paper back lever is returned to its standby position, and the hopper is released from the
cams by being pushed by the spring. This causes paper to be caught between the
hopper and the LD roller, and the further rotation of the LD roller feeds the paper into
the printer.

STEP4: ENDING PAPER LOADING OPERATION
Continuous counterclockwise rotation of the LD roller (as seen from the left side) feeds
paper to the PF roller. The LD roller rotation causes the hopper release cam and the
paper back lever cam to push down the hopper and the paper back lever respectively.
The paper back lever returns paper to the standby position to prevent multiple sheets of
paper from being fed at once.
When the LD roller and the clutch reach the ASF home position shown in “Step1” on
the previous page, the clutch lever is locked again by the change lever. This causes the
PF motor drive force not to be transmitted to the paper loading mechanism and to be
transmitted only to the paper feeding mechanism.

2.1.5.2 Paper Feed Mechanism
The major components of the paper feed mechanism are the PF motor, PF roller, EJ
(paper eject) roller, PE sensor, PF encoder sensor, and PF scale. The sheet of paper fed
from the ASF unit is nipped between two rollers to be transported during printing and
to be ejected.
1.

The first two rollers used for feeding the paper are the PF roller and the paper
guide roller mounted on the upper paper guide unit. The PF motor drive force is
transmitted to the paper guide roller via the PF roller.

The next two rollers are the EJ roller and the star wheel roller mounted on the Star
Wheel Holder Assy. The PF motor drive force is transmitted to the star wheel
roller via the EJ roller.

The figure below shows how the PF motor pinion gear drive force is transmitted to the

2.1.6 Ink System Mechanism

2.1.6.1 Capping Mechanism

The ink system mechanism includes the cap mechanism and the pump mechanism.
And the capping mechanism includes the carriage lock mechanism and the wiping
mechanism. The table below describes the function of each mechanism.

The capping mechanism incorporates the wiping mechanism, however, the two
mechanisms operate independently. Capping the printhead is performed by the carriage
movement as the conventional models (such as Stylus CX4900/CX5000/CX6000) do.

Cap Slider protrusion

When the cap slider pops up, its protrusion is disengaged from the groove of cam (2).
Therefore, the clutch is engaged causing the cam to rotate together with the combination
gear.

In the non-cleaning state, the cap slider protrusion secures the cam and the clutch of
the combination gear is disengaged. Therefore, the PF motor drive force is not
transmitted to the cam.

PF motor CW rotation: Moves the Wiper Upward

PF motor CCW rotation: Moves the Wiper Downward

The counterclockwise rotation of the PF motor rotates the cam in counterclockwise
direction to move the wiper downward, which is out-of position for cleaning.

The clockwise rotation of the PF motor rotates the cam in clockwise direction
to move the wiper upward to clean the head.

2.1.6.4 Pump Unit Mechanism
The PF motor drives the pump unit mechanism as well as the paper loading/feed
mechanisms. The motor drive force is always transmitted to the pump unit. (It is also
transmitted to the LD roller via the clutch mechanism and the change lever.)
The rotational direction of the PF motor changes the pump unit operations as shown in
the following table.

2.1.7 Ink Sequence

Initial ink charge
When the printer power is turned On first time after purchase, the initial ink charge
is automatically carried out to fill the ink cavity in the printhead with ink. The
initial ink charge flag in the EEPROM is cleared when the initial charge is
completed successfully. EPSON Stylus CX7300/CX7400/DX7400/NX200/
TX200/TX203/TX209/SX200/SX205 and Stylus CX8300/CX8400/DX8400/
NX400/TX400/TX405/TX409/SX400/SX405 requires about 120 seconds at
maximum for the initial ink charge. If the power is turned Off during the process,
the printer automatically runs a CL3 at the next power-on.

Periodic flushing
Reduces viscosity of ink inside the nozzles during printing.

Manual Cleaning
EPSON Stylus CX7300/CX7400/DX7400/NX200/TX200/TX203/TX209/SX200/
SX205 and Stylus CX8300/CX8400/DX8400/NX400/TX400/TX405/TX409/
SX400/SX405 offers three types of manual head cleaning (CL1, CL2, and CL3)
that can be run from the control panel. They delete air bubbles in ink, clear nozzle
clogging, or to eject foreign materials.
CL1, CL2, and CL3 are performed in that order when the cumulative print time
has not reached 9 minutes regardless of the number of print paths counted since
the last CL. When 9 minutes has reached or exceeded, only CL1 is executed.
In the case that any of the ink cartridges has almost run out or completely run out
of ink, the LED flashes or light and the manual cleaning is disabled.
Timer Cleaning
Like the previous printers, this printer does not have lithium battery which is used
for the backup power source for Timer IC. So, this printer manages the printer off
period or cleaning cycle by using the following method.
The printer driver sends the timer command (time data) to the printer before
printing. The command is generated based on the PC's timer and it consists of
year, month, date, hour, minute and second. As soon as the printer receives the
timer command, the printer stores the command in the EEPROM and compares it
with the latest CL time which has been stored in the EEPROM. When the time
difference exceeds the predetermined time period, the printer automatically runs
the timer cleaning and stores the date and time of the cleaning in the EEPROM.
Flushing
The following two types of flushing is carried out automatically.

Pre-printing flushing
Reduces viscosity of ink inside the nozzles before starting printing.

The major components of the scanner mechanism of EPSON Stylus CX7300/CX7400/

DX8400/NX400/TX400/TX405/TX409/SX400/SX405 are the scanner carriage unit
and the scanner motor.

2.2.1 Scanner Carriage Mechanism
2.2.1.1 Scanner Carriage Unit Overview
The Scanner Carriage Unit is constructed of a CIS Board (including linear CCD), Rod
Lens Array, LED (light source), etc.
CIS Board
CIS Board contains the sensing elements that are placed across the entire width of
an original. The sensing elements, which does not install a color filter, read an
original through the Rod Lens Array by turning on red, green, and blue lightemitting diodes (LEDs) alternately. It is not the CIS Board but the Main Board that
converts the analog light signal read by the Rod Lens Array into digital signal.
Rod Lens Array
A number of rod-shaped lenses, which are arranged on the sensing elements, are
also placed across the entire width of an original. These lenses read the light
reflected from the original that is produced by the light source (LEDs) and pass the
information to the sensing elements. Compared to conventional CCD method, this
optical system allows the focal length (distance between sensor and image
scanned) to be shallow. Therefore, an original to be scanned should be brought
close to the document glass. The optical system, in addition, is 1:1, (there is no
optical reduction or enlargement) and this results in a scanner offering the solid
performance in terms of accuracy.

Three color LEDs (the three colors being red, green, and blue) illuminate the line

2.2.1.2 Scanner Carriage Unit Movement Overview
Scanning image is performed in the main scan direction (=1 line) by the CIS board and
in the sub-scan direction (=several lines) combined with Scanner Carriage Unit
movement. (refer to the figure below) The CIS board can scan 1 line in main scan
direction (parallel to the Scanner Carriage Unit) by one time. When scanning next lines
after the second line in sub-scan direction, CR driving moves the Scanner Carriage
Unit, and scan the other lines. The scanned data is sent to the control board. The
scanned data for “n” lines and “n-1” line are processed consecutively.

3.1 Overview

3.1.2 Preliminary Checks

This chapter describes how to solve problems.

Before starting troubleshooting, be sure to verify that the following conditions
are all met:

W A R N IN G

C H E C K
P O IN T

Be careful to avoid electric shocks when checking the electrical
circuit boards (C690 MAIN and C687 PSE/PSB boards) while
the power is turned on.
Touching an FET, transistor or heat sink with one hand while
touching a metal part of the mechanism with the other hand
could result in an electric shock, so carefully avoid this.
After initial filling of ink has been repeated several times,
immediate moving or tilting of the printer could result in
leaking of ink that has not been completely absorbed by the
Waste Ink Pad. When initial filling of ink has been repeated
several times, check the ink remaining in the tip of the Waste
Ink Tube and the waste ink not absorbed by the Waste Ink Pad
before moving the printer.
Disassembly and reassembly of parts is often required when
identifying the causes of problems. The parts should be
disassembled and re-assembled correctly while referring to
“DISASSEMBLY/ASSEMBLY” (p.90) so that the operation
and status of each check item can be correctly verified.
Some individual part and units may require adjustment once
they are removed or replaced. If removing or replacing parts
which have specific instructions for adjustment included in
“DISASSEMBLY/ASSEMBLY” (p.90), be sure to make these
adjustments after repairing the problem location.

Adjustment Program.

5.1.1 Servicing Adjustment Item List
The adjustment items of this product are as follows.
Table 5-1. Adjustment Items
Adjustment Item

Purpose

Method Outline

Tool

Readout the EEPROM data from the main board before removing it.
Then replace the board with a new one, and load the EEPROM data to
the new board.

• Adjustment Program

EEPROM data copy

When the main board needs to be replaced, use this to copy adjustment
values stored on the old main board to the new board. If this copy is
completed successfully, all the other adjustments required after replacing the
main board are no longer be necessary.

Initial setting

This must be carried out after replacing the main board to apply settings for
the target market.

Select the target market. The selected market settings are
automatically written to the main board.

• Adjustment Program

USB ID input

This sets a USB ID of the printer. A computer identifies the printer by the ID
when multiple same models are connected via a USB hub.

Enter the product serial number of the printer. The ID is automatically
generated and written to the main board.

• Adjustment Program

This must be carried out after replacing the Printhead in order to enter the
new Printhead ID (Head ID) that reduces variation between Printheads.

Enter the ID printed on the Head QR code label attached on the
Printhead. The correction values are automatically written to the main
board.

• Adjustment Program

TOP margin
adjustment

This corrects top margin of printout.

A top margin adjustment pattern is printed. Examine the lines printed
near the top edge of the printout, and enter the value for the line that
is exactly 3 mm away from the top edge.

• Adjustment Program
• Ruler

First dot position
adjustment

This corrects left margin of printout. The print start position in the carriage
moving direction is corrected by software.

A first dot adjustment pattern is printed. Examine the lines printed
near the left edge of the printout and enter the value for the line that is
exactly 5 mm away from the left edge.

• Adjustment Program
• Ruler

Head angular
adjustment

This must be carried out after replacing the Printhead in order to correct tilt
of the Printhead by software.

A head angular adjustment pattern is printed. Examine the printed
lines and enter the value for the most straight lines.

• Adjustment Program

This corrects print start timing in bi-directional printing to improve the print
quality.

A Bi-D adjustment pattern is printed. Black and color patterns are
printed for each of the five dot sizes (ECO, VSD1, VSD2, VSD3,
VSD4). So, there are 10 groups. Examine the patterns and enter the
value for the pattern with no gap and overlap for each mode.

• Adjustment Program

Initialize PF
deterioration offset

This resets the counter to maintain paper feed accuracy which decreases due
to paper dust.

Reset the counter to its default.

• Adjustment Program

Disenable PF
deterioration offset

When reading the counter value from the old main board is impossible in the
case of replacing the board, use this to set the counter to its maximum value.

Set the counter to tis maximum value (10000).

• Adjustment Program

CR motor heat
protection control

This must be carried out for efficient heat control of the CR motor.
Electrical variation of the motor and the power supply board are measured to
acquire correction values for them.

Select the parts that you replaced. The correction values are
automatically written to the main board.

enter the value for the best pattern to register the correction value to
the printer.
(Carry out the procedure for each color.)

• Adjustment Program

This corrects variations in paper feed accuracy in the band print mode to
achieve higher print quality.

A PF band adjustment pattern is printed. Examine the printout
patterns and enter the value for the best pattern to register the
correction value to the printer.

• Adjustment Program

In order to improve the throughput, the printer minimizes the number of
print passes when printing on the bottom margin (bleed) in the borderless
printing. This may cause white area to appear on the bottom edge of the
borderless printout. In such case, use this adjustment to correct the printing
range on the bottom margin (bleed).

A bottom margin adjustment pattern is printed. Examine the printout
patterns and enter the value for best pattern to register the correction
value to the printer.

6.1 Overview

6.1.2 Service Maintenance
If any abnormal print (dot missing, white line, etc.) has occurred or the printer indicates
the “Maintenance request error” (This error is displayed as “Service Required” in the
STM3), take the following actions to clear the error.

This section provides information to maintain the printer in its optimum condition.

6.1.1 Cleaning
This printer has no mechanical components which require regular cleaning except the
Printhead. Therefore, when returning the printer to the user, check the following parts
and perform appropriate cleaning if stain is noticeable.
C A U T IO N

Never use chemical solvents, such as thinner, benzine, and
acetone to clean the exterior parts of the printer like the
Housing. These chemicals may deform or deteriorate the
components of the printer.
Be careful not to damage any components when you clean
inside the printer.
Do not scratch the coated surface of the PF roller. Use a soft
brush to wipe off any dusts.
Use a soft cloth moistened with alcohol to remove the ink stain.
When using compressed air products; such as air duster, for
cleaning during repair and maintenance, the use of such
products containing flammable gas is prohibited.

Exterior parts
Use a clean soft cloth moistened with water, and wipe off any dirt. If the exterior
parts are stained by the ink, use a cloth moistened with neutral detergent to wipe it
off.
Inside the printer
Use a vacuum cleaner to remove any paper dust.

6.1.2.1 Printhead cleaning
When dot missing or banding phenomenon has occurred, you need to perform the
Printhead cleaning operation* by using the Printhead cleaning function. This function
can be performed by the control panel operation, the printer driver utility and the
Adjustment program.
* : EPSON Stylus CX7300/CX7400/DX7400/NX200/TX200/TX203/TX209/SX200/
SX205 and Stylus CX8300/CX8400/DX8400/NX400/TX400/TX405/TX409/
SX400/SX405 have three modes for manual cleaning, and even during printing, the
appropriate cleaning mode is automatically selected and performed according to
various conditions. Therefore the ink consumption amount for manual cleaning
varies depending on each mode.

6.1.2.2 Maintenance request error
Ink is used for the Printhead cleaning or cap flushing operation as well as the printing
operation. When the ink is used for the Printhead cleaning or flushing operation, the
ink is drained via the pump to the Waste ink pads. The amount of the waste ink is
stored as the waste ink counter into the EEPROM on the Main Board. Due to this,
when the waste ink counter has reached the limit of the absorbing capability of the
Waste ink pads, the Maintenance call error is indicated on Status monitor 3. However,
the limit value of the waste ink counter varies according to the usage.
C H E C K
P O IN T

LD Roller
When paper loading function does not operate because friction of the LD roller is
lowered by any paper dust, use a soft cloth moistened with alcohol to remove the
paper dust.

Refer to following chapter about indication of the maintenance
request error.
Chapter 3 TROUBLESHOOTING (p.58)

When the maintenance request error has occurred, replace the waste ink pad with new
one and clear the waste ink counter stored into the EEPROM. If the waste ink counter
is closed to its limit, we recommend to replace the Waste ink pad with new one. This is
because the Maintenance request error will may occur after returning the repaired
product to the customer.
