Operating Principles Overview 16
2.1 Overview
This chapter explains the operating principles of the mechanical sections and
electrical circuits in this product. The main components of this product are as
follows.
Control circuit board : C589 MAIN
Power supply circuit board : C589 PSB
Control panel board : C589 PNL
Control panel B board : C589 PNL-B
2.2 Printer Mechanism
Like the conventional model, this product uses DC motors and stepping motors
as power sources. The following table describes the motor types and their
applications.
The basic mechanism is almost same as the Stylus Photo R800.
The most major difference is that this Stylus Photo R1800 is equipped with a
dedicated sensor to detect a open or close status of the Front Cover.
This prevents the Print Head from damaging by mistake.
The schematic diagram below shows the printer mechanism.
Figure 2-1. Printer Mechanism Outline
Table 2-1. Motors
Motor Name Type Applications/Functions
CR Motor DC motor with
brushes
Used for carriage driving. Makes little noise
during driving. The CR linear scale and CR
encoder sensor are used to control the motor.
PF Motor DC motor with
brushes
Drives the Paper loading rollers at the time of
fixed-value paper loading or paper feed/eject
operation. To grasp the paper feed pitch, the
precision gear surface is fitted with the PF scale
and the PF encoder sensor is used to control
the motor.
APG Motor DC motor with
brushes
Drives the Carriage Unit at the time of PG
setting. The two APG Sensors and Carriage
Shaft are driven vertically to control the motor.
ASF Motor 4-phase, 48-pole
PM type
stepping motor
Drives the paper feed operation of the ASF.
Since this is a stepping motor, any scales or
photo sensors to know the driving conditions are
not required.
Pump Motor 4-phase, 48-pole
PM type
stepping motor
Drives the pump, wiper, etc. of the Ink System.
Since this is a stepping motor, any scales or
photo sensors to know the driving conditions are
not required.

Operating Principles Printer Mechanism 17
2.2.1 Carriage Mechanism
The Carriage mechanism consists of the Carriage Motor (CR Motor), Carriage
Shafts, Platen Gap Adjustment Mechanism, Carriage Lock Mechanism, and
others.
2.2.1.1 Carriage Mechanism
The following indicates the specifications of the CR motor (DC motor) that
drives the Carriage.
Closed loop control based on the CR Motor (DC Motor) and CR Encoder
Sensor has advantages in stabilized print quality and silent operation.
Heat Generation Control
The printer has a machanism to reduce the variations in the torque
constant and coil resistance of the DC motors, and variations in output
voltage of the Power Supply Board to obtain a designated heating value.
CR Variation Measurement Sequence
The variations mentioned above are measured in a CR variation
measurement sequence when the CR mechanical load is in the initial
status and saved into the EEPROM (A6<H>). According to the saved
information, the printer controls the drive voltage to obtain a designated
driving current. This minimizes the unit-to-unit variation.
CR Measurement Sequence
To set the appropriate drive current value according to the CR mechanical
load, the mechanical load is measured in a CR measurement sequence
and saved into the EEPROM A4<H>, A5<H> at power-on or after
replacement of the Ink Cartridge (s). However, if 6E is saved at the
EEPROM A4<H> and 05 at A5<H>, Fatal error will occur since too large
load is applied to the CR drive system.
The above control and sequences correct the drive current value of the CR
Motor according to not only the mechanical load but also the variations of the
motor and like. In addition, the resultant CR drive current value is used to
calculate a heating value, and when the specified heating value is reached,
wait time is provided per CR path for printing.
Table 2-2. CR Motor Specifications

Operating Principles Printer Mechanism 18
2.2.1.2 Carriage Home Position Detection
As in the conventional model, the Carriage Home Position is detected using the
drive current of the CR Motor and the speed/position signal of the CR Linear
Encoder.
The basic home position detection sequence is as described below.
1. The CR linear encoder pulse counter in the CPU is reset by the
initialization operation performed at power-on.
2. When the CR Motor rotates counterclockwise, the Carriage Unit moves
from left to right. When the following conditions are satisfied, the CPU
assumes that the Carriage Unit made contact with the right frame.
The ASIC detects 1158/1500 counts or more in the PWM output under
CR Motor load positioning control.
P1 (number of output pulses from when power is switched on until the
Carriage Unit makes contact with the right frame) is 19 steps or less.
3. When the CR Motor rotates clockwise, the Carriage Unit moves from right
to left. When the following conditions are satisfied, the CPU assumes that
the Carriage Unit reached the CR lock confirmation position.
The ASIC detects 575/1500 counts or more in the PWM output under
CR Motor load positioning control.
A difference between P1 and P2 (number of output pulses from when
the Carriage Unit made contact with the right frame until it reaches the
Carriage lock confirmation position) is 19 steps or less.
4. When the CR Motor rotates counterclockwise to move the Carriage from
left to right and the CPU detects 1158/1500 counts or more in the PWM
output under CR Motor load positioning control, the printer judges that the
Carriage moved to the far right position (is in contact with the right frame ).
5. When a difference between P1 and P3 (number of output pulses from
when the Carriage Unit reached the Carriage lock confirmation position
until it makes contact with the right frame) is 4 steps or less, the printer
judges that the Carriage Unit is in the home position.
The IC14 (ASIC) sets the drive current value adequate for the Carriage Unit
motion and outputs it to the motor driver.
Based on the signal output from the IC14 (ASIC), the IC5 (Motor Driver)
outputs the CR Motor drive current to the CR Motor.
2.2.1.3 Sequence Used for PW Detection
The PW (paper width detection) Sensor installed on the Carriage Unit bottom is
used to control the printer according to various sequences.
The following briefly describes the PW Sensor operating principle.
A dark voltage is measured by the PW Sensor in three places at the right flat
area (area without the absorber) on the Front Paper Guide every time the
printer is turned on, and the measurement values are saved into the EEPROM
as threshold values.
Threshold value detection voltage: Paper present
Threshold value detection voltage: Paper absent
The following sequences are performed.
Detection of Left and Right Edges of Paper and Control
Before Printing
The printer detects that paper has been loaded. And it sets the print
range according to the paper-size information from the Driver and the
actual paper-size detected by the PW sensor.
During Printing
When executing a borderless printing, the printer sets the off-range
margins by detecting the paper edges with the PW Sensor. And when
the resolution is 1440 x 1440 (VSD3) or 2880 x 1440 (VSD3) dpi, the
printer performs the Off-Range Thinning Out Control to make a further
correction to the off-range margins.
Detection of Top Edge of Paper and Control
Before starting a print job, the printer detects the top edge of a loaded
single sheet of paper, roll paper, or board paper to set the off-range top
margin. (Only when not detecting the top edge of paper with the PW
Sensor.)
Detection of Bottom Edge of Paper and Control
After starting a borderless printing, the printer sets the off-range bottom
margin.
Detection of Edges of CD-R and Control
Before starting to print, the PW Sensor detects top, bottom, left and right
edges of the CD-R. See Section 2.2.3.4 CD-R Printing Mechanism on
page 24.

PW sensor dark voltage (VH) measurement
PW sensor dark voltage (VH) measurement is performed at the following
timings and locations and used to calculate the threshold value of whether
paper is present or not.
Cut sheets, Roll paper
The dark voltage is measured and updated at every power-on, and the
threshold value (VS) is calculated and saved in the EPROM area as a
PW detection level.
•Threshold value detection voltage: Paper present
•Threshold value detection voltage: Paper absent
CD-R Tray
When printing on a CD-R, the dark voltage is measured on the CD-R
tray, and the threshold value (VS) is then calculated and saved in the
EPROM area as a PW detection level.
•Threshold value detection voltage: CD-R present
(tray home position detected)
The measurement voltage in the presence of the CD-R is saved into
the EEPROM as a white level. The white level value is used to check
the sensor deterioration condition during servicing or like.
• If the measurement value of the white level is close to that of the PW
detection level, it means that the sensor is dirty or deteriorated.

2.2.3.1 ASF Paper Feeding Mechanism
The following shows the specifications of the stepping motor that drives the
ASF Assy.
Driven by the ASF Motor, the ASF Assy performs the following feeding
operation.
1. When a paper feeding command is issued from the PC or the Paper Switch
of the panel is pressed after power-on, the driving force of the ASF Motor
begins to be transmitted to the LD Roller following the route shown below.
2. When the LD Roller starts rotating, the Flag of the ASF Sensor Wheel
comes free from the notch on the ASF Sensor. And at the same time, the
Paper Back Lever becomes free from the Cams located at the left and right
ends of the LD Roller, then the Paper Holder on the Paper Back Lever
inclines downward by tensile force of the Paper Back Lever Torsion Spring.
3. By the LD Roller's rotation, the Hopper is released from the Hopper Cams
located at the left and right ends of the LD Roller, and the Hopper pops up
by tensile force of the Hopper Compression Spring.
4. When the next sheet of paper is fed by the LD Roller and the Retard Roller,
the Hopper is pressed against the Frame again by the Hopper Cams. And
the Paper Holder of the Paper Back Lever rises by the Cams at the left and
right ends of the LD Roller to prevent the next sheet from being fed with the
previous sheet.
5. The LD Roller stops to rotate when it makes one revolution and the Flag of
the ASF Sensor Wheel returns to the ASF Sensor.

2.2.3.2 Roll Paper Feeding
When selecting the Roll Paper Mode, the contol Panel switches function in
different ways from when printing other than roll paper. This section describes
the deifference.
1. The roll peper is fed into the printer after a lapse of three seconds from
when the PE sensor detects the paper.
2. The roll paper is fed backward to be set at the print position.
While the printer is performing the above operation, the switches are disabled.
After the roll peper is set to the print position, the switches operation becomes
defferent from when printing other than roll paper.
The details of the difference are described below.
When Loading Roll Paper.
Pressing the Roll Paper Switch for more than 3 seconds feeds the leading
edge of the roll paper backward to the PE Sensor (the Paper LED flashes).
In this state, draw the roll paper and press the Paper Switch to return the
panel operation to the normal mode that enables paper feeding from the
ASF.
When Received a Print Job for Roll Paper
1. After finished the print job, press the Roll Paper Switch.
2. A cutoff line is printed, and the roll paper is fed to the roll paper cut
position.
3. After cutting the roll paper with a pair of scissors or like, press the
Roll Paper Switch again. This returns the leading edge of the
paper to the print starting position.

2.2.3.3 CD-R Tray Base Lock Mechanism
To prevent the Print Head from being damaged by mistake, the printer is
designed to lock the CD-R Tray Base when the Carriage Unit is out of its home
position.
The following explains the lock mechanism of the CD-R Tray Base.
Lock Release Sequence
1. When the Carriage Unit returns to its home position, the Pump
Motor drive is transmitted to the Paper EJ Lock Release Cam.
2. The salient of the Cam presses down the Paper EJ Transmission
Lock Lever to release the tab of the Paper EJ Lock Lever from the
Paper EJ Transmission Lock Lever.
3. The CD-R Release Lever comes free from the Paper EJ Lock
Lever and comes down to enable the CD-R Tray Base to open.
When the Carriage Unit is out of its home position, the salient of the Paper EJ
Lock Release Cam does not press down the Paper EJ Transmission Lock
Lever, and the tab of the Paper EJ Lock Lever is not released. Therefore, the
CD-R Tray Base cannot be opened.

2.2.3.4 CD-R Printing Mechanism
CD-R Tray Home Position Detection Sequence
The following sequence is performed after opening the Front Cover (CD-R
Sensor closing), inserting the CD-R Tray to the specified position, and
pressing the Paper SW.
When the close signal of the CD-R Sensor is detected, no paper is fed
from the ASF if the Paper Switch is pressed. In this case, the Paper Switch
executes a CD-R Tray home position detection sequence.
1. When the APG Assy is driven, the PG position is set to "++" and
the Driven Roller of the Upper Paper Guide presses the CD-R
Tray.
2. When the Carriage Unit moves leftward and the PW Sensor
detects the CD-R, the Carriage Unit returns to its home position
(HP).
3. After waiting for about 5 seconds at the HP, the Carriage Unit
moves to the CD-R Tray HP detectable position (right end of the
CD-R Tray).
4. The CD-R Tray is pulled in the ASF direction, the PW Sensor
detects the CD-R Tray HP, and then the Carriage Unit moves to
the center of the CD-R Tray.
5. When the PW Sensor detects the white marking in the center of
the CD-R Tray, the CD-R Tray is fed in the paper ejection
direction.
6. The Carriage Unit moves leftward, the PW Sensor detects the left
side white marking, then the Carriage Unit moves rightward, and
the PW Sensor detects the right side white marking.
7. The Carriage Unit moves to the center of the CD-R Tray, and the
PW Sensor starts detection in the back-and-forth direction of the
CD-R. After the leading edge of the CD-R is detected, the CD-R
Tray is fed in the paper ejection direction, and the trailing edge of
the CD-R is detected. After that, the CD-R Tray is fed to the center
of the CD-R in the paper ejection direction.
8. The Carriage Unit moves leftward, and the PW Sensor starts
detection in the horizontal direction of the CD-R. After the left end
of the CD-R is detected, the Carriage Unit moves rightward, and
the right end of the CD-R is detected.
9. The Carriage Unit moves to the CD-R Tray HP detectable position
and stops there, and then the CD-R Tray is fed in the ASF
direction.
10. When the CD-R Tray stops operating, the Carriage Unit moves to
the carriage HP and stands by.
If the CD-R Tray HP, white marking or CD-R cannot be detected within the
steps predetermined for the CD-R Tray HP detection sequence, the CD-R Tray
is ejected and Paper Out Error is displayed.

When the printer is in a standby status or its power is OFF, the Cap Unit
prevents the ink from thickening.
The following figures shows the Cap Unit operation.
Figure 2-11. Capping Mechanism
2.2.6 Ink Sequence
The following ink sequence is executed according to various timer, counter,
flag and other information saved on the EEPROM.
CSIC-related sequence
The ink type code stored in the CSIC Memory Chip is saved in the Main
Board EEPROM. At power-on, data is read from each color CSIC and the
CSIC data status becomes valid. If the data read from each CSIC has any
problem, No Ink Cartridge, CSIC Error or Ink Out will be displayed.
After CSIC operation is checked, the ink consumption of the I/C currently
installed per color is compared with the ink consumption saved in the
printer EEPROM, and control is performed under the following conditions.
When the current ink consumption data differs between the Ink
Cartridge and the EEPROM
1. The printer judges that the Ink Cartridge was replaced while the
printer was turned off. Then it resets the 1st I/C flag in the
EEPROM.
2. The printer updates the number of times the CSIC is installed.
3. After incrementing the counter of I/C replacement, the printer
reads the ink consumption data from the CSIC to write it over the
existing data in the EEPROM following the CSIC data replacement
sequence.
4. The printer model name data on the CSIC is rewritten.
Note:The reason why the model name data is rewritten from the printer
to the CSIC is to know for which model was the I/C used at the
time of collecting used I/Cs.
5. The replacement flag 2 (flag that indicates CL after Replacement)
is set and the CL is executed.
Slider cap rises to perform
capping.

EPSON Stylus Photo R1800/R2400 Revision B
Operating Principles Printer Mechanism 29
When the current ink consumption data in the Ink Cartridge and that in
the EEPROM is same
1. When the initial filling flag is set and the CSIC ink consumption is 0,
the printer judges that initial filling is not yet performed.
(The printer before initial filling judges that the I/C is fitted in a
power-off status.)
2. Installation count updating, CSIC information rewriting, and initial
filling are executed in that order.
3. If the initial filling flag is not set, the printer judges that I/C(s) has
not been replaced during power-off and regards the current CSIC
data as valid.
Data is written to the CSIC at the following timings.
At power-off
When starting the power saving mode
When replaced an Ink Cartridge(s)
At the time of cleaning
1. Reads the data from the CSIC.
2. Compare the date with the ink consumption data in the EEPROM.
3. If the EEPROM data is same as the CSIC data, ends the
sequence. If they differ, the difference is added to write the sum in
the CSIC.
Initial Ink Filling
When the printer is powered on for the first time after purchase, the printer
executes the initial ink filling operation to fill the ink cavities of the Head
with ink. When the initial ink filling operation is performed properly, the
printer clears the flag in the EEPROM so that initial ink filling operation will
not be performed when it is powered on the next time. The Stylus Photo
R1800 requires about 160 seconds to perform the initial ink filling
operation.
If the sequence does not end normally during initial filling, the initial filling
flag is not cleared and the CL operating flag is set. Because of these flags,
when powered on the next time, the printer assumes that it was powered
off for some reason during initial filling and executes CL3 instead of the
initial filling sequence. (On the conventional mode, initial filling was
executed again. However, when this operation was performed, ink was
wasted and therefore CL3 is executed to cover the ink filling performance.)
When the initial filling flag is set and the CL operating flag is not set, the
printer judges that the initial filling was not executed at all (power was
switched on but the cartridges were not installed), and when the printer is
powered on the next time, it executes initial filling.
Replacement Cleaning
Replacement CL1 is executed when replaced an Ink Cartridge(s).
Amount of Ink Suction
Replacement CL1: 3.09g (0.386g per color)
EPSON Stylus Photo R1800/R2400 Revision B
Operating Principles Printer Mechanism 30
Manual Cleaning
This printer provides three different manual cleanings to remove ink
coagulated by air bubbles, viscous material or foreign matter. Perform the
following manual CL operations by operating the panel or using the utility
included in the printer driver.
Independently of the printing path after the previous CL, perform manual
CL from CL1 to CL3 in order if the cumulative printing timer counter is less
than 7min. Only when the cumulative printing timer counter is more than
7min, execute only CL1.
Amount of Ink Suction
•CL1: 1.55g (0.194g per color)
•CL2: 4.08g (0.510g per color)
•CL3: 6.47g (0.809g per color)
Wiping Operation
Clean the nozzle surface with the right-half rubber part of the wiper.
Flushing Operation
Prevent color mixture. Stabilize the ink surface inside the nozzles.
In addition, the printer determines which CL to perform according to the
remaining amount of ink in the Cartridge. When the printer detects the
amount is low, it automatically choose the CL that uses ink less than the
other CLs. If the remaining amount of ink is extremely low (Ink Low or Ink
Out status), the printer disables the all manual Cleanings and indicates the
status on the EPW3.
Timer Cleaning
Ink is consumed depending on the combination of the cumulative printing
timer, cumulative cleaning count and cleaning timer.
Flushing
There are two types of flushing.
Flushing before printing
This is performed to reduce the viscosity of ink in the Print Head
nozzles before starting to print.
Scheduled Flushing
This is performed to prevent ink in the Print Head nozzles from
increasing its viscosity during printing.
2.2.7 Power-On Sequence
The following describes the printer operation after it is powered on.
When the Carriage Unit is in the Home Position with the CR Locked
1. After power-on, the drive of the APG Motor is transmitted to the Carriage
Shaft, and the PG position changes from PG Typ. to PG++.
2. The drive of the CR Motor is transmitted to the Carriage Unit, and the
Carriage Unit performs HP detection operation in the following path.
Home position ⇒ Right frame ⇒ CR Lock confirmation position
⇒ Right frame ⇒ Home position
3. The drive of the Pump Motor is transmitted to the Cap Unit, the Cap opens
(lowers), and the CR Lock is released.
4. After the Carriage Unit has moved leftward by the specified number of
steps, the Wiper, driven by the Pump Motor, performs the following.
Wiper setting ⇒ Wiper resetting
5. The Carriage Unit returns to the home position, and the PG position
returns from PG++ to PG Typ.
6. The drive of the PF Motor is transmitted to the PF Roller and Paper Eject
Rollers (front and rear), which then rotate for about 2 seconds.
7. After moving between the left and right frames twice, the Carriage Unit
moves to the right end of the Front Paper Guide.
8. The PF Roller and Paper Eject Rollers (front and rear) rotate.
Rotation for about 4 seconds (slow speed) ⇒ Rotation for about 2
seconds
9. The Carriage Unit returns to the home position and is secured by the CR
Lock.
EPSON Stylus Photo R1800/R2400 Revision B
Operating Principles Electrical Circuit Operating Principles 31
When the Carriage Unit is Out of the Home Position
1. When the PG position is other than PG++ after power-on, the drive of the
APG Motor is transmitted to the Carriage Shaft, and the PG position
changes to PG++.
2. The drive of the CR Motor is transmitted to the Carriage Unit, and the
Carriage Unit returns to the home position at slow speed.
3. The drive of the PF Motor is transmitted to the PF Roller and Paper Eject
Rollers (front and rear), which then rotate for about 2 seconds.
4. After the Carriage Unit has moved leftward by the specified number of
steps, the Wiper is set, driven by the Pump.
5. After the Carriage Unit has returned to the home position, it moves leftward
again by the specified number of steps. And, driven by the Pump Motor, ink
is sucked for about 4 seconds and then the Wiper is set, and the CR Lock
is placed.
6. The Carriage Unit performs HP detection operation in the following path.
Home position ⇒ Right frame ⇒ CR Lock confirmation position
⇒ Right frame ⇒ Home position
7. The drive of the Pump Motor is transmitted to the Cap Unit, the Cap opens
(lowers), and the CR Lock is released.
8. The Carriage Unit returns to the home position, and the PG position
returns from PG++ to PG Type.
9. The PF Motor drive is transmitted to the PF Roller and the Paper EJ
Rollers (front and rear) to rotate them for about 2 seconds.
10. The Step 7 to 9 of "When the Carriage Unit is in the Home Position with the
CR Locked (p30)" are performed, and the Carriage Unit is locked.

5.2.4.1 Overview of the Colorimetric Calibration
Purpose
Measuring the color of the ink discharge amount information and
registering/controlling this information improves calibration accuracy and
ensures consistent color quality.
To reduce unit-to-unit and mode-to-mode variations in color.
To improve the accuracy of the Ink Counter.
The Color ID can improve the Ink Counter accuracy, which reduces the
running cost of ink.
Colorimetric Calibration Technology
The Principle
The ink discharge amount characteristic of a printer is measured by
measuring color difference (L*a*b*) of a printed chart with a calibrator.
Created Color ID information based on the obtained L*a*b values is
stored on the printer. When printing, the printer sends the Color ID to
the printer driver to compensate the number of ink droplets (dot
generation rate) for each of nine1 different sized droplets of each color.
This method allows mass-produced printers to provide consistent print
quality reducing unit-to-unit variation.
Example: Compensation of Ink Amount Ejected from a Print Head
(dot generation rate)
•When the standard printer generates ten dots.
If the ink discharge amount is insufficient by 10%, this is compensated by
generating 11 dots.
Note 1: Three different sized droplets (small, medium, large) for each of three
waveforms (VSD1, 2, 3)
Head ID
In the conventional color calibration with a Head ID, the print head
characteristics (weight of discharged ink) are measured and
compensated. The following shows the correlation between
conventional Head ID adjustment and Colorimetric Calibration.
Calibrator Scanning Ruler
White
Reference
Tile Calibration Plate
CHECK
P O I N T
As color measurement is performed with the fully assembled
product, the electrical characteristics which are unique to
each Main/Power Board are also compensated in addition to
the Print Head.
Clear file
EPSON Stylus Photo R1800/R2400 Revision B
Adjustment Adjustment 148
Note : Calibration processes of "Color ID" and "Head ID" are exactly the same.
Calibration can be made by transmitting the ID to printer drivers and changing
dot generation rate in reference to the same calibration table.
Supplement: Regarding remaining ink amount
When the Ink Counter detects ink out, a certain amount (safety margin) of
ink is still remaining in the cartridge to prevent the print head from
damages caused by printing without ink. This safety margin is important
especially for a ptinter that discharges larger amount of ink.
The figure below illustrates the concept of this safety margin.
Figure 5-20. Concept of Remaining Ink Amount
Table 5-6.The Difference in Calibration Method between Head ID and
Colorimetric Calibration.
Conventional Head ID adjustment Colorimetric Calibration
In the print head manufacturing
process, ink discharge amount of
each head is actually measured to
get individual charateristic
information. The information is
stored on the printer as Head ID to
control the print head.
By printing and measuring a color
chart, a variation from the standard
machine is obtained and registered
as the correction value (Color ID) to
control the amount of ink droplets.
CHECK
P O I N T
Make sure not to confuse Head ID with Color ID.
Head ID
An ID information specific to individual print head. It is
indicated on the Head QR Code Label attached to the
print head.
Color ID
An ID information specific to individual printer. It is
obtained by the Colorimetric Calibration.
C A U T I O N
Before performing Colorimetric Calibration, the conventional
Head ID must be pre-registered. This is because the Head ID
contains information to create a waveform to drive the head,
which is also required for the Colorimetric Calibration.
C A U T I O N
If you do not perform Colorimetric Calibration after
performing Head ID adjustment, the printer will be controlled
only by the Head ID, which affects the following.
Ink Counter
The ink consumption counter table switches from the
table for Color ID to the one for Head ID. This change
causes an ink out error to occur 2 to 5 percent earlier
than when using the table for Color ID.
Color Quality
Color quality will be at the same level as that of printers
adjusted by the conventional Head ID, and the same
color quality as mass-produced printers cannot be
maintained.

5.2.4.2 Adjusting Method of the Colorimetric Calibration
When color measurement is performed at the same place as the repair work

a place different from the repair work site, calibration is performed by separate
processes. The following illustrates the overall workflow.

MAINTENANCE
EPSON Stylus Photo R1800/R2400 Revision B
Maintenance Overview 173
6.1 Overview
This section provides information to maintain the printer in its optimum
condition.
6.1.1 ROM Replacement
This printer may require the ROM to be replaced when the program is changed
or added. In such cases, use the special tool (ROM puller: 2035659 (#F749)) to
replace the ROM. The position of the ROM is shown in the figure below.
Figure 6-1. ROM Location
6.1.2 Cleaning
This printer has no mechanical components which require regular cleaning.
Therefore, when returning the printer to the user, check the following parts and
perform appropriate cleaning if stain is noticeable.
Housing
Use a clean soft cloth moistened with water and wipe off any dirt. If the
Housings are stained with ink, use a cloth moistened with neutral detergent
to wipe it off.
Inside the printer
Use a vacuum cleaner to remove any paper dust.
C589 Main Board
ROM
C A U T I O 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 degrade or
deteriorate the quality of this product.
Be careful not to damage any components when you
clean inside the printer.
Do not scratch the surface of the PF Roller assembly.
Use a soft brush to wipe off dust.
Use a soft cloth moistened with dilute alcohol to remove
ink stain.
Do not use the supplied cleaning sheet for normal
usage. It may damage the coated surface of the PF
Roller. If the adhesive surface of the cleaning sheet is
set to the ASF LD Roller side and used to clean the ASF
LD Roller surface, it is no problem.

Maintenance Overview 174
6.1.3 Service Maintenance
If print irregularity (missing dot, white line, etc.) has occurred or the printer
indicates "Maintenance Error", take the following actions to clear the error.
6.1.3.1 Head Cleaning
The printer has a built-in head cleaning function, which is activated by
operating the control panel.The procedure is given below.
1. Confirm that the printer is in stand-by state.
Check that the Power LED is not flashing.
2. Hold down the Ink Switch on the control panel for more than 3 seconds.
The Power LED flashes during the cleaning sequence.
6.1.3.2 Maintenance Request
Ink is used for printing and Head Cleaning. Waste ink is drained into the Waste
Ink Pads via the Cap Unit, and its amount is stored into the EEPROM's
Protection Counters (Waste Ink Counter) A and B (located near the home
position or the opposite side). When the preset value is reached, the Waste Ink
Counters detect that the Waste Ink Pads have reached the absorption limit.
The printer displays "Maintenance Request" to request the Waste Ink Pads to
be replaced.
Protection Counter A+B Limit
Up to 17772
Timing for Replacing the Waste Ink Pads
When the Protection Counter reaches the value shown above, a
Maintenance Request is indicated, and the printer disables all switches
except the Power switch.
Since the Protection Counter value can be confirmed in the adjustment
program, be sure to check the value when servicing regardless of
whether the service is related to the Waste Ink Pad or not. If the
Protection Counter value of that printer is close to its limit, inform the
user about that, and replace the Waste Ink Pads and reset the
Counters with the user’s permission. (If the Waste Ink Pads are not
replaced at that time, it is expected that the printer will be returned for
repair in the near future due to a Maintenance Request error.)
Under the specific conditions, the limit level of the counter is preset to
25000 pages for black ink or to 10000 pages for color ink. We assume
that the limit level will be reached in about 3 years in normal use.
Replacement Procedure
Replacement of Waste Ink Pads in Disassembly and Assembly
(Refer to 4.2.2 "Waste Ink Pad" on page 80.)
After the Replacement
Reset the Protection Counter (Refer to Chapter 5 "ADJUSTMENT")
CHECK
P O I N T
For Head Cleaning, it is recommended to run the nozzle
check and the cleaning alternately to minimize ink
consumption.
