1.3.2.3 Multi-slot operations
Overview
There is only one type of card that can be used to simultaneously access both
a connected computer and the direct printing function.
The slots have assigned priority to determine which slot will be accessed first
when cards are inserted in several slots at once.
To select a card that has been inserted in a non-active slot, the card in the
active slot must first be removed.
• Direct printing
Only 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 also inserted in
a non-selected slot.
• Connection to computer (Windows)
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.
• Connection to computer (Macintosh)
Only the card in the active slot can be mounted on the desktop. A card that
has been inserted into a non-selected slot cannot be mounted on the desktop.
Details
Access priority
The access priority among slots is assigned as:
1: CF (Microdrive)
2: SmartMedia/xD-Picture Card
3: Memory Stick (Memory Stick PRO)/SD (MMC)
Slot selection when power is turned on
If cards are inserted in several slots when the power is turned on, the active
slot is determined by the priority ranks listed above.
Example: If Smart Media and Memory Stick are both inserted at power-on,
the SmartMedia slot becomes the active slot.
Slot selection after power is turned on
When a card is removed from the active slot, the slot with the next-highest
priority becomes the active slot (if a card has been inserted into it). There is no
need to re-insert any card before accessing it. If no slots contain any cards, the
highest-priority slot (CF Microdrive) again becomes the active slot.
Cards can be removed from non-selected slots in any order.
Example: If a memory stick and CF card are inserted while SmartMedia is
selected, CF becomes selected (active) once SmartMedia is
removed.

The file system used by the card reader function depends on the host’s specifications.
For a detailed description of the DCF specifications, see the “Design Rule for Camera
File System Standard, DCF Version 2.0, JEIDA-CP-3461”.
1.4.1.2 Media format
Media must be formatted according to the DCF Version 1.0 or 2.0 standard.
DOS FAT formats (FAT12, FAT16) and single partition (basic partition)
1.4.1.3 File formats
The file formats supported by this unit are described below.
JPEG files (*.JPG)
These are photo data files that comply with the Exif Version 2.21 standard. (Exif
version 1.0/2.0/2.1/2.2/2.21)
Camera specification files (*.MRK)
These are definition files used when in camera specification mode. An
“AUTOPRINT.MRK” file whose full path name is no longer than 32 characters is
valid.
PRINT Image Framer (P.I.F.) definition file (*.USD)
File to define the layout in accordance with the PRINT Image Framer
specifications. Files only in the “¥EPUDL¥” directory are available. Compatible
with Print Image Framer Rev.2.1.
PRINT Image Framer (P.I.F.) definition file (*.FD2)
File to define the layout in accordance with the PRINT Image Framer
specifications. All files in the memory card are targeted for search.
Compatible with Print Image Framer Rev 3.1.
File contents are divided into complete type and template type.
Template type: The frame only on which image data is printed is specified.
Provides nearly identical functions as those supported with
the current P.I.F. Rev.3.1.
Complete type: Print layout information, image data and frame data is
contained in one package. Printing is performed using this file
only without specifying photos.
Note: As a general rule, this unit will support up to level 1 of P.I.F. Rev.3.1
Note, however, any file that is saved in the following directories or their sub-directories
cannot be included as files to be printed.

Horizontal: 80 ≤ X ≤ 9200 (pixels)
Vertical: 80 ≤ Y ≤ 9200 (pixels)
PRODUCT DESCRIPTION Memory Card Print 20
EPSON Stylus Photo R240/R245/R250/ME PHOTO 20 Revision C
1.4.1.5 Maximum number of photo data files
This unit can handle up to 999 photo data files. If the amount of photo data to be
recorded exceeds the capacity of one memory card, this unit uses file sorting rules to
sort the photo data into valid photo data in frames numbered from 1 to 999. Although it
is possible to print photo data files with frame numbers over 999 that have been
specified for printing by camera specification files, the maximum number of frames
that can be specified is 999 frames.
If you insert a memory card that contains over 999 photo data files, only files up to 999
will be printed by the “Print All” or “Print index sheet” functions.
1.4.1.6 Thumbnail image data
This unit handles thumbnail image data in the DCF Version 1.0 or 2.0 format (Exif
format, 160 x 120 pixels).
During this unit’s Index sheet and memory card printing modes, the layout is 80
thumbnails per sheet (when using plain paper or special paper in high-speed print
mode).
1.4.1.7 File sorting
This unit stores all photo data files in the memory, using the photo data files’ full-path
file names (for example, “¥DCIM¥100EPSON¥EPSN0000.JPG”), and assigned photo
frame numbers. Since photo frame numbers are assigned based on this unit’s own
proprietary file sorting rules, the assigned frame numbers do not necessarily match
those indicated by digital cameras.
1.4.1.9 Rules for acquisition of date/time data
The following priorities are used to fetch date and time information from photo data
files.
1. Date/time data that complies with the standard format (Exif) for digital
cameras
2. Date/time data that complies with the DOS standard file system (file time
stamps)
3. Fixed values (01/01/1980, 00:00:00)
Note that the date/time data assigned to individual photo data files does not necessarily
match the date/time when the photo was actually taken. The photo date/time may be
modified due to the digital camera’s calendar settings (presence/absence of functions,
incorrect date/time settings, etc.), processing of the photo data after the photo was
taken, or subsequent saving of data. In such cases, this unit performs the relevant
processing based on the most recently modified date/time data.
1.4.1.10 Number of sheets which can be printed in total
Printing sum total number of sheets presupposes that it is possible to 999 sheets.
Moreover, the printing sum total number of sheets per sheet is possible to 99 sheets.
1.4.1.8 File sorting rules
This unit sorts photo data files based on the following prioritization rule.
File name is sorted in ASCII order as full path name.
Note: Sorting results are not guaranteed if two files have matching full-
path file names. (Matching full-path file names are not allowed
under the DOS specification.)

1.4.4 Trimming Function
A trimming function is provided as a means of coordinating photo data with the types
of photo frames handled by this unit. This function is always activated so that printing
photo data is in shapes that fit these photo frames.
This function is described briefly below.
The printed photo frame and the photo to be printed are matched in length along one
side and the photo is resized along the perpendicular side to fit the frame on that side.
Any part of the photo that does not fit within the photo frame is trimmed away (not
printed).
The image below shows an example in which the photo data is aligned vertically
with the photo frame.
These parts are
trimmed.

1.4.5 Assignment Rules for Photo Frame Numbers and Rotation
Top edge
The rules concerning photo frame numbers that are referenced when assigning photos
are described below. The numbers shown in each diagram and photo frame below
indicate the photo frame numbers used for various types of layout.
The direction of the number shown in each photo frame matches the direction of the
printed photo to which the horizontal photo data was allocated. When there are more
pixels vertically than horizontally, the vertical photo data is allocated instead, and the
number shown in the figure below is then rotated 90° before being printed. In Index
printing mode, the numbers are printed as they are shown below, regardless of the
shape of the photo data.
However, when the photo data has an equal number of pixels vertically and
horizontally the photos are printed without rotation, regardless of the layout.
NOTE: The vertical photo data refers to when the photo data file itself is set for a
vertical (portrait) orientation. Photo data is defined as the vertical photo
data if it is taken by a digital camera with a portrait position detecting
function.)

The basic operating principles of the Print Head, 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 uniform the ejected ink amount, the Print Head has its
own Head ID (13-digits code for this Print Head for Stylus Photo R240/R245/R250)
which adjusts PZT voltage drive features.
So, you are required to store the Head ID pasted on the Print Head into the EEPROM
by using the Adjustment Program when replacing the Print Head, the Main Board Unit,
the Printer Mechanism with new one. (Note: there are no resistor arrays to determine
the Head ID on the Main Board.) And then, based on the stored Head ID into the
EEPROM, the Main Board generates appropriate PZT drive voltage.
Following explains the basic components for the Print Head.
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
Print Head pushes the top of the ink cavity, which has ink stored, to eject the ink
from each nozzle on the nozzle plate.
Electric poles for CSIC
This Electric Poles connects the CSIC chip mounted on the Ink Cartridge. By
using this poles, current ink consumption amount data is red out from the CSIC
chip. And, the latest ink consumption amount data is written into the CSIC chip.
Nozzle Plate
The plate with nozzle holes on the Print Head surface is called Nozzle Plate.
Filter
When the Ink Cartridge is installed, if any dirt or dust around the cartridge needle
is absorbed into the Print Head, there is a great possibility of causing nozzle clog
and disturbance of ink flow, and alignment failure and dot missing finally. To
prevent this problem, a filter is set under the cartridge needle.
The Print Head has the Electric Poles (CSIC Connectors) to store the ink consumption
amount data into the CSIC chip mounted on the Ink Cartridge. By storing the ink
consumption amount data, this printer can detect the ink consumption status, such as
Ink Low/Out condition.
OPERATING PRINCIPLES Printer Mechanism 41
EPSON Stylus Photo R240/R245/R250/ME PHOTO 20 Revision C
Ink Cavity
The ink absorbed from the Ink Cartridge goes through the filter and then is stored
temporarily in this tank called “ink cavity” until PZT is driven.

2.2.2.1 Printing Process
This section explains the process which the Print Head of On-Demand inkjet printers
eject ink from each nozzle.
1. Normal state
When the printing signal is not output from the Main Board (C606 Main), or the
PZT drive voltage is not applied, the PZT does not change the shape. Therefore,
the PZT does not push the ink cavity. The ink pressure inside the ink cavity is kept
normal. (refer to Figure 2-4 (p.42): Normal state)
2. Ejecting state
When the print signal is output from Main Board (C606 Main), the nozzle selector
IC located on the Print Head latches the data once by 1-byte unit. Based on the
drive waveform (common 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 2-4 (p.42):
Ejecting state)

2.2.2.2 Printing Method
The dot printing systems of Stylus Photo R240/R245/R250 are variable dot printing
systems.
Variable dot printing
This printing mode is developed to improve the print quality on exclusive paper.
This mode is basically the same as variable dot printing mode used on other
products; micro dot, middle dot and large dot compose this mode. The printing dot
size varies according to the print data and this mode enables to output even sharper
image on exclusive paper.
Economy dot printing
Economy dot printing is basically used only during Economy mode printing. The
reason is that the resolution is low during Economy mode printing, so that the dot
size needs to be bigger.

2.2.3 Carriage Mechanism
The Carriage Mechanism consists of Carriage Unit (including the Print Head, CR
Encoder Board and PW Sensor), CR Motor, Timing Belt and CR Scale etc.
Following figure shows you each component for the CR Mechanism.
2.2.3.1 Carriage Mechanism
The following DC motor controls the CR Mechanism on this printer.
Table 2-1. CR Motor Specification
Items Specifications
Type DC motor with brushes
Drive Voltage 42V (DC) ± 5% (voltage applied to driver)
Armature resistance 29.1 Ω ± 10% (per phase at 25 degrees)
Inductance 20.1mH ± 25% (1KH 1Vrms)
Drive Method PWM, constant-current chopping
Driver IC A6627
Close loop control based on the CR Motor (DC Motor) and CR Encoder has
advantages in stabilized print quality.
Heat generation control
Using low-cost DC motors, this product grasps the variations of the torque
constants, coil resistances and power supply voltages of the individual DC motors
adequately to carry out heat generation control according to individual differences.
CR measurement sequence
To set the appropriate drive current value according to the variation of the CR
mechanical load, the mechanical load is measured in a CR measurement sequence
and saved into the EEPROM in a power-on or I/C change sequence. A fatal error
will occur if too much 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.

2.2.3.2 Carriage Home Position Detection
Like other conventional models, the carriage home position is detected using the CR
Motor drive current and the CR Encoder speed/position signals. Fundamental home
position detection sequence is described below.
1. Current position temporary detection sequence determines if the carriage is in the
carriage lock position and releases the carriage if it is locked.
2. The carriage is moved to the left frame hit position and the carriage motor is
stopped.
3. The position that is specified steps right from the stopping place is defined as an
origin, and from that time, positional information is monitored by the linear
encoder.
If the positional information could not be gained during detecting carriage home
position due to the following causes, fatal error occurs.
Obstructions on the carriage path or other factors are giving too much pressure on
the CR motor.
CR Encoder failure, CR Scale defect, etc.
2.2.3.3 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 on the right end plane
(area without the absorber) of the Front Paper Guide every time power is switched 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.
Paper Left/Right Edge Detection Control
Before start of printing (immediately after the end of paper locating), or during
printing, whether paper is present or not is detected to prevent off-paper printing
on the Paper Guide by borderless printing used in a wrong way.
Paper Top Edge Detection Control
Detects paper leading edge at start of printing. Also sets the amount of extension
for the paper leading edge during borderless printing.
Paper Bottom Edge Detection Control
Sets the amount of extension for the paper trailing edge during printing.

plays a role in loading a paper from the ASF Unit to the PF Roller. And also, the Paper
feeding mechanism plays a role in feeding a paper loaded from the ASF Unit. The
functions of the Paper loading/feeding mechanism varies depending on the rotational
direction of the PF Motor as the table below.

For your reference, the top or the end of a paper is usually detected with the PE Sensor.
In case that the PE Sensor cannot detect the top of a paper in the paper loading
sequence, the printer indicates the “Paper Out error”. If the PE Sensor cannot detect the
end of a paper in the paper feeding sequence, the printer indicates the “Paper Jam
error”. As for the details, refer to Chapter 3 “Troubleshooting” (p.58).
2.2.4.1 Paper Loading Mechanism
The Paper loading mechanism consists of the Change Lever in the Pump Unit, the
Holder Shaft Unit (including the Clutch mechanism) and the ASF Unit.
The Change Lever and the Clutch mechanism play a major role in the Paper loading
mechanism as follows.
1. ASF home position detection function
The ASF Unit on this printer does not have the ASF Home Position Sensor.
Instead of the ASF Home Position Sensor, the Change Lever and the Clutch
mechanism is used to detect the ASF home position.
When the Change Lever is set on the Clutch mechanism with the counterclockwise
rotation of the PF Motor pinion gear, the ASF home position is detected by this
lever for the paper loading operation. In this time, the printer cannot load a paper
from ASF Unit because the drive of the PF Motor is not transmitted to the LD
Roller Shaft.
2. Paper loading function
When the Change Lever is released from the Clutch mechanism with the
clockwise rotation of the PF Motor pinion gear, the ASF home position detection
function is changed over to the paper loading function. Therefore, the printer can
load a paper from ASF Unit because the drive of the PF Motor is transmitted to LD
Roller Shaft.
During paper loading, paper is transported from the ASF Unit into the printer by the
rotation of the 2 cams of the LD Roller.
Cam (Large): Hopper release
Cam (Small): Paper Back Lever release
When 1 page paper is loaded, the cams mentioned above prepare the Hopper and Paper
Back Lever for the next paper loading operation, and the remaining paper is returned to
the standby position.
Figure 2-7 (p.47) and Figure 2-8 (p.48) show you the ASF paper loading sequence and
the operation of each mechanism.

When the PF Motor
pinion gear rotates CCW
direction (right side

pushes down the Clutch
lever as right figure and
the Clutch lock tooth is
disengaged from the
Clutch Gear. As the
result, the LD Roller
Shaft dose not rotate at
all because the drive of
the PF Motor is not
transmitted. In this time,
the Hopper is also
pushed down by the two
cams on the LD Roller
Shaft, and the Paper
Back Lever is set to
avoid that papers are
slipped down from the
paper set position.
This position is the ASF

2.2.5.1 Capping Mechanism
The Capping mechanism covers the Print Head with the Cap to prevent the nozzle from
increasing viscosity when the printer is in stand-by state or when the printer is off.
When the Carriage Unit is in the
home position, the hook of the Slider
Lock Lever is not latched to the dent
of the Cap Frame.
In this time, the protrusion of the Cap

2.2.5.2 Pump Unit Mechanism
The PF Motor also controls the Pump Unit mechanism (including the Change Lever) as
well as the Paper loading/feeding mechanism. The drive of the PF Motor is always
transmitted to the Pump Unit. (And also, its drive is transmitted to the LD Roller
through the Clutch mechanism & the Change Lever.)
On this printer, the Pump Unit mechanism including the Change Lever plays a major
role expecting the ink eject operation. And, these operations control depending on the
PF Motor rotational direction as the following table below.

2. Carriage lock operation by the Change Lever
This printer does not have the Carriage Lock Lever with the Wiper.
Instead of the Carriage Lock Lever, the Change Lever is set to the right side of the
printer while the Carriage Unit is in the CR home position.
(As for the detailed mechanism for setting the Change Lever, refer to Figure 2-7
(p.47) Step 2)
2.2.6 Ink Sequence
Initial Ink Charge
After the printer is purchased and the power is turned on for the first time, the
printer must perform the Initial Ink Charge to charge the ink inside the ink cavity.
When the Initial Ink Charge is completed properly, the printer releases the flag
inside the EEPROM. The Stylus Photo R240/R245/R250 takes about 114 seconds
to complete the initial ink charge sequence. If the power is turned off during the
Initial Ink Charge, the CL3 will be performed at next power on timing.
Manual Cleaning
The Stylus Photo R240/R245/R250 has three types of manual cleaning to remove
blockages in the nozzles caused by the thick ink and to remove any other foreign
substances. All the three types of cleaning consume ink. CL3 consumes the largest
of ink, then CL2, and CL1 uses the least ink among them.
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 has not
reached a preset value. Only when the cumulative printing timer counter is more
than has not reached a preset value, execute only CL1.
Additionally, if the I/C is Ink Low or Out condition, any manual cleaning is
prohibited and it is displayed on the LED indicators.
Timer Cleaning
The RTC mounted on the Main Board works as a timer. It counts time interval
from when the printer is powered off to the next power-on. According to the
counted time interval, the printer, automatically performs the Timer Cleaning.
Flashing
Two different flushing operations are executed for the following reasons.
Pre-printing flushing
This is done before a start of printing to eliminate ink viscosity in the Print
Head nozzles.
Periodic flushing
This is done during printing to prevent ink viscosity in the Print Head nozzles
from increasing.

Combination circuit (RTC circuit, Reset circuit, EEPROM circuit)
The printer mechanism is controlled by the above circuits. Following explains the
major characteristics of this Main Board.
Adoption of 3.3V/1.5V drive logic circuit components
The 5V formed by the Combination Motor Driver (IC5) of C606 Main Board is
stepped down to 3.3V by the Regulator (IC6), and it is then used as drive voltage
for many elements. In addition, when the printer shifts to low power mode, the
3.3V that was stepped down by the Regulator (IC6) is stepped down to 1.5V by the
Combination Motor Driver (IC5) and elements that had been driven by 3.3V are
driven by 1.5V for suppression of power consumption.

4.1.1 Precautions
The precautions in the two lists below (WARNING and CAUTION) must always be
followed during disassembly and assembly.
W A R N I N G
Disconnect the power cable before disassembling or assembling
the printer.
If you need to work on the printer with power applied, strictly
follow the instructions in this manual.
Always wear goggles to protect your eyes from splattering of
ink. If ink gets in your eye, flush the eye with fresh water and
see a doctor immediately.
Always wear gloves for disassembly and reassembly to avoid
injury from sharp metal edges.
Use static discharge equipment such as anti-static wrist straps
when accessing internal components to protect sensitive
electronic components and circuitry.
Never touch the ink or wasted ink with bare hands. If ink comes
into contact with your skin, wash it off with soap and water
immediately. If irritation occurs, contact a physician.
C A U T I O N
When transporting the printer on which the ink cartridges
have been installed, secure the cartridges with pieces of tape to
the printer cover so that they do not move from the home
position.
Use only recommended tools for disassembly, assembly or
adjustment of the printer.
When tightening screws, be sure to observe the specified
tightening torque.
Use only specified grease.
(See Chapter 6 “MAINTENANCE” (p140)for details.)
Make the specified adjustments when you disassemble the
printer. (See Chapter 5 “ADJUSTMENT” (p136) for details.)
Make sure the tip of the waste ink tube is located at correct
position when reassembling the waste ink tube, or it will cause
ink leakage.

4.2 Cautions on Disassembly/Reassembly of
Printer Mechanism & How to Ensure Quality
of Reassembled Printers
Removing the Lower Housing from the Printer Mechanism has been basically
prohibited for the conventional low-end printers. Because the Main Frame of those
printers is not so strong that it may be deformed due to the force exerted on it during
removing parts such as Ink System from the Printer Mechanism without removing the
Lower Housing.
Whenever replacing any parts which require the Printer Mechanism to be removed, we
have recommended to replace the Printer Mechanism together with the Lower
Housing.
To replace the Waste Ink Pad, however, the Lower Housing must be separated from the
Printer Mechanism.
This section describes cautions on reassembling the Printer Mechanism separated from
the Lower Housing to ensure quality of reassembled printers.
[Cautions on Disassembly/Reassembly of Printer Mechanism]
1. Main Frame
(a) Printer Mechanism Positioning Requirements
[Purpose]
• The correct installation positions of the parts comprising the Printer
Mechanism are ensured by carefully checking the specified points in
relation to the Lower Housing.
[Positioning Requirements]
• To ensure the installation accuracy, the position of the Printer Mechanism
must be checked in X, Y, and Z directions as described below.
[X direction]
• The Main Frame of the Printer Mechanism should be correctly set into the
groove of the Lower Housing.
• There should be no gap between the Main Frame and the Lower Housing.
[Y direction]
• The Main Frame of the Printer Mechanism should be correctly set into the
groove of the Lower Housing.
• There should be no gap between the Main Frame and the Lower Housing.
[Z direction]
• The positioning holes of the Main Frame should be set into the guide pins of
the Lower Housing so that the frame and housing are in close contact with
each other.
(b) Cautions on Reassembling the ASF Unit and Upper Paper Guide Unit
[Purpose]
• To prevent deformation of the Printer Mechanism (Main Frame) due to an
excess force exerted on it during reinstalling the above three units. Any
deformation of the Printer Mechanism (Main Frame) will adversely affect
the printing result or can cause the printer to malfunction.
[Handling Requirement]
• When attaching any of the three units, be sure to support the Main Frame or
components behind the unit with your hand so that the force to attach the
unit is not exerted on the frame from only one direction.
2. Carriage Unit
(a) Cautions on Handling the Carriage Unit
[Purpose]
• To avoid damaging the Carriage Unit during disassembly/reassembly work.
Any damage of the Carriage Unit can cause fatal errors during the printer is
used by the user.
[Handling Requirement]
• Be extremely careful in handling the Carriage Unit not to damage it during
disassembly/reassembly work.
[Ensuring Quality of Reassembled Printers]
Make some test prints using the Adjustment Program. The quality of the reassembled
printer is ensured if the test print results are satisfactory.
