Note : Only one medium is accessible at a time either from the printer or a PC. When multiple media are detected at power-on, the printer accesses one by one in the predetermined order given in the priority column. When a medium in an enabled slot is removed, the next priority slot becomes enabled if a medium is in the slot. Reinserting the medium in the next priority slot is not required. If no media is detected, the CF slot becomes enabled. Removing/reinserting media in disabled slots does not affect the access priority. When a target medium does not become accessible because of another medium inserted in a slot that has higher priority than the target one, remove the another medium in order to enable the target slot. Notes on handling memory card by access method When accessing media from the printer: Frame numbers are automatically assigned to image files in an accessible medium. The total number of image files does not change if another medium is inserted into a disabled slot. When accessing media from a Windows PC: One removal disk drive is displayed even when multiple media are inserted into the printer slots. A medium in an enabled slot is accessed from the removal disk drive. When accessing media from a Macintosh PC: A medium in an enabled slot is mounted on the desktop. Another medium inserted in a disabled slot is not mounted.

DCF Version1.0 or 2.0 compliant format. DOS FAT format (FAT12/FAT16/FAT32*1) with single partition (basic partition) CD-R media: ISO9660(Joliet) format DVD media: ISO9660(Joliet) or ISO9660(Joliet)&UDF bridge format*2
NOTE *1 : FAT32 is permitted for media allowed to be used by corresponding memory card standards. *2 : UDF-formatted DVDs are not supported.
Files saved in the directory (or its sub directory) listed below are not supported for printing.
Hidden or System folder RECYCLED folder PREVIEW folder (stores thumbnails in CASIO DSCs) SCENE: folder (stores data for best-shot function in CASIO DSCs) MSSONY: folder (stores e-mail images, voices, movies, or uncompressed images in SONY DSCs) DCIMALBUMIMAGE: folder (stores data for album function in CASIO DSCs)
File Type
File types available for the standalone print are as follows: JPEG file (*.JPG) A photo data file that conforms to Exif Version 2.21 (Exif version 1.0/2.0/2.1/2.2/2.21 are supported) TIFF file (*.TIF) An uncompressed RGB photo data file that conforms to Exif Version 2.21 (Exif ver. 1.0/2.0/2.1/2.2/2.21 are supported) Camera specification file (*.MRK) A definition file required when printing using settings made on a camera. AUTPRINT.MRK file that has a full pathname of up to 32 characters is valid.
Valid Image Sizes

Available image sizes for stand-alone print are as follows: Horizontal: 80 X 9200 (pixel) Vertical: 80 Y 9200 (pixel)
Maximum Number of Photo Data Files

The printer can handle up to 999 photo data files in a single memory card. If the number of files stored in a card exceeds the limit, first detected 999 files become valid and others are ignored displaying the total number of files as 999. (1 to 999th photo files are printed when Print All or index print is selected.) Since the file detecting order changes depending on how the files are stored (folder hierarchy or other factors), it is

not guaranteed which files are selected when the number of files is 1000 or more. When photo data files to which a camera has assigned numbers over 999 are specified to be printed, they can be printed unless the total number of files exceeds 999.
Revision A Image files associated with P.I.F.3 script

When an image file associated with P.I.F.3 script file include a rotation tag, the image is rotated as specified by the tag every time it is printed. If the image is printed with a prestored or imported P.I.F. frame that has not associated with any images, rotation direction of the image may differ from that of an image which has not associated with P.I.F.3 script.
File Sort
The printer sorts all the photo data files in a memory card using their full pathnames (such as \DCIM\100EPSON\EPSN0000.JPG) and assigns numbers to them. Because the number assignment rule is specific to the printer, the numbers assigned by the printer do not necessarily match the numbers assigned by a camera.
1.3.2 Direct Print of Movie Frames

The user can view a movie in a memory card on the printer LCD and select a desired frame of the movie and print the frame. The following two options (1 frame/12 frames) are provided. Table 1-9. Movie Print
Printing Options Function When Movie Enhance setting is ON, selected one frame and the next two frames are printed. When Movie Enhance setting is OFF, the selected one frame is printed. The user is required to select a start frame and an end frame. The printer divides the selected portion of a movie into 12 frames to be printed. Movie Enhance setting cannot be made. 1 frame printing

MO: max. 512 times (001 to 512) If any files other than backup folders exist in the route directly, the max. number of writings becomes less than 512 due to the MS-DOS restriction. When more than 512 times of writing history of an inserted MO is detected, the printer handles it as a backup error (file name error, folder hierarchy error). CD-R 640MB max. 47 times 700MB max. 50 times The number of writings is limited as shown above because each session information must be saved.

EPSON Stylus Photo R260/R265/R270, R360/R380/R390 Writing Format for CD-R Media
Writing to CD-R media is made in multisession type (Model 1) and ISO-9660 (Joliet)compliant format. Files or folders whose name includes an unsupported character code or is too long (file/ folder name must be less than 8 characters, and the extensions must be less than 3 characters), the names are automatically changed as explained below. File name: EPSONXXX.JPG Folder name: EPDIRXXX
NOTE 1 : 001-999 numbers are applied to XXX in ascending order. 2 : An unsupported character-code used in the extension is replaced with an underbar. 3 : During a single backup operation, the number of automatic change of file/folder names is limited to 999 times. When it exceeds, no more files/folders that contain an unsupported character-code cannot be backed up. 4 : If a file or folder name that is automatically changed due to an unsupported character code is already exists in the medium, the change is cancelled and the file or folder cannot be backed up.
Revision A Backup Restrictions

Browsing an external device from a PC cannot be made. The printer and an external device must be directly connected with a USB cable. Connection via a HUB is not supported. A connection with a PC must have been disconnected before starting a backup in order to establish exclusive access over the medium to be backed up. There is no need to physically disconnect the PC (disconnect the USB cable). Partitioned media cannot be used for backup. Writing backup data stored in a medium back to a memory card or other media cannot be made because it may destroy the data in a DSC. Since the printer does not have calendar function, created date and time of backup files is the date and time initially assigned or updated by a device other than the printer.
Writing Format for DVD-R Media

Writing to DVD-R media is made in UDF 1.50 (ISO9660 Bridge) format. The file name length and the path length have the following limitations. File name length: Max. 255 bytes Path length: Max. 1023 bytes
NOTE: Characters available for a folder and file name are capital alphanumeric and underbars. Characters other than those are replaced with underbars.
C H E C K P O IN T
A memory card that has 8-level or more hierarchy of directories cannot be backed up to both a CD-R and DVD-R.
Operation After Backup to CD-R/DVD-R Media

The CD-R/DVD-R is automatically ejected from the external device.

2.2.1 Main Features

Features common to R260/R265/R270 and R360/R380/R390 The circuits support multi-common printing method that achieves high-speed printing reducing the number of carriage movements. Features of C658Main Board (R360/R380/R390) The CPU incorporates an ASIC for controlling memory cards. The ASIC achieves high-speed access to a card and offers USB2.0 host function. Employs SOC06H that incorporates one main processor and six image processing processors enabling concurrent processing for printing. 16-bit DDR1-SDRAM (166 MHz) memory for image processing on the local side enables a wide range of memory access. 72 MHz SDRAM is on the CPU bus as a system memory enabling a wide range of memory access. By employing a self-powered motor driver, the cost for supplying power to the RTC (5V) and USB HostVCC (6V), and for motor drive circuit are reduced. UBEC (Ultra Block Encode) allows MW buffer size to be reduced to one third the conventional size. Equips a 3.5inch Color TFT LCD as standard.

2.3 Banding Reduction System (BRS) / Paper Feed Amount Profile Correction (PFP)
Overview In order to ensure high print quality and high print speed, this product incorporates the Banding Reduction System (BRS) and Paper Feed Profile (PFP) Correction system. The overview of them is described in the table below. Table 2-6. Overview of BRS and PFP
Summary
Paper Type
Target Print Mode

Paper Size Resolutions (dpi)
Remarks
BRS
Conventional models perform overlapping printing (2-path or 4path print) to reduce banding problem. Printers that incorporate the Banding Reducing System do not perform the overlapping printing. They carry out 1-path printing correcting ink drop amount for each raster mode in order to avoid making a gap between each path (printed line). This enables to achieve both high print quality (less banding) and high print speed. In the conventional method to improve paper feed accuracy, the adjustment value is calculated based on a value obtained at a certain point of paper. Therefore, correcting the total paper feed amount (from when paper is fed and to when finishing printing) was impossible. The Paper Feed Amount Profile Correction offers more precise control over the paper feeding. Paper feed errors are measured at various points and a correction value is calculated for each of the points. This enables to ensure print quality in the target print mode.

DISASSEMBLY/ASSEMBLY
Revision A
4.1 Overview
This section describes procedures for disassembling the main components of the Stylus Photo R260/R265/R270 and R360/R380/R390 Unless otherwise specified, disassembled units or components can be reassembled by reversing the disassembly procedure. Procedures which, if not strictly observed, could result in personal injury are described under the heading WARNING. CAUTION signals a precaution which, if ignored, could result in damage to equipment. Important tips for procedures are described under the heading CHECK POINT. If the assembly procedure is different from the reversed disassembly procedure, the correct procedure is described under the heading REASSEMBLY. Any adjustments required after reassembly of components or parts are described under the heading ADJUSTMENT REQUIRED. When you have to remove any components or parts that are not described in this chapter, refer to the exploded diagrams in the appendix. The precautions in the two lists below (WARNING and CAUTION), must always be followed during disassembly and assembly.
W A R N IN 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. 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. 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. 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. Incorrect positioning of the tube may cause ink leakage. When transporting, do not remove the ink cartridges. Pack the printer with the cartridges installed. Use only recommended tools for disassembly, assembly or adjustment of the printer.(Table 4-1, List of Tools, on page 58) Be sure to tighten the screws to the specified torque. Apply lubricants and adhesives as specified. (See Chapter 6 Lubrication (p.129) for details.) Make the specified adjustments when you disassemble the printer.(Chapter 5 contains additional information on adjustments. 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. Be careful not to scratch or damage the coating on exterior surface of the product during disassembly and reassembly.

MAINTENANCE
Revision A
6.1 Overview
This section provides information to maintain the printer in its optimum condition.
6.1.2 Service Maintenance

If any abnormal print (dot missing, white line, etc.) has occurred or the printer indicates the Maintenance request error, take the following actions to clear the error. (This error is displayed in EPSON Status Monitor 3 and in the LCD Panel for R360/ R380/R390, and with LED for R260/R265/R270.)
6.1.1 Cleaning
This printer has no mechanical components which require regular cleaning except the Print Head. 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
6.1.2.1 Print Head cleaning

When dot missing or banding appears on images, run the Print Head cleaning cycle.* The cleaning be activated from the control panel, the printer driver utility or the Adjustment program.
Note * : This printer has three manual cleaning modes. The appropriate cleaning mode is automatically selected and performed according to various conditions. The ink consumption amount for manual cleaning varies depending on the mode.
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 Unit. Use 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.
6.1.2.2 Maintenance request error

Ink is consumed also for cleaning and flashing operations. When the ink is used for cleaning and flashing operations, the ink is drained to the Waste Ink Pads via the Pump. The amount of the waste ink is stored as the waste ink counter into the EEPROM. When the waste ink counter has reached the limit of the absorbing capability of the Waste Ink Pads, the maintenance request error is displayed. This printer takes the ink evaporation amount into consideration, therefore the counter limit differs depending on how often printing is made.
C H E C K P O IN T
Exterior parts Use a clean soft cloth moistened with water, and wipe off any dirt. If the exterior parts have ink stain, use a cloth moistened with neutral detergent to wipe it off. Inside the printer Use a vacuum cleaner to remove any paper dust. LD Roller When paper loading function does not operate because of a drop in friction force of the LD Roller due to paper dust, use a soft cloth moistened with alcohol to remove the paper dust.
For display of Maintenance request error, see the following. Chapter3 "Troubleshooting" (p.31)
When the maintenance request error appears, replace the Waste ink pads with a new one and reset the waste ink counter using the Adjustment program. If the waste ink counter is close to its limit, recommend that the Waste ink pads will be replaced with new one. This is because the Maintenance request error will may occur after returning the repaired product to the customer.
