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 mediu m in an enable d slot is rem oved, the next pri ority slot be comes ena bled if a med ium is in th e slot . Reinser ting the me dium in the n ext priori ty slot is n ot required. If no media is detected, the CF slot becomes enabled. Removing/reinserting media in disabled slot s 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. Th e total number of image files does not change if ano ther medium is inserted into a disabled slot.

When accessing media from a Windows PC: One remova l 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.

C H E C K

P O I N T

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

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

Page 14

EPSON Stylus Photo R260/R265/R270, R360/R380/R390 Revision A

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.

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. B ecause 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.

File Sort Rule

The printer sorts photo data files by their full pathnames in ASCII order.

NOTE: The sorting may fail or be completed improperly if multiple same full pathnames

exist. (the existence is not allowed under normal MS- DOS environment.)

Date Data Acquisition

The printer acquires the date and time data of each photo data file according to the priority list given below.

1. From a digital camera. Acquires date and time data conforms to digital camera standard format (Exif).

2. From a PC or other external device. Acquires date and time data (timestamp of the file) assigned by the file system compatible with MS-DOS.

3. Fixed date and time (1 January 1980 00:00:00)

Note that the acquired date and time of each photo data file is not necessarily the exact date of shooting the photo. The date and time data can be updated after shooting by digital camera’s calendar setting, post-processing or restoring of the photo data. If the data has been updated, the printer acquires the updated date and time information.

Date Range

The printer can handle the following range of date. If photo data files have date and time information outside the range, the printer cannot sort files correctly.

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.

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.

(R360/R380/R390 only)

Stylus Photo R360/R380/R390 allows the user to easily make a backup of his/her memory card without using a computer. Furthermore, photos in a backup copy can be printed directly from the printer.

Function summary

 Backup entire data in a medium (CF, Smart Media, Memory Stick, SD, xD-

Picture Card).

 Creates a backup folder automatically in the destination medium each time a

backup is carried out

 Displays a warning message when data size to be backed up exceeds the

destination medium capacity.

 Direct print of the backed up data is available.  Formats the destination medium when the medium has not been formatted or

formatted in an unreadable format. (this does not work for CD-R/DVD-R drives)

P O I N T

Each medium can be rewritten only a limited number of times as describe d be l ow .

• 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.

• DVD-R 4.7GB max. 274 times

The number of writings is limited as shown above because each session information must be saved.

• DOS/Windows-formatted MO is recommended.

• Reformatting a pre-for matted MO is imposs ible.

• MOs formatted in an unreadable format such a s Macintosh HFS or Windows NTFS ar e reformatted.

• CD-RW media cannot be used due to the difference of record ing method.

• Backup to a CD-R once burned using a device other than the printer is not guaranteed.

• DVD+R, DVD±RW, DVD-RAM media cannot be used due to the difference of recording method.

• Back up to a DVD-R once burned using a device other than the printer is not guaranteed.

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 na me: EPSONXXX.JPG  Folder name: EPDIRXXX

NOTE1 :

001-999 numbers are appli ed to XX X in asc en din g ord er .

An unsupported character-code used in the extension is replaced with an underbar.

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.

If a file or folder name that is automatically changed due to an unsupport ed character code is already e xists in the medium , the chang e is cance lled and th e file or fol der cann ot be backed up.

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 na m e length: Max. 255 bytes  Path length: Max. 1023 bytes

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.

NOTE: Characters available for a folder and file name are capital alphanumeric and

underbars. Characters other than those are repla c ed w ith underbars.

C H E C K

P O I N 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.

2.3 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 Redu c tio n System (BRS) and Paper Feed Profile (PFP) Correction system. The

overview of them is described in the table below.

Summary

Conventional models perform overlapping printing (2-path or 4path print) to reduce banding pro blem. Printers th at incorpo rate the Banding Reduc ing System d o not perf orm the ov erlapping p rinting. 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 hig h print speed.

In the conventional method to im prove paper feed accuracy, the adjustment value is calculated based on a value obtained at a certain point of paper. Therefore, correct ing the total paper feed amount (from when paper is fed and to when fi nishing 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 calculat ed for each of the points. This enables to ensure print qualit y in th e target print mode.

4.1 Overview

This section describes p rocedures 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 requ ir ed aft er r eass e mbly of components or par ts 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 disas s embly and assembly.

4.1.1 Precautions
