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.

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.

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.

Table 1-9. Movie Print

Printing Options Function

1 frame printing

Each medium can be rewritten only a limited number of times as described below.

• 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-formatted MO is impossible.

• MOs formatted in an unreadable format such as Macintosh HFS or Windows NTFS are reformatted.

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

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

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

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.

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 unsupported character code is already exists in the medium, the change is cancelled and the file or folder cannot 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 name 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 replaced with 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.

Moves along the CR shaft to print on paper being powered by the CR motor.

The unit includes Printhead, PW sensor, and CR encoder sensor.

Moves the carriage upward/downward to adjust the platen gap being powered by the PF motor. There are 4 preset levels of platen gap and the unit moves the carriage to one of the levels according to the current carriage position detected by the APG sensor.

Being powered by the PF motor, feeds paper loaded on the ASF into the printer mechanism.

Being powered by the PF motor, ejects paper or the CDR tray.

The EJ frame moves upward/downward corresponding to the stacker that can be moved manually so that the frame matches with the paper size.

Located on the right side of the printer mechanism. Covers the printhead with the cap holder when the printhead is not used, and draws waste ink out of the printhead. The waste ink is sent to the Waste Ink Tray through the waste ink tube.

Summary

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.

 Adjustment/Correction method

Correction values of the BRS and the PFP are automatically calculated when a pattern printed by the printer is scanned by a specified scanner. The created correction values are stored into the serial flash ROM on the main board, and applied when printing in the target print mode.
