P O I N T
made on an ISO9660 Level 1-formatted CD-R.

File name
Note *1: As a backup to CD/DVD media requires time, a folder hierarchy definition file
(EPBKINF.DAT) is first created under the backup folder.
*2: xxx stands for a 3-digit number. The number is automatically assigned from 001 in
each folder of directory.
The maximum number of writing times
C H E C K
P O I N T • FAT12/16-formatted media: up to 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, to folder hierarchy error).
• CD-R:
This is because each session information must be saved.
• DVD-R:
This is because each session information must be saved.
Other restrictions on the backup function
The printer does not have the function to write a backup data on an external
media back to a memory card in order to prevent the possible corruption of
data.
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.
Specification
A backup folder is automatically created on the destination media to save
the backup data keeping the original folder
A number (001 to 999) is assigned as the folder name.
The printer automatically formats the destination media in a supported
format if the media is rewritable and detected as unformatted or formatted
in unsupported format.
Because ISO9660 Level1 format is used to write backup data to a CD/
DVD, double-byte characters are not allowed to be used for the folder or
directory names. Any file or directory names that include double-byte
characters are automatically changed in accordance with the rule
described below.
• A file name is changed to "EPSONxxx"*
• A directory name is changed to "EPDIRxxx"*
• Replaces an unsupported character in the extension with "_" (underbar)
640MB: up to 47 times
700MB: up to 50 times
4.7GB: up to 274 times
