Product Description Specifications of Each Function 25
1.7.3 Backup Function
The Backup Memory Card function provided in the Setup mode allows the user to
make a backup copy of a memory card on a media in an external device. Printing the
backed up images directly from the external device also can be made.
1.7.3.1 Backup Function Specifications
Note *1: A backup on 700MB or larger size CD-R is not ensured.
*2: The CD-R/DVD-R must be formatted as described in Table 1-23 .
*3: The printer cannot recognize USB flash memory that incorporates a hub.
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.
† 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.

is restricted as described below;

A number (001 to 999) is assigned as the folder name.
Format
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.

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).

700MB: up to 50 times
This is because each session information must be saved.
