When the card slot is mounted, the following icon appears on Computer (or My Computer).
Restrictions on Card Slot Use over a Network
• The card slot can be shared by multiple computers, if the machine is connected to a network.
Multiple computers can read files from a memory card in the card slot at the same time.
However, while one computer is writing a file into a memory card, other computers cannot
access the same file.
• If your computer joins a domain, the card slot may not be mounted as the network drive.
• If you use the memory card stored the large size files or many files, a large amount of card
access may be generated. In this case, the operation in the memory card may be impossible or
slow. Operate after the Access lamp of the machine is lit.
• When you access the network drive for the card slot over the network, file names consisting of
eight or less lowercase letters (not including its extension) may be shown in uppercase.
For example, a file name such as "abcdefg.doc" will be "ABCDEFG.DOC", while a name such as
"AbcdeFG.doc" will appear the same.
The file is not actually renamed, but merely appears to be changed.
• When you enable a memory card in the card slot of the machine to be writable only from a USB-
connected computer, you cannot access the network drive of the card slot. On the other hand,
when you enable it to be writable only from a LAN-connected computer, the card slot is not
detected via USB. Make sure that the card slot setting is selected properly according to your
connection method.
To read files from a memory card via USB and over a network, disable the function to write files
to a memory card from a computer. You cannot write files to a memory card in either way with
this setting.
• When you enable a memory card in the card slot of the machine to be writable only from a LAN-
connected computer, you can write files to a memory card from a computer connected to a
network. Note that it may increase the risk that the data on the memory card is infected by
computer viruses or accessed illegally.
It is recommended to use the access control function of the machine or connect to the Internet
via a router. For information on using a router, contact your Internet service provider or a network
device manufacturer.
• If you write files to a memory card over a network when IJ Network Scanner Selector EX is not
running, the Date Modified of the files may not be proper. Make sure to start up IJ Network
Scanner Selector EX before you write files to a memory card over the network. Refer to "IJ
Network Scanner Selector EX Menu and Setting Screen" for your model from the Home of the
Online Manual for details.
