Troubleshooting
Connection to the computer
Symptom Cause/Remedy
The Reader cannot
be recognized by
your computer.
 The USB cable is not connected
properly. Reconnect it.
 A USB hub or USB extension cable
is used for the connection.
Connection via an extension cable
or USB hub is not guaranteed.
Connect the USB cable directly to
the computer.
 Verify that (indicating
connection via USB) is displayed at
the top of the Reader’s screen. If
the Reader still cannot be
recognized, disconnect the USB
cable from the Reader, then
reconnect it after a while.
 If “Device Lock” of the Reader is set
to “On,” set it to “Off.” If the Reader
is locked, it will not be recognized
by your computer.
 While the Reader is connected to a
computer, do not turn on, restart,
wake up from sleep mode, or shut
down the computer. These
operations may render the Reader
unrecognizable by the computer.
Disconnect the Reader from the
computer before performing these
operations.
