The scanning time on the au-

scanning. If scanning does not
finish within the limited time, the
corresponding message ap-
pears.
For details on the scanning time,
contact your service representa-
tive.

thentication unit is limited to five

does not finish within five sec-
onds, the corresponding mes-
sage appears.
Remedy
Check that the cord is correctly
inserted into the connector.
Specify the desired position for
stapling. (p. 5-11)
Remove the paper from the pa-
per tray, turn it over, and then
load it again.
Slide the lateral guides in the pa-
per tray against the sides of the
paper so that there is no gap.
Configure the paper type of the
selected tray correctly.
Turn off the main power of this
machine, disconnect the USB
cable from this machine or au-
thentication unit, and then con-
nect it again. Wait at least 10
seconds, and then turn on the
main power of this machine.
Restart your computer.
Check that your computer is in-
stalled to the computer correctly.
(p. 10-3) (p. 11-3)
Set the notice sound to ON.
(p. 10-3)
To finish scanning within the lim-
ited time, confirm how to perform
authentication and how to place
your finger when scanning.
(p. 10-3)
During scanning, place the
scanned part on the scanning
section correctly, and do not
move it until results have been
obtained.
If the scanned part is dusty or
rough and dry when performing
authentication, a correct image
will not be able to be obtained,
and scanning may not finish.
Clean your finger, and then scan
it again, or improve the rough
and dry condition of your finger.
If the scanned part is too thick or
thin (when the finger width is out-
side the range from 10 to 25
mm), a correct image cannot be
obtained, and scanning may not
finish. Try "stretching your fin-
ger", "placing your finger deep-
ly", or "placing your finger
shallowly" on the scanning sec-
tion.
