Problems
Solutions
1
When the device is
turned on, the LED
indicator is off.
Once the USB is connected to the computer, there
is no picture output. If the LED indicator is still off,
turn on the image via software, and the LED will
show blue indicator.
2
No screen with
Ladibug software
1. Change the USB cable
2. Please try the USB port on the back of the
computer or other USB port
3. Make sure no other application software has
DC-F20 images open at the same time. If other
software is already using DC-F20 images,
Ladibug software cannot output the screen
3
Unable to focus
Probably the document is too close. Press the pull
away the distance between the lens and the
document, and then press the upper Auto Tune
button to automatically adjust the focal length of
image.
4
DC-F20 cannot
operate normally
The machine cannot operate normally probably
because the power supply of the USB port at the
front end of the computer is insufficient. Try to
connect to a USB port at the rear end or a USB hub
with a power adapter.
5
Output screen flicker
The presetting value of Ladibug current frequency
is 60 Hz. If current frequency of your local country
is 50 Hz, output screen flicker may occur during the
use of Ladibug.
Please refer to the Camera Settings section of the
Software Manual to change the power frequency
setting to 50 Hz.
