GENERAL PROBLEMS
The computer does not
have an available USB port.
Check if there is an available USB port on a USB hub. If not
available, you will need to add a USB hub or USB card.
A USB device plugged into
one of the pen display’s
integrated USB ports does
not function.
1. Make sure the pen display itself is properly connected to a
working USB port on your computer.
2. Then be sure the pen display is powered on and that the power
LED lights blue. The DTF-521 contains a powered USB hub and
the integrated USB ports will not work when the power is off.
3. If the USB device does not work, try plugging it into a USB port
directly on your computer.
4. If your USB device is still not functioning properly, please contact
the manufacturer for that particular device.
The pen display power LED
is off.
Make sure the pen display power switch is turned on.
Check that the AC power adapter is plugged into both the pen display
and an active power outlet.
Use only the power adapter that came with the pen display; other
adapters may cause damage to your product.
The pen works only in
mouse mode, and does
not draw or write with
pressure sensitivity.
The tablet driver software was not installed or did not load properly.
Make sure the tablet driver software is installed and functioning.
Install the pen tablet driver software in accordance with the
instructions found in the Installation section of this guide.
The pen does not draw or
write with pressure
sensitivity.
Some applications require that you turn on the pressure capabilities
within the application or selected tool before the pen will respond as a
pressure-sensitive tool.
Verify also that your application supports pressure sensitivity.
Clicking is difficult. Open the Pen Tablet control panel and go to the Pen tab. Try using a
lighter T
IP FEEL.
The pen selects everything
or will not stop drawing.
Open the Pen Tablet control panel and go to the PEN tab. Move the
TIP FEEL slider toward FIRM. If this does not help, see Testing the
DTF-521 on page 32.
