Digital Pen and Dot Screen Troubleshooting
There is no response to digital pen operations on the dot screen or printed documents with
special dot patterns with the digital pen.
Probable Cause
The digital pen battery is dead.
The digital pen is turned off.
You are blocking the camera lens
in the nib of the digital pen with
your finger, etc.
DSPD is not running or it was
installed incorrectly.
The digital pen is not paired with
your computer.
The Bluetooth adapter was moved
to a different USB port.
Troubleshooting
Replace the battery.
Inadvertently depressing the switch
on the pen that detects whether the
cap is in place (and turns it off when
it is) with your finger will cause the
digital pen to turn off. Release the
switch (so it is not depressed),
which will turn on the digital pen
and restore normal operation.
Digital pen power will turn off automatically if it is left with its cap removed
for about seven and a half minutes without performing any pen operation. If
this is the cause, replace the cap and then remove it again.
The digital pen has a built-in camera that reads what is under the pen. Proper
pen operation will not be possible if the camera lens becomes blocked by your
finger or something else. Check to make sure that the camera lens is not being
blocked by something.
Digital pen operation requires the DSPD digital pen driver (page 17). Check the
points below.
Is the DSPD icon (
) displayed in your computer's task tray?
If it isn't, restart your computer. If the icon does not appear after your
computer restarts, reinstall DSPD.
Is the DSPD icon (
) in your computer's task tray red?
This means that your DSPD has generated an error. Re-install DSPD.
For information about how to re-install, see "Re-installing the Software"
(page 87).
Digital pens need to be paired individually, one by one. Refer to "Establishing
a Connection between the Digital Pen and Computer (Pairing)" (page 12) and
pair the digital pen with your computer.
As a general rule, the Bluetooth adapter must stay connected to the USB port
where it was originally connected on a computer. Moving the Bluetooth
adapter to a different USB port will cause it to be recognized by the computer
as a new USB device, and you will have to re-install the driver and reconfigure
all of the required settings. If you do move the Bluetooth adapter to another
USB port, you will need to pair all of your digital pens with the computer.
