63
Causes
Something is blocking
the cameras.
Something is on the
reflective tape channel.
Your finger or pen is
skipping as you draw.
This is most common on
the upstroke.
Bright lights are
interfering with the
cameras.
Your cameras require
calibration, possibly due
to temperature change
in the room.
You're in Locked Ink
mode and all objects are
interpreted as pens.
You're using an edge of
the eraser.
Your interactive flat
panel is interpreting an
eraser.
Solution
Ensure that nothing is taped to the
screen.
Remove items from the reflective tape
channel.
Use consistent pressure whilst drawing
digital ink.
Close blinds or shades or dim all
halogen lights and LEDs.
Calibrate your interactive flat panel.
(See page 50.)
Press a colour select button that isn't
flashing to exit Locked Ink mode.
OR
Remove the eraser from the eraser
holder to enable erasing while in Locked
Ink mode.
Increase the contact area of your
eraser.
Lift other fingers and the heel of your
hand from the interactive flat panel
whilst you write because the interactive
flat panel is interpreting them as an
eraser.
OR
Use a smaller pointer, such as the pen.
