Additional information 21
- The lens is blocked (for example by a finger). Make sure nothing
is blocking the lens.
- There is too much light (the camera in the Chatpen may have
problems interpreting the pattern in, for example, bright sunlight).
Try a shadier place.
- You are using an ink cartridge with unacceptable ink. See
“Technical data” on page 23.
- The printing quality is poor. Try another paper.
- There is dirt on the lens. Hold the pen with the lens facing upwards
under a strong lamp to clearly see the lens surface. Remove dust
and loose particles by blowing carefully at the lens, preferably
using a can of pressurised air duster. If the surface of the lens
is smeared with grease or other liquids, use a small cotton bud
moistened with alcohol to remove it. Note: Do not use acetone.
Sending
• An error message appears on the phone when trying to send
The cause can be one of the following:
- The service provider settings are wrong (only if an error message
appears the first time you try to send). Enter the settings again.
Tick again.
- Network problems. Turn off the phone, and turn it on again.
Tick again. If using GPRS (General Packet Radio Services),
check that the GPRS symbol shows in the display.
- The Internet connection is not working for the moment. Try to
tick at a later time.
- GPRS is not supported, if abroad for example. Contact your
service provider for instructions.
• This paper is not supported appears on the phone when trying
to send
The paper you used may be old, and the pen cannot interpret the
pattern. Use another notepad.
• No vibration or phone feedback when ticking
The pen did not interpret the tick. Tick again. If the problem
persists, reset the pen and tick again.
