Were not trying to be funny here, but the lifespan is expressed in kilometers! Now what could that possibly mean?
The component most subject to wear is the roller on the tip of the pen scanner. (This very necessary part functions as a start switch and allows to detect the scanning speed.) Lab tests have indicated a lifespan of 6 kilometers. How quickly a user has scanned 6 km. of text – scanning an A4 page in landscape gives you 11(27.9 cm) – is anybodys guess. And it all depends on the frequency of use anyway. In practice, theres no need to panic: the first pen scanners were sold in the beginning of 1995. Our after sales service is happy to report that only very rarely are pen scanners exchanged or renewed.
