Optimizing The Delays

The following figures show the various effects of
non-optimized delays on the letters "RTC".

LaserOn Delay too short

At the beginning of a mark vector
the laser is switched on, even
though the mirrors have not yet
reached the necessary angular
velocity.

Burn-in effects at the start points
of the respective vectors result.

LaserOn Delay too long

The laser is turned on too late at
the beginning of a mark vector.

The first part of the vector is not
marked.

LaserOff Delay too long

The laser is turned off too late
after the last mark command of a
line or polyline. The laser is still
on, even though the mirrors have
already stopped or move only
very slowly.

The results are burn-in effects at
the end points of the respective
vectors.

LaserOff Delay too short

The laser is turned off after the
last mark command of a line or
polyline, although the mirrors
have not yet reached the end
position of the vectors.

The respective vectors are not
marked completely.
