Measurements of Projections

To determine a particular scale of a projected
image, mount a 6” ruler next to the copy or draw
1” grid lines onto the copyboard itself. If specifi c
enlargements are frequently used from common
originals, mark the fl oor with tape. Position the
tape at desired distances and mark the image size
directly on the tape for future reference (i.e. 10x).
Then simply align the cart, Projector Floor Stand (see
Accessories Section of this manual), or table with the
tape mark to attain that size.

Minimizing Distortion

Distortion is largely created when the projector is not
projecting squarely (perpendicular) onto the desired
surface. Imagine shining a fl ashlight onto a wall. If
the fl ashlight is shining straight ahead, the light is a
round circle. If the fl ashlight is turned to an angle,
either up or down or back and forth, the circle of
light is distorted. This same concept applies with a
projector. To minimize distortion, always keep the
projector level and the image square to the wall,
canvas or other vertical surface.

Projector Maintenance

Lens

Clean the lens with any lens cleaner and soft cloth or
lens tissue. Apply cleaner to the cloth – NEVER apply
cleaner directly onto the lens, as it may seep inside.

Mirror/Lamps

To clean mirror or replace lamps, fi rst
disconnect power supply.
Loosen plastic screw near the back of the projector
next to the top glass with a coin or screwdriver.
Remove top glass and set aside.

Mirror

The Super Prism has a special front-surface mirror
which eliminates double imaging and enhances
brightness. Clean its silvered surface with care,
using a mild cleansing solution and a soft cloth or

tissue. DO NOT scrub.

Lamps

The Super Prism uses two each of a 250 watt ECA
photo lamp. Replacement lamps can be ordered
from an Artograph dealer, direct from our factory, or
from your local bulb supplier or camera supply store.
