Since this machine is easy to operate and efficient, many times you find
it in the selfhelp area of a VI facility, or used to produce low
priority, shortsuspense requirements. This process requires only four
steps to produce a viewgraph (figure 212).
Figure 212. Thermofax production steps
a. Adjust the Exposure. The exposure knob has numbers ranging from
1 to 12, with 1 being the lightest setting. The setting of the control
determines the density of the viewgraph. Experience serves as the best
teacher for learning the exposure setting required to produce a quality
viewgraph. When you have this experience, you can look at the density
and quality of the original and determine the correct exposure setting.
b. Position the Film. To produce a quality viewgraph, you must
have the slipsheet, film, and original in the proper order. Starting
from the bottom up, the slipsheet is first, followed by the original
laying face up, and then the film with the notched corner or arrow in
the upper righthand corner.
c. Inserting the Film. Center the materials (slipsheet, original,
and film) as a group and insert them into the
