When making test exposures, follow the instructions on page 11 - 8 for positioning the
plexiglass plates and measuring the density.
Start with 60 mm plexi and compress. Make sure that the display indicates at least
60 mm. Make an exposure and measure the optical density. Repeat this procedure with
50 mm, 40 mm and 20 mm plexi.
Change density with the density setting buttons on the control panel as needed (the panel
programming switch must be ON, see Service PC program Configuration, Miscella-
neous, Panel programming). The optical density for the four different programs shall be
as near as possible to 1.5 O.D. (or the density preferred by the customer). Store with the
memory button.
