Light intensity correction for enlargement and reduction modes
The halogen lamp light intensity for enlargement and reduction modes is determined by the
value for copying at 100% magnification and the correction values set by simulation 29.

Figure 1-3-17 Correction of light intensity for reduction and enlargement modes
The correction values for reduction (64%) and enlargement (141%) copying are linked by
a straight line through the value for 100% magnification, and the light intensity is corrected
for individual magnification ratios according to the gradients.
Light intensity correction by the user setting
The light intensity data can be corrected in exposure adjustment of the user settings by
pressing an exposure adjustment key in manual exposure mode or the auto/manual
exposure key in auto exposure mode for 5 s. The light intensity correction value is 0 at Exp.
4 and changes at 4 bits per 0.5 steps of the exposure scale.
