(5) Fine Start Mode
This mode automatically sets optimum values for the following start conditions: timing of ink roller actuation
during platemaking, number of no-paper rotations with the ink roller actuated.
These optimum settings are based on room temperature, the length of time the printer was out of use, and the
number of prints last time it was used. They ensure clear printing right from the first sheet after platemak-
ing.
*Room temperature of 10 ; or below can cause insufficient ink supply, even in Fine Start.
