I would like to increase these timings but are either / both
likely to be in software rather than presets or similar.
Time unattended for m/c to revert to reset condition eg 140%
magnification reverts to 100%, exposure setting etc reset.
Also to lengthen the time between auto print run exposures so it would be
possible to turn pages and hold in place etc without
having to manually press the print buttonn
