Print the trim pattern using pattern 1 in SP5-955-018.
Then check that the margins on the trim pattern are
as follows:
Lead edge: 5mm (target) +/- 2 mm
Trailing edge: 2mm (target) +2mm/-1.5mm
Side (target): 1.5mm, Side (specification): 2+/-2mm.
Adjust the magnification in the sub scan direction first
using SP 2-113-02. Then print the trim pattern again.
Then adjust the magnification in the main scan
direction with 2-113-01.
Adjust SP2-113-02 (sub scan) first and print the trim
pattern again before adjusting 2-112-02 (main scan),
because SP2-113-02 also affects the main scan
magnification
Note: Do not adjust SP2-113-002 by more than +/-
0.5% at any one time.
