Use a half tone document,
and make a 100% copy on
A4 or 8 1/2" x11" paper.
Check the uniformity.
Is the uniformity OK ?
Put the scale to the document
reference plate and set in the
papertransport direction.
Set Sim 50-1 set values
A and B to zero.
Make a copy on A4 or
8 1/2" x 11" paper at the
max. and the min.ratios in
the document table mode.
Measure the distance between
the copy image lead edge and
the paperlead edge of each copy.
L1: Distance at the max.
enlargement ratio.
L2: Distance at the min.
reduction ratio.
Calculate Sim 50-1 set values
from the following formula:
A = 11.545 x (L1 - L2)
B = 11.284 x L2 ~ 5.602 x L1
Set Sim 50-1 A and B.
Change the installing
position of the exposure
adjustment plate
toadjust the uniformity.
Make copies at the max.
and the min. ratios.
Measure the distance between
the copy image lead edge and
the copypaper lead edge of each
copy, and compare the two.
Make a 100% copy with
Sim 50-1 A.
Measure the copy image
lead edge and the copy
paper lead edge.
Change Sim 50-1 set
value A so that so that
the difference iswithin
the specified range.
Change Sim 50-1 set
value B so that so that
the difference is within
the specified range.
Make a 100% copy in the
document table mode,
and check the leadedge
void area.
Change Sim 50-1
(Lead edge void area
adjustment mode) set
value toadjust the void
area.
Make a 100% copy on A4
or 8 1/2" x 11" paper with
the documentcover opened,
and check the rear edge
void area.
Change Sim 50-1
(Rear edge void area
adjustment mode) set
value toadjust the rear
edge void area.
