Make a test chart. (Draw a
rectangular on A4 or
8 1/2" x 11"paper.)
Make a 75% copy on A4 or
8 1/2" x 11" paper with the
document coveropened.
Check horizontal image
distortion.
Make a 100% copy on A4
or 8 1/2" x 11" paper with
the documentcover opened.
Check that the right corner
and the left corner angles
of the copyimage are right
angles.
Make a 100% copy on A4
or 8 1/2" x 11" paper with
the documentcover closed.
Check copy image vertical
distortion.
Make a test chart. (Draw a
rectangle at the center of
B4 or 8 1/2" x 14" paper in
the longitudinal direction.)
Set the test chart to the
reference position, and
make a manualcopy (100%)
on A4 or 8 1/2" x 11" paper.
Check that the copy image
is at the center of paper.
Is the copy
image at the center
of paper ?
Change the relative
positions of the rear or
front frame sidescanner
drive pulley and the
shaft, and adjust
horizontal
imagedistortion.
Change the height
balance of right and
left scanner side rails,
andadjust so that the
corner angles of the
copy image rectangle
areequal to each other.
Change No. 4/5 mirror
height balance and
adjust vertical
magedistortion.
Change the lens holder
position so that the
copy image comes at
thecenter of the copy
paper.
Use the test chart
(UKOG-0089CSZZ) or the resolution
chart, andmake a 100% copy on A4
or 8 1/2" x 11" paper so that the
resolutionpatterns are copied
at the center and the four corners.
Check the resolution at the
center and the four corners.
Set the scale along the
document reference plate
(vertical to thepaper transport
direction), and make a 100%
copy on A4 or 8 1/2"x11" paper.
Compare the scale and
the copy image size.
Are they the
same size ?
Set the scale in the paper
transport direction, and
make a 100%copy
on A4 or 8 1/2" x 11" paper.
Compare the scale and
the copy image size.
Are they the
same size ?
Change No. 4/5 mirror
position to adjust focus.
Set Sim 48-1 set value
(vertical copy magnification
adjustmentmode) smaller.
Is the copy
image greater than the
actual size ?
Set Sim 48-1 set value
(horizontal copy
magnification
ratioadjustment mode)
smaller.
Is the copy
image greaterthan the
actual size ?
Set Sim 48-1 set value
(vertical copy magnification
ratioadjustment mode) greater.
Set Sim 48-1 set value
(horizontal copy
magnification ratioadjustment
mode) greater.
The distances
at the right and the left of
the horizontal copy lineand
the black background made
by the blank lamp are
equal toeachother.
Is the right corner
angle of the copy image
equal to the leftcorner
angle ?
Are the four
angles of the copy
image rectangle
right angle ?
Is the center
resolution more than 5.0
lines/mm and are the
cornerresolutions more
than 4.5 lines/mm ?
