noticeable.
C
heck image to top of plate accuracy as follows:
1.
Expose
4
plates with a 50% tint stock image.
2.
Move the image (usually set at
2 mm
) as
close
as possible
to the top
edge of the plate using the following method:
A
)
Adjust the IMAGE_BASE_OFFSET value in the diagnostics/
service/optics/mmi> machine setup screen after noting the
original value to be restored.
B
)
For instance, if the value is approximately
1339850
microns,
move it closer to the plate edge by subtracting
2000
microns
(
1337850
).
C
)
Adjust the gap +/- a few microns to obtain a measurable
difference.
3.
Using a x50 eyeglass, measure the gaps,
A
and
B
, at the widest reg
pin positions (259, 305 or 470 mm), see
Figure 5.16 on page 5-27
.
