AR-M205 ADJUSTMENT 6-7
1) Making of a test sheet
Make test sheet by drawing parallel lines at 10mm from the both
ends of A3 (11" x 17") white paper as shown below. (These lines
must be correctly parallel to each other.)
2) Make a normal (100%) copy of the test sheet on A3 (11" x 17")
paper. (Fit the paper edge with the glass holding plate edge.)
3) Measure the distances (La, Lb, Lc, Ld) at the four corners as shown
below.
When La = Lb and Lc = Ld, no need to perform the procedures 4) and 5).
4) Move the mirror base F rail position up and down (in the arrow
direction) to adjust.
Note: If the rear side rail is used for the adjustment, the scanning position
of the white balance sheet is shifted and "E7-04" may occur only
when scanning with the SPF. Therefore it is advisable to use the
when scanning with the SPF. Therefore it is advisable to use the
front side rail for the adjustment.
<Adjustment specification>
La = Lb, Lc = Ld
5) After completion of adjustment, manually turn the mirror base drive
pulley, scan the mirror base A and mirror base B fully, and check that
the mirror bases are not in contact with each other.
*
If the mirror base rail is moved extremely, the mirror base may be in
contact with the frame or the original glass. Be careful to avoid this.
(5) Main scanning direction (FR direction) magnification
ratio adjustment (SIM 48-1)
Note: Before performing this adjustment, be sure to check that the CCD
unit is properly installed.
1) Put a scale on the original table as shown below.
2) Execute SIM 48-1.
