Adjusting The Image Focus; Adjust Image Focus In Original Table Mode/Dspf Front-Face Mode (Ccd) - Sharp MX-M550U Service Manual

5) Adjust by turning the DSPF skew adjusting screw on the right
side of the DSPF rear frame.
Remove the hexagon cap nut of the DSPF skew adjusting
screw on the right side of the DSPF hinge and loosen the fixing
nut, then adjust by turning the DSPF skew adjusting screw
(hexagon screw).
If a < b, then turn counterclockwise the DSPF skew adjusting
screw (hexagon screw). (When the main scanning direction
print line is shifted to the left)
If a > b, then turn clockwise the DSPF skew adjusting screw
(hexagon screw). (When the main scanning direction print line
is shifted to the right)
Repeat steps 2 to 5 until an acceptable result is obtained.
[If the copied image of the paper's back side is skewed
beyond the acceptable level, do the following steps.]
6) Remove the DSPF front cover.
7) Change the front frame side CIS fixing position (angle) to
adjust the skew of the copied image of the paper's back side.
This adjustment should be done by loosening the CIS fixing
screw on the DSPF front side and then moving the fixing plate
in the left or right direction.
If c < d, then shift the CIS fixing plate to the right. (When the
main scanning direction print line is shifted to the left)
If c > d, then shift the CIS fixing plate to the left. (When the
main scanning direction print line is shifted to the right)
Repeat steps 2 to 7 until an acceptable result is obtained.
