Method 2:
Compare the right angle of vertical side/horizontal side of the
rectangle print pattern and the right angle sides of A3 or 11 x
8.5 paper for judgment of good or no good.
(NOTE) In the case of Method 2, the right angle of paper to be
used may not be exact. Be sure to check the right angle of
paper to be used in advance.
(Method 1)
a) Measure the length of the diagonal lines of the rectangle
print pattern.
Diagonal line D
Diagonal line C
b) Calculate the difference between the measured lengths C
and D of the diagonal lines.
c) Check to insure that the difference between C and D is in
the following range. C – D = ±0.8mm
If the difference between C and D is in the above range, there
is no need to adjust.
(Method 2)
a) Fit the side of A3 or 11" x 17" paper to the long side of the
rectangle print pattern.
Comparison line
A3 or 11 x 17 paper
0.5mm or less
b) Measure the shift distance between vertical side of paper
and side of the rectangle print pattern.
If the above distance is 0.5mm or less, there is no need to
adjust.
If not, execute the following procedures.
5) Open the front cabinet, and remove the waste toner box.
(For U.S.A. 50-sheet machine only)
Remove the power switch cover.

6) Loosen the LSU unit fixing screws (2 pcs.) and shift the skew
adjustment screw in the arrow direction to adjust the LSU (writ-
ing) unit skew.
(When Method 1 is used to check the black image for any
skew (right angle) in procedure 4 in advance)
When the lengths of the diagonal line are C > D, shift the
adjustment screw in the direction of Y.
When the lengths of the diagonal line are C < D, shift the
adjustment screw in the direction of X.
(When Method 2 is used to check the black image for any
skew (right angle) in procedure 4 in advance)
If the image is skewed in the arrow direction of A, shift the
adjustment screw to X direction. If the image is skewed in the
arrow direction of B, shift the adjustment screw to Y direction.
7) Install the waste toner box, and close the front cabinet.
8) Execute procedures 3) - 4).
(Repeat procedures 5) - 8) until a satisfactory result is
obtained.)
