(Meaning of the skew level)
* When "R" is attached in front of the value, turn the skew adjust-
ment screw (LSU) clockwise by the value (angle).
* When "L" is attached in front of the value, turn the skew adjust-
ment screw (LSU) counterclockwise by the value (angle).
NOTE: The black (K) image skew level cannot be checked with
SIM50-22.
1)
Enter SIM61-4 mode.

(8.5/7.0 Inch LCD model)
2)
Select the tray with A4 (11" x 8.5") paper in it.
3)
Press [EXECUTE] key.
The check pattern is printed out.
4)
Check the printed black image for any skew.
There are following two methods of checking the black image
for any skew (right angle).
for any skew (right angle).
Method 1:
Measure the length of the diagonal lines of the rectangle print
pattern. Check the difference in the length of the diagonal lines
for judgment of good or no good
Measure the length of the diagonal lines of the rectangle print
pattern. Check the difference in the length of the diagonal lines
for judgment of good or no good
Method 2:
Compare the right angle of vertical side/horizontal side of the
rectangle print pattern and the right angle sides of A4 (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.
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.
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.
is no need to adjust.
(Method 2)
a) Fit the side of A4 or 11" x 8.5" paper to the long side of the rectangle print pattern.
b) Measure the shift distance between vertical side of paper and side of the rectangle print pattern.
If the above distances (left and right) are 0.5mm or less, there is no need to adjust.
If not, execute the following procedures.
