3)
Turn the lock lever to the horizontal position to release the
lock, and open the drum positioning plate unit.
4)
Shake the developer cartridge 5 - 6 times horizontally, and
remove the protection material from the developer cartridge.

magnet roller section and the shutter section.
5)
While pressing the developer cartridge, pull out the heat seal
straight.
NOTE: If the heat seal is pulled out with a strong force or diago-
nally, it may be broken off. Be sure to pull it slowly and
straight.
After puling out the heat seal completely, check to confirm
that there is a red mark at the edge of the heat seal.
If there is no red mark, it means that the heat seal has been
broken. In such a case, the developer cartridge must be
replaced with a new one.

NOTE: When the machine is transported with the developing unit
removed, be sure to remove the toner cartridge. (if not
toner may become clogged.)
NOTE: Do not remove or insert the toner cartridge with the devel-
oper cartridge removed.
C. Cleaning of LSU's dust-proof glass

may fall onto the LSU during transport or installation. Be sure to
clean the dust-proof glass before checking the image quality.
1)
Remove the LSU cleaning rod from the front cover.
2)
Face the cleaner downward, and slowly insert the LSU clean-
ing rod into the LSU cleaning hole.
* The LSU cleaning hole is indicated with a label.

3)
Insert the tray slowly.
The machine automatically detects the set paper size.
F. Specifications setting

request.
To customize one of the following items after destination setting,
change the set value of the item.

(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.

Enter SIM61-4 mode.
(4.3 Inch LCD model)
(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).
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
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.
(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.
(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.
