1. Installing (use) conditions
Before installing the machine, check that the following installing
(use) conditions are satisfied.
If the installing (use) conditions are not satisfied, the machine may
not display full performances, resulting in troubles. It may also
cause safety problems. Therefore, be sure to arrange the installing
(use) conditions before setting up the machine.
A. Delivery notes
For installation of a large size machine, be sure to check that the
door size is great enough before bringing in.
B. Installation area
The following space must be provided around the machine in order
to assure machine performances and proper operations.
If any option is installed, provide the additional space for installing
it.
Especially the space at the rear of the machine must be provided
sufficiently. If not, the machine cannot exhibit functions against heat
and dust, causing some troubles.
C. Power source (Capacity, voltage, frequency,
safety, plug)
If the power specifications are not satisfied, the machine cannot
exhibit full performances and may cause safety trouble.
Strictly observe the following specifications.
(1) Power capacity
Check that the following power capacity is satisfied. If not, addition-
ally provide a power source.
(2) Power voltage
Measure the voltage during copying to check that the voltage is in
the range of the specified voltage ±10%.
If the voltage is outside the specified range, use thicker lead wires
to reduce impedance.
(An electrical work is required.)
Use of a step-up transformer is also available. In this case, the
capacity must be great enough for the max. power consumption of
the machine.
(3) Power frequency, waveform
The frequency must be within the range of the specified frequency
±2%. If power waveform is deformed, a trouble may occur.
(4) Safety
Be sure to properly ground the machine.
(5) Power plug
Check the form of the power plug. If the shape does not match, do
not use it.
D. Floor strength and level
This machine is considerably heavy and becomes heavier with an
option installed. The floor must be strong enough for assuring
safety.
If the floor is not level, the toner density control is not normal, and
the copy quality may be adversely affected.
E. Environmental conditions
(1) Temperature and humidity
This machine is designed to perform properly under the specified
temperature and humidity. If the temperature and humidity exceeds
the specified range, the machine may not operate properly and or
cause equipment failure.
Especially when the humidity is too high, paper absorbs humidity to
cause a paper jam or dirty copy.
Do not install the machine near a heater, a cooler, or a humidifier.
Dew may be formed inside the machine to cause a trouble. Use
enough care for ventilation.

this adjustment.
To check and adjust the K (black) image skew, follow the
procedures below and execute the adjustment.
1) Enter SIM61-4 mode.
2) Select the paper feed tray with A3 (11" x 17") paper in it by
changing the value of set item B.
3) Press [EXECUTE] key.
The check pattern is printed out.
4) Check the printed black image for any skew.
Measure the right angle level by using the six cross patterns
printed in black.
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 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.
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.
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.
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.)
9) If the adjustment result reaches the satisfactory level, tighten
the adjustment screw.
(The black image skew adjustment is completed with the
above.)
10) In the above black image skew adjustment, check the color
image skew pattern printed when completion of the adjust-
ment.
*A: Rough adjustment print pattern
*B: Fine adjustment print pattern
In each Y/M/C color print pattern printed separately in the front
frame direction and in the rear frame direction, note the same
print color pattern and check to confirm that the difference in
the highest density sections is within ±1 step.
(Compare the front and the rear frame positions of the same-
color print color patterns. All the highest density sections of all
the print color patterns may not be aligned on a line. Compare
only the same-color patterns.)
If the above condition is not met, do the following:

11) Turn the image skew adjustment screw of the target color to
adjust.
When each adjustment screw is turned, it clicks. Turn it by
5 - 6 clicks and the check pattern is changed by 1 step (1
dot size).
When the image skew pattern on the front frame side is
skewed in the arrow direction of A (to the smaller number) from
the rear frame side, turn the adjustment screw counterclock-
wise. When the image is skewed in the arrow direction of B (to
the larger number), turn the adjustment screw clockwise.
12) Print the check pattern.
13) Check the color image skew pattern.
Repeat procedures 11) - 13) until a satisfactory result is obtained.
The image skew adjustment (LSU unit) is executed by changing

[EXECUTE] key.
The copy color balance adjustment is automatically executed
and prints the color balance check patch image.
If there is any streak or unclear print on the printed check pat-
tern, check the print engine for any problems.
Remark:
(Descriptions on the factory service key button in the color bal-
ance automatic adjustment menu)
There are two kinds of the gamma target for the color balance
automatic adjustment: the factory target and the service target.
FACTORY key and SERVICE key are used to select one of the
above two.
Factory target color balance: Standard color balance
(The color balance can be selected from the three kinds of
fixed ones with SIM63-11.)
Service target color balance: The color balance can be cus-
tomized according to the user's request. (Variable)
When shipping from the factory, the service target gamma data
and the factory target gamma data are the same.
Both are set to the standard color balance when shipping from
the factory. For the service target, a customized color balance
gamma can be registered with SIM63-7.
