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. Bringing space
For installation of a large size machine, be sure to check that the
door size is wide enough before bringing in.
B. Installing space
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.
Adequate space must be provide behind the machine for proper
ventilation heat and dust. If not, the machine cannot exhibit func-
tions 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.
Current capacity
Japan: 20A or more
100V: 15A or more
200V: 10A or more
Check the shape of the power plug of the machine, and insert it into
a power outlet of the acceptable shape.
(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.

the power plug into the power outlet.
When disconnecting the earth connection, be sure to disconnect
the power plug from the power outlet in advance.
(5) Power plug
Check the shape of the power plug of the machine, and insert it into
a power outlet of the acceptable shape.
Power plug stated in power capacity.
D. Floor strength and level
This machine is considerably heavy and becomes heavier with an
option installed.
The floor must be strong enough to safely support the weight of the
machine as well as any installed options.
If the unit is not horizontally installed, the toner density control is
not performed normally, degrading the copy quality.
If not, color shift or image distortion may occur.
To assure proper Image quality, make sure the machine is setting
level.
E. Direct rays of the sun, dust, temperature,
humidity, gasses, chemicals, vibration
(1) Temperature and humidity (Environmental
conditions)
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.
Condensation may form inside the machine causing multiple trou-
bles. Use enough care for ventilation.

power outlet.
2) Turn ON the main power switch of the machine and the power
switch on the operation panel.
3) Enter the SIM25-2 mode.
4) After entering the simulation, close the front cabinet.
5) Select K, C, M, Y and then press the [EXECUTE] button. The
system then performs the simulation, samples the toner den-
sity control sensor value, and sets (stores in memory) the
average sensor detection level as the control level for the ref-
erence toner density. (Operating times: approx. 1.5 minutes)
Be sure to select all of the four colors: K, C, M, Y.
6) After the machine completes cycling, exit the simulation mode
by pressing the [CA] key on the main unit.
C. Cleaning
(1) Cleaning of LSU's dust-proof glass
Dust from the transfer belt or shutter or some other adjacent part
may fall onto the LSU during transport or installation. Be sure to
clean the dust-proof glass before checking the image quality.
1) Open the front cabinet. Slide the lock to release, and remove
the waste toner box.
2) Detach the LSU cleaning bar from the front cover.

(2) Copy color balance and density check
Before checking the copy color balance and density, be sure to
execute the following jobs.
* Execute the high density image correction (Process correction)
forcibly. (SIM 44-6)
* Execute the half-tone image correction forcibly. (SIM 44-26)
Method 1
Make a copy of the gray test chart (UKOG-0162FCZZ) and a copy
of the servicing color test chart (UKOG-0326FCZZ/UKOG-
0326FC11), and check that they are proper.
a. Note for execution of the color balance and density check in the
color copy mode
To check the copy color balance and density, use the gray test
chart (UKOG-0162FCZZ) and the servicing color test chart
(UKOG-0326FCZZ/UKOG-0326FC11). Set the copy density
level to "3" in the Text/Printed Photo mode (Manual), and make a
copy.
At that time, all the color balance adjustments in the user adjust-
ment mode must be set to the default (center).
In addition, be sure to use the specified paper for color.
b. Note for checking the monochrome copy mode density
To check the density, use the gray test chart (UKOG-0162FCZZ).
Set the copy density level to "Manual 3" in the Text/Printed Photo
mode (Manual).
In addition, all the color balance adjustments in the user adjust-
ment mode must be set to the default (center).
[Check with the gray test chart (UKOG-0162FCZZ)]
In the copy density check with the gray test chart, check to insure
the following conditions.
For the color (gray) balance, use the servicing color test chart
(UKOG-0326FCZZ/UKOG-0326FC11) to check.

Method 2
Use SIM46-21 to print the color balance adjustment sheet, and
check each process (CMY) black patch color balance and the black
patch in order to confirm that the color balance adjustment is
proper.
If the color balance of each patch of the process black (CMY mixed
color) is slightly shifted to Magenta, it means that the adjustment is
proper. If the color balance of the adjustment pattern printed in this
mode is slightly shifted to Magenta, it is converted into the natural
gray color balance by the color table in an actual copy mode.
(When the color balance target is DEF 1.)
If color balance or density is not satisfied, adjust the copy and
printer color balance by SIM 46-74.
(3) Printer color balance/density check
Before checking the printer color balance and the density, be sure
to execute the following procedures in advance.
* Execute the high density image correction (Process correction)
forcibly. (SIM 44-6)
* The half-tone image correction is forcibly executed. (SIM 44-26)
Method 1
Execute SIM 64-5 to print the print test pattern.
When the PCL or the PS printer function is not provided in case of
GDI printer, this method cannot be used for check.
Set each set value to the default and press [EXECUTE] key. The
print test pattern is printed.
The print density must be changed gradually from the lighter level
to the darker level. The density changing direction must not be
reversed. The density level of each color must be almost at the
same level.
Method 2
When the PCL or the PS printer function is not provided (GDI
model), use this method for check.
Use SIM 67-25 to print the color balance adjustment sheet and
compare each process (CMY) black patch color balance and the
black patch to check the color balance.
The print density must be changed gradually from the lighter level
to the darker level. The density changing direction must not be
reversed.
The density level of each color must be almost at the same level.
Patch B may not be copied.
Patch A must not be copied.
If the color balance of each patch of the process black (CMY mixed
color) is slightly shifted to Magenta, it means that the adjustment is
proper. In an actual print mode, it is converted into the natural gray
color balance by the color table. (When the color balance target is
DEF 1.)
