2. Installation
Installationconditions
The following installing conditions must be satisfied to assure the
normal operations of the machine.
(1) Environment
1Keep the machine away from direct sunlight and avoid instal-
lation near a window or in a bright place.
(Draw the curtain and close the blind shutter completely.)
The plastic parts and the original cover may be deformed by direct
sunlight. Avoid installation near a window even with frosted glass.
2Avoid installation in high temperature or high humitity en-
vironments. Also, avoid installation where temperature or
humidity may change quickly. (e.g., near an air conditioner).
Otherwise copy papers may be dampened and condensation may
be generated in the machine. This may result in paper jams or
poor copy quality.
(Ideal conditions): The best suitable conditions for machine
operation:
20°C∼25°C: 65 ±5%RH
(Temperature/humidity range): 15°C ∼30°C (59°F ∼86°F),
20% ∼85%
65% for 35°C (95°F)

Humidity

15 30 35
˚C
(59˚) (86˚) (95˚) (˚F)
4 – 1

3Avoid installation where there is a lot of dust or vibrations.
If dust enters the machine, it may degrade copy quality and cause
malfunctions.
4Avoid installation on an unstable surface.
To assure the proper operations, install on a level surface.
5Install in a well ventilated place.
6Avoid installation where there is inflammable gases or am-
monium gases.
Installation near a diazonium copier may degrade copy quality and
cause malfunctions.
7Install near a power outlet.
(2) Space around the machine
Allow a space of about 15 cm (6 inches) between the rear side of the
machine and the wall for ventilation of the cooling fan. Also allow
sufficient space around the machine for operations.
(3) Installing table
Use a level (UKOGM0054CSZZ) to install the machine horizontal-
ly.
(Allowable tilt: 5 mm between the front and rear frames)
(Note) If the machine is not installed horizontally, toner density con-
trol may not function properly. This may result in poor copy
quality.
(4) Power source
1The power source should be the rated voltage ±10% with the
capacity corresponding to the max. power consumption.
2Do not use an extension cord, or operate any other equipment
from the same wall outlet.
(5) Grounding
To avoid electrical hazard, use the properly grounded wall outlet only.
(Carrying the machine)
When carrying the machine, remove the copy tray and hold the dent
portions on the bottom.
4 – 2

3. Installation procedure
(1) Optical system unlocking
1Unlock the No.2/No.3 mirror unit.
Remove the No.2/No.3 mirror unit fixing screw (1 pc.) on the left
side of the copier.
2Unlock the No.4/No.5 mirror unit.
Remove the No.4/No.5 mirror unit fixing screws (2 pcs.) on the
right side of the copier.
[In the case of SF-1014 with SF-MF14 (Optional) equipped.]
Open the paper feed tray on the right side of the copier.
Remove the No.4/No.5 mirror unit fixing screws (2 pcs.).
Then close the paper feed tray.
(2) Cassette setting
1Pull out the cassette.
Lift the cassette and slowly pull it out from the copier until it stops.
2Loading copy paper.
Set the copy papers in the cassette. Do not exceed the limit line
indicator.
Gently insert the cassette fully into the copier.

(3) Developer setting
1Open the front cabinet.
Push the front cabinet open buttons which are on the left and right
sides of the copier, and open the front cabinet.
2Open the toner cartridge.
While pressing the toner cartridge release lever (B), open the
toner cartridge.
3Remove the toner cartridge.
Slowly turn the toner cartridge clockwise to remove.
4Remove the developing unit.
Loosen the fixing screw (step screw) which is fixing the copier and
the developing unit, and slowly pullout the developing unit and
Lenz hold Plate from the copier.
5Remove the developer tank.
Slightly open the pawl which is fixing the developing unit and the
developer tank with a screw driver, and pull out the developer
tank.
6Supply developer.
Supply a bag of developer to the developer supply port of the
developing unit.
At that time, move the bag of developer to supply developer even-
ly.
7Install the developer tank.
Insert the developer tank to the developing unit along the guide of
the developing unit.
At that time, check that the developer tank is securely fixed in the
developing unit.
8Install the developing unit.
Slowly insert the developing unit into the copier along the guide of
the copier until it stops.
Tighten the fixing screw which was removed in procedure (D), and
fix the developing unit to the copier.

(4) Toner supply
1Shake the toner cartridge up and down.
Shake the toner cartridge up and down 9 to 10 times.
2Install the toner cartridge.
Install the toner cartridge to the copier along the guide of the
copier.
Turn the toner cartridge counterclockwise to lock.
3Supply toner.
Remove the sheet from the toner cartridge and supply toner.
Slowly return the toner cartridge to the original position.
4Close the front cabinet.
(5) Toner density sensor level check
1Turn on the power switch of the copier.
2Adjust the developer level.
(a) Perform the key operations of simulation 25 sub 2.
With the above key operations, simulation 25 is performed and
the developer is stirred for 3 minutes.
(b) After stirring the developer for 3 minutes, the toner density
level is read by the main PWB.
During stirring, the toner density sensor level is displayed on
the MULTI COPY display. (Range: 1 ∼99)
[Note] If the simulation is cancelled during execution, the
automatic reading cannot be performed. Do not cancel
the simulation during execution.
(c) Press the CLEAR key three times to cancel simulation 25.
(6) Accessory attachment
Attach the copy tray.
