2 PRECAUTIONS FOR INSTALLATION
Installation Site
To ensure safety and utmost performance of the copier, the copier should NOT be used in a
place:
•
Where it will be subject to extremely high or low temperature or humidity.
•
Which is exposed to direct sunlight.
•
Which is in the direct air stream of an air conditioner, heater or ventilator.
•
Which puts the operator in the direct stream of exhaust from the copier.
•
Which has poor ventilation.
•
Where ammonia gas might be generated.
•
Which does not have a stable, level floor.
•
Where it will be subject to sudden fluctuations in either temperature or humidity. If a cold
room is quickly heated, condensation forms inside the copier, resulting in blank spots in
the copy.
•
Which is near any kind of heating device.
•
Where it may be splashed with water.
•
Which is dirty or where it will receive undue vibration.
•
Which is near volatile flammables or curtains.
Power Source
Use an outlet with a capacity of 115V, 1.18KW or more, or 120V , 1.22KW or more, or 120127V, 1.29KW or more, or 220
•
If any other electrical equipment is sourced from the same power outlet, make sure that
the capacity of the outlet is not exceeded.
•
Use a power source with little voltage fluctuation.
•
Never connect by means of a multiple socket any other appliances or machines to the
outlet being used for the copier.
•
Make the following checks at frequent intervals:
✽
Is the power plug abnormally hot?
✽
Are there any cracks or scrapes in the cord?
✽
Has the power plug been inserted fully into the outlet?
✽
Does something, including the copier itself, ride on the power cord?
•
Ensure that the copier does not ride on the power cord or communications cable of other
electrical equipment, and that it does not become wedged int o or underneath the mechanism.
–
240V, 1.27KW or more.
Grounding
To prevent receiving electrical shocks in the case of electrical leakage, always ground the
copier.
•
Connect the grounding wire to:
✽
The ground terminal of the outlet.
✽
A grounding contact which complies with the local electrical standards.
•
Never connect the grounding wire to a gas pipe, the grounding wire for a telephone, or a
water pipe.

3 PRECAUTIONS FOR USE
To ensure that the copier is used in an optimum condition, observe the following precautions.
•
Never place a heavy object on the copier or subject the copier to shocks.
•
Insert the power plug all the way into the outlet.
•
Do not attempt to remove any panel or cover which is secured while the copier is making
copies.
•
Do not turn OFF the Power Switch while the copier is making copies.
•
Provide good ventilation when making a large number of copies continuously.
•
Never use flammable sprays near the copier.
•
If the copier becomes inordinately hot or produces abnormal noise, turn it OFF and
unplug it.
•
Do not turn ON the Power Switch at the same time when you plug the pow er cord into the
outlet.
•
When unplugging the power cord, do not pull on the cord; hold the plug and pull it out.
•
Do not bring any magnetized object near the copier.
•
Do not place a vase or vessel containing water on the copier.
•
Be sure to turn OFF the Power Switch at the end of the workday or upon power failure.
•
Use care not to drop paper clips, staples, or other small pieces of metal into the copier.
Operating Environment
The operating environmental requirements of the copier are as follows.
✽
Temperature: 10°C to 30°C with a fluctuation of 10°C per hour
✽
Humidity: 15% to 85% RH with a fluctuation of 10% RH per hour
Power Requirements
The power source voltage requirements are as follows.
✽
Voltage Fluctuation:
✽
Frequency Fluctuation:
AC115/120/127/220/240V
±10% (Copying performance assured)
+6%, –10% (Only AC127V)
–15% (Paper feeding performance assured)

4 HANDLING OF THE CONSUMABLES
Before using any consumables, always read the label on its container carefully.
•
Use the right toner. The applicable copier model name is indicated on the Toner Bottle.
•
Paper is apt to be easily damaged by dampness. To prevent absorption of moisture, store
paper, which has been removed from its wrapper but not loaded into the Drawer, in a
sealed plastic bag in a cool, dark place.
•
Keep consumables out of the reach of children.
•
Do not touch the PC Drum with bare hands.
•
Store the paper, toner, and other consumables in a place free from direct sunlight and
away from any heating apparatus.
•
The same sized paper is of two kinds, short grain and long grain. Short grain paper
should only be fed through the copier crosswise, long grain paper should only be fed
lengthwise.
•
If your hands become soiled with toner, wash them with soap and water immediately.
•
Do not throw away any used consumables (PC Drum, starter, toner, etc.). They are to be
collected.
NOTE
Do not burn, bury in the ground, or throw into the water any consumables
(PC Drum, starter, toner, etc.).

7. IMAGE TRANSFER
1. PC Drum
The PC Drum is an aluminum cylinder coated with a photosensitive semiconductor.
It is used as the medium on which a visible developed image of the original is formed.
(For more details, see “6. PC DRUM”.)
2. Drum Charging
The PC Drum Charge Corona Unit is equipped with a Comb Electrode and a Scorotron
Grid to deposit a uniform negative charge across the entire surface of the PC Drum.
(For more details, see “7. DRUM CHARGING”.)
3. Image Erase
Any areas of charge which are not to be developed are neutralized by lighting up LEDs.
(For more details, see “8. IMAGE ERASE LAMP”.)
4. Exposure
Light from the Exposure Lamp reflected off the original is guided to the surface of the PC
Drum and reduces the level of the negative charges, thereby forming an electrostatic
latent image.
(For more details, see “9. OPTICAL SECTION”.)
5. Developing
Toner positively charged in the Developer Mixing Chamber is attracted onto the electrostatic latent image changing it to a visible, developed image . A DC negative bias voltage is
applied to the Sleeve/Magnet Roller to prevent toner from being attracted onto those
areas of the PC Drum which correspond to the background areas of the original.
(For more details, see “11. DEVELOPMENT”.)
M-4
FrameMaker Ver.5.5(PC) EP1054/EP1085/EP2030 MECHANICAL/ELECTRICAL
98.04.24
6. Paper Feeding
Paper is fed either automatically from the 1st or 2nd Drawer, or manually via the Multi
Bypass Table or Manual Bypass Table. Each Drawer has fingers that function to separate
the top sheet of paper from the rest at take-up. (2nd Drawer: 23 cpm Copier Only)
(For more details, see “13. PAPER TAKE-UP/FEED SECTION”.)
7. Image Transfer
The single-wire Image Transfer Corona Unit applies a DC negativ e corona emission to the
underside of the paper, thereby attracting toner onto the surface of the paper.
(For more details, see “16. IMAGE TRANSFER AND PAPER SEPARATION”.)
8. Paper Separation
The single-wire Paper Separator Corona Unit applies an AC corona emission to the
underside of the paper to neutralize the paper. In addition, mechanical paper separation is
provided by the two PC Drum Paper Separator Fingers fitted to the Imaging Unit.
(For more details, see “16. IMAGE TRANSFER AND PAPER SEPARATION”.)
9. Cleaning
Residual toner on the surface of the PC Drum is scraped off by the Cleaning Blade.
(For more details, see “19. CLEANING UNIT”.)
10. Main Erase
Light from the Main Erase Lamp neutralizes any surface potential remaining on the surface of the PC Drum after cleaning.
(For more details, see “17. MAIN ERASE LAMP”.)
11. Transport
The paper is fed to the Fusing Unit by the Suction Belts.
(For more details, see “20. PAPER TRANSPORT”.)
12. Fusing
The developed image is permanently fused to the paper by a combination of heat and
pressure applied by the Upper and Lower Fusing Rollers.
(For more details, see “21. FUSING UNIT”.)
13. Paper Exit
After the fusing process the paper is fed out by the Paper Exit Roller onto the Copy Tray.
(For more details, see “22. EXIT UNIT”.)

3 DRIVE SYSTEM
This copier is equipped with two main drive motors, the PC Drive Motor that drives the
upper half of the copier (Imaging Unit) and the Main Drive Motor which gives drive f or the
lower half of the copier (paper take-up/feeding, transport mechanism and Fusing Unit).
Each has its own drive transmitting gears and timing belts as illustrated below.
