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

or more.

If any other electrical equipment is

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 into or under-

neath the mechanism.

from the same power outlet, make sure

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.

G-6

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 power 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:

Humidity: 15% to 85% RH with a fluctuation of 10% RH per hour

10C

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.

l 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.).

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 origlnal is formed.

(For more details, see p. M-9.)

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 p. M-21

3. Image Erase

Any areas of charge which are not to be developed are neutralized by lighting up

(For more details, see p. M-22.)

LEDs.

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 p. M-24.)

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 p. M-12.)

6. Paper Feeding

Paper is fed either automatically from the 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.

(For more details, see p. M-34.)

7. Image Transfer

The single-wire Image Transfer Corona Unit applies a DC negative corona emission to the underside of the paper, thereby attracting toner onto the surface of the paper.

(For more details, see p. M-33.)

8. Paper Separation

The paper, thanks to its inherent strength, is naturally separated from the small-diameter PC Drum. This is combined with the application of a positive DC bias with a comb electrode. The two methods ensure that the paper is definitely separated from the surface of the PC Drum.

(For more details, see p. M-33.)

9. Cleaning

Residual toner on the surface of the PC Drum is scraped off by the Cleaning Blade.

(For more details, see p. M-l 8.)

10. Main Erase Lamp

The Main Erase Lamp applies a positive DC charge to neutralize any surface potential remaining on the surface of the PC Drum after cleaning.

(For more details, see p. M-32.)

11. Transport

The paper is fed to the Fusing Unit by the Guide Plate.

(For more details, see p M-45.)

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 p. M-46.)

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 p. M-49.)

The photoconductive drum used in this copier is the organic photoconductor

(OK)

type. The drum is made up of two distinct, semiconductive materials on an alumi-

num alloy base. The outer of the two layers is called the Charge Transport Layer (CTL), while the inner layer is called the Charge Generating Layer (CGL).

The PC Drum has its grounding point inside at its rear end. When the Imaging Unit

is installed in the copier, the shaft on which the PC Drum Drive Coupling Gear is mounted contacts this grounding point.

Handling Precautions

This photoconductor exhibits greatest light fatigue after being exposed to light over

an extended period of time. It must therefore be protected from light by a clean, soft

cloth whenever the Imaging Unit has been removed from the copier. Further, use

utmost care when handling the PC Drum to prevent it from being contaminated.
