Which puts the ope rator 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 fl oor.

•

Where it will be s ubject to sudden fluctuations i n either temper ature or humidit y. If a cold
room is quickly heated, conden sation forms ins i de the copier, result i ng in blank spots in
the copy.

•

Which is near any kind of heating device.

•

Where it may be splashed with water.

The following precautions must be observed when handling P.W. Boards with MOS
(Metal Oxide Semiconductor) ICs.

During T ransportation/Storage:

•

During transportation or when in storage, new P.W. Boards must not be indiscrimi nately
removed from their protective conductive bags.

•

Do not store or place P.W. Boards in a location exposed to direct sunlight.

•

When it becomes absol utely necessary to remove a Board from its conducti ve bag or
case, al ways place it on i ts conducti ve mat in an area as free as possible from static elec­tricity.

•

Do not touch the pins of the ICs with your bare hands.

During Replacement:

•

Before unpl ugging connect ors from the P.W. Boards, make sure that the power cord has
been unplugged f r om the outlet.

•

When removing a Board from its conductive bag or conductive case, do not touch the
pins of the ICs or the printed pattern. Place it in position by holding onl y the edges of the
Board.

•

Before plugging connectors into the Board, make sure that the power cord has been
unplugged from t he power outle t.

During Inspection:

•

Avoid checking the IC directly with a multimeter; use connectors on the Board.

•

Never create a closed circuit across IC pins with a metal tool.

•

When it is absolutely necessary to touch the ICs and other electrical co mponents on the
Board, be sure to g r ound your body.

During T ransportation/Storage:

•

Use the specified carton whenever moving or storing the PC Drum.

•

The storage temperature is in the range between –20°C and +40°C.

•

In summer, avoi d l eaving the PC Drum in a car for a long time .

Handling:

•

Ensure that the correct PC Drum is use d.

•

Whenev er the P C Drum has be en re mo v ed from t he copi er, store it in its container or pro ­tect it with a Drum Cloth.

•

The PC Drum exhibits greatest light fatigue after being exposed to strong light over an
extended period of time. Never, therefore, expose it to direct sunl i ght.

•

Use care not to contaminate the s u rface of the PC Drum with oil-base solvent, finger­prints, and other foreign matt er.

•

Do not scratc h the surface of the PC Drum.

•

Do not apply chem icals to the surface of the PC Dru m .

•

Do not attempt to w ipe clean the surface of the PC Drum.

If, howev er, the surface is contaminated w i th fingerprints, cle an it using the f ollowing pro ce­dure.

1. Place the PC Drum into one hal f of its container.

1076D001

2. Gently wipe t he res id ual to ner off t he su rf ac e of t he
PC Drum with a dry , Dust-Free Cotton Pad.

A. Rotate the PC D ru m so that the area of it s s urface

on which the line of toner left by the Cleaning
Blade is present is facing straight up. Wipe the sur­face in one continuous movement from the rear
edge of the PC Drum to the front edge and off the
surface of the PC Drum.

B. Rotate the PC Dru m slightly and wipe the newly

expose d surface area w ith a CLEAN fa ce of the
Dust-F ree Cotton Pad. Repeat this procedure until
the entire surface of the PC D rum ha s been thor­oughly cleaned.

✽

At this time , always use a CLEAN face of the dry
Dust-F ree C ott on P a d un ti l no t one r is evident on t he
face of the Pad after wiping.

1076D002

3. Soak a small amount of either ethy l alcohol or iso­propyl al cohol into a clean, unused Dust-Free Cot­ton Pad which has been folded over into quarters.
Now, wipe the surface of the PC Drum in one con­tinuous movement from i ts rear edge to its front
edge and off it s surface one to two times.

✽

Never move the Pad back and forth.

1076D003

4. Using the SAME face of the Pad, repeat the pro ce­dure explained in the latter half of step 3 until the
entire surface of the PC Drum has b een w i ped.
Always OVERLAP the areas when w iping. Two
complete turns of the PC Drum would be appropri­ate for cleaning.

NOTES

•

The Organic P hotoconductor Drum is softer than CdS and Seleni um D ru ms and is there­fore susceptible to scratches.

•

Even when the PC Drum is only loca lly dirtied, wipe the ent ire surface.

•

Do not e xpose the PC Drum to direct sunligh t. Clean it as quickl y as possible even un der
interior illumination.

•

If dirt remains after cleaning, repeat the entire procedure from the beginning one more
time.

When using the testers, voltmeters, or multimeters which show only the me an value, not
Rms values, carry out the following pr ocedure.

1. Measure the line voltage.

2. Referring to the Mean Value Chart corresponding to each vol tage area, see the figure
under the voltage obtained in step 1.

If the line voltage is 125 V and Rms value is 81 V, for example , the mean value is 54.5 V.
Therefore, it is recommended that the voltage be adjusted so that the mean value is set as
close to 54.5 V as poss i ble.

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 dev eloped image of t he ori ginal is fo rmed.
(For more details, see “6. PC DRUM”.)

2. Drum Charging
The PC Drum Charge Corona U nit is equipped with a Comb Electrode and a Scorotron
Grid to deposit a uni form negative charge across the entire surface of the PC Drum.
(For more details, see “7. DRUM CHARGING”.)

3. Imag e Er as e
Any areas of charge which are not to be developed are neutraliz ed by lighting up LEDs.
(For more details, see “8 . IMAGE ERASE LAMP”.)

4. Exposure
Light from the Exposure Lamp reflect ed 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 char ged in the Developer Mix i ng Chamber is attracted onto the electr o­static latent ima ge c ha ngin g it to a v isi bl e , deve lope d ima ge . A DC neg ative bias v olt ag e is
applied to t he Sle eve/Magn et Rol l er to pr e vent toner from being a ttr ac te d ont o th ose area s
of the PC Drum which correspond to the background areas of the orig inal.
(For more details, see “1 1. DEVELOPMENT”. )

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 res t at take-up. (2nd Drawer: 23 cpm Copier Only)
(For more details, see “13. PAPER T AKE-UP/FEED SECTION”.)

7. Image Transfer
The single-wire I mage Transfer Coro na Unit ap plies a D C neg ati v e coron a emis sion t o 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 Pa per Separator Corona Unit applies an AC corona e m i ssion to the
underside of t he p ape r to neu tr ali z e the pap er. In addition, mechanical pape r sepa ra tio n is
provided by the two PC Drum Paper Separ ator 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 “1 7. 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 “2 2. EXIT UNIT”.)
