[5] UNPACKING AND INSTALLATION
1. A word on copier installation
Improper installation may damage the copier. Please note the follow-
ing during initial installation and whenever the copier is moved.
1. Be sure to use a correctly rated power supply and to ground the
copier.
•For this copier’s power supply requirements, see the name
plate located on the back of the unit.
2. Do not plug the copier into an outlet used by other appliances.
3. Do not install your copier in areas that are:
•damp, humid, or very dusty;
•exposed to direct sunlight;
•poorly ventilated;
•subject to extreme temperature or humidity changes, e.g., near
an air conditioner or heater.
4. Place the copier on a firm, level surface.
2. Cautions
1. Do not expose the photoconductive drum to direct sunlight, and
do not touch the photoconductive drum. Scratches or smudges on
the drum will cause dirty copies.
2. The fusing area is hot. Exercise care in this area.
Never use the oils and greases which are not listed in this
material.
3. Installing procedure
• Unpacking
• Set up
1. Remove the copier from the bag.
2. Remove all pieces of tape from the copier and remove the cor-
rugated cardboard from under the exit tray.
NOTE: Do not place any objects under the exit tray. If there is
something under the exit tray and the exit tray is not
fully opened during copying, a paper misfeed or im-
proper fusing may occur.
3. Open the document cover, unfold the bypass tray, and remove
all pieces of protective packing material.

4. Remove the two screws from the right and left sides of the
copier by inserting a coin or a suitable object into the slot of the
screws.
NOTE: If the screws are not removed, the copier will malfunc-
tion.
5. Press the release lever to open the copier.
6. Remove the TD (Toner/Developer) cartridge from the bag.
NOTE: TD cartridges are sold separately in some areas.
7. Shake the TD cartridge horizontally four or five times.
8. Remove the cover from the TD cartridge.
9. Slide the TD cartridge in until it locks in place.
10. Gently push down the upper half of the copier to close it.
•To do this, place both your hands on the middle of the right-
hand side of the document cover.
11. Pull out the paper tray, remove the pressure plate lock, load
copy paper into the tray, and push the paper tray firmly back into
the copier.
•If the pressure plate lock is not removed, paper will misfeed.
12. Plug the power cord into the copier and then plug the other end
into the nearest outlet.

2. Image forming process steps
Image forming:
A charge is applied to the drum surface by the main corona, and the
image of the original is exposed by the copy lamp. The charge in a
light exposed image area is dissipated according to the degree of
light intensity.Toner is attracted to the charge areas on the drum and
the toner forms a visible image on the drum surface.
Step-1: Optical discharge
Residual charge on the drum surface is removed.
Step-2: Charge
Even negative charge is given to the drum surface.
Step-3: Exposure
Latent image is formed on the drum.
Step-4: Developing
Latent image formed on the drum is then developed into a
visible image with toner.
Step-5: Transfer
The visible image (toner image) on the drum is transferred
onto the copy paper.
Step-6: Cleaning
Residual toner on the drum surface is collected by the clean-
ing blade.
Step-7: Optical discharge
Residual charge on the drum surface is removed.
3. Description of process
Step-1: Optical discharge (by the discharge lamp)
Prior to charge, light from the discharge lamp is projected over the
drum to reduce electrical resistance of the OPC layer and remove
any residual charge to evenly neutralize the drum surface. As the
electrical resistance is decreased, the positive charge in the
aluminium layer moves to neutralize the negative charge present in
the OPC layer.
Step-2: Charge
A uniform negative charge is applied over the OPC drum surface by
the main corona unit.
Step-3: Exposure (Copy lamp, mirror, lens)
The original image is projected through the mirror and the lens to the
OPC drum by the copy lamp.
In the area where light is projected (light section of the original), the
resistance in the OPC layer reduces to discharge negative charges,
resulting in an electrostatic latent image on the drum surface.
Step-4: Developing (–150V DC bias)
The electrostatic latent image in the drum surface is converted into a
visible image by the toner. A bias potential of –150V is applied to the
carrier (MG roller) in this two component magnetic brush developing
method, and the toner is charged positive through friction with the
carrier.

Toner is not attracted to the non-image areas on the drum because
of the developing bias. Thus, if the developing bias were to fail, the
residual charge would attract the toner so that a background would
appear in the non-image areas of the copy.
Step-5: Transfer
The visible image on the drum surface is transferred onto the copy
paper by applying a negative charge from the transfer corona to the
back of the copy paper.
As the transfer effect is 70 to 80%, 20 to 30% of the image remains
on the drum (residual toner) even after the transfer.
Step-6: Cleaning
Toner remaining on the drum is collected by the cleaner blade and
stored in the toner collecting container.
Step-7: Discharge
(same as Step-1)
Step-8:
The transferred image is fixed permanently on the copy paper by the
action of the fuser unit through a combination of heat and pressure,
the toner is fused into the copy paper.
4. Transition of OPC drum surface potential
5. OPC drum membrane decrease correction
The sensitivity falls due to the OPC drum membrane decrease. To
correct this, the copy lamp light quantity is adjusted, preventing
against deterioration in copy quantity.

For setting, use Sim 26-11.

4For every 3,000 copies, the copy lamp voltage is
