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 120-
127V, 1.29KW or more, or 220–240V, 1.27KW or more.
•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
outletbeingusedforthecopier.
•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 underneath the mecha-
nism.
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.
2PRECAUTIONS FOR INSTALLATION

98.04.24
G-11
1174SBG0300A
To ensure that the copier is used in an optimum condition, observe the following precau-
tions.
•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: 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.

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 tobe 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.).
