2. PRECAUTIONS FOR INSTALLATION

2-1. Installation Site

To ensure utmost safety and avoid breakdown, the printer should NOT be used in a place:

• Where it will be subjected to extremely high or low temperature or humidity.

• Where it will be subjected to sudden fluctuations in either temperature or humidity.

• Which is exposed to direct sunlight.

• Which is in the direct air stream of an air conditioner, heater, or ventilator.

• Which has poor ventilation or is dusty.

• Which does not have a stable, level floor or where it will receive undue vibration.

• Which is near any kind of heating device.

• Which is near volatile flammables (thinner, gasoline, etc.).

• Where it may be splashed with water and electric leakage is likely to occur.

• Which puts the operator in the direct stream of exhaust from the printer.

• Where ammonia gas might be generated.

2-2. Power Source

• 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 printer.

• Ensure that the printer does not ride on the power cord or communications cable of other electric equipment, and that it does not become wedged into or underneath the mechanism.

• 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 printer itself, ride on the power cord?

Use an outlet with a capacity of 110/120/127 V, or 220-240 V.

G-8

Page 31

3. PRECAUTIONS FOR USE

3-1. To Ensure the Printer is Used in an Optimum Condition

• Never place a heavy object on the printer or subject the printer to shocks.

• Insert the power plug all the way into the outlet.

• Do not attempt to remove any panel or cover that is secured while the printer is in a print cycle.

• Do not turn OFF the printer while it is in a print cycle.

• Provide good ventilation if the printer is to be used for a long time in a narrow room.

• Never use flammable sprays near the printer.

• If the printer becomes inordinately hot or produces abnormal noise, immediately turn it OFF and unplug it.

• Do not turn ON the power switch at the same time that 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 printer.

• Do not place a vase or vessel containing water on the printer.

• 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 printer.

3-2. Operating Environment

The operating environmental requirements of the printer are as follows.

• Temperature: 10 to 30 °C

• Humidity: 15 to 85 %

• Rate of temperature change: 10 °C/h

• Rate of humidity change: 20 % Rh/h

3-3. Power Requirements

The power source voltage requirements are as follows.

• Voltage fluctuation: AC110 V - AC127 V -10 %, +6 % (Copying performance assured)

AC 220 V - AC 240 V ±10 % (Copying performance assured)

AC 110 V - AC 127 V -10 %, +6 % (Paper feeding performance assured) AC 220 V - AC 240 V ±10 % (Paper feeding performance assured)

• Frequency fluctuation: 50/60 Hz ± 3 Hz

G-9

Page 32

4. HANDLING OF THE CONSUMABLES

Before using any consumables, always read the label on its container carefully.

• Paper can easily damp. To prevent absorption of moisture, store paper in a place with little moisture.

• Keep consumables out of the reach of children.

• Do not touch the PC Drum with bare hands.

• The same sized paper is of two kinds, short grain and long grain. Short grain paper should only be fed through the printer crosswise, while long grain paper should only be fed lengthwise. The wrapper of the paper is properly marked.

• If your hands become soiled with toner, wash them with soap and water.

• Do not throw away any used consumables. They are to be collected.

• Do not burn, bury in the ground, or throw into the water any consumables.

• Do not store consumables in a place which:

✽ Is hot and humid. ✽ Is subject to direct sunlight. ✽ Has an open flame nearby.

5. MISCELLANEOUS PRECAUTIONS

Use the following precautions when performing service jobs for a printer that uses a laser.

• When a service job needs to be performed in the laser beam path, such as when working around the Print Head Unit or PC Drum, be sure first to unplug the power cord of the printer from the outlet.

• If the service job requires that the power cord be left plugged in, observe the following precautions:

1. Take off your watch, ring, and any other reflective object and wear laser protective gog-

gles.

2. Keep users away from the job site.

3. Do not bring a highly reflective tool into the laser beam path during the service job.
