Safety Notes

3

= Locate the Copier in a Well Ventilated Room =

A negligible amount of ozone is generated during normal operation of this

copier. An unpleasant odor may, however, be created in poorly ventilated

rooms during extensive copier operations. For a comfortable, healthy, and

safe operating environment, it is recommended that the room be well

ventilated.

NOTE

Operating Environment

The operating environmental requirements of the copier are as follows.

Temperature : 10°C to 30°C (50°F to 86°F) with a fluctuation of 10°C (50°F) per hour

Humidity : 15% to 85% with a fluctuation of 20% per hour

Using the Copier Properly

To ensure the optimum performance of the copier, follow the precautions listed

below.

◆

NEVER place a heavy object on the copier or subject the copier to shocks.

◆

NEVER open any Doors, or turn OFF the copier while the copier is making

copies.

◆

NEVER bring any magnetized object or use flammable sprays near the copier.

◆

NEVER place a vase or vessel containing water on the copier.

◆

NEVER drop paper clips, staples, or other small pieces of metal into the copier.

◆

NEVER attempt to remove any Cover that is secured.

◆

ALWAYS insert the Power Plug all the way into the outlet.

◆

ALWAYS make sure that the outlet is visible, clear of the copier or copier

cabinet.

◆

ALWAYS ensure that the copier does not ride on the power cord or

communications cable of other electrical equipment, and it does not get such a

cord or cable wedged into its own mechanism.

◆

NEVER leave a damaged or cracked copier power cord unattended. If you find

any of these conditions, immediately shut down the copier, unplug the power

cord, and call your Technical Representative for appropriate action.

◆

ALWAYS provide good ventilation when making a large number of continuous

copies.
