Installation

2. INSTALLATION

2.1 INSTALLATION REQUIREMENTS

2.1.1 OPERATING ENVIRONMENT

1. Put your machine on a flat, stable surface such as a desk that is free of vibration and

shocks.

2. Use the machine in a well-ventilated room; use the machine within the following ranges of

temperature and humidity: temperature between 10°C and 32.5°C (50°F to 90.5°F), and

the relative humidity is maintained between 20% and 80%.

3. The machine is not exposed to direct sunlight, excessive heat, moisture, or dust.

4. Condensation

When the machine is moved from a cold place into a warm room, condensation may occur

inside the machine, causing various problems as listed below.

 Condensation on the optical surfaces such as the scanner window, lenses, the

reflection mirror and the protection glass may cause the print image to be light.

 If the exposure drum is cold, the electrical resistance of the photosensitive layer is

increased, making it impossible to obtain the correct contrast when printing.

 Condensation on the charge unit may cause corona charge leakage.

 Condensation on the plate and separation pad may cause paper feed failures.

If condensation has occurred, leave the machine for at least 2 hours to allow it to reach

room temperature.

If the drum unit is unpacked soon after it is moved from a cold place to a warm room,

condensation may occur inside the unit which may cause incorrect images. Instruct the end

user to allow the unit to come to room temperature before unpacking it. This will take one or

two hours.

2.1.2 POWER SUPPLY

1. The AC input power supply described on the rating plate of the machine should be within

±10% of the rated voltage.

2. The AC input power supply is within the regulated value.

3. The cables and harnesses are connected correctly.

4. The fuses are not blown.
