1.9 Operation precautions
To ensure the optimum performance of this machine, observe the precautions described below.
Power source
The power source requirements are as follows.
- Voltage fluctuation: Maximum ± 10% (at 220 to 240 V AC)
- Frequency fluctuation: Maximum ± 3 Hz (at 50 Hz)
– Use a power source with as little voltage or frequency fluctuations as possible.
Operating environment
The environmental requirements for correct operation of the machine are as follows.
- Temperature: 10°C (50°F) to 30°C (86°F) with fluctuations of no more than 10°C (18°F) within an hour
- Humidity: 15% to 85% with fluctuations of no more than 20% within an hour
Storage of copies
To store copies, follow the recommendation listed below.
- Copies that are to be kept for a long time should be kept where they are not exposed to light in order
to prevent them from fading.
- Adhesive that contains solvent (e.g., spray glue) may dissolve the toner on copies.
- Color copies have a thicker layer of toner than normal black-and-white copies. Therefore, when a color
copy is folded, the toner at the fold may peel off.
