large well ventilated room that has air turnover of more than 30 m3/hr/person.
Environments To Avoid
p Locations exposed to direct sunlight or strong light (more than 1,500 lux.)
p Locations directly exposed to cool air from an air conditioner or heated air
from a heater. (Sudden temperature changes might cause condensation
within the copier.)
p Places where the copier might be subjected to frequent strong vibration.
p Dusty areas.
p Areas with corrosive gases.
p Places higher than 2,000 m (6,500 ft) above sea level.

SPECIAL FEATURES
Some of this copier’s features can be adjusted by your service representative to
suit your application needs. This section gives a brief description of these
features. If you wish to get more information or use the following features,
contact your service representative.
Energy Saver Function
With this function, all input modes are reset and the copier uses less electricity.
If you select this function, the copier can automatically turn the energy saver
function on at the same time the automatic reset is turned on. Also, you can
select one of four levels for the saving ratio. The greater the saving ratio, the
more time the copier will need to return to the ready condition.
Automatic Reset Time
1 minute after the final copy is made, all input modes are reset to default
modes. If a 1 minute reset time is not appropriate, 3 minutes or no automatic
reset can be selected.
Copy Counter UP/DOWN
The copy counter can be set to show the number of copies made (count up) or
the number of copies remaining to be made (count down).
Auto Image Density Priority
Auto Image Density mode is selected when the main switch is turned on, or
after auto reset. However, a service representative can select the Manual
Image Density mode as the standard mode.
Auto Image Density Level
The auto image density level can be made lighter or darker.
Maximum Copy Quantity
The maximum copy quantity can be set from 1 to 99. (99 is the standard
setting.)
Reduction/Enlargement Ratio Priority
With the default setting, the reduction ratios are selected at first when pressing
the Reduce/Enlarge key. (Ex.: A4 version machine: 93% →82% →71% →
141% →121%. See page 12.) You can cancel this setting and give priority to
the enlargement ratios.
Optional Key Counter
To use the key counter, additional service parts are required. Please contact
your service representative.
