Installation Requirements and Handling
Installation Requirements and Handling
Temperature and Humidity 
Conditions
Temperature range: 50 °F to 86 °F (10 °C to 30 °C)
Humidity range: 20 % to 80 % RH (no condensation)
Protecting the machine from condensation
To prevent condensation from forming inside the 
machine in the following cases, let the machine adjust 
to the ambient temperature and humidity for at least 
two hours before use.
When the room where the machine is installed is 
heated rapidly
When the machine is moved from a cool or dry 
location to a hot or humid location
If water droplets (condensation) form inside the 
machine, this can result in paper jams or poor print 
quality.
When using an ultrasonic humidifier
When you are using an ultrasonic humidifier, it is 
therefore recommended that you use purified water or 
other water that is free of impurities. If you use tap water 
or well water, impurities in the water will be dispersed 
through the air. This can be trapped inside the machine, 
causing degradation in print quality.
