Is the machine installed in an envir
onment where the temperature changes
rapidly and drastically?
● When the temperature changes rapidly in the environment where the machine is installed, condensation
occurs, which may cause fading or bleeding in images and text. If <Control Condensation> is set to <On>,
condensation inside the machine will be removed. Condensation removal may be performed automatically
due to temperature change.
<Control Condensation>(P. 482)
● While
condensation removal is being performed, printing may not be performed properly and blank paper
may be output.
● If you set to <On>, you need to keep the machine turned ON to maintain the effect of condensation
