Do smudges appear when using the machine in an environment with low humidity?
Set <Low Humidity Mode> to <On>.
<Low Humidity Mode>
<Low Humidity Mode>
If you set to <On>, print density may be lower or uneven when the machine is used in an environment with high humidity.
Is the machine installed in an environment 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>

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 removal.
