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>(P. 484)
● 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.

● Change the setting of <Rdc. Wrinkles(Humidity)/Streaks>. Setting to <On> may solve the problem.
<Rdc. Wrinkles(Humidity)/Streaks>(P. 481)
● If you set to <On>, the printing speed will be slower.
Is the amount remaining in toner cartridge running low?
● Check how much the amount remaining in toner cartridges is left, and replace the toner cartridges as
necessary.
● Regardless of the displayed toner level, the toner cartridge may have reached the end of its lifetime due to
the machine's environmental conditions and the deteriorated materials in the cartridge. Replace the toner
cartridge.
