• Condensation on the corona unit may cause corona charge leakage.
• Condensation on the hopper plate and separation pad may cause paper feed troubles.
If condensation has occurred, print several pages or leave the printer for 2 hours to allow it to
reach room temperature.
If the drum unit is unpacked soon after it is moved from a cold room to a warm room,
condensation may occur inside the unit, which may cause incorrect images. Instruct the user

hours.
