Basic Procedure; Mtbf / Mttr - Brother MFC-P2000 - B/W Laser Printer Service Manual

• Condensation on the corona unit may cause corona charge leakage.
• Condensation on the hopper gate and separation pad may cause paper feed
troubles.
If condensation has occurred, wipe the effected units or parts with a dry cloth 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 to allow the unit to come to room temperature before unpacking it. This will take one
or two hours.
