If the cooling fan unit is installed on the finisher, do not turn off the cooling fan unit while the machine is on. The fan in the cooling fan unit stops automatically after printing is complete.
Turn off the main power switch before unplugging the power cord. See Turning On/Off the Power.
If the ambient temperature is 29°C (84.2°F) or higher and the machine has been operating continuously, the internal fan will start operating. The fan makes some noise as it cools the inside of the machine. This noise is normal and the fan is working properly. The message “Internal cooling fan is active.” appears on the screen. Do not turn off the main power switch while the fan is operating.
If the ambient temperature is high, the internal cooling fan operates even if the machine is in standby mode. The fan makes some noise as it cools the machine. This is not a malfunction. Do not turn off the main power switch.
After scanning originals continuously, the exposure glass may become warm - this is not a malfunction.
The area around the vents might feel warm. This is caused by exhaust air and is not a malfunction.
If the machine is moved from a cold to a warm place, condensation may form inside it. After moving the machine, do not use it for at least two hours. The machine requires this time to adapt to its new environment.
When the machine is left in a place where the temperature is low, condensation may develop inside the fusing unit. In order to maintain print quality, if drops of water are found within the fusing unit, wipe them before starting a print job.
Do not turn off the power while the machine is in operation.
Do not open the covers of the machine when it is in operation. If you do, misfeeds might occur.
Do not move or tilt the machine when the power is on.
Do not knock the machine while it is operating (for instance, do not use the machine's surfaces to knock stacks of paper into square).
Depending on the ambient temperature and humidity, steam may come from the vents behind the control panel during printing. This is water vapor from the paper, not a sign of malfunction.
If condensation forms inside the machine as a result of temperature change, the machine may not print properly. To minimize this problem, use the anti-condensation heaters.
The anti-humidity heater and the anti-condensation heater warm the machine's interior to maintain the proper humidity. The heaters keep the machine warm even if the main power switch is turned off.
Ventilation
When you use this machine in a confined space without good ventilation for a long time or print large quantities, you might detect an odd smell.
This might cause the output paper to also have an odd smell.
When you detect an odd smell, regularly ventilate in order to keep the workplace comfortable.
Set up the machine so that it does not directly ventilate towards people.
Ventilation should be more than 30 m3/hr/person.
New machine smell
When a machine is new, it might have a unique smell. This smell will subside in about one week.
When you detect an odd smell, sufficiently ventilate and circulate the air in the room.
