Turn off the main power switch before unplugging the power cord. See "Turning Off the Main Power", Preparation.
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 an hour. The machine requires this time to adapt to its new environment.
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 at the rear right side of the machine 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 optional anti-condensation heaters.
The anti-humidity heater and the optional anti-condensation heater warm the machine's interior to maintain the proper humidity. These 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 50 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.
AC power switch
If the machine is not used for several days or longer at a time, set the AC power switch inside the left front cover of the main unit to "Stand by". Make sure that the main power switch is turned off and the main power indicator goes out before turning off the AC power switch. Not doing so may damage the hard disk.
The anti-humidity heater and the anti-condensation heater work even after the AC power switch is turned off as long as the power cord is connected.
In normal operation, keep the AC power switch in the "On" position.
When you set the AC power switch to "Stand by", do not immediately set it to "On". After setting the switch to "Stand by", wait one minute or more before setting it to "On".
