• 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 m
3
/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.
