Ricoh LW5100en Operating Instructions Manual page 70

4. Appendix
• 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 exhaust vent
behind the control panel during printing. This is water vapour from the paper, not a sign of
malfunction. Steam might cause condensation to form on the machine, but this will not result in
operational problems.
• 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 anti-condensation heater warm the machine's interior to prevent build-
up of humidity and condensation. With the anti-humidity heater turned on, the machine remains
warm even if its power is turned off.
• Be sure to make a note of the registered machine settings in case they are lost due to accident or
malfunction.
• The manufacturer shall not be liable for any loss or damage resulting from a failure of the machine,
loss of settings, or use of the machine.
• The paper roll tray has the anti-humidity function. Even when the main power switch is in the
standby position, the anti-humidity heater is active if it is turned on.
• If you do not use the machine for a long time, remove the paper from the paper roll tray, or the cut
paper tray and place it in its storage bag.
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 m
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.
