Ink and makeup handling
● When handling ink or makeup, such as replenishment or replacement, take enough care not to
spill ink or makeup.
If you spill any ink or makeup by mistake, wipe it off neatly and promptly with wiping paper or
something similar. Do not close the maintenance cover until you make sure that the portion you
have just wiped is completely dry.
You must pay particular attention when you have spilled ink or makeup inside the printer and it
is not completely dry. This is because vapors of ink or makeup will stay inside the product and
may catch on or cause a fire.
If you find it hard to wipe the printer with the power on, stop it with the maintenance cover open.
Power it down and then wipe it off again.
● If you need to clean the casing of the product with wiping paper soaked with makeup, be sure
to do so when the power is off.
Attempting to clean it with the power on will cause makeup or vapors of makeup to enter the
product, possibly catching on or causing a fire.
When the cleaning is finished, open the maintenance cover and make sure that no makeup has
entered and no vapors remain inside.
● Should you find a leak of ink or makeup inside the product while the product is running or being
maintained, wipe it off promptly with wiping paper or something similar. Then, with the
maintenance cover open, stop the product, power it down, and repair the leak.
Otherwise, contact your nearest local distributor.
Continuing operation with a leak of ink or makeup will cause an anomaly, resulting in abnormal
printing. Ink and makeup are flammable. They may therefore catch on or cause a fire.
● Ink and makeup, their waste solution, used wiping paper and empty containers are flammable.
Make sure that these waste disposals are kept away from a flame or arc.
● When cleaning the product or replenishing ink or makeup, wear protective gloves and safety
goggles to avoid direct skin contact. If the ink or makeup comes into contact with skin, wash
thoroughly with soap and warm or cold water.
● When transferring the ink or makeup to or from a bottle, exercise caution to prevent it from
coming into contact with the product or surrounding articles. If there is any spillage,
immediately wipe it to clean using a cloth moistened with makeup.
