❒
Make sure that the Data In
m
indicator is off before unplugging the power
cord.
• While printing, do not turn off the main switch.
• While printing, do not unplug the power cord.
• While printing, do not open the door or covers.
• While printing, do not move the machine.
• Open and close all doors and covers carefully.
• When printing onto paper that contains images on the back, make sure there
is a 6 mm (0.24") margin at the back leading edge. If there is no margin, the
machine might wrongly detect that paper is wrapped around the drum and
stop printing.
• When you use envelopes or pasted print paper, the leading edge of the prints
might be damaged.
• Always make a few trial prints to check the image position because the image
position of the trial print might not correspond with that of the original.
• The leading edge of the prints might become stained if the edge touches the
image of prints on the paper delivery tray.
• Print ink on the paper delivery tray might stick to the back side of the next
print.
• Press the
{
Proof
}
key to perform a test print as the image density of the first
few prints might be light.
• When the machine is on and the power source is less than 90% of the specified
amount, printing quality will decrease. Therefore, make sure the supply from
your electrical outlet is at least 90% of the required amount.
• When you make a lot of prints from a small image, ink might ooze out from
the edges of the master, especially in high temperatures and when printing in
two or more colours. In these cases, make a new master.
• Keep the machine away from flammable liquids, gases, and aerosols.
A fire or an electric shock might occur.
• Unplug the power cord from the wall outlet before you move the machine.
While moving the machine, you should take care that the power cord will not
be damaged under the machine.
