R CAUTION:

❒ Make sure that the m

m

m

m indicator on the PC controller operation panel is off be-

fore 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 10mm (0.4") margin at the back leading edge. If there is no margin, the ma-
chine 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 colors. In these cases, make a new master.

• Remove the paper from the tray before relocating the machine. If you relocate

the machine leaving the paper on the tray, reset the paper after the relocation.
If the main switch of the machine is turned on without resetting the paper cor-
rectly, the sensor might be broken.

• Unplug the power cord from the wall outlet before you move the machine.
