Va rious symbols and pictures are used in this manual and on the stickers affixed to the machine. These symbols and
pictures provide warnings and instructions to prevent danger to you or other personnel, and to prevent damage to office
property. The meanings of these symbols and pictures are explained below.
WARNING
Indicates a high degree of potential danger. If the warning is ignored, death or serious
injury may result.
CAUTION
Indicates a medium degree of potential danger. If the caution is ignored, medium injury or
damage to property may result.
[Examples of Pictorial Symbols]
A circle with a line through it indicates a prohibited action. The particular act prohibited is indicated by a picture inside the circle. (In the example shown here, the prohibited
act is disassembly.)
A black disc indicates an instruction, or sometimes a prohibited action. The instruction
itself is indicated by pictorial symbols drawn in white on the disc. (In the example shown
here, the instruction is “Remove the plug from the outlet.”)
• These are particularly important safety points and should always be observed.
WARNING
If the machine is used after foreign matter (metal fragments, water, or liquid) has entered the
machine, this may result in fire or electric shock.
•Turn the main unit’s power switch OFF, and then remove the power plug from the outlet. Contact
the sales distributor.
If the machine is used after heat, smoke, strange smell, or other abnormality is detected, this may
result in fire or electric shock.
•Turn the main unit’s power switch OFF, and then remove the power plug from the outlet. Contact
the sales distributor.
Use only the power cord that is provided among the accessories.

How Platemaking and Printing is Performed
The machine performs two processes: platemaking and printing.
Platemaking
In the “platemaking” process, the old master on the drum is removed while the thermal head creates the
scanned image on the new master and transfers it onto the drum.
Printing
In the “printing” process, paper separated from the stack by the feeder roller and paper separator unit is
pressed against the drum unit by the press roller. There are small holes over only the image area of the master
that is attached to the drum, and ink that seeps from these holes is transferred to the paper. The paper is then
peeled from the master by the paper stripper finger. The paper is directed onto the paper ejection belt by a fan
unit and discharged from the machine.
