[Handling of Lithium Battery]
- Never fail to follow the following instructions when you discard the used
lithium battery.
1. Never let the battery short-circuited.
If the (+) and (-) terminals contact each other or metal materials, the battery will
be short-circuited. If the batteries are collected and stored inorderly or one upon
another, the above-mentioned case will occur.
- DANGER -
If the battery is short-circuited, it will heat up and may in some cases explode into
fire.
2. Never heat up the battery.
- DANGER -
If you heat the battery up to more than 100 degrees Celsius or put it into the fire,
it may burn dangerously or explode.
3. Never disassemble the battery or press it into deformation.
- DANGER -
If you disassemble the battery, the gas pouring out of the inside may hurt your
throat or the negative lithium may heat up into fire.
If the battery is pressed into deformation, the liquid inside may leak out of the
sealed part or the battery may be short-circuited inside an explode.
4. Never fail to keep the battery out of reach of children.
If you put the battery within reach of children, they may swallow it down.
Should they swallow the battery, immediately consult the doctor.
[Replacement of the Lithium Battery]
1. The lithium battery must be replaced by a trained and authorized service
technician.
2. The battery must be replaced only with the same or equivalent type
recommended by the manufacturer.
3. Discard used batteries according to the manufacturer’s instructions.

!! WARNING !!
Important Safety Precautions
1. Always disconnect electrical supply before placing hands in the
machine.
I. To avoid injuries:
Be sure to disconnect the electrical power before disassembling, assembling, or when
making adjustments on the machine.
II. Protection of the machine:
Make sure to turn OFF the power to the machine before plugging or unplugging the
electrical connectors, or when connecting a Meter.
2. WARNING:
The back light tube of LCD of the Control Panel on this Model contains mercury
which must be recycled or disposed of as hazardous waste.
3. Always connect electrical connectors firmly.
I. To avoid electrical failure:
The connectors must be connected firmly together and onto the PCBs.
Press on the ends of the connectors and then on the middle to ensure a firm fit.
II. Protection of the electrical components:
The electrical components may be damaged due to short circuits caused by a loose
connector.

1. Work Precautions
When conducting maintenance work, be careful to avoid injury caused by springs or the sharp
edges of sheet metal.
Inspection
If you discover any defects or problems during an inspection, fix the problems or if necessary take steps
such as replacing a part.
Removal
Check the problem area. At the same time, examine the cause of the problem and determine whether
the part needs to be removed or disassembled. Next proceed according to the procedures presented in
the Technical Manual. In cases where, for example, it is necessary to disassemble areas with large
numbers of parts, parts which are similar to each other, or parts which are the same on the left and right,
sort the parts so that you do not mix them up during reassembly.
(1) Carefully sort the removed parts.
(2) Distinguish between parts which are being replaced and those which will be reused.
(3) When replacing screws, etc., be sure to use the specified sizes.
Assembly and Installation
Unless specified otherwise, perform the removal procedures in
reverse during assembly and installation. In cases where
protrusions or holes are provided to assist in positioning parts,
use them for accurate positioning and securing.
(Protrusions and holes for positioning parts Half pierced
section)
Tools
Using tools other than those specified can lead to injury or
damage screws and parts. Have all the tools necessary for the
work available.

Sensor types
• Photoelectric sensors may be broadly divided into
the following four types: interrupt types (U-
shaped), actuator types, reflective types, and
transmittive types.
• Magnetic sensors use Hall ICs, which react to the
magnetic force in magnets.
• Always turn off the power before plugging or
unplugging sensor connectors.

Electrical system work
• After removing wire bundles, fasten them with wire
bundle bands (bar lock ties) so that they will not
sag.
• When installing parts, be careful to avoid pinching
or damaging the wire bundles.
• If a fuse blows, always replace it with one with the
specified capacity.
• Using a fuse with a larger capacity can not only
damage parts, but may cause fires.
• Be careful not to drop image scanners, thermal
print heads, and other sensors as they can be
easily damaged.

With an N.O. connection, an internal contact is
connected when the switch actuator is pressed.
With an N.C. connection, an internal contact is
disconnected when the switch actuator is pressed.
Note
The machine is comprised of many gears. When inspecting or replacing parts, apply grease to the
gears. If they are not properly greased, the gears may make abnormal sounds, and malfunctions or
mechanical problems may occur.

master disposal box.
Master-making operation
The original is scanned by the
image sensor, and the image is
transferred onto a master by the
thermal print head.
Master loading operation
The produced master is wound
around the print drum and cut.
The proof-print is printed.
Printing operation
Paper is fed from the paper-feed tray one sheet
at a time for printing. The printed paper is ejected
out onto the paper-receiving tray.
2. Operation Outline

RISO Inc. Technical Communications us.riso.com
[ 2 - 4 ]
CHAPTER 2: MACHINE SUMMARY
(1) When the print drum rotates, the scraper roller and
pickup roller also turn to feed paper. The stripper pad
allows only one sheet to pass through to the second
paper-feed area.
(2) The paper sent from the first paper-feed area contacts
the timing roller and guide roller, and stops temporarily.
This causes slight buckling of the paper.
(3) The timing roller and guide roller start rotating, feeding
paper to the pressure section. (This operation is
referred to as the “second paper-feed”. To prevent
tension from being placed on the end of the paper, the
scraper roller and pickup roller are free to spin.)
(4) When the paper is fed further in from the second paper-
feed area, the pressure roller rises to clamp the paper
between the drum and pressure roller to start the
printing operation.
(5) The printed paper is removed from the print drum by
the separator and separation fan. When the pressure
roller rises, the guide roller also moves up to prevent
tension from being placed on the tailing end of the
paper.
(6) Then, the suction fan sucks in the air to keep the paper
firmly on the transfer belts while the paper is carried to
the paper-receiving tray.
(7) The next sheet of paper is sent to the first paper-feed
area, and the guide roller lowers.
