The following rules apply throughout this Service Manual:
1. Each chapter contains sections explaining the purpose of specific functions and the relationship between electrical and
mechanical systems with reference to the timing of operation.
In the diagrams, represents the path of mechanical drive; where a signal name accompanies the symbol, the arrow
indicates the direction of the electric signal.
The expression "turn on the power" means flipping on the power switch, closing the front door, and closing the delivery unit
door, which results in supplying the machine with power.
2. In the digital circuits, '1' is used to indicate that the voltage level of a given signal is "High", while '0' is used to indicate "Low".
(The voltage value, however, differs from circuit to circuit.) In addition, the asterisk (*) as in "DRMD*" indicates that the DRMD
signal goes on when '0'.
In practically all cases, the internal mechanisms of a microprocessor cannot be checked in the field. Therefore, the operations
of the microprocessors used in the machines are not discussed: they are explained in terms of from sensors to the input of
the DC controller PCB and from the output of the DC controller PCB to the loads.
The descriptions in this Service Manual are subject to change without notice for product improvement or other purposes, and
major changes will be communicated in the form of Service Information bulletins.
All service persons are expected to have a good understanding of the contents of this Service Manual and all relevant Service
Information bulletins and be able to identify and isolate faults in the machine.

Laser Safety
Since radiation emitted inside this machine is completely confined with protective housings and external covers, the laser beam
cannot escape from the machine during any phase of normal use by users.
Therefore, this machine is classified as a Class 1 laser product under the international standard IEC60825-1 that is regarded as
safe during normal use.
How to Handle the Laser Scanner Unit
This machine is classified as a Class 1 laser product.
However, the laser scanner unit contains source of Class 3B laser beam and exposure to the beam may cause eye injuries.
Therefore, be sure not to disassemble the laser scanner unit. No adjustment can be made to the laser scanner unit in the machine
in the field.
The label shown in the following figure is affixed on the laser scanner unit.
Dieses Gerät ist der Klasse 1 der Laserprodukte zugeordnet.
Allerdings enthält die Laserscannereinheit eine Laserstrahlquelle der Klasse 3B, die Augenschäden verursachen kann, wenn
man in diesen Strahl blickt.
Deshalb darf die Laserscannereinheit nicht zerlegt werden. An der Laserscannereinheit kann keine Justage vor Ort vorgenommen
werden.
Der in folgendem Bild dargestellte Aufkleber ist auf der Laserscannereinheit angebracht.
Power Supply
• As a general rule, do not use extension cords.
If an extension cord must be used, however, use one for local rated voltage and over, untie the cord binding, and insert the
power plug completely into the extension cord outlet to ensure a firm connection between the power cord and the extension
cord.
CAUTION:
Do not plug multiple cords together to an extension cord. It may cause a fire or electrical shock.
• The socket-outlet shall be installed near the equipment and shall be easily accessible.
Safety Precautions
2

Toner Safety
About Toner
Toner is a nontoxic matter composed of plastic, iron and a trace of pigments.
CAUTION:
Never throw toner in flames to avoid explosion.
Handling Adhered Toner
• Use dry tissue paper to wipe off toner adhered to skin or clothes and wash in water.
• Never use warm water for cleaning up toner to prevent toner particles from being gelated to soak into fibers permanently.
• Toner particles are reactive with vinyl polymers. Avoid contacting these materials.
Notes When Handling a Lithium Battery
Dispose of used batteries according to the instructions.
CAUTION:
Risk of explosion if battery is replaced by an incorrect type.
The following warnings are given to comply with Safety Principles (EN60950-1).
CAUTION:
Wenn mit dem falschen Typ ausgewechselt, besteht Explosionsgefahr.
Gebrauchte Batterien gemäß der Anleitung beseitigen.
Notes Before it Works Serving
• At servicing, be sure to turn OFF the power source according to the specified steps and disconnect the power plug.
• Be sure to disconnect the power plug on a regular basis and remove dust and dirt accumulated around the outlet with dry
cloth.
CAUTION:
Leaving the power plug connected for a long time in an environment having a lot of dust, moisture, or oily smoke will
cause a fire. (Because dust accumulated in the surrounding area will absorb moisture and cause an insulation failure)
Safety Precautions
3

Points to Note at Cleaning
When performing cleaning using organic solvent such as alcohol, be sure to check that the component of solvent is vaporized
completely before assembling.
Notes on Assembly/Disassembly
Follow the items below to assemble/disassemble the device.
1. Disconnect the power plug to avoid any potential dangers during assembling/disassembling works.
2. If not specially instructed, reverse the order of disassembly to reinstall.
3. Ensure to use the right screw type (length, diameter, etc.) at the right position when assembling.
4. To keep electric conduction, binding screws with washers are used to attach the grounding wire and the varistor. Ensure to
use the right screw type when assembling.
5. Unless it is specially needed, do not operate the device with some parts removed.
6. Never remove the paint-locked screws when disassembling.
CAUTION:
