The following rules apply throughout this Service Manual:
1. Each chapter contains sections explaining the purpose of specic 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 ipping 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 eld. 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.

CDRH Provisions
Food and Drug CDRH (Center for Devices and Radiological Health) under FDA (Food and
Drug Administration) enforced provisions of the section for laser and laser products on August
2, 1976. These provisions are applicable to all laser products manufactured or assembled
after August 1, 1976 and allow only products certied their compliance with the provisions
to market in the US. Each product shall have afxed the applicable label as shown below to
follow the labeling requirements prescribed in CDRH provisions.

to the environment. As long as the device is operated under normal conditions, users are
safely arded from laser leaks.
Handling Laser Scanner Unit
Before providing service works for the laser scanner unit and its peripherals, ensure to turn
off the power of the device.
Any cover with potential dangers of laser beam reection has afxed the caution label at the
position shown in the gure below.

Toner Safety
About Toner
Toner is a nontoxic matter composed of plastic, iron and a trace of pigments.
Never throw toner in ames to avoid explosion.
CAUTION:
Never throw toner in ames to avoid explosion.

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 bers permanently.
Toner particles are reactive with vinyl polymers. Avoid contacting these materials.
Notes When Handling A Battery
CAUTION:
Risk Of Explosion If Battery Is Replaced By An Incorrect Type.
Dispose Of Used Batteries According To The Instructions.
The following warnings are given to comply with Safety Principles (EN60950).

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.
