The following rules apply throughout this Service Manual:
1. Each chapter contains sections explaining the purpose of specic functions and the
relationship between electrical and mechanical systems with reference to the timing of
operation.
In the diagrams,
accompanies the symbol, the arrow
represents the path of mechanical drive; where a signal name
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 Act
The Center for Devices and Radiological Health of the US Food and Drum Administration put
into force regulations concerning laser products on August 2, 1976. These regulations apply
to laser products manufactured on and after August 1, 1976, and the sale of laser products
not certied under the regulations is banned within the Untied States. The label shown here
indicates compliance with the CDRH regulations, and its attachment is required on all laser
products that are soled in the United States.
F-0-16F-0-16
A different description may be used for a different product.
Handling of Laser System
When servicing the area around the laser assembly, be sure to turn off the main power.
The machine's covers that can reect laser light are identied by means of a warning label
(Figure). If you must detach a cover showing the label, be sure to take extra caution during
the work.
Laser Safety
Laser beam radiation may pose a danger to the human body. A laser scanner mounted on the
machine is sealed with the protection housing and external cover to prevent the laser beam
from leaking to the outside. The laser beam never leaks out of the scanner as far as users
operate the machine normally.
