INTRODUCTION
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 indica te “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.

1.2 Outline of the Electr ical Circuitr y
1.2.1 Outline
The major electrical mechanisms of the controller block are controlled by the CPU on the main controller PCB. The CPU, RAM, DIMM, and the ICs and HDD around the CPU have the following functions:
1.2.2 Main Controller PCB
Name Description CPU • Controls the processing of image data from the reader unit.
• Controls the processing of image data to the printer unit.
• Controls the HDD.
• Controls the interface of the following: network, DMA controller, PCI, and ROM/RAM.
RAM • Stores program data and image data temporarily. DIMM-ROM • Stores the system control program.
• Stores the boot program.
T02-102-01
1.2.3 HDD
Item Description HDD • Sores the system software.
• Stores image data for the Box function.
