The descriptions on this Service Manual are based on the following principles.
1.  Each chapter describes the purpose and the role of each function, the relationship 
between the electrical system and the mechanical system, and the operating timing of 
each part.
 "
" on the drawings indicates mechanical drive transmission. If 
 is used 
together with a signal name, it indicates a flow of electricity.
 
"Power supply" in each chapter indicates that the power switch is turned ON, that the 
front door is closed, that the paper exit door is closed, and that the power is supplied to 
the machine.
2.  In the descriptions of the digital circuits of this machine, “1” is used when the voltage 
level of a signal is high, and “0” is used when it is low. The voltage value, however, 
depends on the circuit.
 
Though a CPU is used in this machine, since the internal operation check of the CPU 
is virtually impossible, the operating descriptions of the CPU are omitted. In addition, 
since the printed board is not repaired on the customer side in principle, the circuit 
descriptions of the printed board are limited to rough descriptions using block diagrams. 
 
Therefore, the circuit descriptions are provided in the following three kinds: 
• 
Descriptions from the sensor to the input section of the circuit board which is 
provided with the control function and the drive function.
• 
Descriptions from the output section of the circuit board which is provided with the 
control function and the drive function.
• 
Descriptions of the block diagram of each function.
 
including the sensors and the input section of the circuit board which is provided with 
the control function and drive function. 
Some descriptions may be changed according to modifications on the products, and the 
information on any change will be informed by Service Information (Technical Information) 
occasionally.
To read this Service Manual and Service Information (Technical Information) issued 
occasionally for understanding the machine fully and correctly is an advisable way for 
obtaining the skills and knowledge to maintain the product performance for a longer time and 
to perform troubleshooting efficiently.
There is a portion currently expressed with the illustration of a conventional model in this 
manual.
