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.

Check Items when Turning OFF the Main Power
The Paper Deck Unit is not equipped with the "main power switch". The power source is supplied by turning ON "the main power
switch" on the host machine.
Notes Before Servicing
CAUTION:
At servicing, be sure to turn off the power source according to the specified steps and disconnect the power plug.
CAUTION:
Do not turn off the power switch when downloading is under way. Turning off the main power switch while downloading is
under way can disable the machine.
Points to Note at Cleaning
CAUTION:
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.

Overview of the Electrical Circuitry
The operating sequence for the Paper Deck Unit is controlled by the DC controller PCB in the host machine. The DC controller
PCB is equipped with CPU. The electric control for the Paper Deck Unit is controlled by the deck driver PCB. The deck driver
PCB is equipped with EEPROM.
NOTE:
The EEPROM stores the following adjustment value.
• Remaining paper level adjustment value (amount of up/down movement distance of the lifter)
• ID for model discrimination
