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
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."

1.1 New Function
1.1.1 Overview 0009-6725
Background of Product Development
The audio guide on the control panel has been designed to assist people with no sight or limited sight in keeping with
the provisions of the Disabilities Act.
Care has also been taken so that people in general may take advantage of the function for extra help without feeling
anything out of the ordinary. In this sense, the function is expected to add to the ease of use of the machine for general
and handicapped users alike.
Flow of Voice Generation
The machine’s digital voice consists of discrete signals generated by controller system files stored on its hard disk.
These signals are sent from the controller board to the audio board by way of a PCI bus in appropriate sequence.
When they reach the audio board, the signals are merged so that each segment has a specific duration. The result is
then subjected to digital-to-analog conversion and sent to the speaker after volume control.
Slide Switch (SW1) on the Voice Guidance Board-A1
The slide switch (SW1) on the Voice Guidance Board-A1 is provided as a means of switching frequencies (33 MHz/
66 MHz) to suit the transfer speed of the PCI bus. It is important for the switch setting to suit the transfer speed so
that the voice will be free of interruption. If you inadvertently moved the slide, be sure to put it back to its correct
position. For the iR6570/5570, the frequency must be set to 33 MHz.
1.1.2 Using the Function 0009-6726
Preparing the Machine for Audio Guide Mode
For details, see the instructions on installation. The following is an outline of the work.
1. Make sure that the machine is off, and fit the Voice Guidance Board-A1 into the PCI bus.
(Be sure there is at least 512 MB of memory.)
2. Connect the speaker to Line-Out of the Voice Guidance Board-A1, and turn on the machine.
To check to see if the machine has recognized the presence of the Voice Guidance Board-A1,
Sart service mode (by pressing the User Mode key, the 2 and 8 keys at the same time, and then the User Mode key
once again).
Then, make the following selections: COPIER>DISPLAY>ACC-STS
If the notation ‘Voice Board’ is indicated in PCI1 through PCI3, the machine has recognized the presence of the
board.
