INTRODUCTION
This Service Manual provides information needed to service the DADF in the field. This Service
Manual consists of the following chapters:
Chapter 1 “General Description” introduces the DADF’s features and specifications, and
shows how to operate it.
Chapter 2 “BasicOperation”introduces theADAF’s mechanicaland electricalsystems; italso
explains the principles used in these systems and the timing at which they are
operated with reference to the ADAF’s electrical circuitry.
Chapter 3 “Mechanical System” explains the ADAF’s mechanical construction and how its
parts may be disassembled/assembled and adjusted.
Chapter 4 “Maintenance and Servicing” provides tables of periodically replaced parts and
consumables/durables and scheduled servicing charts.
Chapter 5 “Troubleshooting” provides tables of maintenance/inspection, standards/
adjustments,andproblem identification(image fault/malfunction).
Appendix contains a general timing chart and general circuit diagrams.
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
Informationbulletins.
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.

IV. OPERATION
A. Original Set Indicator
The Original Set indicator turns on when
an original is placed on the original tray, and
flashes when an original jams.
A4/B5 A3/B4
Figure 1-401
Operation
1) If the original is B5R or larger or is A5 in
feeding length, open the original sub tray.
2) Set the side guide to suit the size of the
original.
Reference:
The side guide lock must be removed if
thewidthof theoriginalis largerthan 297
mm (A4/A3). For details, see 3. “Side
Guide Lock” on p. 3-3.
3) Place the originals with the first page on
top.
4) As needed, set the appropriate copying
mode on the copier.
5) Press the copier’s Copy Start key.
B. Warnings and Actions
If the Original Set indicator flashes while
an original is being fed, suspect a jam and
performthefollowing:
1) Remove the originals from the original
tray.
2) Openthe upper cover,and remove thejam.
Then, open the DADF to reset the
warning. (If any original is on the
copyboard glass, remove it.)
Caution:
If the jam is in the copier, the copier will
run jam recovery mode and will
automatically set the originals. Do not
open the DADF to reset.
3) Set the originals in correct order, and set
the stack in the DADF.

C. Routine Maintenance by the User
Instruct the user to clean the following at least once a week:
1. Copyboard Glass
Wipe it with a cloth moistened with water or alcohol; then, dry-wipe it.
2. Feeding Belt
Wipe it with water or alcohol.
3. Other Parts
Clean all other parts of the DADF (if soiled) using a solution of mild detergent; then, dry-wipe
them to remove any residue.
4. Feeding Belt and Feeding Roller
Execute cleaning mode in the copier’s user mode.
5. Stamp
If markings start to be fuzzy, replace the stamp using tweezers.
Stamp Tweezers

Caution:
Do not touch the stamp face. If your skin has come into contact with its ink, be sure to wash it
withwaterimmediately.

CHAPTER 2 BASIC OPERATION
I. BASIC CONSTRUCTION
A. Outline of the Electrical Circuitry
The machine’s electrical mechanisms are controlled by the DADF controller PCB. A
microprocessor (CPU) is used on the DADF controller PCB, and the microprocessor reads the input
signals from the sensors and the copier and generates signals used to drive DC loads (motors,
solenoids) at such times as programmed in advance.

B. Communication with the Copier
The operation modes selected on the copier are communicated to the machine in an IPC
communication method. Likewise, the operation states of the machine are communicated to the
copier in an IPC communication.
If an error occurs in the IPC communication, the copier’s self diagnosis function turns on to
indicate “E400” or “E712” on its control panel.

II. BASIC OPERATION
A. Outline
The machine uses four motors and one clutch to pick up, feed, and deliver originals.
Thepick-upmotor (M1)servesto pickup originals. Thefeeder motor (M2)serves toreverseand
deliver originals. The belt motor (M3) moves and stops originals to and on the copyboard glass, and
delivers them. The delivery motor (M3) operates to deliver originals to the delivery tray.
The clutch (CL) is used to engage or disengage the drive of the feeder motor (M2) and the belt
motor(M3).
