CONTENTS
(Maintenance tables)

GENERAL
The major differences between the AR-800 and the AR-650 are
described below.
1. Specifications
The major differences between the AR-800 and the AR-650
lie in the copy (print) speed and the maintenance cycle.
(Max. copy (print) speed)
AR-650: 65CPM (PPM)
AR-800: 80CPM (PPM)
The process speed is the same, but the paper feed interval
differs.
(Maintenance cycle and consumable parts replacement cycle)
AR-650: Every 400K
AR-800: Every 440K
2. Hardware
Differences between the AR-800 and the AR-650
1) The PWA-F-LGC PWB differs.
AR-650: PWA-F-LGC-300
AR-800: PWA-F-LGC-304
(Different parts): Connector, EEPROM, FLASH ROM
The above two PWBs are not compatible each other.
2) Front cabinet
3) Model badge
3. Options
The AR-P13 (printer unit) is also revised for either of two
models, the AR-650 and the AR-800.
The differences between the old and new versions are as
follows:
(AR-P13 for AR-650)
Characters printed on the packing case are in black.
Firmware version: 1.43
Software version: (CD-ROM) 1.10
(Printed on the packing case)
(AR-P13 for AR-650/800)
Characters printed on the packing case are in blue.
Firmware version: 1.44
Software version: (CD-ROM) 1.20
(Printed on the packing case)
4. Others
The temperature control in the fusing section differs between
the AR-650 and the AR-800.
Except the above, the AR-800 and the AR-650 are the same.
The service documents are based on the above contents.
A. Service manual
Chapter 1. SPECIFICATIONS, ACCESSERIES, OPTIONS,
SUPPLIES
Comprehensive contents of the AR-800 and the AR-650
(Complete version)
Chapter 14. FUSER UNIT
Since the temperature control of the fusing section on page
14-5 differs between the AR-800 and the AR-650, the
temperature control of the AR-800 is added.
Only the contents of page 14-5 are described.
B. Actual wiring diagram
Since the PWA-F-LGC-304 (for AR-800) is newly employed,
the connector wiring is changed and the actual wiring
diagram is changed. The actual wiring diagram for the AR-
800 is newly prepared.
C. Service Handbook
Though the maintenance cycle and the consumable parts
replacement cycle differ between the AR-800 and the AR-
650, the contents of the Service Handbook are not changed.
Be sure to note the maintenance cycle of both models for
servicing.
AR-650: Every 400K
AR-800: Every 440K
D. Parts Guide
Only the different sections between the AR-650 and the AR-
800 are prepared.
Sections 1, 2, 5, 6, 13, 31, 39, 47, 62, 86, 101, 203, 204
(including the contents of both models, AR-800/AR-650)
For servicing of the AR-800, use these documents as well
as the service document of the AR-650.

1. The Thermistor status counter normally has a value of between 0 and 9.
•At the power on, if the heater is not turned ON and the copier goes into C41 CALL SERVICE, check the
Thermistor status counter to see if it is 2 or more. If it is 2 or more, be sure to check the thermistor and
heater lamp, and after repair, reset the Thermistor status counter (08-code 400) to 0 and then turn ON
the power switch.

2. Relationship between the output voltage and the fusing temperature.
• 200°C corresponds to approx. 2.5V and 0.25 V corresponds to approx. 40°C.
3. Relationship between heat roller surface temperature and fuser lamp operation.
14. FUSER UNIT
4. Temperature control at heat roller ends
During multicopying, the temperature at each end (no paper-contact area) of the heat roller normally tends
to rise higher than the controlled temperature of the paper-contact area. Therefore, the circuit is designed so
that if the temperature in the no paper-contact area rises to 240°C, the second thermistor detects this,
causing the heater to be turned OFF immediately regardless of the temperature in the paper-contact area.

If the counter has a value 10 or greater (11 for example), the BC-RAM or the data in it have been
destroyed by charger leakage, etc. In this case, check the guide bias, high-voltage transformers,
charger wires, etc. for any defects. Also, all the data inside BC-RAM needs to be rechecked.

PERIODICAL MAINTENANCE (AR-800)
Inspection every 440,000 Copies
(1) Preparation
1
Ask the copier operator about the present machine conditions and note them down.
2
Before starting the maintenance work, make and retain a few sample copies for comparison
reference purposes.
3Turn the power switch OFF and disconnect the power cord plug.
(2) The periodic inspection should be conducted in accordance with the Periodic Inspection Check list
shown below.
Perform the inspection by referring to the figures, as well as to the explanation in the Service Manual
when necessary.
(3) After the inspection has been completed, plug in the machine and turn the power switch ON, and
check the general operation of the machine by making a few copies and comparing them to those
made previously.
Inspection and Overhaul every 880,000 Copies
(1) Replace all the consumables.
(2) Check that if there is any damage to the parts in the driving section (gear, pulley, timing belt, etc.). In
principle, replace those parts at this time.
(3) Check to see if there is any damage or peeling of adhered parts (tape, Mylar sheet, etc.). Replace
any affected parts if necessary.
(4) Check that if all the switches and sensors operate properly. Replace them if they are not operating
properly.
(5) Clean the inside of the machine thoroughly.
Note: Before inspecting and overhauling the feed section of the 3-cassette feed unit, remove the
PFP upper aligning unit and PFP feed unit from the copier.
