GENERAL PRECAUTIONS REGARDING THE INSTALLATION
AND SERVICE FOR THE COPIER 8070/6570/5570/(***)4580
The installation and service should be done by a qualified service technician.


1. Transportation/Installation
· When transporting/installing the copier, move it by the casters while lifting the stoppers.
The copier is quite heavy and weighs approximately 250 kg (551 lb), therefore pay full attention
when handling it.
· Be sure to use a dedicated outlet with AC 115V or 120V/20A (220V, 230V, 240V/10A) or more for
its power source.
· The copier must be grounded for safety.
Never ground it to a gas pipe or a water pipe.
· Select a suitable place for installation.
Avoid excessive heat, high humidity, dust, vibration and direct sunlight.
· Also provide proper ventilation as the copier emits a slight amount of ozone.
· To insure adequate working space for the copying operation, keep a minimum clearance of
80 cm (32") on the left, 80 cm (32") on the right and 10 cm (4") in the rear.


2. Service of Machines
· Basically, be sure to turn the main switch off and unplug the power cord during service.
· Be sure not to touch high-temperature sections such as the exposure lamp, the fuser unit, the
damp heater and their periphery.
· Be sure not to touch high-voltage sections such as the chargers, the transfer belt and the high-
voltage transformer.
· Be sure not to touch rotating/operating sections such as gears, belts, pulleys, fan, etc.
· When servicing the machines with the main switch turned on, be sure not to touch live sections
and rotating/operating sections. Avoid exposure to laser radiation.
· Use suitable measuring instruments and tools.
· Avoid exposure to laser radiation during servicing.
- Avoid direct exposure to beam.
- Do not insert tools, parts, etc. that are reflective into the path of the laser beam.
- Remove all watches, rings, bracelets, etc. that are reflective.


3. Main Service Parts for Safety
· The breaker, door switch, fuse, thermostat, thermofuse, thermistor, etc. are particularly impor-
tant for safety. Be sure to handle/install them properly.


4. Cautionary Labels
· During servicing, be sure to check the rating plate and the cautionary labels such as "Unplug the
power cord during service", "Hot area", "Laser warning label" etc. to see if there is any dirt on
their surface and whether they are properly stuck to the copier.


(***) Model 4580 is only for NAD, ASD and MJD.
5. Disposition of Consumable Parts/Packing Materials
· Regarding the recovery and disposal of the copier, supplies, consumable parts and packing
materials, it is recommended to follow the relevant local regulations or rules.


6. When parts are disassembled, reassembly is basically the reverse of disassembly unless
otherwise noted in this manual or other related documents. Be careful not to reassemble
small parts such as screws, washers, pins, E-rings, toothed washers in the wrong places.


7. Basically, the machine should not be operated with any parts removed or disassembled.


8. Precautions Against Static Electricity
· The PC board must be stored in an anti-electrostatic bag and handled carefully using a wrist-
band, because the ICs on it may become damaged due to static electricity.
Caution: Before using the wrist band, pull out the power cord plug of the copier and make
sure that there is no uninsulated charged objects in the vicinity.




Caution : Dispose of used RAM-IC's (including lithium battery)
according to the manufacturer's instructions.
Vorsicht : Entsorgung des gebrauchten RAM-IC's (inklusive
der Lithium Batterie) nach Angaben des Herstellers.

Addition to the explanation
(1) When a paper feeding error occurs:
: Error has occurred in the unit Disabled
: No error has occurred in the unit Enabled
: To operate continuously, error code ([C]+[8]) is not displayed.
(2) During C11 and C12 error codes
* If the mode which Duplexer is used is selected as "single-sided duplex" or "two-sided duplex",
the "install the Duplexer" message is displayed and printing is not possible.
* If the mode other than the above (the Duplexer is not used) is selected, the operation can be
normally accepted.
(3) During C15, 16, 17 error codes
* If a cassette in which an error has occurred is selected:
The "Add Paper" message is displayed even if the sheet is set, and copying can be performed
when another paper cassette is selected.
* If a cassette other than the above is selected, the operation can be normally accepted.

1.2 Self-Diagnostic Modes
This copier is a multi-function copier (net work printer, DSS). So, compared with conventional copiers:
1) It has more setting items in the self-diagnostic mode.
2) Setting items are related to each other.
For this reason, if normal operations are continued on the control panel (by [0] + [9] or [C] keys) when
adjustments are completed, operation trouble (e.g. machine lock) may occur due to the internal structure
of the program.
So, when the self-diagnostic mode in adjustments after unpacking, servicing or preventative mainte-
nance, first turn the power OFF before handing the copier over to the user.
