2. General Precautions at Service
- Be sure to turn the power OFF and unplug the power cable during service (except for the
service should be done with the power turned ON).
- Unplug the power cable and clean the area around the prongs of the plug and socket outlet
once a year or more. A fire may occur when dust lies on this area.
- Whenthepartsaredisassembled, reassemblyisthereverseofdisassemblyunless
otherwise noted in this manual or other related documents. Be careful not to install small
partssuchasscrews,washers,pins,E-rings,starwashers,harnessesinthewrongplaces.
- Basically,theequipmentshouldnotbeoperatedwithanypartsremovedordisassembled.
- The PC board must be stored in an anti-electrostatic bag and handled carefully using a
antistatic wrist strap since the ICs on it may be damaged due to static electricity.
Caution: Beforeusingtheantistaticwriststrap,unplugthepowercableoftheequipment
and make sure that there are no charged objects which are not insulated in the
vicinity.
- Be sure not to touch high-temperature sections such as the fuser unit and areas around
them.
- Besurenottotouchhigh-voltagesectionssuchasthechargers,transferbelt,developer,
high-voltagetransformer,andpowersupplyunit.Especially,theboardofthesecomponents
shouldnotbetouchedsincetheelectricchargemayremaininthecapacitors,etc.onthem
even after the power is turned OFF.
- Makesurethattheequipmentwillnotoperatebeforetouchingpotentiallydangerousplaces
(e.g.rotating/operatingsectionssuchasgears,beltspulleys,andfans).
- Be careful when removing the covers since there might be the parts with very sharp edges
underneath.
- WhenservicingtheequipmentwiththepowerturnedON,besurenottotouchlivesections
and rotating/operating sections.
- Use designated jigs and tools.
- Userecommendedmeasuringinstrumentsorequivalents.
- Return the equipment to the original state and check the operation when the service is
finished.
- Be very careful to treat the touch panel gently and never hit it. Breaking the surface could
cause malfunctions.
3. Important Service Parts for Safety
- Thedoorswitch,fuse,thermostat,thermistor,batteries,IC-RAMsincludinglithium
batteries,etc.areparticularlyimportantforsafety.Besuretohandle/installthemproperly.
If these parts are short-circuited and their functions become ineffective, they may result
in fatal accidents such as a burnout. Avoid short-circuiting and do not use parts not
recommendedbyOKIDATACorporation.

ALLEGEMEINE SICHERHEITSMASSNAHMEN IN BEZUG AUF DIE WARTUNG
Die Installation und die Wartung sind von einem qualifizierten Service-
Techniker durchzuführen.
1. Transport/Installation
- Das Tragen oder Installieren des Gerätes braucht wenigstens zwei Menschen. Die
angezeigten Stellen sind wie in der Abbildung festzuhalten. Das Gerät ist ziemlich schwer
undwiegtungefähr60kg(mitdemFinisher);deshalbwennSieeshochhebenodertragen,
passen Sie besonders auf.
- Beim Transportieren des Geräts nicht an den beweglichen Teilen oder Einheiten (z.B. das
Bedienungsfeld,dieDuplexeinheitoderdieautomatischeDokumentenzuführung)halten.
- EinespezielleSteckdosemitStromversorgungvonAC110V/15A,120V/12A,220-240V/8A
alsStromquelleverwenden.
- DasGerätistausSicherheitsgründenzuerden.
- Einen geeigneten Standort für die Installation wählen. Standorte mit zuviel Hitze, hoher
Luftfeuchtigkeit,Staub,VibrierenunddirekterSonneneinstrahlungsindzuvermeiden.
- UmeinenoptimalenKopierbetriebzugewährleisten,musseinAbstandvonmindestens20
cmlinks,20cmrechtsund60cmdahintereingehaltenwerden.
- Das Gerät ist in der Nähe der Steckdose zu installieren; diese muss leicht zu erreichen
sein.
- Nach der Installation muss das Netzkabel richtig hineingesteckt und befestigt werden,
damitniemanddarüberstolpernkann.
- Falls der Auspackungsstandort und der Installationsstandort des Geräts verschieden
sind,die Bildqualitätsjustierung (automatische Gammajustierung)je nach derTemperatur
und Luftfeuchtigkeit des Installationsstandorts und der Papiersorte, die verwendet wird,
durchführen.
- WenndasGerätRollenhat,sindsienachderInstallationzuverriegeln.

2.AllgemeineSicherheitsmassnahmeninbezugaufdieWartung
- Während derWartung das Gerät ausschalten und das Netzkabel herausziehen (ausser
Wartung,diebeieinemeingeschaltetenGerät,durchgeführtwerdenmuss).
- Das Netzkabel herausziehen und den Bereich um die Steckerpole und die Steckdose die
Umgebung in der Nähe von den Steckerzacken und der Steckdose wenigstens einmal
im Jahr reinigen. Wenn Staub sich in dieser Gegend ansammelt, kann dies ein Feuer
verursachen.
- Wenn dieTeile auseinandergenommen werden, wenn nicht anders in diesem Handbuch
uswerklärt,istdasZusammenbaueninumgekehrterReihenfolgedurchzuführen.
Aufpassen,dasskleineTeilewie Schrauben,Dichtungsringe,Bolzen,E-Ringe,Stern-
Dichtungsringe,KabelbäumenichtandenverkehrtenStelleneingebautwerden.
- Grundsätzlich darf das Gerät mit enfernten oder auseinandergenommenen Teilen nicht in
Betrieb genommen werden.
- Das PC-Board muss in einer Anti-elektrostatischen Hülle gelagert werden. Nur Mit einer
Manschette bei Betätigung eines Armbandes anfassen, sonst könnte es sein, dass die
integrierten Schaltkreise durch statische Elektrizität beschädigt werden.
Vorsicht:VorBenutzungderManschettederBetätigungdesArmbandes,dasNetzkabel
des Gerätes herausziehen und prüfen, dass es in der Nähe keine geladenen
Gegenstände,dienichtisoliertsind,gibt.

InsbesonderesolltendiePlatinendieserKomponentennichtberührtwerden,dadie
Kondensatorenusw.auchnachdemAusschaltendesGerätsnochelektrischgeladensein
können.
- Vordem Berühren potenziellgefährlicherBereiche(z.B.drehbareoderbetriebsrelevante
Bereiche, wie Zahnräder, Riemen, Riemenscheiben und Lüfter) sicherstellen, dass das
Gerät sich nicht bedienen lässt.
- Beim Entfernen von Abdeckungen vorsichtig vorgehen, da sich darunter scharfkantige
Komponentenbendenkönnen.
- BeiWartungsarbeitenameingeschalteten GerätdürfenkeineunterStrom stehenden,
drehbarenoderbetriebsrelevantenBereicheberührtwerden.
- AusschließlichvorgeseheneWerkzeugeundHilfsmittelverwenden.
- Empfohlene oder gleichwertige Messgeräte verwenden.
- Nach Abschluss derWartungsarbeiten das Gerät in den ursprünglichen Zustand zurück
versetzenunddeneinwandfreienBetriebüberprüfen.
- DasberührungsempfindlicheBedienungsfeldstetsvorsichtighandhabenundkeinen
Stößenaussetzen.WenndieOberächebeschädigtwird,kanndieszuFunktionsstörungen
führen.
3.SicherheitsrelevanteWartungsteile
- DerTürschalter,dieSicherung,derThermostat,derThermistor,dieIC-RAMseinschließlich
der Lithiumakkus usw. sind besonders sicherheitsrelevant. Sie müssen unbedingt korrekt
gehandhabtundinstalliertwerden.WenndieseTeilekurzgeschlossenundfunktionsunfähig
werden,kanndieszuschwerwiegendenSchäden,wieeinemAbbrand,führen.
Kurzschlüssesindzuvermeiden,und essind ausschließlichTeile zuverwenden,dievon
derOKIDATACorporationempfohlensind.

4.Warnetiketten
- ImRahmenderWartungunbedingtdasLeistungsschildunddieEtikettenmit
Warnhinweisen überprüfen [z. B. „Unplug the power cable during service“ („Netzkabel
vor Beginn derWartungsarbeiten abziehen“), „CAUTION. HOT“ („VORSICHT, HEISS“),
„CAUTION.HIGHVOLTAGE“(„VORSICHT, HOCHSPANNUNG“),„CAUTION. LASER
BEAM“(„VORSICHT,LASER“)usw.],umsicherzustellen,dasssienichtverschmutztsind
und korrekt am Gerät angebracht sind.
5.EntsorgungdesGeräts,derVerbrauchs-undVerpackungsmaterialien,alterAkkusundIC-
RAMs
- In Bezug auf die Entsorgung undWiederverwertung des Geräts, derVerbrauchs- und
Verpackungsmaterialien, alter Akkus und IC-RAMs, einschließlich Lithiumakkus, sind die
einschlägigennationalenoderregionalenVorschriftenzubefolgen.
- Eine benutzteTransportriemeneinheit darf niemals verbrannt werden. Dies könnte eine
Explosionverursachenundsiebrennen,daderTonerinnerhalbderEinheitverstreutwird.
Caution:
