GENERAL PRECAUTIONS REGARDING THE SERVICE FOR
THIS EQUIPMENT
The installation and service shall be done by a qualified service
technician.
1. Transportation/Installation
- When transporting/installing the equipment, employ two or more persons and be sure to hold the
positions as shown in the figure. The equipment is quite heavy and weighs approximately 55 kg
(121.23 lb.) (including the finisher), therefore pay full attention when handling it.
- Be sure not to hold the movable parts or units (e.g. the control panel, ADU or RADF) when
transporting the equipment.
- Be sure to use a dedicated outlet with AC 110V/15A, 120V/12A, 220-240V/8A for its power
source.
- The equipment must be grounded for safety.
- Select a suitable place for installation. Avoid excessive heat, high humidity, dust, vibration and
direct sunlight.
- To insure adequate working space for the copying operation, keep a minimum clearance of 30
cm (12”) on the left, 30 cm (12”) on the right and 60 cm (24”) on the rear.
- The equipment shall be installed near the socket outlet and shall be accessible.
- Be sure to fix and plug in the power cable securely after the installation so that no one trips over
it.
- If the unpacking place and where the equipment is to be installed differ, perform image quality
adjustment (automatic gamma adjustment) according to the temperature and humidity of the
place of installation and the paper to be used.
- If the equipment has casters, lock them after the installation.

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.
- When the parts are disassembled, reassembly is the reverse of disassembly unless otherwise
noted in this manual or other related documents. Be careful not to install small parts such as
screws, washers, pins, E-rings, star washers, harnesses in the wrong places.
- Basically, the equipment should not be operated with any parts removed or disassembled.
- 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.
- Be sure not to touch high-temperature sections such as the fuser unit and areas around them.
- Be sure not to touch high-voltage sections such as the chargers, transfer belt, developer, high-
voltage transformer, and power supply unit. Especially, the board of these components should
not be touched since the electric charge may remain in the capacitors, etc. on them even after
the power is turned OFF.
- Make sure that the equipment will not operate before touching potentially dangerous places (e.g.
rotating/operating sections such as gears, belts pulleys, and fans).
- Be careful when removing the covers since there might be the parts with very sharp edges
underneath.
- When servicing the equipment with the power turned ON, be sure not to touch live sections and
rotating/operating sections.
- Use designated jigs and tools.
- Use recommended measuring instruments or equivalents.
- 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
- The door switch, fuse, thermostat, thermofuse, thermistor, batteries, IC-RAMs including lithium
batteries, etc. are particularly important for safety. Be sure to handle/install them properly. 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 recommended by
Toshiba TEC Corporation.
Caution: Before using the antistatic wrist strap, unplug the power cable of the equipment and
make sure that there are no charged objects which are not insulated in the vicinity.

4. Cautionary Labels
- During servicing, be sure to check the rating plate and cautionary labels to see if there is any dirt
on their surface and if they are properly stuck to the equipment.
[1] Identification label
5. Disposal of the Equipment, Supplies, Packing Materials, Used Batteries and IC-RAMs
- Regarding the recovery and disposal of the equipment, supplies, packing materials, used
batteries and IC-RAMs including lithium batteries, follow the relevant local regulations or rules.
- Never attempt to incinerate a used transfer belt unit. This could cause an explosion and burn you
since the toner inside would be scattered.
Caution:
Dispose of used batteries and IC-RAMs including lithium batteries according to this manual.
Attention:
Se débarrasser de batteries et IC-RAMs usés y compris les batteries en lithium selon ce manuel.

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 und wiegt ungefähr
55 kg (mit dem Finisher); deshalb wenn Sie es hochheben oder tragen, passen Sie besonders
auf.
- Beim Transportieren des Geräts nicht an den beweglichen Teilen oder Einheiten (z.B. das
Bedienungsfeld, die Duplexeinheit oder die automatische Dokumentenzuführung) halten.
- Eine spezielle Steckdose mit Stromversorgung von AC 110V/15A, 120V/12A, 220-240V/8A als
Stromquelle verwenden.
- Das Gerät ist aus Sicherheitsgründen zu erden.
- Einen geeigneten Standort für die Installation wählen. Standorte mit zuviel Hitze, hoher
Luftfeuchtigkeit, Staub, Vibrieren und direkter Sonneneinstrahlung sind zu vermeiden.
- Um einen optimalen Kopierbetrieb zu gewährleisten, muss ein Abstand von mindestens 30 cm
links, 30 cm rechts und 60 cm dahinter eingehalten werden.
- 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, damit
niemand darüber stolpern kann.
- Falls der Auspackungsstandort und der Installationsstandort des Geräts verschieden sind, die
Bildqualitätsjustierung (automatische Gammajustierung) je nach der Temperatur und
Luftfeuchtigkeit des Installationsstandorts und der Papiersorte, die verwendet wird, durchführen.
- Wenn das Gerät Rollen hat, sind sie nach der Installation zu verriegeln.

2. Allgemeine Sicherheitsmassnahmen in bezug auf die Wartung
- Während der Wartung das Gerät ausschalten und das Netzkabel herausziehen (ausser Wartung,
die bei einem eingeschalteten Gerät, durchgeführt werden muss).
- 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 die Teile auseinandergenommen werden, wenn nicht anders in diesem Handbuch usw
erklärt, ist das Zusammenbauen in umgekehrter Reihenfolge durchzuführen. Aufpassen, dass
kleine Teile wie Schrauben, Dichtungsringe, Bolzen, E-Ringe, Stern-Dichtungsringe,
Kabelbäume nicht an den verkehrten Stellen eingebaut werden.
- 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.
- Auf keinen Fall Hochtemperaturbereiche, wie die Fixiereinheit und die umliegenden Bereiche,
berühren.
- Auf keinen Fall Hochspannungsbereiche, wie die Ladeeinheiten, das Transferband, die
Entwicklereinheit, den Hochspannungstransformator und das Netzgerät, berühren.
Insbesondere sollten die Platinen dieser Komponenten nicht berührt werden, da die
Kondensatoren usw. auch nach dem Ausschalten des Geräts noch elektrisch geladen sein
können.
- Vor dem Berühren potenziell gefährlicher Bereiche (z. B. drehbare oder betriebsrelevante
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
Komponenten befinden können.
- Bei Wartungsarbeiten am eingeschalteten Gerät dürfen keine unter Strom stehenden, drehbaren
oder betriebsrelevanten Bereiche berührt werden.
- Ausschließlich vorgesehene Werkzeuge und Hilfsmittel verwenden.
- Empfohlene oder gleichwertige Messgeräte verwenden.
- Nach Abschluss der Wartungsarbeiten das Gerät in den ursprünglichen Zustand zurück
versetzen und den einwandfreien Betrieb überprüfen.
- Das berührungsempfindliche Bedienungsfeld stets vorsichtig handhaben und keinen Stößen
aussetzen. Wenn die Oberfläche beschädigt wird, kann dies zu Funktionsstörungen führen.
3. Sicherheitsrelevante Wartungsteile
- Der Türschalter, die Sicherung, der Thermostat, die Thermosicherung, der Thermistor, die IC-
RAMs einschließlich der Lithiumakkus usw. sind besonders sicherheitsrelevant. Sie müssen
unbedingt korrekt gehandhabt und installiert werden. Wenn diese Teile kurzgeschlossen und
funktionsunfähig werden, kann dies zu schwerwiegenden Schäden, wie einem Abbrand, führen.
Kurzschlüsse sind zu vermeiden, und es sind ausschließlich Teile zu verwenden, die von der
Toshiba TEC Corporation empfohlen sind.
Vorsicht: Vor Benutzung der Manschette der Betätigung des Armbandes, das Netzkabel des
Gerätes herausziehen und prüfen, dass es in der Nähe keine geladenen
Gegenstände, die nicht isoliert sind, gibt.

4. Warnetiketten
- Im Rahmen der Wartung unbedingt das Leistungsschild und die Etiketten mit Warnhinweisen
überprüfen [z. B. „Unplug the power cable during service“ („Netzkabel vor Beginn der
Wartungsarbeiten abziehen“), „CAUTION. HOT“ („VORSICHT, HEISS“), „CAUTION. HIGH
VOLTAGE“ („VORSICHT, HOCHSPANNUNG“), „CAUTION. LASER BEAM“ („VORSICHT,
LASER“) usw.], um sicherzustellen, dass sie nicht verschmutzt sind und korrekt am Gerät
angebracht sind.
5. Entsorgung des Geräts, der Verbrauchs- und Verpackungsmaterialien, alter Akkus und IC-RAMs
- In Bezug auf die Entsorgung und Wiederverwertung des Geräts, der Verbrauchs- und
Verpackungsmaterialien, alter Akkus und IC-RAMs, einschließlich Lithiumakkus, sind die
einschlägigen nationalen oder regionalen Vorschriften zu befolgen.
- Eine benutzte Transportriemeneinheit darf niemals verbrannt werden. Dies könnte eine
Explosion verursachen und sie brennen, da der Toner innerhalb der Einheit verstreut wird.
