2. Use only the p ower cable supplied with the machine. Use of an incorrectly specified cable
could cause the cable to overheat and potentially cause a fire.
3. Do not overload the power socket, this could lead to overheating of the cables inside the wall
and could lead to a fire.
4. Do not allow water or other liquids to spill into the machine, this can cause electric sho ck. Do
not allow paper clip s, pins or other fo reign object s to fall into the machine these cou ld cause a
short circuit leading to an electric shock or fire hazard.
5. Never touch the plugs on either end of the power cable with wet hands, this can cause electric shock. When servicing the machine, remove the power plug from the wall socket.
6. Use caution when inserting or removing the power connector. The power connector must be
inserted completely oth erwise a poor contact cou ld cause overheati ng and possibly leadin g to
a fire. When removing the power connector grip it firmly and pull.
7. Take care of the power cable. Do not allow it to become twis ted, bent sharply round corners
or otherwise damaged. Do not place objects on top of the power cable. If the power cable is
damaged, it could overheat and cause a fire or exposed wires could cause an electric shock.
Replace a damaged power cable immediately, do not reuse or repair the damaged cable.
Some chemicals can corrode the coating on the power cable, weaken the cover or exposing
wires causing fire and shock risks.
8. Ensure that the power sockets and plugs are not cracked or broken in any way. Any such
defects should be repaired immediately. Take care not to cut or damage the power cable or
plugs when moving the machine.
9. Avoid damp or dusty areas, in stall the machine in a clean well vent ilated location. Do not
position the machine near a humidifier. Moisture and dust build up inside the machine can
lead to overheating and cause a fire.
10.Do not position the machine in direct sunlight.
11.Do not insert any metal objects into the machi ne through th e ventila tor fan or othe r part of the
casing, it could m ake co nta ct w i th a h ig h volta ge conductor insi de th e m a chine a nd cause an
electric shock.
Handling Precautions
The following instructions are for your own personal safety, to avoid injury and so as not to damage the machine
1. Ensure th e mac hine is in stal led on a level surface, capable of supporting its weight. Failure to
do so could cause the machine to tip or fall.
iv 04/08 Phaser 3100 MFP
Introduction
2. The machine contains many rollers, gears and fans. Take great care to ensure that you do
not catch your fingers, hair or clothing in any of these rotating devices.
3. Do not place any small metal objects, containers of water, chemicals or other liquids close to
the machine which if spilled could get into the machine and cause damage or a shock or fire
hazard.
4. Do not install the machin e i n ar e as wit h hi gh dust or moisture levels, beside an o pen window
or close to a humidifier or heater. Damage could be caused to the machine in such areas.
5. Do not place candles, burning cigarettes, etc. on the machine, these could cause a fire.
6. The fuser unit works at a high temperature. Use caution when working on the machine. Wait
for the fuser to cool down before disassembly.
Assembly / Dis assembly Precautions
Replace parts carefully, al ways use Xerox parts. Take care to note the exact location of parts and
also cable routing before disman tlin g any p art o f the ma chine . Ensur e all part s and ca bles are replaced correc tly.
Please carry out t he followi ng procedu res befo re disma ntling th e machine or replaci ng any pa rts.
1. Check the contents of the machine memory and make a note of any user settings. These will
be erased if the mainboard is replaced.
2. Ensure that power is disconnected before servicing or replaci ng any electrical parts.
3. Disconnect printer interfa ce cables and power cables.
4. Be sure to remove the print cartridge before you disassemble any parts.
5. Only use approved spa re p arts. E nsure that pa rt nu mber , pro duct na me, a ny volt age , curren t
or temperature rating are correct.
6. When removing or re-fitting any parts do not use excessive f orc e, especially when fitting
screws into plastic.
7. Take care not to drop any small parts into the machine.
8. Handling of the OPC Dr um
- The OPC Drum can be ir reparably damaged if it exposed to light.
Take care not to expose the OPC Drum either to direct sunlight or to fluorescent or incandes-
cent room lighting. Exposure for as little as 5 minutes can damage the surface’s photoconductive properties and will result in print quality degrad ation. Take extra care when servicing
the machine. Re move the OPC Dru m an d store it in a bla ck bag or other li g htproof conta iner.
Take care when working with the covers (especially the top cover) open as light is admitted to
the OPC area and can damage the OPC Drum.
- Take care not to scratch the green surface of OPC Drum Unit.
If the green surface of the Drum Cartridge is scratched or touched the print quality will be
compromised.
ESD Precautions
Certain semiconducto r devices can be easily damaged by static electric ity. Such components a re
commonly called “Electrostatically Sensitive (ES) Devices”, or ESDs. Examples of typical ESDs
are: integrated circuits, some field effe ct transistors, and semicond uctor “chip” components.
Phaser 3100 MFP 04/08 v
Introduction
The techniques outlined below should be followed to help redu ce the incidence of component
damage caused by static electricity.
CAUTION
Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
1. Immediately before handling a semiconductor component or semiconductor-equipped
assembly, drain off any electrostat ic charg e on your body by touching a known ear th ground .
Alternatively, employ a commercially available wrist strap device, which should be removed
for your personal safety reasons prior to applying power to the unit under test.
2. After removing an electrical assembly equipped with ESDs, place the assembly on a conductive surface, such as aluminium or copper foil, or conductive foam, to prevent electrostatic
charge buildup in the vicinity of the assembly.
3. Use only a grounded tip soldering iron to solder or desolder ESDs.
4. Use only an “anti-static” solder removal device. Some solder removal devices not classified
as “anti-static” can generate electrical charges sufficient to damage ESDs.
5. Do not use Freon-prope lled chemi cals. When sprayed, these can genera te electrical charges
sufficient to damage ESDs.
6. Do not remove a replacement ESD from its protective packaging until immediately before
installing it. Most repl ace ment ESDs are packaged with all leads shorted together by conductive foam, aluminium foil, or a comparable conductive material.
7. Immediately before removing t he pro tective shor ting mate rial from the lea ds of a replacem ent
ESD, touch the protect ive material to the chassis or cir cuit assembly into which the de vice will
be installed.
8. Maintain continuous electrical contact between the ESD and the assembly into which it will be
installed, until completely plugged or soldered into the circuit.
9. Minimize bodily motions when h andling unpackaged replacement ESDs. Normal mot ions,
such as the brushing together of clothing fabric and lifting one’s foot from a carpeted floor,
can generate static electric ity sufficient to damage an ESD.
