Power Sa fety Precau tions
Power Source
For 115 VAC printers, do not apply more than 127 volts RMS between the supply 
conductors or between either supply conductor and ground. For 230 VAC printers, 
do not apply more than 254 volts RMS between the supply conductors or between 
either supply conductor and ground. Use only the specified power cord and 
connector. This manual assumes that the reader is a qualified service technician.
Plug the three-wire power cord (with grounding prong) into a grounded AC outlet 
only. If necessary, contact a licensed el ectrician to install a properly grounded 
outlet. If the product loses its ground co nnection, contact with conductive parts 
may cause an electrical shock. A protec tive ground connection by way of the 
grounding conductor in the power cord is essential for safe operation.
Disconnecting Power
Wa r ni n g
Turning the power Off using the power switch does not completely de-energize 
the printer. Disconnect the power cord  from the printer. Disconnect the power 
cord by pulling the plug, not the cord. 
Disconnect the Power Cord in the following cases:
• if the power cord or plug is frayed or otherwise damaged, 
• if any liquid or foreign material is spilled into the product, 
• if the printer is exposed to any excess moisture, 
• if the printer is dropped or damaged, 
• if you suspect that the product needs servicing or repair, 
• whenever you clean the product.

Electrostatic Discharge Precautions
Some semiconductor components, and the respective sub-assemblies that contain 
them, are vulnerable to damage by Electrostatic Discharge (ESD). These 
components include Integrated Circuits (ICs), Large-Scale Integrated circuits 
(LSIs), field-effect transistors, and other semiconductor chip components. The 
following techniques will reduce the occurrence of component damage caused by 
static electricity.
Be sure the power is Off to the chassis or circuit board, and observe all other safety 
precautions.
• Immediately before handling any semiconductor components assemblies, 
drain the electrostatic charge from your body. This can be accomplished by 
touching an earth ground source or by wearing a wrist strap device connected 
to an earth ground source. Wearing a wrist strap will also prevent 
accumulation of additional bodily static charges. Be sure to remove the wrist 
strap before applying power to the unit under test to avoid potential shock.
• After removing a static sensitive assembly from its anti-static bag, place it on  a grounded conductive surface. If the  anti-static bag is conductive, you may 
ground the bag and use it as a conductive surface.
• Do not use freon-propelled chemicals. These can generate electrical charges  sufficient to damage some devices.
• Do not remove a replacement component or electrical sub-assembly from its  protective package until you are ready to install it. 
• Immediately before removing the protective material from the leads of a  replacement device, touch the protective  material to the chassis or circuit 
assembly into which the device will be installed.
• Minimize body motions when handling unpacked replacement devices.  Motion such as your clothes brushing together, or lifting a foot from a 
carpeted floor can generate enough static electricity to damage an electro-
statically sensitive device.
• Handle IC’s and Erasable Programma ble Read-Only Memories (EPROM’s) 
carefully to avoid bending pins.
• Pay attention to the direction of parts when mounting or inserting them on  Printed Circuit Boards (PCB’s).

Service Safety Summary
General Guidelines
For qualified service personnel only: Refer also to the preceding “Power Safety 
Precautions” on page xi.
Use care when servicing with power:   Dangerous voltages may exist at several 
points in this product. To avoid personal injury, do not touch exposed connections 
and components while power is On. Disco nnect power before removing the covers 
or replacing components.
Do not wear jewelry:   Remove jewelry prior to servicing. Rings, necklaces, and 
other metallic objects could come into contact with dangerous voltages and 
currents.
Ozone:  During normal operation, this machine produces ozone gas. The amount 
of ozone produced does not present a hazard to the operator. However, it is 
advisable that the machine be operated in a well ventilated area.
Warning Labels
Read and obey all posted warning labels. Throughout the printer, warning labels 
are displayed on potentially dangerous components. As you service the printer, 
check to make certain that all warning labels remain in place. 
Safety Interlocks
Make sure all covers are in place and all Interlock switches are functioning correctly 
after you have completed a printer service call. If you bypass an Interlock Switch 
during a service call, use extreme caution when working on or around the printer.
Class 1 Laser Product
The Phaser 3140/3155/3160 is certified to comply with Laser Product 
Performance Standards set by the U.S. De partment of Health and Human Services 
as a Class 1 Laser Product. This means that this product does not emit hazardous 
laser radiation; which is possible only because the laser beam is totally enclosed 
during all modes of customer operation. When servicing the printer or laser unit, 
follow the procedures specified in this manual and there will be no hazards from 
the laser.
Maintenance
Cleaning
Before cleaning this product, unplug the product from the electrical outlet. Always 
use materials specifically designated for this product, the use of other materials 
may result in poor performance and create a hazardous situation. Do not use 
aerosol cleaners; they may be explosive  and flammable under certain conditions.

and local laws, it may be illegal to dispose of the cartridge into the municipal 
waste. Check with the local waste officials for details on recycling options or the 
proper disposal procedures.
Fuses
Wa r ni n g
Do not install a fuse of a different type or rating. Installing the wrong type or 
rating of fuse can cause overheating and a risk of fire.
Part Replacement
Only use genuine Xerox approved spare parts or components to maintain 
compliance with legislation and safety certification.
