Power Safety Precautions
Power Source
Disconnecting Power
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 electrician to install a properly
grounded outlet. If the product loses its ground connection, contact with
conductive parts may cause an electrical shock. A protective ground
connection by way of the grounding conductor in the power cord is essential
for safe operation.
Warning
Turning the power Off using the power switch does not completely deenergize the printer. You must also disconnect the power cord from the
printer’s Alternating Current (AC) inlet. 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 ser vi cing or repa ir,
■whenever you clean the product.
Phaser 3600 Printer Service Manualv
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 Programmable 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 and Safety precautions:
Warning Labels
For qualified service personnel only: Refer also to the preceding “Power Safety
Precautions” on page v.
Avoid servicing alone: Do not perform internal service or adjustment of this
product unless another person capable of rendering first aid or resuscitation is
present.
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. Disconnect power before
removing the power supply shield 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.
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 3600 is certified to comply with Laser Product Performance
Standards set by the U.S. Department 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.
Phaser 3600 Printer Service Manualvii
Servicing Electrical Components
Before starting any service procedure, switch the printer power Off and
unplug the power cord from the wall outlet. If you must service the printer with
power applied, be aware of the potential for electrical shock.
Warning
Do not touch any electrical component unless you are instructed to do so by a
service proc edure.
Servicing Mechanical Components
When servicing mechanical components within the printer, manually rotate
the Drive Assemblies, Rollers, and Gears.
Warning
Do not try to manually rotate or manually stop the drive assemblies while any
printer motor is running.
Servicing Fuser Components
Warning
This printer uses heat to fuse the toner image to paper. The Fuser is VERY
HOT. Turn the printer power Off and wait at least 5 minutes for the Fuser to
cool before attempting to service the Fuse r or adjacent compo nen ts.
