Power Safety Precautions
Power Source
For 110 VAC printers, do not apply more than 127 volts RMS between the supply
conductors or between either supply conductor and ground. Use only the specified
power cord and connector. For 220 VAC printers, do not apply more than 240 volts
RMS between the supply conductors or between either supply conductor and ground.
Use only the specified power cord. This manual assumes that the reader is a qualified
service technician.
Warning: 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 it’s ground connection, contact with
conductive parts may cause an electrical shock.
Disconnecting Power
Warning: Turning the power off using the On/Off switch does not
completely de-energize the printer. You must also
disconnect the printer power cord from the AC outlet.
Position the power cord so that it is easily accessible during
servicing so that you may power down the printer during
an emergency.
Disconnect the power plug by pulling the plug, not the cord.
■ Disconnect the power plug if the power cord or plug is frayed or otherwise
damaged,
■ Or if any liquid or foreign material is spilled into the case,
■ Or if the printer is exposed to moisture,
■ Or if the printer is dropped or damaged,
■ Or if you suspect that the product needs servicing or repair,
■ Or whenever you clean the product.

v
Electrostatic Discharge (ESD) 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:
Caution: Be sure the power is off and observe all other safety
precautions.
■ Immediately before handling any semiconductor component 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 it’s anti-static bag, place it
on a grounded conductive surface such as aluminum foil. 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 unpackaged 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 EEPROM’s carefully to avoid bending pins.
■ Pay attention to the direction of parts when mounting or inserting them on
Printer Circuit Boards (PCB’s).

Summary.
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.
Power source: This product is intended to operate from a power source that will not
apply more then 250 volts rms for a 220 volt AC outlet or 130 volts rms for a 110 volt
AC outlet between the supply conductors or between either supply conductor and
ground. A protective ground connection by way of the grounding conductor in the
power cord is essential for safe operation.
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 covers and panel are in place and that all interlock switches are all
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.

vii
Servicing Electrical Components
Before starting any service procedure, switch off the printer power 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: Turning the power off using the On/Off switch does not
completely de-energize the printer. You must also
disconnect the printer power cord from the AC outlet.
Position the power cord so that it is easily accessible during
servicing so that you may power down the printer during
an emergency.
Warning: Do not touch any electrical component unless you are
instructed to do so by a service procedure.
Servicing Mechanical components
Manually rotate drive assemblies to inspect sprockets 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 a sheet of
paper. The Fuser Assembly is very hot. Switch off printer
power and wait at least 30 minutes for the Fuser to cool
before you attempt to service the Fuser Assembly or
adjacent components.

Secure Prints, Proof Prints, Saved Prints and PDF
Direct Printing
These features are available only if the printer has a hard drive installed.
Note: These jobs are stored on the printer’s optional hard drive and
remain in the printer even when it is powered off. There is a
limit of 100 jobs on the hard drive, per type. When the printer
reaches the limit, it deletes the oldest job per type
automatically before adding the new one.
■ Secure Print: Print confidential documents. A 4-digit numeric
password-protected job is stored on the printer’s hard drive. The job prints
only after entering the 4-digit number on the printer’s front panel.
■ Proof Print: Prints only one copy of a multiple copy job so the user can
proof the copy. The user assigns a job name to the print job and the first set
is printed immediately for proofing. To print the remaining copies, select
the job name on the printer’s front panel. If the user does not want the
remaining copies the job can be cancelled from the printer’s front panel.
■ Saved Print: Stores jobs on the printer’s hard drive for print on demand.
■ PDF Direct Printing: The printer supports a native PDF image processor.
PDF Direct printing uses the printer’s currently defined imaging settings.
Auto sensing of PDF files are included in the emulation sensing and
switching logic when the PDF option is installed.
Power Saver Mode
To conserve power, the printer switches into Power Saver Mode after being idle for
user-selected amount of time. The printer consumes less than 70 watts of power in
Power Saver Mode. The printer leaves Power Saver Mode or “awakens” upon
receiving data or user interaction at the front panel.
Resolutions: The printer supports the following resolutions:
■ 600 x 600 dpi (Draft/Standard Mode)
■ 600 x 2400 dpi (Enhanced Mode)
The printer also accepts 300 x 300 dpi files from PCL legacy drivers, PCL bit map
fonts, and PCL bit map images, although these are imaged at 600 x 600 dpi.
The printer supports these optional lower tray combinations:
■ One 550-Sheet Feeder (LTA)
