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
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.
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.
iv Phaser 7300 Color Printer Service Manual
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).

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)
■ Two 550-Sheet Feeder
■ One 1650-Sheet High-Capacity Feeder (LTD)
■ One 550-Sheet Feeder and one 1650-Sheet High-Capacity Feeder
