Xerox DocuPrint P1202 Service Manual iii Product Safety
Warning
This equipment complies with the
requirements in Part 15 of FCC rules for a
class A computing device. Operation of the
equipment in a residential area may cause
unacceptable interference to radio and TV
reception, requiring the operator to take
whatever steps are necessary to correct the
interference.
Product Safety
Electrostatic Discharge
This caution indicates that there are components
which are sensitive to damage caused by
electrostatic discharge.
Shock Hazard
This symbol indicates the presence of potentially
hazardous voltages.
CLASS 1 LASER PRODUCT
The Xerox DocuPrint P1202 laser printers are
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 is a
class of laser product that does not emit
hazardous laser radiation; this is possible only
because the laser beam is totally enclosed during
all modes of customer operation.
The laser and output of the laser scanner unit
produces a beam that, if looked into, could cause
eye damage. Service procedures must be
followed exactly as written without change.
When servicing the machine or laser module,
follow the procedures specified in the manual and
there will be no hazards from the laser.
Laser (FDA): Any laser label visible to service
must be reproduced in the service manual with
location shown or indicated. Safe working
procedures and clear warnings concerning
precautions to avoid possible exposure must also
be included.
The Laser contained in the DocuPrint P1202
meets the following standard: Laser class 3B,
maximum 5mW, wavelength 780nm.
The following LASER symbol will be displayed at
the start of any procedure where possible
exposure to the laser beam exists.
LUOKAN 1 LASERLAITE
KLASS 1 LASER APPARAT
Each P1202 laser printer has the following laser
warning label on the Laser Assembly.

CAUTION
These components are susceptible
to electrostatic discharge. Observe
all ESD procedures to avoid
damage.

2.1.1 Power Sources and Consumption
The Xerox P1202 printers are available in either a 110 or a 220 volt configuration.
2.1.2 Power On/Off
The Xerox P1202 printers have an on/off power switch located on left rear corner of machine. The
machine is equipped with a grounded power socket. Printer will power down automatically, (default
condition, which can be disabled by the customer), when not used for a period of time (see Power
Saver).
2.1.3 Power Saver
The Power Saver reduces power automatically when the printer does not receive data for a period of
time. Power Saver is a menu selection in the Remote Control Panel (RCP) software which provides the
user with the ability to control, when the printer enters the power saver state. The default value is 30
minutes. In Power Save mode, the power consumption is under 30 watts.

• any condensation
• direct sunlight
• chemicals
• vibration
• dusty or dirty environments.
2.5 Options
MEMORY/DRAM: 4MB on board memory standard.
• With the one available memory expansion slot, memory can expand to include a 4, 8, 16, or 32MB

• The SIMM is a customer supplied item (72 pin, 60ns or 50ns, 32 bit, No Parity, EDO SIMM).
2.5.1 PostScript SIMMs
• PostScript requires a total of 12 MB of printer memory. The P1202 comes with 4 MB standard.
NOTE: The PostScript SIMM is an option. (The customer is required to provide the PostScript SIMM).
2.6 Paper Specifications
Papers that meet the specifications may be fed either through the Multipurpose Paper Feeder, or the
Manual Single Sheet Feeder. If you use thick paper (from the RCP menu) with a weight of more than 90
g/m2(40lb), or envelope, you must insert paper into the Manual Single Sheet Feeder and select Thick
Paper.
The Multipurpose Paper Feeder will hold 100 sheets of 60 - 126 g/m2(16 - 43 lb), or 10 envelopes, 25
labels, 30 transparency films and 25 paper labels.

The Manual Single Sheet Feeder capacity is 1 sheet 60 - 135 g/m2.
2.6.1 Paper Limitations
The following are recommended for optimum performance:
• Adhesive label sheets specifically designed for laser printers.
• Transparencies specifically designed for laser printers
• Envelopes with peel-off adhesive strips or more than one fold-over flap to seal must have
adhesives compatible with the heat and pressure of the printer's fusing process.
• Avoid:
— Paper with embossed lettering, perforations, or rough texture.
— Paper to which color was added after the paper was made.
— Printed forms whose ink is not for laser printing.
Most papers that meet the above specifications may be fed either through the multisheet or the single
sheet paper feeder. Some media meets the specifications but is not ideal for feeding, e.g., paper that is
either highly textured, thicker than normal for its weight, or unusually smooth.
