Model and serial numbers

The model number and serial numbers are listed on identification labels located on the rear of the printer. The model number is alphanumeric, such as C4084A for the HP Color LaserJet 4500. The serial number contains information about the country of origin; the printer version; production code; and the production number of the printer (see Figure 1-2). For information on determining the version of printer you are servicing, see page 146.

Note Two versions of the HP Color LaserJet 4500 series printers are available. Before servicing the printer or ordering parts, you will need to identify which printer version you are servicing. For more information, see page 146.

Power and regulatory information

The identification labels on the rear of the printer also contain power rating and regulatory information as shown in Figure 1-3.

CAUTION Converting the voltage on the printer can damage the printer. Do not use any voltage other than the operating voltage. Any attempt to convert operating voltages will void the product warranty (for example, attempting to change a 110V printer to a 220V printer).

The printer must be kept in a proper location to maintain the performance level that has been set at the factory. In particular, be sure that the environment adheres to the specifications listed in this chapter.

Below are recommendations for the printer location and placement. Make sure the printer has the following:

• a well-ventilated, dust-free area

• a hard, level surface (not more than a 2° angle):

• for the HP Color LaserJet 4500 and 4500 N, the surface must support 51 kg (112 lb)

• for the HP Color LaserJet 4500 DN, the surface must support 77 kg (169 lb)

• a level surface that supports all four corners of the 500-sheet paper feeder

• a constant temperature and humidity. (Do not install near water sources, humidifiers, air conditioners, refrigerators, or other major appliances.)

Make sure to keep the printer:

• away from direct sunlight, dust, open flames, or ammonia fumes

• away from walls or other objects. There must be enough space around the printer for proper access and ventilation. See Figure 1-4 on page 8.

• away from the direct flow of exhaust from air ventilation systems

The printer must have the following amounts of space above and around it.

330 mm/13 in^		550 mm/22 in		355 mm / 14 in
