Ordering D640 Printer Consumables Ordering D640 Printer Consumables You can order consumables directly from Hewlett-Packard by calling 1-800-538-8787 in the United States and Canada. Customers outside the United States and Canada should contact their local Hewlett-Packard sales office. Please plan for a two to five day delivery in the United States, possibly longer outside the United States. If your printer was purchased from a Hewlett-Packard reseller, you may be able to purchase consumables directly from them. Table 4-1 lists the D640 printer consumables, ordering numbers, kit content descriptions and quantities, along with the length of time you can expect them to last under optimum operating conditions. Use the replacement cycle estimates in Table 4-1 to plan your initial consumable purchases. Because yields may vary widely from the estimates, you should track your actual usage to establish proper replacement schedules for each printer installation. Actual yields depend upon: • Media (paper type, weight, chemical composition, perforations, paper dust, and quality). • Media storage factors such as care and handling, room temperature, and humidity. • Exposure to light (photoconductor drum). • Frequency of cleaning the printer. • Average print job size, daily print volume, and patterns of printing. • Ambient environmental conditions, such as temperature, humidity, and static electricity. • Power-on hours. "Managing Consumables" on page 6-6 describes some of the considerations in using and replacing consumables. 4-2 Ordering and Replacing Consumables
