Accessories For the D640 Printer
1-4 About Your Printer
Compatibility with LaserJet 4Si/5Si Printer
The HP 5000 D640 is compatible with the HP LaserJet 4Si printer driver. However, because
the D640 provides more functionality than the HP LaserJet 4Si, not all D640 features can be
accessed with the 4Si printer driver. You can use third party products or additional
programming to access additional D640 features.
The HP 5000 D640 is also compatible with the HP LaserJet 5Si printer driver. However, there
are a few limitations when using the LaserJet 5Si printer driver. Please refer to Chapter 6,
"Advanced Topics", for a discussion of LaserJet compatibility.
PCL Level 5e
The D640 printer supports PCL, the print language of HP LaserJet printers and the most
widely installed print language in the world. Support for PCL Level 5e provides powerful
formatting capabilities and compatibility with a wide range of software solutions.
Integral Hard Disk
The D640 features an internal hard disk drive(850 MB or more) factory preloaded with
thousands of fonts and symbol sets. The hard disk can also be used for storing additional fonts,
electronic forms as PCL macros, and company logos.
Energy Star Compliance
To help minimize power consumption, the D640 complies with the Energy Star Program of the
U.S. Environmental Protection Agency.
Note If you have not done so, please refer to the Installation Manual and complete the
installation procedures. These procedures ensure the safe operation of the printer and the best
print quality.
The printer requires regular maintenance, as described later in this manual. Although
maintenance takes only a few minutes weekly, it is very important to the quality of the
printouts and the life of the printer.
Caution Hewlett-Packard recommends the use of Hewlett-Packard labelled consumable
supplies. Hewlett-Packard is not responsible for any failures or print quality issues arising
from the use of other than Hewlett-Packard supplies. Such failures are not covered under
warranty or by any Hewlett-Packard service agreement.
