Ordering other manuals
The HP LaserJet Quick Reference Parts Guide, volume I, provides support for
newer color and monochrome printers (see the following page for a complete list
of supported printers). It has been created to help the HPLaserJet service
engineer quickly find common printer field replaceable parts.
While this quick reference guide is intended to provide parts information to the
service engineer, it will not replace the service manual for any HPLaserJet
product. For detailed information about the HPLaserJet products described in
this guide, see the user guide or service manual for that product.
Service manuals for HPLaserJet products are available from Hewlett-Packard.
The phone number for the Service Parts Order Desk is:
(800) 227-8164 (U.S. only)
If you are located outside of the U.S., contact your local HP Sales and Service
office.

Determining the printer version
Two versions of the HP color LaserJet 4500 series printer are available. To accurately
perform removal and replacement procedures or determine the correct part for
reordering, you will need to know the version of the printer that is being serviced. To
identify the printer, check the serial number, which is located at the rear of the printer. All
printers have US or JP in the first two positions of the serial number (for example,
USBB123456). Newer versions of the HP color LaserJet 4500 printer will have an “H” or
letter in the third position (for example, USHB123456). If the letter in the third position in
the serial number is “B”, “C”,”D”, or “F”, then you have an older version of the HP color
LaserJet 4500 printer.
The HP color LaserJet 4550 series printer is equivalent to the newer version of the HP
color LaserJet 4500 series printer, unless otherwise noted. The HP color LaserJet 4550
series printer does have some different service parts from the 4500 series.
