Determining the printer version
Two versions of the HP Color LaserJet 4500 series printers 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
will have US or JP in the first two positions of the serial number (e.g.,
USBB123456). Newer versions of the HP Color LaserJet 4500 printers
will have an “H” or higher letter in the third position (e.g. 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 4550 series printer is similar to the newer version of the 4500
printer, but does contain some new service parts.
