Installing the toner cartridges—for newer

version HP Color LaserJet 4500 and HP Color

LaserJet 4550 printers

Note

The following instructions are for newer versions of the 4500 series and

4550 series printers (see page 140 to determine which version of the

printer you have). See page 51 for instructions for installing toner

cartridges in older version printers.

1 Locate the toner cartridges packaged in the printer box. The printer

uses four different toner colors and has a different toner cartridge

for each color:

C = black; M = magenta; C = cyan; and Y = yellow.

2 If the printer is not already turned on, turn it on and close all doors

and drawers. After the printer warms up for a few minutes, the

control panel displays:

TONER POSITION

BLACK = MISSING.

3 Push the dark gray release button on the left side of the printer ([1])

and open the printer’s top cover ([2]).

4 The cartridge slot for the black toner cartridge is visible. Lift up the

flap that partially covers the cartridge slot.

5 Remove the black toner cartridge from the bag and locate the

orange tab on the end of the toner cartridge. Pull the tab firmly to

remove the inside sealing tape. (If the tab breaks off, pull on the

tape.) Discard the tape.

6 Position the toner cartridge over the cartridge slot so that the blue

arrow on the toner cartridge points to the blue arrow on the printer.

The arrow on the right (control panel side of the printer) should point

straight down.
