1 2 3 4 5 6 C7085-90921 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. Chapter 3 Installation and configuration 55
