How to Remove a 2840 Toner Cartridge Without Power On
- 1). Press the scanner release button located on the right-hand side of the HP LaserJet 2840. Open the top cover of the printer.
- 2). Unbend a large paper clip, and insert it into the slot on the right-hand side. Look for the blue arrow with the white guide next to it, and insert the paper clip in the guide. This will unlock the carousel clutch.
- 3). Rotate the toner cartridge carousel until the color you need is visible, then lift the used cartridge out of the machine. Remove the new toner cartridge from the box, and pull the orange tab out to release the toner.
- 4). Squeeze the blue tabs on the new toner cartridge, and carefully lower the cartridge into the carousel. Make sure the toner fits firmly in place, then close the printer and the scanner cover.
