These instructions explain removing the toner cartridge drive arm of an HP Laserjet 4000 and similar models.
1. Remove the Toner Cartridge Drive Arm by using needle-nose pliers to pinch the pin from its hinge on the Top Cover.
Note: Be sure to reconnect the Toner Cartridge Drive Arm when you replace the Top Cover, or the Toner Cartridge will not seat properly.
Removing the Top Cover
2. Remove the four screws holding the Top Cover. Two of the screws are located behind the Rear Output Bin (near the top). The remaining two are on top of the printer beneath the Top Cover.
Releasing Tabs to Lift the Top Cover
3. Squeeze the right-front side of the Top Cover to remove it. It may be necessary to use a small flat-blade screwdriver to release the tab inside the small hole.
4. Holding the Output Assembly in place (located toward the rear of the printer), remove the Top Cover.
