Roger, I think you and I might be the only ones here with the 8450. The printer seems designed to change cartridges with the power on, because mine turns itself on whenever I lift the lid. At that point, the cartridge carrier adjusts its position so you can access the cartridges. Flip up the cartridge cover, gently press down on the front of the cartridge, and it should slip right out. Perhaps you flipped the cartridge cover before the carrier had the chance to adjust its position? At any rate, while I'm more-or-less satisfied with the performance, I doubt the printer is worth the hassle/cost of repair. Good luck.
