Setup, Compatibility & Care
To install, power off the printer, open the front toner door, and remove the empty cartridge by pulling the handle straight out. Gently shake the new Alpa-Cartridge side-to-side to distribute the toner evenly before removing the protective shipping clips and orange safety tab. Insert the cartridge firmly until it clicks into place and close the printer door.
Compatibility is strictly limited to the HP Laserjet 4200, 4250, 4300, and 4350 series. To maintain optimal performance, keep unused cartridges in their original sealed packaging in a cool, dark, and dry environment. Avoid touching the green drum roller on the underside of the cartridge, as oils from skin can cause print defects.
