• Whenever you install a new ink cartridge, you should align the ink cartridges for
the best possible print quality. If the printout is grainy, has stray dots, jagged
edges, or the ink is bleeding into another color, you can realign them through
Toolbox or the print driver (Windows), HP Utility (Mac OS), or the Toolbox
software for PDAs (Windows Mobile). For more information, see Align the ink
cartridges.
• Make sure ink cartridges have not been tampered with. Refilling processes and
the use of incompatible inks can disrupt the intricate printing system and result in
reduced print quality and damage to the printer or ink cartridge. HP does not
guarantee or support refilled ink cartridges. For ordering information, see HP
supplies and accessories.
