The HP 103AD Dual Pack Black Original Neverstop Laser Toner Reload Kit (part W1103AD) contains two toner reload kits for HP Neverstop Laser printers. Unlike a conventional laser printer, the Neverstop range has a built-in high-capacity toner tank: instead of swapping a cartridge, the user inserts a reload kit into the port on top of the printer the toner is transferred into the tank, and the empty kit is then removed. HP rates each kit at 2,500 pages, so this dual pack provides around 5,000 pages of black-and-white printing. It is compatible with the HP Neverstop Laser 1000 printer series and the HP Neverstop Laser MFP 1200 series. HP positions it as clean, easy-to-use, cartridge-free laser printing at a very low cost per page, suited to small offices, schools and home offices with steady monochrome volumes. The box contains two toner reload kits, a recycling guide, a setup guide and a warranty flyer.
