If you have one of these HP printers: LaserJet Pro 400 M401dn, LaserJet Pro 400 M401dne, LaserJet Pro 400 M401dw, LaserJet Pro 400 M401n, LaserJet Pro 400 MFP M425dn, LaserJet Pro 400 MFP M425dw then you need to use the CF280X toner cartridge in your printer. We recommend the CF280X because it is a high yield cartridge. The CF280X has a page yield of 6,900 pages.
The CF280A also fits in the LaserJet Pro 400 M401dn, LaserJet Pro 400 M401dne, LaserJet Pro 400 M401dw, LaserJet Pro 400 M401n, LaserJet Pro 400 MFP M425dn, LaserJet Pro 400 MFP M425dw printers, but it is a low yield cartridge with a page yield of 2,700 pages.
Of course, the CF280X cartridge is more expensive than the CF280A, but in the long run, it’s your better deal. Your cost per page will be lower. And since toner is a powder, it has a long shelf life. Even if you don’t print a lot, it won’t dry up or go bad.
