Brother TN645XXLY Toner

The Longest Run Between Toner Changes On The L8000 Series The genuine Brother TN645XXLY prints up to 6,500 pages, the highest yellow yield Brother offers for the HL-L8430CDW and MFC-L8900 series, so a hard-working colour laser goes far longer between swaps. This is Brother's own yellow toner for the TN-645 platform, declared under ISO/IEC 19798 so the page yield can be compared directly against any alternative on a like-for-like basis. Each colour sits in its own cartridge, so you replace only the one that has run out and nothing usable gets discarded. The TN-645 range runs from standard (TN-645, up to 3,000 pages black) through high yield (TN-645XL, up to 5,500 pages black) to super high yield (TN-645XXL, up to 7,500 pages black), which lets you match cartridge size to how much the machine actually prints. Brother formulates and mills its toner for its own imaging system, so density holds from the first page to the last and fine text stays sharp instead of filling in. Genuine cartridges also keep the printer's toner-level reporting accurate, which is what lets an office order a replacement before it runs dry rather than after. Using original Brother supplies protects the machine's warranty position. The TN-645 cartridges pair with the DR-645CL drum unit and the BU-635CL belt unit, which are replaced on their own much longer service intervals. Empty cartridges go back through the Brother recycling program run with Planet Ark. Suits these Brother printers HL-L8430CDW MFC-L8930CDW MFC-L8970CDW
