MFC-J6520DW

Owners of the MFC-J6520DW sit in the ledger three-model group of this platform — for them the refill ladder runs high-yield LC103 (600 pages) plus the super-high tier: LC105 colors (1,200 pages) and the LC109BK black (2,400 pages — genuine only in our source range, so no compatible black is listed for it here). The ledger trio is where this family's black split matters most: its super-high black is the LC109BK, not the LC107BK of the five mid-size models, and the two cannot be swapped. Because no compatible LC109BK exists in our source range, this page lists the LC103 singles and sets plus the LC105 color singles, and marks the LC109BK in the table as information only.

The MFC-J6520DW takes LC103 high-yield ink (600 pages per cartridge, ISO/IEC 24711) and the super-high tier: LC105 colors (1,200 pages each) with the LC109BK black (2,400 pages). The LC105 colors beside it are $11.99 each for up to 1,200 pages — about a cent a page.

Chip, ink and everyday use

Ledger-size printing on the MFC-J6520DW does not change the small care routine behind it. The LC103 singles and sets and the LC105 colors here each carry a new chip in separate slots, so one color changes on its own. Keep the small green contacts clean by handling the housing only, and if a firmware update causes a recognition hiccup, reseat the cartridge firmly and restart the printer. No compatible LC109BK is listed here, so keep spares sealed. Every Clever Supplies cartridge here carries a lifetime warranty with 1-year free returns.
