Four-pack high-yield black cartridges

This four-pack supplies four LD Products compatible cartridges that replace the Brother LC203BK high-yield black model. Each unit delivers an approximate yield of 550 pages at five percent coverage and is intended for owners of Brother MFC-J4320DW, J4420DW, J4620DW, J5520DW, J5620DW or J5720DW printers purchased in the United States or Canada.

Ink formulation and chip monitoring

The cartridges use a dye-based ink formulation and include a smart chip that reports remaining ink levels to the printer. Stored in a cool, dry place they remain usable for up to 36 months, giving consistent output for typical home or small-office document printing.

Bundled value and regional limitation

Buying the four-pack lowers the cost per cartridge compared with single units and keeps spare ink on hand for uninterrupted printing. The only constraint is regional compatibility; the set will not operate in printers sold outside the United States and Canada.

Questions about this item

How do I install the LD Products LC203BK cartridge and what step is often missed?

Remove the protective tape and orange clip, then insert the cartridge until it clicks; the smart chip must make full contact with the printer sensor for ink-level tracking to work.

What maintenance or replacement will the LC203BK cartridges need over time?

Each cartridge yields about 550 pages at 5 % coverage; store unused units in a cool, dry place and use within 36 months of purchase for optimal performance.

What limit appears first during sustained printing with these cartridges?

The 550-page yield per cartridge is the first limit; after that volume the ink is depleted and the smart chip will signal replacement.
