How to use

Remove the used cartridge according to your printer’s user manual, then unpack the new Brother LC-421BK cartridge and remove any protective seals. Insert the cartridge into the correct slot until it clicks into place, close the printer cover, and allow the printer to perform any automatic initialization or alignment. For best results, run a nozzle check and print a test page to confirm proper installation and print quality.

Recommendations

Store unused cartridges in a cool, dry place and keep them in their original packaging until installation. Use the cartridge regularly or run occasional head-cleaning and nozzle-check procedures to maintain print quality. Replace the cartridge once print density or text clarity declines to ensure consistent black output.
