How to pick the right ink cartridge (and avoid common issues)

When selecting ink cartridges for Brother MFC-J870DW, start with the cartridge code. This model uses the LC-121 series in four colours: BK (Black), C (Cyan), M (Magenta) and Y (Yellow). If you print often, a CMYK multipack is usually the most convenient option.

Typical user issues for the Brother MFC-J870DW are usually not “printer faults” but maintenance-related situations, such as:

• streaky prints or missing colours – often caused by partially clogged nozzles; consider a cleaning cycle and, if needed, our cleaning fluid,
• faded black text – commonly solved by replacing the black cartridge (LC-121 BK) and running alignment,
• infrequent printing – ink can dry in the head; regular small prints and periodic cleaning help keep the system in good condition.
