Printhead for Brother inkjet models

This Graviton 990A3 printhead replaces the original LK3197001 part in compatible Brother printers. It fits the MFC5890C, MFC5895C, MFC6490C, MFC6690C, DCP6690CW and DCP6890C machines. The component restores printing function when the original head fails or degrades. It is a new replacement part supplied in neutral packaging.

Drop-in fit for listed Brother machines

The printhead installs directly into the carriage of the supported models without adapter kits or firmware changes. It operates at 110V as specified for the original equipment. Replacing the head clears nozzle clogs and banding issues that cleaning cycles cannot fix. The repair returns the printer to service without requiring a new device.

Replaces worn or failed original printheads

This part addresses print-quality loss caused by burnt-out nozzles, electrical faults or dried ink in the original head. It is not for printers outside the listed Brother series or for users needing a complete printer upgrade. The jump is worthwhile when the machine is otherwise sound but the printhead is the sole point of failure.
