Graviton LK3197001 Printhead for Brother A3 MFPs

The Graviton LK3197001 is a new 110V printhead designed for Brother MFC6490, MFC6490CW, MFC5890, MFC6690, MFC6890 and MFC5895CW multifunction printers. It restores printing capability on these A3-format office machines when the original head fails or reaches end of life. Installation returns the device to service without requiring a full unit replacement.

Thermal and power behaviour in daily use

Operating at the specified 110V, the printhead draws power only during active printing cycles and remains idle between jobs. Normal office workloads keep the component within its designed thermal envelope without additional cooling measures. Acoustic output is limited to the mechanical actuation of the print mechanism itself.

Replaces a worn or failed Brother printhead

This part directly substitutes the original LK3197001 990 A3 head used across the listed Brother models. The upgrade is justified when print quality degrades due to nozzle clogging or electrical failure that cleaning cycles cannot resolve. It is not suitable for printers outside the named MFC series or for voltage environments other than 110V.

Questions about this item

How is the 110V LK3197001 printhead installed in a Brother MFC6490 and what step do people get wrong?

Power off the MFC6490, open the top cover, release the carriage latch, remove the old head, insert the new LK3197001 unit until it clicks, close the latch, shut the cover and run the alignment routine; the step most often missed is the post-install alignment.

What maintenance will the LK3197001 printhead need later?

The head itself is not user-serviceable; plan to run the built-in cleaning cycle when print quality drops and replace the printhead again when nozzles no longer recover after deep cleaning.

What limit appears first on the LK3197001 during sustained printing on a Brother MFC6890?

Continuous high-volume output will hit the thermal throttle of the 110V head first, forcing the MFC6890 to pause and cool before resuming.
