About this machine

The Brother Innov-is NX400Q is a discontinued lightweight sewing and quilting machine. Brother specifically documents an extra-wide quilting table, knee-lifter support and a hard carrying case, positioning the model for quilting classes, travel and handling larger fabric pieces.

The Q suffix is meaningful

Brother describes NX400Q as a quilting model and includes an extra-wide table and knee-lifter setup. Those package details are enough to distinguish NX400Q from NX400, even though the two model names are close and some accessories overlap.

Portability is part of the original design brief

Brother explicitly promoted the NX400Q for quilting classes, trade shows and quilting groups. The hard case and lightweight format support portable use.

Do not invent missing numbers from adjacent NX models

Brother's surviving NX400Q page does not expose the same complete specification table as NX570Q.
