Its Ink Absorber Box is full. Inside the machine, in the back and hidden under the covers is a large plastic box with thick, felt pads packed in it. Every time the machine cleans its printheads, it squirts ink through all its nozzles, collects the mess, and pumps it into that box. After a few thousand cleaning operations, it decides the box is dangerously full of ink and throws up that Error 46.
Getting to the Ink Absorber Box (part number LP1270001) is fairly complex. I think it's time to ask a tech what he/she charges.

The service manual says it could possibly be a bad Main Board or a power supply problem, but it always turns out to be a broken printhead. If it's under warranty (one year) get to an authorized service center and Brother will cover all the costs except your time and gas. If it's just past warranty, call Brother's customer support and beg. Sometimes they issue work orders for warranty service on machines that are past their warranty.
If it's out of warranty, I'd recommend giving up on it. The parts are expensive, it's time-consuming (expensive), and you can buy a replacement machine pretty cheaply. www.BrotherMall.com lists refurbished, more advanced machines for $90.
