Low ink brother DCP-J125

well, cut the small piece of black tape (or you can use black permanent marker) and then cover the sensor of the cartridge, once the device will ask you to reinstall the cartridge and new system will detect as a new cartridge

on the ink cartridge, midway between the two holes that plug into the printer, there's an opening. evidently, the printer senses ink level thru the little piece of plastic.

with printer OFF, take all ink cartridges out. cut small pieces of duct tape, small enough to cover the hole but not pass the catridge edge. use a small screwdriver or tip of a knife blade to work the edges of the tape into the slot, covering the little plastic window.

insert back into printer. worked for me. it's simpler than it sounds.

I taped a very small white piece of paper over the sensor eyes on either side of the cavity where the cartridge fit. I read that coloring in the actual "windows" that are on either side of cartridge also may help so I did that too.

So open the front, remove cartridge, look on the cartridge for a small circle and color them with black marker (or use electrical tape), look where they would have aligned inside the cavity, tape a small piece of white paper over those sensor eyes.

I just did this and it stopped the blinking. Don't know how long but based on my reading, one of these was the trick.

If you remove the empty cartridge, you will see a small window on the egde that plugs into the printer, in the center. This is where the printer optically scans for ink levels. On the empty color cart, you can try covering that raised spline with electrical tape or by coloring it with a black permanent marker. That should fool the sensor into thinking your ink is full.
