So I get my cartridges, install them in my printer, they are compatible and detected so far so good ... Except that when making a test print, I see that there is a worry. Regardless, I retried, and there I see on my screen printer "Attention empty cartridges." I open the hood saying "Great, I bought without ink cartridges!" I would have much preferred it actually. The cartridges were filled well, except that they are emptied himself completely IN the printer! Result: ink around the plastic, where the support was placed in the printer and the circuits.
For what reason? I compared afterwards an original cartridge Brother and one of those * beep *, and I've realized that where there is a small valve system for the ink to get out into the nozzle but not all alone, these fake cartridges there is a vulgar piece of tape !!! So when this piece of plastic is pierced through the nozzle of the printer, all the ink flows briskly through the hole!
So save 40 thinking, I finally lost 90: I had to buy a new printer, with official cartridges Brother!
