Brother LC-970VALBP Multipack Tintenpatrone Tintenpatrone

Unfortunately unusable as the printer constantly claims the color cartridges are empty although I NEVER print in color! Unfortunately there are no printers for a home office that only print in black! Truly a lucrative business model, especially because my printer refuses to work even if only one color is supposedly empty! I have already opened one of these cartridges and found that it was not completely empty! I recommend that you open a new cartridge and you will find that they are delivered almost empty! If this problem didn't occur in exactly the same way with all suppliers, I would have purchased a different product a long time ago! Yes, the printers cost practically nothing but the big money is generated with empty printer cartridges! Criminal!!! I will now be contacting the Swiss Consumer Protection Foundation, our price watchdog, the Beobachter, the K-Tipp and SRF's Kassensturz department about this!
