THERE MAY BE MINUTE PARTICLES OF DUST GOT STUCK ON THE CIRCUIT OF YOUR PRINTER IN THE CARRIAGE WHERE YOUR BLACK CARTRIDGE IS FIXED REMOVE YOUR BLACK CARTRIDGE FROM THE PRINTER AND GENTLY CLEAN THE CIRCUITS OF BOTH YOUR PRINTER AND CARTRIDGE WITH THE HELP OF VERY MOIST CLOTH OR TISSUE.THIS MAY HELP YOU. GOOD LUCK.
