Hi,

The nozzle may be blocked. So take out the colour cartridge and place its nozzle in a bit of water for about 10 mins. Bring it out and dab the nozzle with folded paper. If the tissue is blotted with the three colour it means you have unblocked the nozzle. Try now to print after returning the colour cartridge. You may need to repeat to get good results.

Thank you!!

my brother printer say's that printing is unable see troubleshooting and routine maintenance chapter 70

My refill my printer ink (i remove it) but still the screen appear to ask me "cannot detect black ink, reinstall slowly"

Your black printhead is blocked.
The printhead is deep inside the printer and has to be taken out by the expert and cleaned with the help of 'steam' and hot water. This is because not using the printer for a long time. or using low grade refill inks.
Please select new cartridge only if you are inserting a new cartridge or fully refilled cartridge. Otherwise use old cartridge option. Brother printer has a mechanical sensor and not the electronic chip in the ink cartridges.
After inserting the old used cartridge if you choose 'new cart' option it will show the "Full" ink. You can still print from the exhausted ink cart after covering the sensor in the middle by a piece of paper in emergency.

uninstall and reinstall the driver for the printer.
Go to Brother website to obtain the driver.

there is a strong chance that either the black cartridge has run out and will need replacing or the cartridge itself is blocked. i would first check the manual on the printer for an option to clean the cartridges.

failing this within the software on your PC for the printer there should be an option to clean the cartridges. this should sort the problem out.

if not i would purchase a new cartridge for the printer and replace the one that is in it at present to see if this resolves it.

Take the printer back to where you got it from and exchane it for another one...

Hello, please make sure that your cartdridg is well installed and that you took off all protections on it. Unplug your printer from the ac dc and replug it...
