Black ink won't print

Inkjet printers need to be used frequently to prevent inkdrying out in the print head nozzles.
If the print head cleaning maintenance routine does not clear the blockages,then print head needs replacing, but it may be expensive.
It may be more cost effective to buy a later model and better printer thanreplace the print head.

The black will not print. I have replaced the cartridge with two new ones. Color prints ok. Brother mfc 5840cn

please perform head cleaning to see if there is any ink out.. goto ink management and select head cleaning... after that goto ink management and print the nozzle check.. see if there is any black ink out...if no ink out..then more probably your print head is badly clogged..and you will need to get it replaced.

I changed all Print cartridges-Black, Yellow,Cyan,Blue

On this machine you have to install inks with power on and use the ink button and choose replace ink. If you just plug them in it won't register and reset the counts. You may need to run clean cycles at least twice to get proper colors.

Light/faint prints usually are a result from clogged ink or air bubbles between the cartridge and print head (thus changing cartridge wont fix problem). Try printing the test page print from the machine (Ink Management -> set/ok twice). Answer the question(s) in the display and repeat this up to five times. The colors should be improved after 1-3 test prints usually.

That might be because of generic ink!
This generic ink destroys the nozzels due to a chemical reaction!

If you re lucky you will have good results when useing original brother ink carts.

Run the cleaning procedure twice after you have inserted the original carts!
