INK CARTRIDGES WILL NOT REGISTER AS NEW WILL NOT PRINT

Are you sure its exclamation mark?..
This warning message related to print head. (warn out). When you are replacing ink tube assembly use dummy print heads to do the priming (new ink tubes are empty & they have to fill with ink)..
Action: Remove all cartridges and print heads, switch on the printer follow the screen message.(Insert cartridges first next dummy print heads).once its recognizes cartridges then it switch over to print heads,insert dummy print heads. Once printer recognized the dummy print heads, printer will perform priming, during priming dummy print heads will filled with respective inks.(follow the display message)Remove dummy print heads & insert normal print heads. Wait till printer recognizes print heads, load the paper & wait till performs the calibration, once calibration is successfully done issue closed.
If calibration not successfully done, check align print out for which print head is not printed properly, replace it..
Pl ensure that minimum 50% ink levels required in cartridges before performing the priming. Best of luck..

All the ink cartridges need to have ink in them to allow you to print, even if you only want to print in black only.

Are you sure catridges are brand new? check any where ink is leaking? if its leaking try to arrest it or replace ink tube assm.Dont try to clean print heads every time it will consumes ink...

you need to have authentic hp cartridges,if you bought cheaper,it will not work.

press reset bton 10 scnd

Run a head cleaning and try another nozzle check ..

Best luck

My MFC-420CN acts up occationally. Remove the new cartridge, hold it as you would to install it, Rotate it to the right about 45°. Snap it with the back of a finger (dislodges any air bubbles in ink feed). Reinstall cartridge (ensure it is fully seated. This works for both Brother cartridges and the eforcity cartridges I've been using for the past couple of years. HTH

Normal 0 Driver could be corrupt.
Disconnect the printer or at least be sure it is turned off. I'd do both and reinstall the CD software program that came withthe printer. When the software program asks you to connect theprinter to the USB port, do so and it should again work properly.
Hope this helps. Bud

There is a design reason why the print heads are changed when you change an ink cartridge is changed. The print head isn't made to be reused and the quality of your print will suffer at some point if you reuse the same print head 6 or 7 times. I would get new cartridges and be happy with the print quality that a new cartridges will bring.

you need to print only in black if that is all the ink you have, and also you need to remove the color cartridge as it still registers in the printer as able to be used, although it is empty or near so. Did you remove the tape over the print head fron the new ink cartridge? Do a print head alignment, or use the toolbox icon to tell the printer that you just replaced the cartridge. Some HP models chip the ink cartridges so even a refill wont register as a full tank and the printer wont print. chip needs to be reset (difficult) or just replaced with a new cartridge.
