Cyan ink doesn't print most of the time, even after multiple cleanings

You have a blockage in the print head and/or feed line from the ink cartridge to the print head. One possible fix would be to make a pad of paper kitchen towel wet it and sit the print head on it overnight. With luck the pad will soak the blockage and draw ink through the head. Give the machine two self cleans and try a print quality test to see if you have made ANY improvement. If no improvement - forget it as the blockage has been there too long.

Do a test print...
assuming you have done multiple print head cleans... if it fails to print ANY cyan, I'd guess the print head is dead... although to be honest im not an expert with this hp printer. if that is the case, it probably isnt worth repairing.
If it does print some cyan, just missing, you may be able to find info, sorry, I cant help you there, on accessing the service or maintenance mode and doing a higher level clean, if your printer supports that.
As a last option, disassembly and soaking the bottom of the print head in cleaning solution /water... overnight, without getting ANY water on any contacts, then re running print cleans.

good luck

in my exp, again, not with this printer, mind you, if a print head fails to print ANY ink for a given colour, the print head is usually faulty.

Hope this info helps

First do not use cartrigde compatible or refill because you clogged the print head,is verry sensitive.If you try to clean the print head and nothing you need to replace the print head is the only solution,after replace the print head you print all the colors.

NOTE!!! After you replace the print head use only original cartridge brother !!!!

Either the ink you are using is not going to give the color you want, or you have print heads that are blocked.

The printer cannot use photo inks like Photo Cyan or Photo Magenta. Be sure to use "BCI-6 Cyan" in position 5 - farthest to the right.

It is probably clogged. You need to using lint free swabs and vinigar to clean it. The vinigar disolves deposits of dried ink.

If this doesn't work then it can be a print head problem and that is usally cheaper to replace the printer than it is to repair it.

Try putting a solid cyan sheet on copy board and copy many times then try head clean You may need to repeat this several times

it's a multiple problem....there is no enough ink for the head managment sensor to understand the good function of the print head.
Print a nozzle check to see what is going on
Then come back for more information

talked to Brother, cost to much to fix, replaced the printer.

Try replacing the cartridge. Sometimes they do get clogged and won't clear no matter how many cleaning cycles you run.
