Hi Good day!! Too bad i think the problem is the print head of your unit. maybe the tube inside that connects from the print head is clogged. i suggest to contact your local supplier to repair it or replace it if the unit is still in warranty process..

I guess you have used generic ink carts.

You should buy an original brother ink cart.

When done so make sure all other carts are at full level:
Press menu then start b/k copy then fourtimes arrow up (tel.index). Machine will be in maintenance mode. press 7 then 6 then 4 then start b/k copy. Machine will refresh ink within tubes and print head and do some power cleaning. when finished press 7 then 6 then 3 then start bk copy to run an extra power purge.
Leave maintenance by pressing 9 then 9.

Do run a quality test print.

If you re lucky the ph will work again.

THERE IS NO WAY TO CLEAN THE PH OUTSIDE EXCEPT BY Power Purge (7-6-3) within maintnenace mode.

If you like to save money refill ORIGINAL Carts by drilling a 2mm hole into the top (O of brother brandname) . You can leave the hole open to refill the cart next time directly without taking it out of the printer.

Mix some 3ml 85%-glycerin alc (drugstore) with 3ml of destilled water and 5 ml of DYE(!) ink and refill the c/y/m cart.

For bk mix 1 ml glycerin alc with 4ml dest. water and 15 ml bk DYE ink (shake well before refill).

This is -nearly- the exacte mixture of original brother ink.

I've had some success, if one hasn't been printing with the ink dry for awhile , through soaking the entire printhead in a bowl of alcohol. Soaked it for 1-2 days wiping it from time to time. Took awhile, but it worked. Might have to do it again soon. Bottle of rubbing alcohol 80 cents. New print head $38. Rather waste the bottle of alcohol :P

I have not had great success at all with my brother's canon. He ran it clogged for almost a year and I tried the above and it didn't work. I'd say the transistors in the print head probably overheated and it's shot so he bought a new one. Too bad Canon doesn't make it easier to buy new printheads.

take swabs and use alcohol to manually clean it...GENTLY and with not too much alcohol. You will go through several swabs. Use the foam swabs, not cotton, so you don't leave junk behind.

My Brother DCP 330C hasn't been used for a while and now does'nt print at all, just spits out a blank page. When copying it only prints yellow. Changed all the cartridges, but still the same.

you have a blocked or faulty printhead/ inksystem, you can print an internal print quality check and do deep head cleans, but in my experience this only helps 10-20% of the time.

deep head cleans use A LOT of ink

if you dont see a big improvment after 2 deep head cleans dont continue as you are just wasting ink

Manually clean print head dcp-j725dw

Explore the options on the printer display. Find maintenance and poceed from there. You will have to use menus anyway (on the computer or on the MFC display).

Brother DCP-350C magenta ink won't clean and print quality check shows multiple visible gaps

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.

The black ink on my Brother DCP-130C won't print and it's a brand new ink cartridge. I thought it was a defected cartridge so I bought another one, same thing. The other 3 colours print ok though....

I have the same problem. Everything on the printer is working just fine. It'll do a test page just fine, so everything's working right. The %$^ thing just won't print. It makes noise like it's printing when you give it a print job, but it spits out blank pages.

My brother DCP 165c printer does not print black ink, colored are okey. nothing is seen in LCD about this error

If you do not get an error in the LCD screen, it usually means that your Print head is clogged: try running a couple cleaning cycles using your printer inbuilt utility to try to 'clean' the Print head.
If this does not clear the clog head, try using a new original Brother black cartridge (which contains special solvent to prevent clogging) and repeat the cleaning cycles a couple times again.
If the problem persist, you could try buying a print head cleaning cartridge to 'dissolve the dried up ink' as Brother inkjet inbuilt print head are very difficult to access and clean!
Hope it helps & good luck!

Have two Brother DCP-145C printers and use compatible inks. Now the yellow won't print in either machine. Despite trying cleaning cycles and replacing the yellow cartridges, the test print will not show...

100% you need to replace the print head,in the future use only original cartrige brother not refill or compatible cartridge.If you want to replace the print head you need to take care is difficult to change the print head,you must to unzip the all printer.If a have been useful please give me a vote.

My DCP-115C printer was missing red colour.

Yellow is one of the colours used to produce a shade of red.

I don't know how but ther must be a way to print a test page to see if the print heads need cleaning I've never used a brother.
