    I have the exact same problem and need a solution, please.

  • schiavellos Nov 09, 2008

    When my mfc640cw prints a black and white doc it prints very faint so you can't read the text. I have been removing the black cartridge and re-installing it before printing which has been working well because the print cleans itself but it no longer works and I am getting the faint print all the time

Many people with this problem most likely tried to use an ink refill kit thus resulting in this problem the reason being is the refill kits use a much lower quality ink thats realy not made for these type of printers thus either the print head or the tube running to the print head becomes clogged, While the cheaper soulution is to take the machine apart and try to unclog the tube or print head its probably better to just get a new machine as getting to the ink tubes and the print heads can be tricky at best, Another option to concider is get an empty black ink carterage and fill it with a mild paint thinner or rubbing alchol and try to print thus running the fluid through the tube and the print head this may clear the problem however you will want to give the alcohol or pait thinner time to dry a little prior to placing in a new ink carterage

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 LC61, bought in Nov.2010, won't print black. Recently replaced black ink along with all color inks...replaced black ink again when it quit printing...still won't work. Machine whirs...


This is common problem with Brother Printers. I am going to assume you are using Non-Brother branded ink cartridges. Brother cartridges have a cleanser in the ink that most generic cartridges don't have. This in turn causes the jets to clog and not allow ink to pass through them. The fix is to go buy a couple of Brother cartridges and do a cleaning with those cartridges. You may spend some money doing this as a cleaning wastes a lot of ink, but it will clean the injection lines and fix the printer. You could also consider buying a new printer. I know this is not the answer you were looking for, but it is the true answer. I just bought a new printer due to this fact.

In case of a problem or clarification or my solution was insufficient, don't hesitate to post me a reply.

If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

Black catridge not functioning . The printer shows its absence d


You do not mention what brand of printer you have or cartridges.

Did you use Epson Genuine Cartridges? Brother Genuine Cartirdges????
ALL…. Epson & Brother Requires Genuine Epson Cartridges. !!!!!!!!
That sounds like your problem.

In Purchasing Epson's CX 5400, CX4600, & CX7400 and more, I found out that Epson does not like Generic Printer Cartridges. I also Purchased a Brother. That also does not like Generic Print Cartridges. Color that should be Yellow, will turn out Green, Blue Brown, etc.

These printers have a CHIP that will detect if it is Generic or Genuine. When they see it’s Generic Cartridges, it will print lines thru the words, stripes across the picture and also do a mix match with the colors. It also will not let you print anything, if only one of the cartridges is empty.

I wanted to print only Black, and would not let me, because I did not have any ink in one of my cyan cartridges. Go figure.

That's what these Companies do., so they can keep selling the ink cartridges. Some Printers, are able to use Generic, and some are refillable. Some you can refill them up yourself and I heard, quite MESSY.

So I learned, thru trial and error, that you must use the ORIGINAL Genuine Cartridges for these PRINTERS. Some people say some models work fine compatible, but not mine.......


I had to replace the printer, but Epson, Lexmark & Brothers are always on sale. My Brother & Epson cost me $50.00 with Rebate. .

This is the only advice I can give you. If you find this helpful, pls rate me.

Thanks and Good Luck :0)

Black ink on my Brother MFC-420CN is faint and streaky


You said you replaced the cartridges. Were they Genuine Brothers' Cartridges?

My Brother MFC-240C, does not like Generic Printer Cartridges. That sounds like your problem. Also I had with Brother's was problem with Color. Color that should be Yellow, will turn out Green, or Blue Green, etc. The Generic Cartridges, also printed lines thru the words. That's what the Companies do., so they can keep selling the ink cartridges.

Some Printers, are able to use Generic, but you have to fill them up yourself and I heard, quite MESSY, or Take them to have them filled.

So I learned, thru trial and error, that you must use the ORIGINAL Genuine Cartridges for the PRINTERS.

Black won't print!!


Hi denzirelli, Apparently several reviews of this printer say it is known for poor print quality when dealing with graphics AND the tubes can become blocked. As far as troubleshooting goes if you haven?t done so already purchase a new set of official Brother ink jet cartridges, black and color. The newer ink jets are a lot smarter and remember the last couple of cartridge serial numbers. If that doesn?t work then try running the nozzle cleaning utility a couple of times. If that fails call the Brother and let them walk you through the troubleshooting process. I don?t suggest you lie, just don't volunteer the fact that you were evil and tried to deprive them of their profit. Worst case they won?t do a warrantee replacement, best case is you?ll have a working printer. If you don?t want to pursue the above option or if tech support won?t help then we?re back to troubleshooting again, when you say it doesn?t print black does that mean colors do print? If that?s the case then I suspect the black tube or the nozzles are blocked. From what I?ve read it?s a little bit of a pain to remove the print head but the key is not to disconnect the tubes. Remove the print head and the cartridge container as a unit. The ribbon cables have to be unplugged from the circuit board. Disconnect the belt and you should be able to take the print head out and clean it. Let us know how it turns out and don?t forget to rate the posting.
