[Brother GT-541] My gt 541 is not printing yellow at all!!
My printer is not printing yellow at all!! This is the first time this has happened. Right after we cleaned the wiper with the swabs. Someone suggested that the head might be bad. Can anyone help if they have gone through something like this? A color wheel I test with pretty much prints all blue and red without yellow, greens, oranges, etc. Please help!
I read another post and somebody suggested that this might be the cause of an air bubble in the ink line, which I think I see in mine. What can I do?
I dont have a brother, but one of our other members had this exact same problem with Yellow. Here is a link to his thread HELP! Random clogging in the yellow print head.... Hopefully this can offer some help

Thank you I think I have read pretty much all the forums about air bubbles, certain color not printing, etc. We do have a substantial problem with air bubble thats totally visible but don't know how to get the air out to get the ink flow. We were told it's the head from the techs, but hopefully it is just an air bubble situation. If you come across anything how to get the air out I would really appreciate it!
Unfortunately, I did eventually have to utilize the Brother print head refurbishment program; they basically send you a forwarded (and refurbished) print head, to get you back on your feet, then you send your clogged print head in to them for servicing. If they are able to repair your print head, you pay around $300. If they can't, you pay the rate for a refurbished print head (which is somewhere around $700-$800; I can't recall). It is really nice to know that they will get you back on your feet, if you need it. The down side; you only use the service after you are convinced that your print head is beyond your repair expertise, so you inevitably spend valuable time trying to fix the problem, before taking advantage of this service. The alternative, of course, is to immediately jump to the conclusion that you need a forwarded print head, any time you can't resolve a clog in a timely manner. This would be good, if it didn't cost $300 a pop for the service. But hey, everyone has to make their money! Maybe that's why they won't spill their techniques....
Sadly, I have found that ANY air bubbles in your line (which are introduced through a number of methods, apparently) can render a Brother print head as "useless"; although not necessarily beyond repair. I am not sure what magic they use at that facility of theirs, but I would be interested in learning from them, as they are experts in unclogging Brother print heads. I do not think that the print head, itself, is inferior in any way, but I was told by a Brother tech that there are no filter elements between the ink lines and the print heads; I am not sure how true this is, but that is what I was told. Therefore, air bubbles and slight contamination can be disastrous. In contrast, I believe all Epson based printers have filters or dampers to protect against such things. I do not remember if the Kornit had anything like that, but I am pretty sure it did; I would have to go through some of my old pictures, to refresh my memory.

Justin, who told you this? This is contrary to what I have been told. It is my understanding that the filters in your printer are a part of the print head and are not removable (at least by the user). I was also told that the filters on the CMYK print heads are different than the filters on the White print heads for the GT-782. This information I received was coming from the senior people at Brother. But I personally have never seen a print head taken a part.

That can is a conditional? I have seen bubbles come and go and my print heads ( touch wood ) are still in prime condition. At some point there are nozzels not printing but nothing that a head clean will not fix and sure not as bad as rendering heads unusable. May be luck, may be different bubbles we are talking about.
On another point, Wouldn't it be nice to have the schematics for those heads so we are aware why things go awry with bubbles or whatever contingencies might occur?
To the OP, have you tried cleaning the head itself ,phiscally ( probably have), after cleaning the head caps or wiper many times the machine missbehaves on me and many head cleanings are necessary to get it back on track.
Also might summer have anything to do with all this problems? Heat, humidity, and so on. It just seems strange that problems arise from nothing to a non functioning print head, and that the last two people in this forum posting about it, have had issues with the same color print head, or might be color batch, is yellow more sensitve to the bubbles due to the special nature of the ink set? ( like red that doesn't dry as fast as the other colors?)questions, questions.

Good questions! I am not sure of the details, and I am not even sure if I fully believe that air bubble scan be so damaging. However, having now had to replace a print head, and having Brother reps tell me repeatedly that it was the "air bubbles" in the system (not just me, either; many other users have been told that their print heads were destroyed this way), I am just passing along what I have been told..... Personally, I would be far more inclined to believe a bad batch of ink, or some other such condition, caused the problems.
