Bypass Empty cartridge Brother Printer to Keep Printing

If you are like me, you bought your Brother scanner printer because you wanted a decent scanner and perhaps the odd black and white print.  Nothing more.  That’s why you didn’t pay a lot.

Well, built into the ‘cheap printer’ business model at Brother is a nasty little trick which says ‘When their colour cartridge runs out (which is really small) then stop printer from printing *everything* – including black and white – even though it’s full!”

Now that is just dirty.

I turned off colour printing on computer and it still refused to print with some bogus message like ‘cannot maintain print quality’.  Really?  I have a fully black and white cartridge and I’m not printing colour and it cannot maintain print quality?  I call BS, Brother.

Thankfully, the solution was super, duper crazy easy.  Thanks very much to these guys here

Just take some electricians tape (don’t bother with sharpie markers or other ideas as I tried other stuff on my desk) and get some small scissors (or exacto knife probably easier and more accurate) and cut some black electricians tape so that the tape *perfectly* covers the plastic clear window.

Note: you can see a small gap in this photo example which you should avoid.  Aim for 100% coverage of the window or it may not work.  I tried one with a slightly larger gap and it failed (their lasers are very accurate!)

Once the lasers kick in and hit the tap your screen will show a nice full cartridge and printing in Black and white (or whatever colour you have left) should work.

Enjoy!

  1. fantastic ! It works on mfc-j480dw. Just say yes when the printer asks if the cartridge is replaced.

  2. Thank You! This bypass procedure was successful on my MFC-J480DW, but I had a bit of trial-and-error. Brother is making the gap above the window very narrow. I discovered it must remain open for the laser check to pass through. I made sure to clear the gap by holding a thin nail and carefully running it back and forth to remove residual tape. I’m going to keep this ‘taped’ empty color cartridge as my bypass tool for future use in similar circumstances. Now I can proceed to print critical road detour info for my guests. All my other cartridges, including black, had plenty of ink! Thank you, Wayne.

  3. You’re a genius!! Worked like a charm. I can’t thank you enough! I’ve been SOOOO frustrated, especially after my brand new cyan cartridge ran out after cleaning and some test pages.

  4. Doesn’t seem to work on the MFC-J6520DW model however I have just discovered that when the ink is low, pull it out, tilt the cartridge around a bit and put it back in. Shows full ink again!! Hoping to finally use all the ink instead of it saying replace when it’s still half full.
    Just to note that it can be temperamental and if it cannot find the cartridge or shows empty, just tilt the printer back as you put it in and it seems to work.

    1. Yeah. these cheap printers are a scam and bad for wastage. Bad business model. Typically the printers just read ‘did someone open and close and put new ink in?” if yes, put indicator to ‘full’. I doubt they can actually read how much ink is in before it hits the bottom. Once it’s nearly gone I think they have sensors in there to warn you and tell you. I think some printers use lasers to shoot the ink and when the laser beam is able to go through the ink and hit the other side, because it’s not hitting the ink, then it says ‘ink low’. Each machine is different but most are a scam.

  5. For some reason it is not working for me. I have a MFC-J491DW. What is so aggravating is that I literally have not printed one sheet of colored paper since the last time I replaced my cartridges and they are all empty and it hasn’t been that long. If I only print black and white how in the world does it use my colored ink?

    1. Well part is digital. They have ‘counters’ built into the software of the printer that says how many pages printed. I have heard of printers that ‘just stop working’ once they hit a certain number of pages and then you reset the counter and ‘magic’ – it starts working. Also, it could be physical so perhaps the nozzles dried up? Maybe take them out and check if they are dried up? Anyway, have fun and good job trying to beat the machine! 🙂

  6. Just bought a secondhand MFC-J5330DW for $50. Ordered some generic XL cartridges, But nice to be able to check I hadn’t bought a dud. The black was empty, with no way to over-ride the global printer disable function when a cartridge is empty.
    I put some electrical tape over the cartridge window and says is now full – which of course it isn’t. But at least I can get a few more prints whilst waiting for the replacements. When removing the cartridges I did have to close the door, then open and insert the “doctored” cartridge for the fix to be detected.
    Anyway thanks for the tip.

    1. My strategy is always simply ‘try to beat the machine’… Sometimes we win. Sometimes we lose…
