How to trick your printer’s sensors into letting you print b/w when you’re out of color ink

Cannot Print. The printer does not have enough ink to maintain print quality.

I bought some movie tickets online the other day and had about 10 minutes to print my tickets before I had to run out the door. I hit print and looked expectantly at my printer, but as usual it was blinking at me saying that one of my color cartridges was empty. I rummaged through my ‘stuff’ drawer and noticed that I was clean out of ink, so I switched adobe reader to print in greyscale and hit print again. My black cartridge was full and brand new, but the printer said this:

Are you kidding me? Not enough ink to maintain image quality? on a black and white document? Obviously my lovely printer manufacturer (I have a Brother MFC-495CW) is trying to make more money on ink cartridge sales. Tough luck. So I pulled out one of the color cartridges and took a peek. This is what I saw:

The ink cartridge has a little window on it that shows you how much ink is left inside. After a bit of searching the web, I found out that the printer shines a light through the ink window to see how much ink is left. So I proceeded to see if I could fool the printer into seeing ink in the cartridge. I first tried to sharpie the window but that didnt seem to help.

Next, I grabbed a roll of electrical tape and stuck some on a few strategic spots as you can see below

Success! All three cartridges are now showing as full!

Some of you may be wondering if you lose print quality if you dont select greyscale mode at this point. Dont worry, I’ll show you what happens with a little help from Teddy Roosevelt:

It seems like a lack of color cartridges has little negative effect. Success!

    I live in the Caribbean and spend $450. tt dollars for ink. Ridiculous because yellow always runs out. The tape is a $$$ saver …thanks

    Thank you !! I always buy the colours but barely use them and if they do get used they wear out so quickly – you have saved me some $$$
    I could not find tape so I coloured it in with permanent black texta! It still worked!

    You are a boss! My printer (J315w) has been sat on the shelf for months. We have two full black toner cartridges, but the colour ones are empty and they’re really expensive to replace here, so we’ve not been using it – I’ve been using the printer at work instead. I came across this post by accident while reading something about printers, and I’m so happy right now :) I only had a black marker, which worked fine for the yellow and cyan cartridge, but didn’t work for the magenta for some reason. I managed to find an old piece of black card, though, and tore off a small part and placed it over the window. I’m now printing like a madman :D

    Thanks man! My brother printer had decided that my ink levels of all colors will slowly drop over time, even if I’m not printing or using those colors. This trick fixed everything for me!

    Thank you! Thank you! Thank you! This solution worked on my MFC-J435W. I didn’t have electrical tape so I used duct tape. I cut little stips to size and it worked perfectly!

    I am beyond amazed!!! I stmumbled across this by luck. All 3 of my color cartridges were low and kept me from printing. Couldnt find any electrical nor duck tape, so what do I have dark in my purse? Eyeliner!!!! My bf is at this point, is looking at me weird, what in the world are you doing? My reply, performing a miracle!!! It actually worked!!! :-) You are amazing! I am amazed! Thanks a bunch!

    This worked brilliantly! Instead of using tape, I just used a small strip of paper to cover the ink indicator on each of the colour catridges.
