I tried blocking the clear ridge on the cartridges with small strips cut off of mailing labels, and it works!!! I made sure both sides of the ridge and the end was covered and I’ve had no problems! My cartridges are reading as completely full! Now all I have to do is pop ‘em out and stick ‘em back in if it gives me grief. This works very well for me, as this machine is only used for scanning, faxing, and copying, all of which print on our Magicolor 2430DL color laser printer instead of this ink hog.

I had the “no cartridge” error on a MFC 665CW, #23 solved the problem. One small difference. The “ink viewing windows” (for lack of a proper name) are located on the front edge, center of my cartridge. It is easily recognized because it is the only transparent portion on the cartridge.

Thank you so much for your help! Putting masking tape over the sensor on the ink cartridge worked instantly! Yay!

I’ve had a brother MFC420CN for a couple years. I agree totally with the comments above about the ink (specifically yellow and “no ink ” messages. I am currently dealing with ” unable to initialize” with a print job.The printer is communicating with my computer, as I’m getting connections with the flash memory functions. I’m not a novice at this stuff, as I’ve spent almost 30 years in computer maintenance and operations for the air force. I’m convinced that the problem is in the electronic interface circuitry….e.g. don’t waste anymore of my time troubleshooting, toss the thing in the trash, and go back to buying Canon or Lexmark products. both of which I’ve had great great product reliability, and they have none of the “built in” ink problems.

OMG # 23 I LOVE YOU. I just clogged the clear part of the cartridge that shows if the cartridge has ink in it or not with some tape and shoved her in there. Worked fantastically!

Solution # 23 worked! Thanks so much! I have a MCF 640 CW and was getting message that ink cartridges showing yellow and cyan not installed when I had just put brand new Brother LC41 cartridges in place — and they were in correctly and securely… Tried the sticker solution and it worked here. Wonderful — really appreciate the help and this message board.
