Question about Brother MFC-5840CN All-In-One InkJet Printer
Like most inkjets, the print output of this device is hopeless and we never print from it. It is however very useful for multiple page scanning and for receiving faxes electronically, BUT if it believes there is a problem with one or more of the ink cartridges, it eventually reaches the point where it can't be used for anything - even those things that don't require printing!
So here's what you do. At the side of each of the cartridges nearest the right hand side of the machine (looking from the front) there are some ribs in the translucent plastic body of each cartridge. You need to black these out so that the magic eyes that attempt to see through the cartridges when they are in place cannot see right through. This cons the machine into believing that the cartridge is there and has ink in it. I did this with a little strip of black fabric tape on each one, but I'm sure insulating tape or possibly even masking tape would do just as well.
After doing this and lowering the cover, the machine will ask you to confirm whether each of the cartridges have been renewed. Tell it they have all been replaced.
Doing this should allow the parts of the machine that work ok to carry on working without interference from the part which probably never worked satisfactorily from the day the machine was made. (IMHO the world would be a much better place had ink let printers never been invented.) Cheers!

Why does my machine's LCD show "NO CARTRIDGE" even though I have already installed all the ink cartridges? Description: An ink cartridge is not installed properly. Check that the ink cartridges are installed properly and reinstall the ink cartridge following the procedures below:
If you mix the colors by installing an ink cartridge in the wrong position, clean the print head several times after correcting the cartridge installation.
Once you open an ink cartridge, install it in the machine and use it up within six months of installation. Use unopened ink cartridges by the expiration date written on the cartridge package.
If you have followed this procedure and still have the same error condition, make sure you are using Brother Genuine Supplies. Generic supplies can cause this error condition.
If the problem continues after verifying the cartridges are installed correctly and that you are using Brother Genuine Supplies, then there may be a problem with the unit. Please contact the appropriate Customer Service Center.
