Before we work on the computer end let's first work on the printers alignment/magenta problem.
Remove all the ink cartridges from the machine
Then clean the contacts on the cartridges as well as inside the machine itself
Do this with a small amount of warm water on a cotton swab until no ink comes off on the swab
If any of the other cartridges are low, empty, leaking or bulging replace them
Then turn off the machine and unplug it for 70 seconds
Plug it back it and wait for the insert cartridges message
Insert the cartridges and check to see if the problem is still there.
If it is Open the machine and remove the ink cartridges then look inside with a flash light and make sure nothing is in the path of the carriage.
Then turn off the machine and wait 30 seconds. Turn it back on and wait for the insert cartridge message. Then reinsert the cartridges into the machine.
Then move the cradle back and forth a few times manually by hand.
Then close the cartridges access door and turn the machine off.
Then unplug it and wait 10 minutes.
After 10 minutes plug it back in and turn it on.
If it is still there after that it means the print head has failed. In order to fix this the print head inside the printer needs to be replaced. The print head is the part of the printer that puts ink from the cartridges onto the page and is also used to detect the cartridges. Unfortunately this can sometimes cost more to replace then the machine itself.
Just in case before replacing that part The next step would be to try a print head cleaning kit like this one: Click Here
It says Brother but the kits are not specific to any one brand every kit comes with the same thing. A solution that dissolves dried ink that may be on the sensors or in the ink line a syringe and instructions. If this still does not work it is it means the print head has failed. In order to fix this the print head inside the printer needs to be replaced. After all the troubleshooting we have done if the problem is still there I am sorry to say you indeed are going to require a new part. I know this is not what you want to here but I want to make sure I am honest with the information I provide you. You would need to replace the print head in order to fix this issue. I wish there was another way but with everything you have posted I am confident this is the problem with your machine. The reason for this is he print head is the part of the printer that puts ink from the cartridges onto the page. Over time these parts deteriorate and need to be replaced, excess use or using generic inks can also cause this.
