Question about Brother MFC 490cw Color Inkjet Multi-Function Printer
At Start was not printing black. Going through cleaning many times had no effect. At some point it asked to replace cartridges. I knew the black was low so I replaced it. Next it started asking to replace all cartridges. I did. Now it keep asking to reinstall magenta and sometimes cyan, "cannot detect cartridge" And it won't print at all.

This could be because of several probs: 1. The ink cart is not original and wont let the ink flow, because the valve is not open. 2. There might be air bubbles within the capillaries. 3. The ink is not genuine ink and has pigments in it. Solution: see here, too: http://welcome.solutions.brother.com/bsc/public/us/us/en/faq/faq_top.htm?reg=us&c=us&lang=en&prod=dcp110c_us Insert another ink cart. Use, if possible, the genuine ink cart from brother. Do the cleaning cycle twice. This will extract the air bubbles out of the caps after the second time. If you dont have any success the printhead is clogged and cant be cleaned anymore!

Third place I'm posting this today... This solution worked for me:
This is a simple fix. This printer uses a LIGHT SENSOR to detect if the cartridge is installed properly. Numerous things can allow extra light to enter... your solution is this:
Get electrical tape (duct tape may be too thick) and cover the rear sides of your cartridge; along with the recessed square shaped area that is directly in the center of your cartridge. Cut the tape so that you can cover this area without impeding the shape of the cartridge (so it can still be inserted and removed easily) I have used this solution to repair this exact problem on MFC-665CW when installing a continuous ink supply (in place of the original cartridges) You can actually just tape the internal sensor and close the front cover if you want to test it without any cartridge at all (though its not a good idea to print like that as I"m not sure if it will damage the unit) Those of you wishing to only buy Black ink can attempt this if you dont care about voiding the warranty or possibly breaking the unit... just cover the other slots with electric tape.

51.22 is a Magenta laser scanner error.
Try removing the magenta restarting the printer and reinstalling.
If that does not work you likely need a laser assm.
You might want to call a tech. to replace.
