I have a Designjet T520.  After changing one of the ink cartilages it began throwing this error and will not print.  I followed the trouble shooting tips, which are very lack, and have replaced all the ink cartridges without an success.  What is the fix for this error?

Error 51.1.10 is a Ink Cartridge Cover sensor failure.  Recommendation: Replace Ink Cartridge Cover sensor PCA, CQ890-67028.
