After I put the new Magenta Cartridge into my printer, the reds looked faded on the test prints. I removed the cartridge, cleaned the area, gave the cartridge a good shake, and put it back into the printer. No change - still faded reds. I'm very disappointed. I purchased the HP cartridge specifically so this would not happen (after reading the reviews of cheaper re-manufactured units). Now I have to ask for and wait on a replacement ... if I can get one. Lesson learned - if you're going to pay full price anyway, buy from a local supplier.
