Hello.\n\n I just bought this Envy 5640 (in Japan). I get the message "Remove and reinstall the indicated ink cartridge, making sure it is correctly installed, and then touch ok" for the BLACK cartridge. I was able to print in blue with the colour for alignment, but this messge won't go away. i see this is common if I look on the Internet. and all HP tells you to do is clean the contact son the ink cartridge or call help. This is a Saturday here and they are closed. But why would this happen on a NEW printer. Could something be stuck in the cartridge holder? I did not even touch the foil after removing the cartridge. Have I got a lemon? I need this printer to work this weekend as I had to replace a C110 premium due to bad rollers. Can anyone help? Thanks!
