Whether you store it for 2 months or 2 years you will still probably have the same problem, not a dried out cart but dried ink clogging the print head. When you don't use your ink carts for a while or when you get new ink carts that have been stored in warehouses for a number of months, the print head nozzles on the bottom of the ink carts get clogged with dried ink. The printer head cleaner menu will not disolve the dried ink. Water will. Try this. Soak the bottom of the clogged ink cart in 1/2 inch of hot water for 15-30 minutes. Blot dry with clean paper towel(you should see the ink color on the towel). Retry.
