Everything needs to be checked out. The maintenance tab on the
properties screen allows you to print a test pattern. Sorry to
say, check out everything, returning to that test print tab to
check if it has come alive. The one time mine totally quit
printing was when I got some liquid under the contacts of the
print head connection. Remove the entire head, and check that it
is clean and unblemished. As I said, when it will print that
pattern, it is OK. ..

    Good luck.
