Solve : Printer won't print black?

1.	Solve : Printer won't print black?
Answer» I have a canon Pixma MP780 and I replaced all cartridges and test page printed fine. Made SEVERAL BLACK copies and then noticed some of page was not printing well so I ran the clean nozzle and maintenance things. Now when I press black copy it prints red. Cannot GET it to print black. Have checked and rechecked cartridges ETC but have had not luck. Any suggestions?hmmm that is very strange indeed, have you tryed a SIMPLE reinstall ?Yes, I did uninstall and reinstall.
