RE:Cannot print in documents

It's one of two problems, either the nozzles in the cartridge are clogged or your printing preferences are set to "print in grayscale." To clear the nozzles try running the printer through a "deep cleaning" cycle from the printer's maintenance screen (available from the printer's properties). To check the printing preferences go to the printer's properties, as well, from Start > Control Panel > Printers & Faxes > right-click on the printer and choose Printing Preferences. Make sure to uncheck "Print In Grayscale."
