put that cartridge in and perform a head cleaning process, and allignment... follow the procedure (2 or 3 times if needed) and in the end, shut down the printer, disconnect usb cable (both end), then wait for some time, aprox. 20 sec. and then put both end in again, turn printer on and wait for ready signal or some sort of confirmation that all is ok... If not, replace or update the printer driver and software, or reinstall all printer software.
I removed the black ink cartridge that was REFILLED at a popular retail outfit and replaced it with a remanufactured one I bought on the web. As soon as I closed the lid, the flashing stopped and it has been working GREAT ever since. Many postings had already recommended the changing to a "new cartridge" to remedy this flashing lights and "pen failure."
The print head is clogged.Try powerful cleaning: Press menu, then start black copy, then four times arrow-up quickly after another.Machine will be in maintenance mode (all lights will flash). Press 7-6-4 and OK (or start-black-copy). When finished press 7-6-3 then start black copy, printer will do a power purge. Leave maintenance mode by pressing 9-9. If this not help better think about new printer, because cost of repairing this one is profitable.

If cyan ink cartridge is not OEM, try with OEM ink cartridge. If this not help better think about new printer, because cost of repairing this one is profitable.
Perhaps the CMY color heads need alignment. If you have not already done so, run a head alignment from the driver maintenance section. It will print out a page containing several lines and text, and request you select the closest-aligned images. After this is done, do another image print to check for improvements. Normally, the printer uses the black cartridge for text and the CMY inks for images (even for black on photo and specialty paper). So when you are printing normal text pages on plain paper, only the black ink is used. A good check for this would be to print a normal text page, but select photo paper in the driver to trick the printer into using the CMY inks to make a substitute black text page. If this looks ok, then you are having issues other than cartridge alignment.
