Red light blinking constantly.i have replaced cartridge.Help please need to print.

Hi,

Take the cart out and put it back in there might be some loose connection.
The red light flashing is caused by that bad or damaged cartridge. You can always try cleaning the electrical contacts on the cartridge and inside the ink
cartridge holder assembly, with a damp Q-Tip. Then dry the contacts with a new dry Q-Tip and retry the cartridge. If that does not help, and you still have
your old cartridge, try reinstalling it, even if its empty and see if that printer time out problem goes away.If it goes away replace the cartridge.

Hope this helps.

The green light is blinking constantly and the printer won't print

When the green lamp constantly blinking this mean one or both print head are defective.Here we can find which cartridge is defective.Open cover put out color cartridge then close cover.If blinking stops replace color cartridge.If blinking continues put out black cartridge and put in color.If blinking stops replace black cartridge, if not stop replace both cartridges.
This printer can work with only one cartridge.If you don't use color printing just remove the color cartridge.
