I have an epson all in one printer and I just started using it after a long absense. I'm having troubles because I've tried cleaning, readjusting, and all the other diagnostic options for the printer but when Printing stuff out it comes in all red with a little blue here and there. I changed the yellow and blue cartridges and it says they are full but it still doesn't work. Is there anything else I can do to try and fix this problem?
