I am printing with the Epson 7800 printer, operating system Mac 10.9. The printer was not used for almost a month. I ran nozzle check and had to clean the heads. This was not completely successful so I used A Simple cleaning solution to clean the heads. Ran another nozzle check and repeated the above again. The printout was mostly successful with only a couple of drop-outs. The full color nozzle check when printed was separated by a heavy blue line between the group. The other test print the linear one would have 2 thin blue lines above and below the test print. I tried to print an image. When printed, it is covered completely by thin blue horizontal lines print completely across the image and overlapping the image on the right by 1/2", the left by 1" and the top by 1". I read on line that it is possibly the ink cart. This one is and Epson cart at least 3 months old. The offending cart is the light cyan. The printer reads it as 50% full but when removed and shaken it feels almost empty.
I am in the process of changing my inks to the Cone ink system. I was told that I could change them as they became empty. I read on line that the cart could very well be bad. I just order ink and refill cart that should e due tomorrow. I don't know if this will work but if the printer is shot (maybe the heads), I don't want to keep wasting money on inks I can not use. I also own a 4880 that I want to change over to the Cone inks. I would rather spend the money there.
Does anyone have a clue as to what is happening? I have tried all of the obvious, wiper blade, head cleaning, power cleaning, etc with no effect. I will appreciate any help.
I am enclosing and image for your review. I could not get the image to upload so I have place a link to the image on my website.
Thanks in advance
