Hi everyone.
So a few months ago I purchased a 7900 on craigslist for super cheep because it had a clogged LLK and the guy couldn't get rid of and he didn't have time to fix it. I did a little research before hand and saw that this seems to be a common issue but figured I could handle it (i have a descent amount of experience with 7880's) and if worse came to worse, I would replace the head.
So.. I started with cleaning the wiper blade and replacing the cart. Ran a dozen or so pair cleanings in maintenance mode at differing levels. Ended up pumping about 3/4 of a new LLK through the head and down the drain.... And the clog only got worse.. I have used the Windex on a paper towel trick on the 7880 but read in a couple places that it doesn't work on a 7900's. Still I decided to try it and..... SURPRISE! it didn't work.
After all this the nozzle check is worse off than when I first got it (see attached pic). I know the guy I purchased it from tried cleaning it multiple times and have a feeling he did a SS cleaning in his attempt to clear it.
My assumption at this point is that the head needs replacement based on the face that I was able to pump 100mL + through the LLK head but when I print a nozzle check only a few nozzles are actually able to fire.
Does this sound like a reasonable conclusion?
Finally, If I do purchase a new head has anyone purchased one through
http://www.zhenxiongltd.com/ ? I read about them from a post on
http://myx900.com/ . It appears they are based out of China and im assuming would be cheaper than buying direct from Epson.
Thank you all in advance for your help. This seems like a great place to gain knowledge on these printers.
Cheers, Davis
