Unusable as ink dries and printer thus becomes unusable

After inserting the ink cartridges and print some of the printer (Epsond WF-3520) has not been used for a few weeks. Then the nozzles were clogged / dried out so that the prints were provided with strong strips. Even a multiple run the cleaning program first brought only a mediocre improvement. Only after the exchange of all Tintenpatronenetlichen and many other print turned back on a good printed image. The Service sent me for the circumstances kindly a new pack ink cartridges free of charge.

Now I was about to return to print something. Unfortunately not - all dried up.

Conclusion:
I'll throw the Tintenparonen in the Tonnne since these dry within a short time and make the printer inoperable.

Addendum:
Meanwhile, I have found that possibly poor copies (Epsond WF-3520) are not available to dried ink, but the fact that the ink tank were just empty, even though the fuel gauge has displayed for about 1/4 capacity.

Conclusion 2:
When ink exists, I find the expression (also colored) really good. However Tankfüllanzeige indicates always more than in the cartridge is actually in it. The cost / Nutzenfakotr deteriorates from there to the detriment of the buyer. However, since the cartridges are very cheap, I'll use this yet further. Therefore, from now 3 star.

Conclusion 3:
Today me the product has already extremely annoyed. Performed three times cleaning and printed 16 pages. Printouts are provided with strips and areas where nothing is printed. Now it really is enough. The last reserve package I have now moved to the cartridges that were used in the trash. Now I have a go KMP E125V ...
