Out of the blue (I suppose it is always that way) I started having serious and stubborn and very inconvenient blocked nozzles in my LLK (p600, Cone Color Ink) . I’ve been vigilant about printing nearly daily, keeping carts full, and keeping room humidified. This is what is repeatedly happening: I get a good nozzle check, print an image, check my nozzles again, and proceed to print another image. Half way through the LLK stops printing. After several days of work (head cleaning, letting head rest on PF-saturated paper towel, the usual) it looks fine until after I’ve printed out a couple of images. Then the sequence repeats itself.
I am usually very good, with patience, at fixing blocked nozzles. This time I’m stuck! I’m ready to give up digital prints and just stick with dig neg printing (on my p800)–it’s so much easier it seems.
Does this sound like a cartridge problem? vs a Head Problem?
I have 3 options to try to answer that question on my own, though I’m not sure I would be able to interpret my results definitively.
1–Stick in an old LLK cart with ink that is about a year old
2-Replace the chip on a spare cart and fill the spare cart with LLK
3-Replace the chip on a spare cart and test with Piezo Flush.
#1 May cause problems because the ink is old.
#2 This sounds easy
#3 This sounds like a lot of work since I would then have to deal with removing the flush from the lines.
Any thoughts?
Thanks.
