Extremely likely
I have a Latex 360 issue that keeps on repeating for a while now. Latex ink keeps on building on printheads. Usually it builds on top and bottom of printheads, but it also gets on the sides of the printhead. This is a very thick and hard residue, that can be sracthed away only using stronger mechanical pressure (i.e. fingernails). This buildup happens in the matter of hours from the beginning of printing, sometimes only after 5-10 metres. The buildup completely covers the nozzles, so a part of the printhead covered can't print any ink. This creates terrible color issues, banding and color mismatch. This issue affects all printheads, except so far the optimizer printhead. Thi one seems to have no issues. I've changed printheads multiple times, had the carriage cleaned recently, changed the ink, cleaned the ink systems etc. No help. The only thing I can do is to take out the printheads, clean them manually and reinstall them. This only works until the printhead gets clogged again, which is after another 5-10 metres of printing. It's a terrbile issue that makes the printer completely unusable for anything except the most simple of jobs, and even ther I dread using it.
PS: the local HP reepresentatives and service guys seem completely out of ideas. Except the ususal "replace the printheads" (which I did numerous times) there is nothing they can do.
I'll attach some pictures of the ink residue. Anybody had a similar issue, please help.
