Fuzzy In Print

[printimage]

I am getting a fuzzy lines with any blue or black print. I was told the CR cables or the printhead is failing.
Any ideas?

Jets out on the printhead - leading to misfiring.

Might also want to look at your humidity levels...

Is there away I can check for both the misfire and humidity?

 

[Stella_FB700]

Can you run a nozzle check? or a jet mapping test?
If those all come out fine without any missing nozzles - pretty confident its humidity and static overspray.

That type of streaking is usually the print head failing electronically/physically. It could be as simple as a damaged/dirty print head cable but I would say it is more often than not just an old worn out head. As stated above, static also causes this issue and if your environment is not within the required humidity spec for the machine I would fix that first. You can find a hydrometer for a few bucks to read the humidity. But like I said, in 8 years of being a full time tech, that streaking is almost always a bad cable or just worn out head.

Could be either. The streaking you are seeing means the signal to the head is shorting out. The fact that you were getting the fuzzy prints earlier could just mean the head is progressively failing as well. The streaking could also be other electrical issues but start with the head cables and head.

I Change the head cables and it print the nozzle test, when i send a print it print the image but with the same lines over it. Could the cr cables want changing or the printhead for sure?
