Fuzzy lines

[Ricki Susic]

I recently bought a second hand XJ-640 and during a adjustment of the bi-direction I discovered these blurry lines.
The printer is loaded with Cmyk + lm and lc

IT seems like cyan, magenta and yellow lines are sharp looking as expected, and the blurriness only appears to be with the Black, light cyan and light magenta.

What do I do about it? Is it due to bad heads that needs replacement, or is the probleme to be found elsewhere?

Best Regards
Ricki

What's your nozzle check look like? I'm guessing it has a lot of deflections.

Not too bad, I think

Looks like the black is deflecting pretty bad but the LC and LM are better minus the missing nozzles in the LC. I'd pop in some new cap tops and flush the pump tubes to see if I could recover the those heads a little better.

Thanks for the reply. Can you point me in the direction of a "how-to"?

Unfortunately I don't have anything for that model but you might find the service manual online. A lot of times someone here on Signs101 will have one to send you. Good luck!

But thank you anyway.
