@ bestfred - First of all, welcome to LuLa. Next, this is an old thread and Jack has not been here for over a year and a half. Next, this thread is about a 9900 and you have a 9700 - a different beast altogether. And finally, Your NC is crap. Perform head, wiper and flushing box cleaning until you get a good NC then perform a head alignment.    - Jim

Caught me ;^(  I wasn't paying attention to the date(s), but because it was apparently active I decided to reply.  Oh well, perhaps someone else can benefit.

Hi all I know this is an old thread... but it's the only one that I have found that matches my exact same problem. In short when I run nozzle test print I get the exact same problem as Jack did. Only difference is that mine is with the Photo/Matte channel vs the LLK channel. I am really hoping that it is not a failed print head. I had a really bad clog the other day after a recent move and the printer was sitting for a bit (but I did run nozzle test patterns)... In short, I tried to clear it, swapped photo/matte ink, etc. I noticed the problem after I tried using Piezo Flush per their instructions with a paper towel. Please feel free to reach out to me. I've tried doing manual head alignment as well as auto. Also when I did try to swap photo black for matte I got an error saying that it could not complete the auto clean cycle.... several times. What a big waist of ink....

Any and all help is welcome.

Thanks everyone.

If you flushed a line, a recharge doesnít always fill the lines correctly and residual flush fluid can hang around in the head. It usually clears up after a few pages, depending on the color being printed and the color affected.

  Also a charge after a flush often leaves some bubbles.  Normally the head and dampers will resolve those, but old dampers can get sticky and may let the bubbles move to the nozzles instead of bleeding it out - same symptom as a clogged nozzle, as no ink is coming out.. You might try printing something to get a little more ink moving through the lines to clear them out.  If you only flushed one channel, you might try printing a large document that would use primarily the color you needed to flush (black, gray, light gray).

Just some thoughts.  several other things that cause banding, such as paper advance adjustment, improper paper thickness setting. Iím guessing this isnít the case since it doesnít sound like anything changed, but you might double check.

Definitely check the things Wayne talks about, and that Tyler talked about in the old portion of this thread. But in my experience, nozzle check patterns like this indicate a failed head. There's nothing I could ever identify in the paper feed, platen level, head alignment, cleaning options, etc. that can cause a consistent and discrete part of a head channel to deflect like this while the rest of the channel prints in good alignment. I believe it's the head surface itself physically failing, and a block of nozzles are misfiring. If it does what happens in my experience, the block of nozzles in this section eventually will just stop firing and no ink will lay down in this section.

Hopefully it's something else in your case, but that's my best estimate what's going on...

I've seen this nozzle pattern with the bulging on each side twice, once on a 7600 and again last year on the 9900.  In both instances the ONLY cure, after trying everything mentioned here, was a new print head.  I hope you might be able to overcome this issue yourself, but the tech told me this sort of pattern indicates a dead head about 95-99% of the time.  Good luck with your attempts to find a fix.

Similar problem this past fall on my 9900 yellow channel.
Banding persisted and elected to have it repaired.
2 service calls, a flushing box and print head later I was down $2900.
Runs like a charm.

Just a side note Epson called and wanted to do a review on my service call.
After telling him how good the technician and service call was I read him the riot act about the cost.
$175 and hour for a technician with a screwdriver pouch?? Heck he did not even have a pickup truck or a ladder..
He politely thanked me and hung up. Well at least I felt a little better after the vent.

Great job Dan.  Two thumbs up!

Can someone tell me if this is the head going bad on my Epson 9900?  I have attached a image.  Nozzle check is good, head alignments are good.  I have tried high speed off and on.  I was in the middle of a pretty big run and the banding started at about the 10th sheet of the same image and I can't get it to go away.

Looks like you're losing the Cyan channel.  Even though the nozzle check pattern looks good at first glance, I always take a second and third look and in some case use a loupe to be certain.  It can be deceiving.  Could also be the Lt. Cyan, but I'm sure that eventually it will show in a nozzle check.  You didn't mention what res you are printing at, 1440 or 2880.  I would suggest 2880 and high speed off if you haven't done so already.

Thanks for your response Gary.  I figured it was the cyan channel going bad.  I've tried both 2880 and 1440 with high speed off.  My 9890 will limp by until I figure out what I want to do with the 9900.  I think its time to give the Canon Pro series a try.  Pumps going bad on the 9890 and the 9900 has had constant issues since I got it.  Oddly my 4900 runs like a champ and I've had it the longest.  Epson needs to figure this out!!
