Pro-10 From paper issue to banding issue

PixelWorks

The paper issue was when using glossy, the papers I have were doing some curling, and teh edges would get ink all over them. so I curled the edges and this helped. But this happened about 10 times and a couple times the paper got hit and the printhead dragged across it. SO I raised the printhead in the Custom settings. And this degraded printing. I lowered it and stopped using that paper. Went to normal paper and then the banding started.

 

I have done normal and Deep cleaning cycles, I have printed nozzle check after nozzle check and print checks, and they are NOT looking great.

 

I have gone through 2 sets of ink tanks ($140 each set), about 25 sheets of excellent 13x19 paper, and over 2 days of time.

 

Last resort I took out the print head and put it in a water/amonia/alcohol bath for a couple hours. Also squirted water (distilled) on the head and inside to clean up. Inserted and still NOT ok. I get the banding. Its 2AM, and I am still up and working on this printer as the 3rd day.  I wonder what could be the issue?Pro-10NozzleCheck.jpg

 

 

I am at this point lost on what could be the reason. Some fibers it picked up from the paper strikes and is not coming off, or? But most are effected, not just one color. I honestly cannot make sense in reading this chart as I see ABCDE are bad, then I see F is horrible, and G has slight gaps, H is a bit better, and I is bad. J is bad, K, L,M, N are bad. O is almost half empty, P is not bad, same with Q, they are pretty OK, very slight gaps.RSTUare gapped, with U missing a line, and V is missing more. Wand X are missing a slight line, Y is not so bad.

 

Not sure what the values are saying for each row.

At first I had issues doing manual alignment. I figured how to do it, and I made the adjustments, and this too did not clear the issue.  I switched back to auto align.

In my opinion you have a print head problem. 

Until/unless you can get proper nozzle check patterns any other efforts are going to be futile.

WHat does the problem look like? Considering that the head was getting caught on the paper edge, and it was a 286gsm paper that it did damage the paper a slight bit, as it pulled less than a MM of the coating ..Could that have damaged nozzles?

 

Perhaps I will take the head out one more time and do a much more thorough cleaning with the WaterPik. But if I am pushing paper fibers back into the head behind the nozzles, they will come back to the nozzles. so, maybe a pressureized wash so it comes out the other end?  But the other end where the inks sit is the rubber gasket and a sponge like oval area ...where I think the ink enters from. Maybe I need to remove these foam ovals off each ink and then do the flush?

 

Or buy a Pro-300 print head

 

?

I have a steamer, I can try that, or a warm to semi-hot solution bath.  sit for hours, or longer, and then the waterpik, then flush out from nozzle to exit from ink tank side.  Unless I have another issue I am not aware of.

The Nozzle check patterns should look like solid boxes, NOT with lines, right?

I never get lines with my nozzle check.

This forum is pretty much you I take it? 🙂 well, thanks, but I guess this is not your area of knowledge with any depth. Wish me luck. I think the Pro300 is the same head, and they do sell a replacement fo rthat.

I do appreciate his input, and I didn't mean it to sound unappreciative. I am just being blunt with my issue and so far while he is the only one with a few suggestions, this last comment was kinda what made me a bit perplexed, as the entire time we are dealing with the printhead, and maybe the image needs to be larger to see the nozzle check better or, something.

 

But I am guessing this is a rare occurance(People having paper with curl edge)?
I have to accept that...So he maybe stumped and felt to say something, but the obvious didn't help. 

 

Someone mentioned that if my encoder strip is dirty it will never be able to do a alignment. But its a channel with no focus, so its been days, and that person may never return to it. I see the encoder strip, or at least what I think is the encoder strip, the "clear" film that runs along the with the belt. So if I know how to access that strip, I maybe able to check.

 

The printer is lightly used (got it new 2 years ago), and I have done about 500 total prints on it, including basic ship labels on standard paper, and many other receipts with 5% coverage. But recently did about 40 prints.  I also notice the CO channel maybe clogged. I get out of ink, but there is nothing actually checking the ink, it is software calculated, as the ink tank of my CO drops about 5 grams and it thinks it is out.

Ya, that was a bit snide. Sorry. Just frustrated...and feel like this is part of 2020 on a personal level.
