I have done nozzle cleaning and checks and everything seems to be fine but a little line missing on one white.

My main problem is when I print I am getting horizontal lines through my pictures. I have tried alignment time after time and still am getting the same results. please help

What's the bottom of your print head look like? any dried ink that you can see? capping station and wiper in good shape?

Which printer model? What resolution. Print mode ? Rip is fast artist /rip. What version? Same in high speed / bi directional as uni directional. Both color and white layers????
Clean encoder strip and encoder wheel. As well as the previous mentioned items.
How old is the head. U can get a good nozzle ckeck but still not be getting enough ink for a good print if it starts to starve.

Normally, horizontal bands indicate need to clean.

I agree. Horizontal film that the printer head runs along needs to be cleaned carefully.

Horizontal lines in the print, usually called banding, most likely mean you have clogged nozzels in your print head. Run a nozzle check, if you don't get a perfect nozzel check then you need to perform a head cleaning (or several). Banding is not caused by a dirty encoder strip.

And as Jon mentioned you must keep the print head, wipers and capping station clean.

Sorry. Really wasn't saying that the encoder strip caused banding. My long time with ink jet printing with other machines, Roland, etc. Says banding caused by not enough ink. Dirty head
Clogged nozzles. Which leads to capping station issues. Wipers etc. As the pros from Dover are pointing out. Sometimes this can be temp fixed by increasing resolution. U seemed to have other issues and it never hurts to clean the encoder strip. But issues with the strip generally show up as erratic printing or the print head gets lost. Just covering bases. Sorry guys thanks for keeping things on track.

Hey Mark. Do u think this problem could be related to a feed adjustment. If the head is clean. Maybe running thru the adjustment program could reveal more on this? Since it has more diagnostics than the Epson driver has.

We have this happen all the time with our T-2, and 99% of the time it's the magenta or the white that will start banding after 20 or so prints, in our case if I shut the printer off and look at the bottom of the print head there will be a spot of magenta or white on the bottom of the print head that the wiper hasn't removed, a quick swabbing off with a little cleaning solution and we're back in business.

In fact had the same thing happen last night after a couple shirts, the printer had sat off with cleaning solution in the head for a few days, the first two shirts printed great (1440 underbase & 360 color) on the third shirt at the end of the print the magenta started banding, not bad but noticeable, after that shirt I did a ink purge and the other shirts printed fine.

You have to be diligent keeping the seal on the capping station, the wiper, and the area around the nozzles (where the capping station seals) clean, no dried ink.

Hope this helps.

Even if the head is clean on the bottom it still can have clogged nozzles. I have seen that on my machine several times. If you have a perfect nozzle check and are still getting banding, I guess it could be some type of bed feed issue, but I have never had an issue like that on my T-Jet.

The only bed feed issue ever I had was when I had lint on my bed sensor and it caused mis-registration between the underbase and color passes.

Like Jon, I keep everything super clean and my machine sits in a temperature and humidity controlled environment and I still get clogging issues. I don't really have many banding problems, and when it does start to do that it is usually a CMYK color and a quick head clean takes care of it. My biggest problem is white ink clogging in the print head and not being able to unclog it easily.

I was just going on the statement he made that he had a good nozzle check. I believe the adjsutment program has some horizontal alignment settings as well for banding. I know for sure my versacamm does. And the 1800 based machines do. Just a thought. Fast T-Jet Adjustment Program
thats the link to the program if you do not have it. If you are on Win 7 you may have to set compatability to XP Service Pack 2, also somtimes there are comm errors, I found that if you keep trying or unplug then plug in the usb it will get there.

Since the OP has not come back to this thread, we don't know if he has looked at any of our suggestions or if and how he solved his issues.

I just returned from a trip and put on a brand new print head. I also pulled off the capping station and gave it a super clean before putting it back on.

My first print had horizontal black lines about halfway through the print followed by a few ink drops.

I turned the machine off and cleaned the capping station and the underside of the head. I also cleaned the encoder strip.

When I had put the machine back together I checked the tension on my drive belt and it was good. I double checked the wheel and sensor that are under the left cover of the machine, those were fine too (I cleaned the wheel while there).

I am about to double check the drive gear to make sure it is spotless too.

Any suggestions that I might be missing?

Check your printhead ribbon cable and make sure all the connections are pushed in snugly.

A brand new print head might need a bidirectional alignment.

The easy test: try a print in 720 or 1440 non-HS mode. If the horizontal lines go away, you'll know you need to run a bidirectional alignment before you can print in HS mode.
