Default Epson DTG F2100 - Yellow Ink Nozzle Check Poor

Hello Everyone,

The Epson F2100 is my first DTG printer. I've had it for several months now but it seems that the yellow ink continuously has problems which can be seen in the nozzle checks. All other colors comes out perfectly during the nozzle check.

A technician has come by twice already to change the printhead and the duct assembly but this issue still persists even the next day. Yellow will print but it will lose more and more nozzles with every passing day or two. I am at a lost and was wondering if anyone else had come across this issue.

I tried to attach an image but do not know where to do so.

Thank you in advance for any thoughts or suggestions.

Well, that isn't good at all.

I might ruffle a few Epson feathers here but if it was my machine I'd be raising hell on the phone with Epson Tech support.

That DTG is under warranty and I would not stop pitching a fit about it until it is printing properly.

I myself have had a complete DoDo bird or two on the other line at Epson Tech at at times and at other times I have what I thought were great people who knew my Epson printer very well. Luck of the draw I guess.

I had an "Epson trained" tech come to my shop to repair my warrantied F2000 in year three of a $1,9000 extended warranty. He wasn't very friendly at all, he looked like a hobo from homeless alley and a month later I had to call Epson to fix the same problem again and sure enough that same guy showed up at my place to fix my machine.

Yep, you guessed it. Another month later I was back on the phone with Epson again. I was pretty pissed. I told them not to EVER send that guy to my shop again. The next day after a phone call from a different tech at a different Epson trained company he showed up at my door, fixed my machine and it hasn't skipped a beat since. That guy was great. If I could remember his name I would give him a BIG shout out right now.

The first guy also burned though $400 of MY white ink too. Took me about 5 phone calls with Epson and the company that he worked for to ever get that ink back.

...just sayin'.

sometimes, after a damper change, it tooks a while in order to have a constant perfect nozzles check.
It also matter if the procedure is fully performed or some parts are skipped. For example I usually skip the depressurising before the change and the charge after the changing. In this way you need to perform some additional cleaning, but you wast less ink.

In any case, assuming that all was done right, are you able to recover the yellow nozzles or even after several clean they don't came back?
If you recover the nozzles and then they slowly dissapear, probably the head is ok.
How are humidity and temperature of the ambient? How many prints do you have done after the head change and in how many days?

GatorGrafox -- sorry to hear about your bad experience. Luckily the technician who came was an Epson guy and it seemed like he knew what he was doing.

Amelion --from my observation, the technician used the Epson Adjustment tool for the F2100. I did ask what he was doing along each step of the way. First he used the program to depressurize the ink lines, changed the printhead, changed the duct assembly (damper set), used the program to charge the ink lines again. He performed a nozzle check and all colors came out great with no breaks. The first time, only the printhead was changed and all nozzles fired just fine like this second time around. The following 2-3 days, yellow came out just fine but after a couple more days, you can visibly see that there were dropped nozzles for yellow--15%, then 25%, now barely 50% nozzles for this particular color appear during the nozzle check. Strangely, Cyan, Magenta, Black, AND ALL WHITE nozzles are firing 100% with no problems at all.

Performing a medium clean brings back only a few extra nozzles but nothing more than that. I did think that it was the temperature of the room as well but wouldn't all the colors be affected, especially the white? Being here in Southeast Asia, the humidity is pretty high and the room temperature is a bit warm (30 degrees Celsius). I turn on the A/C 15-30 mins prior to using the F2100 though. The rest of the day, I have the doors opened and the windows opened because I am printing adhesive stickers with an eco solvent printer. I print between 5-15 tshirts a day but nothing much because I am afraid to accept orders especially with the yellow acting all strange.

I can't seem to figure out why only this color is giving me problems. I am using the original Epson ink cartridges and have changed to a new cartridge just to be safe after the new duct assy and printhead but there are still issues. I'm now wondering if there's a backflow for the yellow--but why not the other colors as well?

Once again, I tried to figure out how to upload an image by reading through the "Need to Upload an Image?" link but unfortunately I do not see the Manage Attachments under my Additional Options nor do I see a Go Advanced button.

Thank you for any suggestions.
