Marc, I know this is a loaded question... Have you come up with a number to amortize the cost of a head relative to the amount of liters of ink pumped through it? .... especially the more "abrasive" titanium dioxide kind. What is a sure sign of a head "beyond saving" and are there warning signs of this.

Other users have posted this before, but I believe this to be the best way to unclog dampers and return them to a like-new state.
Purchase an Ultra-Sonic cleaner. We bought ours for about 30 dollars at Target. Buy some Simple Green, we don't even bother with the expensive cleaning solution anymore. Fill the tank about halfway with Simple Green and Halfway with Distilled water. Use a Syringe to fill the dampers with your simple green / water and place in the ultra sonic cleaner. Ours has settings of 180 280 380 and 480 seconds. After each cycle, take the dampers out and back flush them with warm distilled water and you will see the filters unclog. Repeat cycles until they are perfectly clear.

Doing this fixed several things we had with our Kiosk such as:
* Randomly clogged nozzles. - Nozzle check is horrible but after doing a head clean some nozzles return, but others appear clogged.
* Ink starvation. - Halfway through the print the white ink stops coming out and then appears clogged when doing a nozzle check.
* Bad head cleans. - Nozzle checks come out perfect or O.K. until you do a head clean and then it appears clogged again.


We found this to be the best order to flush the white ink and get it to print well.
1. Flush ink lines with warm distilled water / simple green or cleaning solution. This may take a good hour or so and several bottle refills, but make sure the lines are completely clear.
2. Remove dampers and clean them with the ultrasonic method listed above.
3. Reconnect dampers and refill ink.

Be aware, sometimes after flushing the lines and refilling it you will need to do 2 - 3 test prints and a maybe 2 head cleans afterward to get all the nozzles to check out fine. If you don't do test prints to get the ink really flowing through the machine, it wont matter how many head cleans you do as it will never produce a healthy nozzle check. (When I bought my machine, I went through an entire inkset just doing head cleans to clear the clogged nozzles, but doing test prints seemed to unclog them).

Hope that helps a bit.

On a color only system it has been less than 5 cents with proper care and maintenance. On a system with white it "averages", for me, in the neighborhood of twenty cents. It was higher than that when we first started, but less now that we know about proper maintenance procedures.

I have never been successful at recovering a head that I could not force any cleaning fluid through with a syringe. Usually if I can get any at all to pass through, I can get it functional.

I have never been able to pinpoint when a head is going bad. I have gone through the process of clearing a clogged head, get great full nozzle downward spray, reinstall and never get quality prints. So being clogged is not the only way a head goes bad.

Excellent piece of advice. This is my approach as well. One plus is that it costs less as well.

Just to be sure, are these figures are per liter used/head.... or per "average" print/head?

This is great info! Thanks.

other than the white ink clogging issue, these machines are awesome and dont even compare to the dtg kiosk.

No problems, we've been using the simple green for a few months now, but I know another DTG user who's been using it for almost a year now.
Prior to the Simple Green, I was using windex cut down with water, and warmed up a bit and never ran into any problems.

I usually just run the Simple Green through once until the bottles are empty, then I refill them with distilled water warmed up in the microwave for about 30 seconds and repeat until the lines are clean.

Word of advice, no matter if you use Simple Green or Windex you must always cut it with 50% distilled water, especially the Simple Green since it's full strength can cause the rubber gaskets to swell in the capping station, ink head, and possibly de-laminate the nozzle plate..

Adams right!
