Default Nozzle pressure problem

Hi everybody,

Still full of problems with my printer. I came back few days ago from my service guy. He changed our printer head and put new ink (Image Armor).

We didn't have time to stay 2 days at his place, so i decided to make test at our workshop. Nozzle check was 95 % when we came back from his place. Next day it was a disaster. Nozzle Check 30 % maybe - whites totaly sharpened, yellow dissapeared.

Guy told us to make 5-10 cleanings. We did. Then nozzle check were good for a moment. We made few prints, after that problem has shown again. He told us to make power cleaning.

After power cleaning it was better for 20 prints. Then problem came back. After printing there is big problem with nozzle check.

When he gave up, he said it is my fault because i was suppose to stay at his place for few days and wait for tests. It appears we have problem with nozzle pressure. I paid him 1000 Euro for inks, print head and 120 euro for service. After that i have non working machine.

He assumed that problem is in dampers. What i should do ? Again put machine into my car and travel 500 miles ?

What do you think ?

Cześć

Did you have problems before putting IA ink?

Did your service guy flushed out the old ink with IA solution before he charged new ink?

Check out the "new IA ink" thread and be aware that white from IA settles faster than other white dtg inks (which means that you need to do more maintenance: cartridge and shelf ink shaking, doin cleans).

If you want to save some money, try to change dampers yourself. I don't know how it's about your printer but I've got another dtg machine and it's pretty easy to change whole ink assembly if you know what you're doing.

One more thing: when replacing the printhead for a new one, always replace ink assembly, just for peace of mind.

It seems to me that you have air entering the ink system and I would think it is either the connectors holding the ink tubes together or the dampers.

I would personally be checking all the connectors and replacing the dampers.

Plus the IA 'settling' is not a problem with the R-Jet because of the auto circulation.

Sorry to hear you are having problems, if the dealer you purchased this from is not supporting you correctly please contact me directly.

Who recommended you change to another brand of ink.

Regards.

We decided to change it. Mostly because of curing time. Dupont 2.5 Minute, Image Armor 35 s. That makes a huge difference.

We sent printer again to the supplier. Now he are making tests. I hope this is something small and problem will dissapear.
