I just installed my Selenium K7 inks and tried a nozzle check. I probably shook the bottles a little too much and introduced air into the ink. I did 2 cleans then a nozzle check. I had missing nozzles in shades 2, 3, 4, and 1. I did another head clean which improved things and I was missing nozzles in shades 4 and 1 only. I decided to leave the printer for a few hours (about 5 hours). Then I performed an ink charge cycle using the WIC reset tool, did as head clean, and I’m still missing nozzles in shades 4 and 1, but also 6 and 7. I have piezoflush in the GO position.
When I put my R2000 to bed a month ago, I had a perfect nozzle check with both OEM inks, and also with piezoflush carts installed. Carts are from inkOwl.
I just replaced the carts with piezoflush carts again. I’ve got perfect nozzle checks on all but the Selenium 4 (orange) position. I have NOTHING coming out in that position! No piezoflush at all in the nozzle check. Help!
I can’t say anything of other carts. We make ours out of a different plastic. They are using very similar molds as others but they use a plastic that can handle our ink + special screens.
Generally though, the R2000s and other small formats will take a few cleanings + waits to settle down with new carts/fills.
At the moment I’m concerned about the orange position with piezoflush carts. After I get that going again, I’ll try the Sel again.
I just removed the orange piezoflush cart, used a priming tip and pulled about 5-10 mL through the cart, refilled the cart, and replaced it back to the printer. The R2000 does an automatic head clean, then I did another nozzle check. The patter is back to normal. Perhaps these carts need priming each time. This will be frustrating. Also, my GO position emptied before I got a low ink.
I have other products from inkOwl, but I’m not sure I can recommend these carts for piezography at the moment. They may be fine for other applications, but I’m surprised I had trouble with piezoflush too.
Yes, I did remove the air vent plugs.
I’m going to try the SEL again, but prime each position before inserting them.
