This question is for the general user with a small to large print shop that has used PiezoFlush with a 3880 or x890. Have you had a clog that in a channel that you haven’t been able to clear and resulting you trying Piezoflush? Has this attempt with Piezoflush worked for you.
A bit of insight with my problem. In the past couple of years I have went through five 3880 printers, with the clogs always being in Magenta or Yellow. I was using ConeColor Pro K3V with all said printers. Four out of the five models were Epson OEM refurbished. I tell you that because it could possibly play into the fact that these printers had problems from the day I received them and just took a little time before it came out. That said it could also be the inks due to this next bit of experience from my side.
I had a Epson 9890 from late 2012 till early 2015 (it was two years and a couple months old) bought brand new, that used only ConeColor Pro inks. The Light Cyan went, but I was able to get it back for a short period (about a month), but finally it became a 75" 200lb paper weight. Move onto the 7890 I decided to replace it with (bought brand new). Same set up with the inks from ColorColor Pro. It was a full year that I had it and once that full year hit, the Magenta clogged. I didn’t even bother with trying Piezoflush because it was still under warranty. They replaced the “capping station” and print head, worked great! Fast forward another year, same problem, same color. In between all of this those five 3880 were having problems in the Magenta and Yellow, same inks I was using on my 7890 and 9890. Well after this most recent head replacement on our 7890 I decided I can’t keep using ConeColor Pro inks and just went for Epson inks in our 24" machines (one because they’re more costly to replace and two I can’t get a warranty extended past a third year)
After giving you a little insight to the build up of my problem, I had a 3880 replaced back in October (I have two, and both were replaced, due to the same issues, Magenta and Yellow just wouldn’t come back). Already the first one that was replaced in October, the Yellow dropped out. Not sign of it coming back. I flushed Piezoflush through the lines and still haven’t been able to get it back. I have followed said instructions with no luck. As stated, I would like to hear from other customers if it has worked for them.
I know there is no guarantee, I’m not here to bash Inkjet Mall, or post a passive thread that I’m not using their ink with our pro line of printers anymore. Inkjet Mall has been more than helpful and when I inquired about said problems in the past, were quick to respond and more than willing to help out (they replaced said carts I had problems with in the past, and never questioned if it was a user error, asked about ink and how old it was). I might just be having horrible luck with said printers. Just bought a whole bunch of lemons, but since it was a little to much of a coincidence with the same colors of ink from the same bottles, I couldn’t keep making that same expensive mistake.
Last thing, the ink I used would never sit around long and was always used up within a couple months. The machines run daily.
Thanks in advance.
