Yeah. Im testing out a CISS on right now. Still working out the kinks.
Et8550 CISS preview
I've had no issues with White, Cyan and Black were starting to have a couple missing spots in the Nozzle Check so I put cleaning solution into the ink tanks, shook it a little bit and that cleared them out pretty good. Had trouble getting the solution out the Black cart so I took out the carts. Then I was able to pour the solution out of Black. No issues removing the cleaning solution from the other colors.
This printer is a tank, Its lasted way longer than any of Xp-15000s. I'm sure the quality of the wiper blade and wetcap.
My first and second Xp-15000 the CISS flooded the wetcap station both had fatal codes.
The 3rd Xp-15000 broke during the maintenance process. I didn't use a CISS with this one.
The 4th had clog in the Magenta that I could not fix. I ended up with an error code trying to clear it.
Most of those problems were probably caused my human error. They can probably be avoided if you know what you're doing. Silicone around the wetcap station is a fantastic idea. Someone else mentioned they did the same thing.
I also had issues with the Xp-15000 reading certain films and especially if I was using Acrorip. I fixed this by putting a white piece of paper in front of the film sheet.
The Xp-15000 is probably better for DTF but personally I would still choose the Et-8550.
Low maintenance ( I did pretty much zero maintenance in the first month and no issues with white separating. )
Refilling ink is fast.
The printer has two auto clean functions, regular and powerful printhead cleans.
It has a setting for manually setting your ink levels.
Also its chipless so no having install or buy extra software.
It has the option to install a roller feeder. There's a setting in the printer preferences.
Speed is okay, like 10 mins to print a 13x19 sheet.
My issue with this printer was the sensor not reading certain film sheets. I did the paper trick with this works everytime.
The other was Photoblack channel was printing a yellowish color ( I haven't figured out how to fix this yet.)
