I just thought I would update this thread to give some experiences, since I originally posted in it looking for advice. Long story short, I have had a very rough time with this printer. There are some positive aspects like what appear to be blacker blacks, particularly in matte prints, and of course the lack of ink switching is extremely useful. But that is about all I can say is good. I have had constant struggles with banding, almost no help from Epson at all, tons of wasted paper, rolls being torn off the core and just a bunch of assorted glitches, hang ups and time wasters (for example, deciding to run a cleaning after a print and making you wait for the cleaning before it will eject the print). The paper loading and handling is extremely tedious, even if you turn off the skew detection. I was printing a large exhibition of very dark black photos and it took me several days to tune out the banding, which involved far more than one might expect or at least what I was used to in the P9000. The most recent problem I am having is that it keeps jamming and creasing very thin papers. For example I have a 90gsm matte proofing paper that I use just for tests, and it will not even load...it just advances into the printer and crumples every time. I am currently doing an exhibition on Murakumo Kozo Select 45gsm, which is admittedly an extremely thin paper, but I used it with no issues at all on the P9000. Now it is starting to crease the paper vertically...I guess between the vacuum nozzles. I have reduced the vacuum to -4 and have the roll tension on high and it still happens. These prints are 180cm long, and it is often not starting to crease until 120cm or so, so it is really adding up in terms of lost materials. If I could wave a magic wand and just have a P9000 again, I would absolutely do it. My experience with the 9900 was also very negative with lots of problems, so I think it is clear that Epson uses their users to beta test these printers. I hope they introduce a better model soon, because this thing is truly a terrible business partner. I am shocked it got out the door, not just for the technical issues, but because of the extremely inefficient usage...the amount of steps involved just to load a single sheet of paper is ridiculous, or the fact that you cannot multitask at all. For example, if you turn on the printer and open the cover to put a roll in, the printer will stop booting up, tell you to close the cover and not do anything until you do. Why not just continue booting up and let me do my work? Sorry for all the gripes, but I am at my wits end. I have had this printer since 2020 or so and it has been a bummer the whole time. I have been running a Certified Studio since 2009 (well, certified in 2015, but the same studio), so it is not like I am a noob who doesn't know how to fix typical issues...
