Got mine in June 2021 and within a few months, it wouldn't take more than a sheet or two of luster and always scratched my Exhibition Fiber... After Epson suggested using the front feed and I couldn't get the tray to deploy, Epson replaced it with a refurbished P900.
That lasted about a year. It worked better than the first and didn't scratch the Exhibition Fiber any more, after a year it started having feeding problems, this time pulling several sheets of Prem. Luster before spitting ink blobs on the margin. It finally bricked...
So I went to Craigs List and found a second-hand, low milage 3880. It had the notorious black ink valve issue which dropped the price considerably... It went to my printer guru to be rehabbed and in a little over a week, I was back printing with a nearly like-new machine, twice the weight and much larger than the P900 but with no issues!
IMO, for all practical purposes, PK on mat paper is no big deal and I just keep printing along, this time with no worries that the this printer will crap out after a few months. I just wish I hadn't stocked up on ink for my P900.
I wish I would have purchased a P800 but I had access to another 3880 that had been refurbished a couple of times. That printer got refurbed for the 3rd time a couple of years ago and may last another 2-3 years before it gives up the ghost; maybe more. It's been in the family since 2011 and keeps going.
In the mean time, my second-hand 9900 that I purchased in early 2011, keeps going and going. I've had it serviced once and the head replaced with the updated part a few years ago and it's doing well. For now I'll wait and see how that 5370 does for a few years and if I ware out the 3880 or need to get another production machine, it certainly looks like it will do. If it's built on the heritage of the 4000 I had 20 years ago, that 5370 will go for years.
