I’m not sure where Mr. Le is getting his info but here is what I can tell you from my experience.
I purchased a 4800 a few years ago and it started clogging after about 9 months. It was so bad that I could not fix it, and I tried all the tricks. It needed to go into the shop to be fixed.
I have had my 3880 for over a year and have let it set for over a month with zero clogs.
Before buying my 3880 I was considering the new 4900 to see if Epson had changed over to a pressurized ink delivery system. I looked for specs on line, here is the link, and did not see it. So I called Epson technical support (Repair Center) plus I contacted the local Epson sales rep. They both confirmed that the 4800-4900 have a non-pressurized gravity fed system.
Here are the specsoff the Epson site on the 7900, which you will find for all their printers EXCEPT the 4900.
“Epson Intelligent High-Capacity Ink System
Pressurized ink cartridge technology ensures reliable ink delivery at all print speeds, while dramatically reducing the physical size of the ink cartridges.”
So I offer here;
#1 My personal experience in owning one.
#2 Epson specs in writing.
#3 Epson Sales Rep confirmation.
#4 Epson Service Tech confirmation.
