I would think for a $3000 printer one wouldn't have to rely on getting free troubleshooting advice online to solve their problems. That's the one aspect about these printers and their owners I can never understand.
First, a small side point. When I look at the Epson printer pricing and then look at the printers themselves, it's hard for me to see how they're making much (or maybe any) money on the printers themselves if all costs are fully allocated. I think Epson views the printers as devices to use up ink, for which the company is extremely well compensated. That doesn't negate your main point, but I'd phrase it that I'd expect Epson to be standing on its corporate head to do anything that gets its customers printing like mad.
On the advisability of bringing an esoteric complaint like the one that started this thread to this forum rather then taking it to Epson support, I'd vote for this forum. Over the years, I have had many -- too many -- dealings with Epson support. (To read about one extended set of conversations, get a cup of coffee, start here
and read the next two posts, then go here
and read the next three posts.) I have found them to be polite and quick to tell me anything that they knew, which did not approach the level of expertise represented here. If these people were true experts, they wouldn't be working phones for a living. I have also found that there are some topics, usually bugs, upon which they are reticent, probably because they have been told to be so.
