I am encountering what I have learned is a common problem with the 3800.
Using mine to make editioned fine art prints of drawings/paintings on 17 x 22 sheets of Hahnemule Photo Rag 308gsm, I am getting bits of black ink on the corners of the paper that render the prints worthless.
The art is all black (using abw mode), with a lot of white space on all sides. Therefore, the corner black marks on my prints are even more infuriating than they might otherwise be. In some cases, I can gently shave it away, with a razor blade, but in other cases, no.
I am using the trick of bending the corners back a bit before loading the sheet, and that sometimes works.
I can't in good conscience get in to arbitrarily trimming prints down from their advertised sizes. Trimming also makes the continuity of presentation more challenging.
Wasting sheets is expensive, time-consuming and frustrating as hell.
A fine-art photographer friend of mine showed me the bend-the-corner workaround — his gallery had complained about certain messed-up edges he wasn't able to hide — and also told me that when he inquired directly with Epson, they "wouldn't really go there." Hmm.
Has anyone found a RELIABLE workaround to this problem? I'm not looking for "I've never had this problem" responses. It exists, and I really do need the help of someone who has experienced it, and has figured out a way to deal with it.
Your help is appreciated.
