Just a guess, since I'm not sure this is the problem. On the printer Control Panel, make sure "Paper Size Check" is turned ON. I rather doubt it would be anything that simple, but sometimes missing the simple things can cause a lot of issues.
Larry - The solution you discovered through Epson seems rather drastic. However, it's been many years since I worked with a 4000, so that probably refers to the maximum length the printer could handle on roll
paper I assume. Since I never used roll on the 4000 I would never have encountered that problem. However, in Kees situation the maximum length issue would have no bearing, since he's working with sheet sizes. I also
agree with Phil's request, referring to the total res of the image file being sent to the printer. That can certainly cause negative results in some cases, although I'm not at all familiar with the limitations of the
printer he is working with.
