Make sure your paper is positioned against the right side of the feeder and the edge guide is against the left side of the paper. See Load paper.
If you’re printing from a web browser, the pages may not print correctly due to the web page design. Try one of the following:
Use EPSON Web-To-Page software if you’re using Windows XP or 2000 with Internet Explorer 5.5 through version 6 (not necessary with Internet Explorer 7 which has this functionality built-in). This software automatically adjusts web pages to fit your printed page.
Check to see if there is a Printer Friendly Version (or similarly named) icon or link on the web page that you can click on.
Experiment with page setup and paper size, then select Print Preview from the File menu in your application to view the changes.
