Sounds like the dreaded "whirr-bang" syndrome closing in...
First, I assume you've done all the align heads option in the epson tools, clean print heads, etc.
Try this:
Turn off Printer
Press Paper Load button
Hold it down
Press Power button
wait for power light to flash green
release paper button
It should print a test sheet. It also seems to fix the whirr-bang, at least temporarily.
If that doesn't work, search this forum for my user name, I listed a long list of things to try that I don't want to retype.
