Digital BW, The Print

Hi
I have followed the mailings in this group for a couple of years now, 
and it has been a great help..... Thanks to you ALL.
Now to my question, two weeks ago, when I changed a roll of canvas on 
my Epson Pro 7500, the printer made a noise and started to flash all 
the lights in the panel. The error code I got is "SERVICE REQ. 
00010004".
After trying to reset and...... finaly I contacted Epson here in 
Sweden, but without geting any help or explaining the error code. 
Has anyone seen this error message before? What can be done about this?

I´m most greatful for any help.
Josef
