Aligning printing heads (Epson)

I've been playing with my Epson SX130 and it seems that the heads have got disaligned. I am using debian and find no tool to align them in cups web interface. The only tools related to that are mtink and escputil. As to the former, it does nothing but hanging.

When I try (it should print a nozzle check pattern):

escputil -n --raw-device /dev/usb/lp0

It answers:

Unknown printer Epson Stylus SX130!
Running nozzle check, please ensure paper is in the printer.

But prints nothing. I retry, it starts feeding paper and stops, getting this message:

Cannot write to /dev/usb/lp0: Recurso no disponible temporalmente

Trying this (it should align the nozzles):

escputil -a --raw-device /dev/usb/lp0

It answers:

Unknown printer Epson Stylus SX130!

Do you know a way of aligning this printer's printing heads within Linux?

Thanks for your help.
