This is a common problem and can be resolved locally without actually having to send it anywhere.
If you want a bit more information on what "Service Required" actually means then
this page will help with the background as well as providing the necessary link to a reset utility (via the Quickfind part).
In quick terms what you need is the SSC utility to reset the waste counter and then either get it serviced (ie: the waste pads) changed locally by a service agent in Menorca, or fit an external waste ink tank.
Plenty of resources on the web that explain how to do it either as a DIY or kits you can get that have everything you need.
Hope that helps.
