I was thinking also that might be it.
When i make more pictures of the printer i will throw in a syringe -  
hopefully finally tomorrow.


BTW i found my printer has all the cal parameters set to zero (and by far  
not ideal).
Does this mean the guy at epson decided he'd rather have a longer break or  
is it normal that they don't adjust them printers?
