We all know and have been told the importance of keeping ink flowing but I just wanted to reiterate the importance of doing this.
My system runs the artainium ink from sawgrass and when I first started in this I knew just how expensive the ink was so I was a little dubious of running a test print as I didn't want to 'waste' ink - a major error!
By not keeping the ink flowing you will 'probably' cause some sort of blockage which 'could' result in numerous head cleans - and the ink used in these head cleans is so much more than doing an actual test print.
So, since December I make sure that I run a print through my system at least every 48hrs - this may be too much but it works for me and to date I have had NO PROBLEMS and my ink seems to be lasting longer as I have avoided numerous head-cleans!
I run this through my b1100 (a 4 colour print as the b1100 is a 4 ink system):

and I always get a clear print (print out may look faded as I'm printing with my profile onto plain paper):

So, a little investment in preparation and looking after your equipment will help in the long-run
