Clean printheads - where does the ink go?

When you use the "clean printheads" function on a printer like the HP OfficeJet 7130, where does the ink/lubricant used in the cleaning cycle go?

I poked around inside the printer and am baffled where all this ink is going, especially since I've probably pushed 3 or 4 cc's of ink/water through these printheads by now.
Into the service station under where the cartridges rest in the home position. Theres a good size resevoir down there with a sponge in it to absorb the ink however if heavily used like 20,000 copies or more they can start to fill and possibly leak if the machine is not kept level. That's why newer machines like the Epsons and brothers have counters in them and after so many prints or primes the machine errors forcing a service call for part replacement to avoid property damage as the old HP inkjet with large copy counts are famous for. If you print off a self test at the bottom it will tell you your page count. If its 15,000 or more you might want to take it in and have it cleaned out. If a good tech gets it in shop they can remove the service station run it under hot water and really clean them out making them almost look brand new.
