R200; New Carts, dumb nub question!!!

[milkmonitor]

Hi all, I have just replaced all 6 cartridges in my Epson R200 with third
party "Platinum" branded cartridges and am getting no ink on the paper at
all.
Apparently there is an air vent sticker that I have forgotten to remove
but now the cartridges are installed I can't find a way to get the print
head into the right position to get them out again! Any one any Ideas???
TIA

With the printer powered on and in a ready state, press the ink button (the
leftmost button as you're facing the rpinter).
