My Epson 1400 has now been delivered. Just awaiting the MIS UT-14 inks and cartidges. What I didn't order is a 'Bottom Fill Adapter'. I have just read on the MIS site that after filling you pull some ink out from the outlet to avoid trapped air (I appreciate that I should have read the filling instructions before placing my order). I have filled cartridges on my HP B9180 previously without doing this step and have not had any air blockage problems. If I fill the MIS cartridge slowly is there a good chance of avoiding air blockage problems or are these cartridges prone to this problem?

Thanks
