Cannonvictim - Relax! Refilling is a simple task. 1) seal the outlet port 2) open the fill hole in the reservoir 3) refill, leaving a bit of headroom slightly lower than the sponge in the adjacent chamber 4) seal the fill hole 5) open the outlet and let drip until it stops 6) blot against a piece of toweling paper that is on a flat surface 7) seal the outlet and fill holes to store, or put in printer.
Lots of ways to seal the fill hole. I use the stainless steel pan head sheet metal screw/O-ring technique and, after three years of using this technique, had my first poor seal with some leakage into the printhead. Changed the O-ring, cleaned the printhead, and everything was fine. Mikling is right about O-rings. You have to be careful that you don't compress them too tightly or they squeeze out from under the screw head. The one that finally didn't seal was just plain worn out. It had comressed and widened and needed to be replaced. The beauty of this system is that all you need to set up a new cart is a hot paper clip to open a pilot hole and the self tapping sheet metal screw and O-ring. No drills, no taps - just a paper clip and a phillips screw driver. There are other equally valid approaches to creating and sealing the fill hole. The least effective, from what I've read, is any kind of tape. As I recall, Grandad35 uses flat head screws that have a tapered undersurface of the head, The taper seals without an O-ring.
When I started refilling there was very little information on techniques. I read the info from MIS, checked out Neil Slade's treatise, and just did it. Now you have so much information available on this (excellent) Forum that it may seem daunting when you start. After refilling several carts you will develop your own technique.
