I can understand how this would be successful in filling a black cartridge. But how can this work properly in color? The problem that I envision is that the colors would be contaminated by one another due to the close proximity at the head itself. How is success achieved in light of this issue? Or does the technique only work with black?

I've found, also, a different device included in some InkTec kits: their "Wonderful Suction Device," said to eliminate air pockets. Does anyone have experience with this? How does it work?

The only Inktec refill kits I have experience with are for the HP 56 and 57 carts. These fill from the top, but there is a snap-on holder where you connect a syringe to draw (suction?) a small amount of ink through the print head to eliminate any possible air blocks.

I did have another brand of kit, "Inkman," for my old Deskjet 500 that filled from the bottom. At first glance I thought it filled through the print head, but I soon learned that it filled through a vent valve passage in the bottom. This printer was black-only. The Inkman kit also had a "wonderful suction device" that was used to set the pressure balance in the cart. This was applied to the vent on the top.

I had much more success with the Inkman kit than I did with the kits that required you to drill a fill hole in the top and plug it when done. BTW, the hardware from the Deskjet 500 kit also fit and worked with the black carts from the Deskjet 600 series printers. They used different ink, but the holder and suction device were a perfect fit.
