Fake "Genuine" Epson R800 / R1800 ink carts

The main content of this guide comes from the Photo-I chat forum @ www.photo-i.co.uk. but my own experience prompted me to write the guide.I first noticed the difference when a magenta cart I loaded put a heavy cast on my prints. Having changed this I started to notice a green cast on the prints. Then the print head started to block up. I'm now back to normal as I only now use carts from reputable sources.The main things to look for are:1. The carts feel tighter when fitting to the printer (they tend to be slightly thicker).2. A different font on the label and slight differences to the design and instructions.3. No serial number cut into the blank side of the cart.4. No place of origin in the rectangular box on the blank side.All mine had "Made in China" on the box and were as items 1,2,
