Title: You can refurbish an ink tank
Review: The ink tank for the 4800/7800/9800 is a simple plastic box filled with paper absorbent. Thirty five bucks is way too much to pay for such a simple device. You can "refurbish" the tank with a roll of toilet paper. Remove the lid from the tank, remove the cardboard tube in the center of the roll and cut the toilet tissue in half with a bread knife. The two halves will just about fill the box to recreate the absorbent. Here's the kicker. The printer reads a chip on the tank and remembers the last two tanks, and maybe more. It will not let you reinsert and reuse a recently used tank even if it has been "refurbished". If you have a buddy with the same printer you can switch refurbished tanks to fool the printer.
