Well, perhaps for homers but so far it seems not on the commercial side. My refill lady says they are aware of the Epson method and use a reprogrammer to clear the chip in the cartridge. Apparently HP tried chips some time ago but found they were susceptible to just that and have now come up with something more fiendish. She's not exactly sure what. One day when she gets a spare empty one she'll pass it over for dissection. One good thing to come out of being a sticky-beak and engaging in counter chat is that she'll keep an eye out for an HP cartridge I've been looking for. I was given a Deskjet 400 minus cartridge. Great, I thought. Until I found out the replacement cartridge will be $89.95 (robbers !!!! It's a bottle of ink dammit !!). Huh, some gift. If I play my cards right and get her some help with the refilling problem maybe I can score a discount -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
