HP 2840 Drum Hack


Ok, discovered this when my drum went down before the replacement had arrived. No need to buy the after market chips from Amazon or elsewhere, just pry the chip off of one of your old toner cartridges and swap it out with your Imaging Drum chip. Printer will initialize and report "Non-HP Supply in Use" but you'll be in business. Not sure if it will work in reverse with toner cartridges but I'll try when it happens. Good luck!
