HP deskjet 460 Waste ink tank full
ANSWER : I worked fixing printers for 5 years for Verizon and some of the older printers were notorious for the waste receptacle filling and overflowing with ink. My solution was good old warm water. Remove the waste container and scoop out as much as you can with a small screwdriver, wiping the discard on a paper towel, then just run warm water from the faucet into the container till all the residue is removed. This is just water soluble ink folks, if you want to test it, scoop out a glob and dissolve it in warm water, its easy as pie. I never once bought a new ink discard reservoir. I just cleaned out my mobile 460 printer reservoir by the same method. There are no electrical connections its just all plastic.
