I have an HP Laserjet 8100DN, which is decent workgroup printer with 20,000 page cartridges.
This is a not a color printer, but I could really use the ability to print just with a single color toner.
A quick Google search shows that nobody makes a compatible toner cartridge with anything other than black toner.
I am aware that many companies sell "toner refill kits" in which you squirt toner into an empty cartridge. I have never personally used a refill system.
So, is there any reason you know that it would NOT work to refill my toner cartridge with cyan, yellow, or magenta? Is the toner powder itself one of several varieties that may end up destroying my printer if I use the wrong kind?
