there/s a more stirival change (like the contacts don't line up) I don't
know, but I am told you jsut get blank sheets of paper if you use the
wrong cartridge.

you fill the copier cartridge with printer toner, and then try to use it
in the copier, it produces a very poor quality reverse video image.
