How do I override the printer when it thinks it

You dont....if it has no toner in any one of the four carts or if the chip hasn't received its reset from a manufactures toner in x number of prints it wont be going for you, even with access to full service software helps me none, must have toner chip, all electronic on these babys, not done via powder levels

oh and these dont use ink, its toner in all laser printers, powder thats arranged on paper with static and melted on with high heat..

p.s. these printers are my least fav and one of most expensive to run, but one can buy them cheap with good warranty and I tell ya.. they need em cause they are always getting fixed/thrown more than any other on the market.

Laser printers generally are great Kyocera are kings, Samsung is the swamp, sorry but best be honest now rather than another toner pack later...cheers
