You have a bad FUSER unit....expensive!! It is not heating up.

That is a maintanence code. Usually says that the fuser rolls are at a certain copy count.
Here is what to do.
Press in order on the consol. # * C * That will enter the machine into what is called SIM mode.
Then enter the number 24 then 4 for that code, then press execute. You may want to just do the clear all maintenance code too.
