We get a complete black page.!!
Fist we thought it was the toner and changed 3 diferent cartridges, but still the same thing.
We have no clue where to start....I suspect it has to do with no good conection or something like that. No electricity is going through, BUT we realy do not know.
HOPE SOMEONE CAN HELP US WITH THIS.

Re: COMPLETE BLACK PAGE
Not sure but I think this model has a separate drum unit try replacing the drum unit if this still doesn't work then the laser unit has a fault also you could try vacuuming out the inside of the machine as maybe caused by loose toner on the contacts.

I think the ribbon or printer head need to be change since it prints a complete black page, if it is a blank page it prints, i would have said the toner ink is low in the cartridge or finished but since it is a black page it needs replacement.
