It's not asking for just paper, it is asking for a specific paper. It will also have a fault code that can tell you more.

As for the cause, it could be that the driver is using normal settings, but someone put in the paper at the printer and set it to cardstock, in which case you would need to change the paper type at the machine back to plain (if that is whats loaded) or set the driver to print on cardstock instead of plain.

I'm trying to print a single freaking page, ONE PAGE , and it keep's telling me "please load paper then press OK". i literally fed any amount of paper i can shove up those two slots and it still gives me the beep...
i've reinstalled the software, changed everything to A4 (pdf,office,printer software,etc)
except for factory reseting the printer which i cant find how.
If i wont find a solution on these forums i'll literally take it to work and smash it with a sledge hammer.
