Never ever buy a brother laser printer.
These printers will lock down when it “thinks” it’s out of toner and “force” you to replace the cartridge that has plenty of toner left.
Just turn “continue mode” on. It’s nothing secretive either; Brother cites this in their own FAQ for any model this pertains to.
I have several other brother laser printers
They are awesome and very economical to use.
Hope this one lives up to my expectations too.
