I recently purchased an HL-5450DN laser printer. It takes TN-720 and TN-750 toner cartridges, 3,000 and 8,000 pages. There's also a Brother HL-6180DW printer, that takes TN-720, TN-750 and TN-780 toner cartridges, with the TN-780 being a 12,000 page cartridge. Obviously the TN-780 is the same form factor as the others. Can I use the TN-780 in my HL-5450DN? What will happen if I do? Thanks.
