I've had a Brother HL-2230 for a short while.  I used up all of the toner & the light turned on, so I bought a new (not original) toner cartridge.  I swap out the cartridge & the light remains, so I also buy an imaging drum.  Swap that out & the light remains.
Looking at the software, it knows when the printer is on/off, open/closed or on standby. But I can't get it to turn off that light & just let me print! Does anyone know what I've missed?
