Question : Bro HL-5140 laser printer: How do I reset toner settings?
My Brother HL-5140 laser printer has toner in the cartridge, but the printer says it needs replacing and refuses to print. So “helpful”–not. Obviously a ploy to sell more toner cartiridges. Are there any work arounds that you know of?

Answer by Ken -
If the toner has a chip/metal contacts on it, they can usually be reset by purchasing a resetting device. Shouldn’t be too expensive, I would look on eBay, but you may be able to find one elsewhere (e.g. google).

Hope this helps,
