Frequently Asked Questions


Why is it a bad idea to leave empty toner cartridges inside the cartridge tray of my Brother HL-4150cdn?

Leaving empty toner cartridges inside the printer is discouraged because this affects your printer’s performance once the new cartridges are in. Plus, there may still be remaining toner powder that can stain the cartridge tray, making it difficult to clean.


How would I know which cartridge needs replacement?

On your machine’s display, you will notice black square and white square marks that indicate the status of each cartridge. See which cartridge needs replacement checking the white square.


Can I still use my Brother HL-4150cdn even if I get a white square indicator?

Yes, as long as the print quality is still good.
