Question about Brother MFC-L8390CDW

With the Brother MFC-L8390CDW printer it is possible to print using only the black toner when the colour toners are empty, but there are some limitations and steps that need to be followed.

### Black and white print mode
- The printer can be operated in "B&W Print Only" mode when one or more colour toner cartridges are empty. If the colour toner cartridges are empty, the message "B&W Print Only Replace Ink" or "B&W 1-sided Print Only Replace Ink" appears on the touchscreen.

### Steps for black and white printing
- Make sure that the message "B&W Print Only Replace Ink" or "B&W 1-sided Print Only Replace Ink" is displayed on the touchscreen.
- You can then continue the printing process by changing the print settings on your PC or directly on the printer to "Black & White" or "Greyscale".

### Important notes
- The printer stops all printing operations when a colour toner cartridge is removed and the cover is closed. It is necessary to reinsert the empty colour toner cartridges in order to use the black and white print mode.
- There is no special "Eco mode" or similar settings that would reduce the consumption of colour toner when printing in black and white.

These settings allow you to continue printing black documents with the Brother MFC-L8390CDW printer, even if the colour toner cartridges are empty.
