If printing was interrupted because toner ran out, it will automatically resume when you replace the toner cartridge.
Even if cyan, magenta, or yellow toner runs out, you can continue to print in black and white as long as black toner remains, but the printing quality will drop. If you want to continue printing in black and white, do not replace the toner cartridge until printing is complete.
If the color and density of printing differ after replacing the toner cartridge, perform adjustment.
