When the printer display indicates CARTRIDGE LOW, Press the tick image to clear the message and continue printing.
If print appears faded remove the cartridge and shake it side to side before replacing it. This will enable you to obtain the best "yield" from your toner cartridge.
To avoid toner wastage, do not change the toner cartridge(s) until “Replace
Cartridge “message appears and the printer refuses to print.
