Check printed pages, page counter, and display messages regularly. If the

printer has nearly run out of toner or the toner is not evenly distributed inside the cartridge.

cartridges from left to right.

Although you can print up to 300 additional pages (at 5% coverage) after the Toner Low message first 
appears, be sure to replace the toner cartridge with a new one before it becomes completely empty. When 
this occurs, the 

o

 indicator on the LCD will disappear.
