How Often Do You Have to Replace Toner in Laser Printer?

The cartridge generally has a shelf life of 2 years. Further, many models of laser printers allow you to print up to 2,000 pages on a single toner cartridge. 

After that time, the page capacity may be reduced due to lower remaining toner levels. When necessary, a low toner message will appear on your printer screen to replace the cartridge.

The answer is yes, at least a certain number of times. But there are some important caveats to watch out for since repairing printers is not everyone’s cup of tea.

Generally, laser printers use either 1 or 4 toner cartridges. Monochrome printers require a single cartridge to work.
