Solution
If this warning message appears on the printer home screen, continue to use the toner cartridge as normal.
Refer to KB topic Understanding a ‘Toner Low’ message.
Explanation
While rare, early toner low warnings can occur and will not affect the ability of the toner cartridge to print the full number of pages.
