Printer supplies history report shows Unknown status under toner cartridge level

Issue description

When checking the
Printer Supplies History
 report, it is observed that the 'Initial Cartridge Level' and 'Last Known Level' columns show an '
Unknown
' status instead of a percentage value.

Solution

Explanation
When a toner cartridge is either brand new or very low, some of the Lexmark printers are unable to report the cartridge level to the reporting system. The capability to report the cartridge level varies from printer to printer, and you may observe different behaviors for different types of Lexmark devices.
  • The
    Last Known Level
     will report the
    last
     cartridge level received for a toner cartridge. You may continue using the toner cartridge so that its level goes lower, but the reporting system will never show a lower value than the last numeric value received.
  • The
    Initial Cartridge Level
     will report the
    first
     numeric level received for a toner cartridge, which may not be 100% because of this hardware sensor limitation.
