it stated
To view the approximate amount of toner remaining, continually touch the [Home Screen] key ....

Usualy what i did i use toner chip (100%) fix it to toner cartridge then insert to machine, check the amount if 100% then pull out the toner cartridge and replace old chip insert back to the machine, check it will be 75%.

TRY THIS:

Remove toner and check for broken parts on tube, check the connection of toner assy, reconect all connectors on dc controller pcb.

If you removed the toner assy before the error occcured check if all connectors are properly inserted.

On my APPLE the MAC OS driver depicts the toner levels when I check the printer status under the settings and preferences - printers icon - supply levels is an optional choice. I have not found a way to check the levels on an XP system.

Install Smart Panel monitor for the printer and from the software you can check the toner level.
