Re: biz 350 light copies

I've had to increase the toner density in service mode. Also show customer how to manually tone up using the tab "add toner" under "user management". Have them do this once or twice a month. Unless using genuine Drum, developer & toners these machine will run light. I've even had this series with all genuine supplies still run light as they got older. Only a few Biz 250's left. They just won't die!
