The problem I have with toner not included is that the customer will buy any crap they can find to use in your machine. We never leave more that 2 toners for a machine at a time. Every tech holds the responsibility to maintain a relationship with the person responsible for installing the toner and there is an agreed location where spare toners will be stored. When I go into a customer part of the call is to check up on toner and supply from predicted boot stock as needed.
