Abstract

In a photocopier environment wherein toner is dispensed from a container, means must be provided for alerting the customer that a container is either empty or is otherwise not dispen-sing toner, It is proposed to establish a control circuit within the photocopier for activating a lamp which alerts an operator to the need for replenishing the toner supply. One portion of the circuit serves the low toner concentration and energizes a toner dispenser relay each time the copier goes into a print mode, Another portion of the circuit accepts and accumulates the dispense commands and, upon reaching a threshold value indicative of a pre-determined amount of command duration (using a timer), combines this integrated output with other internal machine operating conditions to activate the toner replenish lamp.
