  • Patent number: 4969011
    Abstract: A toner cartridge dispensing system is provided which is particularly useful for xerographically plotting documents of above average length, such as engineering drawings. In one embodiment, a modulated electronic input is scanned across a photoreceptor surface. The electronic input is monitored and data bits are counted to obtain a preview of how much information will be required to be developed. The dispensing cycle is controlled to dispense toner based on this prediction. As another feature, the recognition that the amount of toner dispensed from a toner cartridge lessens with each subsequent cycle results in a compensation by weighting the dispensing rate so that the dispensing cycle frequency is effecting increased by a factor consistent with the total number of dispense cycles already accomplished by the cartridge.
