Abstract:
A method for detecting a level of toner powder in a printer, comprising the steps of:providing a photosensor;sampling information from said photosensor as to a level of toner powder in a toner container for said printer within a period of time;when sampling information from said photosensor indicates the level of the toner powder in said toner container as being low, changing a counter value of a counter in accordance with a first algorithm;when sampling information from said photosensor indicates the level of the toner powder in said toner container as being high, changing the counter value of the counter in accordance with a second algorithm different from the first algorithm;comparing the counter value with a predetermined reference value; anddisplaying an indication of the level of the toner powder in said toner container for the printer on a display device dependent upon a comparison of said counter value with said predetermined reference value in said comparing step.
