Title: Method and device for determining capacity of printing medium cartridge
Inventor: PHILLIPS QUINTIN T
IPC: G03G15/08
Filed: 2002-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a device with which the capacity of a toner cartridge can be identified and the quantity of remaining toner can be exactly estimated. SOLUTION: The remaining toner based on the assumed initial capacity of the cartridge is estimated by using pixel counting. A toner sensor 30 supplies a signal showing the time when the toner reaches a known level. The estimated remaining toner is compared with the known toner level to determine whether the assumed initial capacity was correct. Such a comparison can be performed when the toner sensor signal is supplied or when the estimated remaining toner falls below the predicted toner low signal level and a toner sensor signal is not supplied. When the assumed initial capacity is not correct, the difference between the estimated toner level and the known level is used for instructing the actual toner capacity of the toner cartridge.  Next, the pixel count is recalibrated by using a look-up table 46 and, concerning the remaining service life of the toner cartridge, the remaining toner is accurately estimated.
