The used amount isdetermined based on the counter value (See Section 2.16).End of Life: Time when a toner-low error occurs.The number of drum revolutions is counted, on a letter paper length+ continuous-printing paper interval basis. The count of one isperformed every time when one page is passed.End of Life: Time when: (1) the counter value reaches 80K; or (2)the count of 2000 is reached after belt waste toner near full isdetected.The count of one is performed every time when one page ispassed.End of Life: Time when the counter value reaches 80K.The count of one is performed every time when one page ispassed.End of Life (as Guide): Time when the counter value reaches 120K(the time varies depending on operating conditions).ActionPrinting stops, but 500 pages canbe printed after cover open andclose operation.Printing stops, but 20 pages can beprinted after turning the power onagain or after opening and closingthe cover.Printing stops, but 20 pages can beprinted after turning the power onagain or after opening and closingthe cover.Warning (the unit can still be used).None.2.14 Version Read of Units Replaced PeriodicallyThe version of each of the I/D, fuser unit and belt unit which are replaced periodically is determinedwhether it is new or previous according to whether the fuse in it is conducting or out of conduction.When the fuse is conducting, the unit is decided that it is new. The “new” or “previous” judgmentis performed at power-on and at cover-close. The life counter of every new unit is re-set and the“new” or “previous” judging purpose fuse in the unit is cut.2.15 Life Count for Units Replaced PeriodicallyThe life of each of the I/D, fuser unit and belt unit which are replaced periodically is counted asshown in the following table:2.16 Toner Consumption DetectionThe used toner amount is detected by counting the number of dots printed. After toner low isdetected, when the equivalent of 800 pages on A4 and 5% duty is reached, toner-empty occurs.After turning the power on again, or opening and closing the cover, 20 pages can be printed.
