Description
ATC Sensor Fail The frequency at which the ATC Average Fail or the ATC Amplitude Fail has been occurring is at the threshold value or higher. NOTE: To clear this Fail, clear the value of NVM [752-059] (ATC Fail) or NVM [752-060] (ATC Fail Continuous Count) to '0'. If the machine is not repaired back to normal status, this Fail will occur again during the operation. NOTE: Setting the NVM [752-005] (Dispense Mode) to '0' (Timer Disp) or '2' (ICDC Disp) will prevent ATC related fail from occurring and enable you to use the M/C. However, this means that the Toner density will not be controlled.
Remedy
1. Install a Toner Cartridge that contains Toner. Copy a Test Chart (499T 00247), etc. and check whether the density has recovered. 2. Check the Toner Dispense Motor (Output Check [092-001]) for operation failure. (PL 8.2) 3. Check the Toner transport path for Toner blockage. 4. Check the connection between the ATC Sensor (Drum Cartridge) P615 and the ESS/ MCU PWB J409 for open circuit, short circuit, and poor contact. 5. Check for toner blockage within the Developer Unit. 6. If no problem is found, replace the following parts in sequence: • Drum Cartridge (PL 8.1) • ESS/MCU PWB (PL 18.1)
Раз вы говорите, что драм убитый и едет новый, а пункт номер 6 предлагает его поменять, то следует его должаться.
Пока ждёте, можно поразвлекаться передёргиванием шлейфов, как предлагается в предыдущих пунктах)
