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 [752-036] (ATC Fail) or NVM [752-038] (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 [752-322] (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 (499T247), 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 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: • ATC Sensor (PL 8.6) • Developer Unit (PL 8.4) • Drum Cartridge (PL 8.1) NOTE: After replacing the Drum Cartridge, clear the HFSI [950-807] (Drum Cycle Counter) to '0'. • ESS/MCU PWB (PL 18.3)
Code: 093-312
Description: Toner Dispense Motor Rotation Fail Regardless of low usage of toner from Toner Cartridge, it was detected to be empty.
Remedy: Check the following: • The Toner Cartridge for improper installation • The Toner Dispense Motor (Output Check [092-001]) for operation failure. (PL 8.2) • The Toner transport path for Toner blockage. • The Drive Gear for wear and damage. If no problem is found, replace the following parts in sequence: • Toner Cartridge (PL 8.1) • ESS/MCU PWB (PL 18.3)
Code: 093-400
Description: Toner Near Empty The Toner Cartridge needs to be replaced soon.
Remedy: The Toner Cartridge needs to be replaced soon. Replace the Toner Cartridge as required. (PL 8.1)
Code: 093-406
Description: Toner Pre Near Empty Preparation for replacing the Toner Cartridge is required.
Remedy: The Toner Cartridge needs to be replaced soon. Prepare a new Toner Cartridge. Replace the Toner Cartridge as required. (PL 8.1)
Code: 093-912
Description: Toner Empty The toner must to be replaced as it has ran out.
Remedy: Replace the Toner Cartridge. (PL 8.1)
Code: 093-956
Description: Drum New CRU Installation Fail During the developing powder installation mode after installing the Drum Cartridge, the ATC Measured Value is found to be abnormal. (Seal not removed)
Remedy: 1. Remove the developing powder seal from the Drum Cartridge. 2. If the problem persists after removing the seal, replace the ATC Sensor. (PL 8.6) 3. If the problem persists, replace the Drum Cartridge. (PL 8.1) NOTE: After replacing the Drum Cartridge, clear the HFSI [950-807] (Drum Cycle Counter) to '0'.
Code: 093-959
Description: Drum New CRU Installation Fail Exceeds Thresholding Times The number of developing powder installation mode executions has exceeded the upper limit.
Remedy: Replace it with the correct Drum Cartridge. (PL 8.1) NOTE: After replacing the Drum Cartridge, clear the HFSI [950-807] (Drum Cycle Counter) to '0'.
Code: 116-317
Description: Configuration NG BSD-ON: The device was started up with a run prohibited Controller Firmware.
Remedy: Upgrade the Controller software or contact the Support Department.
