INSTALLATION PROCEDURE [A] [C] Installation [D] [B] [E] B435I508.WMF NOTE: If the fusing temperature is lower than 60°C when the main switch is turned on, the main motor must rotate to generate a triboelectric charge on the developer and toner. However, to prevent damage to the hot roller, the main motor will wait until the hot roller's temperature reaches 80°C before rotating. This may take a few minutes. In this case, it is not necessary to use the SP mode to load the developer. Skip steps 13 to 16. After the developer is loaded from the development entrance, turn off the main switch to stop the main motor. Pour in the second 1 kg of developer. 13. To begin main motor rotation, enter the SP INPUT/OUTPUT mode by pressing the following keys on the operation panel: Clear Mode key [A] + key [B] + key [B] Clear/Stop key [C] Clear/Stop key [C] again and hold for at least 3 seconds. 14. After 3 seconds, the wrench and toner end indicators will blink (SP INPUT/OUTPUT mode). 15. Use the + and - keys [D] to select 23, then press the RF Select key [E]. The main motor will begin rotating. 16. Press the RF Select key to stop the main motor once the developer is loaded from the development entrance. Pour in the second 1 kg of developer into the development unit evenly across its width (Total: 2 kg). Press the Clear Modes/Stand by key 3 times to leave the SP mode. SM 3-9 B047/B048
