The lamp turns on for one second. To check movement of the mirror assemblies, press SC-MOVE. Mirror assemblies move at 25% increments and then return to "home" positions in sequence when you press OK: operation HP -> A is checked the first time you press OK operation HP -> B is checked when you press OK the second time operation HP -> C is checked when you press OK the third time operation HP -> D is checked when you press OK the fourth time Adjust the intensity of light of a new scanning lamp. Press LAMP-ADJ and then press OK to turn on the scanning lamp. When the scanning lamp replacement VR is turned slowly, an audible beep is emitted when the optimum intensity is reached. Press OK in response to the beep to save the intensity setting and quit adjustment. CAUTION: Wait until the intensity of the lamp has stabilized (approximately five minutes) before adjusting it. Adjust the intensity of the lamp after removing and remounting the lamp, or when replacing the reader controller PCB or the light intensity detection PCB. Press USE-LAMP and then press OK to turn on the scanning lamp. When the scanning lamp replacement VR is turned slowly, an audible beep is emitted when the optimum intensity is reached. Press OK in response to the beep to save the intensity setting and quit adjustment. CAUTION: Wait until the intensity of the lamp has stabilized (approximately five minutes) before adjusting it. To run self-diagnosis on the AP-IP PCB, press IP-CHK and then press OK. When self-diagnosis ends, "OK" or "NG" appears to the right of "IP-CHK." To check operation of the auto power-off mechanism, press POWEROFF, press the OK key, and then turn off and then on the power to start the mechanism. To drive the developing rotary and the sleeve motor for approximately 25 seconds, press DEV-DRV, press the OK key, and then turn off and then on the power to start the mechanism. Run paper feeding test. Select the source of paper (cassette 1 or 2, multifeeder) and mode of delivery (face-up, face-down) in user mode. Press PPR-FEED, press the OK key, and then turn off and then on the power to start the mechanism. Drive the intermediate transfer drum and the photosensitive drum for approximately ten seconds. Press MAIN-DRV, press the OK key, and then turn off and then on the power to start the mechanism. Save data stored in EEPROM on the ECO-2 PCB to the RAM on the reader controller PCB when replacing the ECO-2 PCB. For more information, see "Copier, run/check mode, MISC-P > DC-SAVE/DCLOAD details" on page 97. Load data unique to the ECO-2 PCB (and saved in RAM on the reader controller PCB) to EEPROM on the ECO-2 PCB after replacing the ECO-2 PCB. For more information, see "Copier, run/ check mode, MISC-P > DC-SAVE/DC-LOAD details" on page 97. EN 95
