3.8 Sensor Operational Check Function This function allows you to check whether the seven sensors (document front sensor, document rear sensor, cover sensor, registration sensor, paper ejection sensor, toner sensor, and hook switch sensor*) operate correctly. (*The FAX8060P/MFC9060 has no hook switch sensor.) In the FAX-8060P/MFC9060, the LCD shows the "FRRECVRGHATN" when - the document front sensor detects no paper (FR), - the document rear sensor detects no paper (RE), - the top cover is closed (CV), - the registration sensor detects no paper (RG), - the paper ejection sensor detects no paper (HA), and - the toner sensor detects toner (TN). In other models, the LCD shows the "FRRECVRGHATNHK" when - the document front sensor detects no paper (FR), - the document rear sensor detects no paper (RE), - the top cover is closed (CV), - the registration sensor detects no paper (RG), - the paper ejection sensor detects no paper (HA), - the toner sensor detects toner (TN), and - the hook switch sensor detects the on-hook state (HK). Operating Procedure (1) Press the 3 and 2 keys in this order in the initial stage of the maintenance mode. The equipment sounds 1100 Hz and 400 Hz tones cyclically through the following volumes for testing the speaker. In the FAX8060P/MFC9060, the LCD should show "FRRECVRGHATN" if the detecting conditions of the six sensors are as defined above. In other models, LCD should show "FRRECVRGHATNHK" if the detecting conditions of the seven sensors are as defined above. (2) Change the detecting conditions (e.g., insert paper through the document sensors or the registration sensor, or the top cover, jam paper at the paper outlet, remove the toner cartridge, and lift up the handset), and then check that the indication on the LCD changes according to the sensor states. (3) To stop this operation and return the equipment to the initial maintenance mode, press the Stop key. V - 54
