Probable Cause • Document loading error (1) The document rear sensor detects no leading edge of a document within 10 seconds from the start of document loading operation. (The document rear sensor stays OFF even after the document has been fed when the document front sensor was ON.) (2) The loaded document is too short. (Since the document is shorter than the distance between the document front and rear sensors, the document front sensor is turned OFF before the document rear sensor is turned ON.) No drum unit is loaded. Even after paper pick-up operation, the registration sensor does not detect paper. The registration sensor detects that paper shorter than the specified length has been fed. (This message appears only when a received message is printed.) In the scanning compensation data list printed by the maintenance-mode function code 05, less than fifty percent of the white level data is faulty. (This message may appear only in the maintenance mode.) The controller, which monitors the internal resistance of toner thermistor, has detected that the toner temperature exceeded the specified level. If temperature exceeds the preset level, recording is no longer possible. If the toner temperature drops, the equipment will be automatically recovered from the error state. The scanner open sensor detects that the scanner unit is not closed. The document tray open sensor detects that the document tray is not closed when the ADF is feeding or ejecting a document(s). 6-2
