SERVICE BULLETIN Issued by Canon Europa N.V. FAX MODEL: LaserBase MF5630/MF5650 No.: MF5650-002 Date: 27.08.04 SUBJECT: REMEDY FOR CLAIMS ABOUT “CCD UNIT ALWAYS ON” This bulletin describes how to handle claims about “CCD unit always on”. Symptom: The CCD unit will always stay on, even though the machine is in Energy Saving mode. Explanation: The machine operates according to specification. The CCD unit is left on, in order to enable quick restart and high quality copies / scans after recovering from Energy Saving mode. Measure: The CCD unit can be set to switching OFF in Energy Saving mode. Please follow the procedure below. Precaution: If the CCD unit is turned OFF and then turned ON again, it will take about 3 minutes for it to stabilize its light intensity.
