To clean the transfer drum 1 Leave the printer powered on and open the printer’s front door. 2 Push the white button on the lower (green) lever and swing the lever to the right. 3 Open the upper door on the right side of the printer. 4 Using the handles, gently pull out the transfer drum until it stops.

5 Lift the drum out of the printer. 6 Place the drum on a clean, smooth surface that is free of sharp or rough objects. 7 Face the drum surface towards you (the handles will be away from you). 8 Center the print sample beside the transfer drum with the top of the page toward the transfer drum. 9 Using the print sample as a reference, inspect the transfer drum for a small spot or speck that might be causing the repetitive defects. 10 To locate the spot or speck, you might have to rotate the transfer drum by turning the shiny metal area on either side of the transfer drum surface with your fingers. CAUTION Use extreme care when removing a defect from the transfer drum. Using a sharp object to remove the defect or allowing fingernails or jewelry to touch the transfer drum can scratch the drum, causing permanent damage. Do not clean the transfer drum using force. Do not use any water-based cleaners or excessive alcohol. These actions can permanently damage the transfer drum. 11 Gently rub the spot or speck with a hand wipe. 200 8 Solving <strong>Printer</strong> Problems EN
