Clean the scanner scanbars The image that follows is a QR code containing a link to a video to get more information about how to clean and replace a scanbar. You are recommended to clean the scanbars periodically, depending on how often you use the scanner. 1. Turn off the printer using the power key close to the front panel, then also turn off the power switch at the rear and disconnect the power cable. 2. There are two small indented buttons at the front of the scanner. Press them to open the scanner cover. WARNING! Be careful while the scanner lid is open. Your fingers or hand may be trapped or crushed. ENWW Clean the scanner scanbars 109
