Did you receive any paperwork with your purchase? The answer may be in the booklet that came with your machine. Hope that helps.

Are you sure the belt is off?
To remove the side covers you need to remove the back cover, then the top cover. You will notice a small 'catch' on both sides of the side cover. You need to release to open the sides.

This may be because you have selected to have the scanner skip blank pages in the software, and it is thinking that the page is blank. Try deselecting that option and see what happens... Kris

Canon 6080-7580 & 9080 are notorious for developing lines on scanned images on either front or rear pages. Verify that the shading units are extending properly & have no black debris by opening the transport fully then depressing the green button on the control panel until the shading plates extend (with power on). Lines are also often due to very light scratches on the reading units glass but can also be caused by dust contaminating the reading unit. For this reason it is strongly recommended to NOT use compressed air around the reading units as it tends to blow dust particles into the reading units. Per Canon, the reading units are not field serviceable but can be disassembled if due care is used when removing the CCD assembly from the back of the unit. Cleaning the CCD array with a soft cloth lightly moistened with alcohol will often be enough to fix lines. If the glass has severe scratches, buffing them out with jewelers rouge may work. There are a few entities that will refurbish these reading units as well.

IT could be a problem with the paper sensor. Please clean the sensor in the paper tray, it looks like a 'black dot' . S. Mohan, Chennai, India

The scanner creates a Raster Image and if it is grey or color, the size is big. After a few images are scanned, the 'buffer' inside the scanner is full. It may take more time to process the scanned image by the scanner if it is 24 bit color. The image is sent to the computer Harddisk and if the disk is full or if it had not been defragged for a long time, the sectors may not be contiguous for speedy writing, This will slow up the scanning. Ensure the disk has large space. 'Scan ahead' slows down scanning speed. (Without scan ahead, the next page is fed only after processing, whereas when selected, just after the previous page is scanned, the scanner start the next one)
