4.6 Cannot perform copy 4 Description of problem The area around an image gets smudged. Cannot switch to the 2-Sided > 1-Sided or 2-Sided > 2Sided function. Check points Is the Original Cover Pad dirty? Is the paper selected of a size larger than the original size? (When copying at full size or 100.0% zoom ratio) Is the size or orientation of the original different from that of the paper? (When copying at full size or 100.0% zoom ratio) Have you selected the zoom ratio for reduced copying that is suited for the paper size? (When the reduced copying zoom ratio has been selected manually) Have settings been selected that cannot be combined? Remedy Clean the Original Cover Pad with a soft cloth dampened with a mild detergent. Select a paper size that is the same as the original. Otherwise, tap [Zoom] on the copy main screen to select [Auto], and perform enlarged copying at a zoom ratio matching the paper. Select a paper size that is the same as the original. Otherwise, re-load paper in the same orientation as the original. Select the zoom ratio that matches the paper size. Otherwise, tap [Zoom] on the copy main screen to select [Auto], and perform reduced copying at a zoom ratio matching the paper. Check the combinations of the selected settings.
