Cause Action Printing on inappropriate type of paper. z Check to see if the paper you are printing on is not too thick or curled. See "Media Types You Cannot Use" on page 7. z When performing Borderless Printing, print quality may be reduced at the top and bottom edges of the paper. Make sure that the paper you are using is suitable for Borderless Printing. For details, refer to the Printer Driver Guide on-screen manual. Paper is curled. If you are using paper with either any of the corners or the whole printing surface curled, the paper may become dirty, not feed properly, or both. Use such paper after correcting paper curl as follows. (1)With the printing side (A) facing up, cover the paper with a fresh sheet of plain paper to avoid staining or scratching the surface. (2)Roll up the paper in a direction opposite to paper curl as seen below. (1) (2) (A) (3)Check to see that the paper curl is corrected to within approximately 0.08 to 0.2 inches / 2 to 5 mm (B) in height. (A) (B) Inappropriate Paper Thickness Lever setting. Media Type setting in the Operation Panel does not match the actual type of paper. Printing graphics with Intensity setting set too high. Printing beyond the recommended printing area. We recommend printing curl-corrected paper one sheet at a time. Adjust the position of the Paper Thickness Lever according to the type of paper you are printing on. See "Loading Printing Paper" on page 6. Depending on the printing content, the printing surface may become scratched even for the types of paper to set the lever to the left. In this case, set the Paper Thickness Lever to the right. * Reset the Paper Thickness Lever to the left when you finish printing. If the lever is not set back to the left, the inside of the machine is more likely to get dirty due to the wider clearance between the print head and the loaded paper. It may also reduce print quality. Check that the Media Type set in the Operation Panel (when performing wireless printing, the Media Type setting in Wireless print settings) matches the type of the loaded printing paper. See "Changing the Print Settings" on page 17. Especially if you are using plain paper to print images with high intensity, the paper may absorb too much ink and become wavy, causing paper abrasion. In this case, reduce the Intensity setting in the Operation Panel and try printing again. If you are printing beyond the recommended printing area of your printing paper, the lower edge of the paper may become stained with ink. Resize your original document in your application software. For details on recommended printing area, refer to "Printing Area" in the User's Guide on-screen manual. Troubleshooting 65
