4.If the problem persists, analyze pattern number 7 in modules A through E of the diagnostic plot. A correct example is given below, followed by two incorrect examples. Note that there is a black ring near the center of pattern 7. In this step, you must look at the region near the black ring. If you can see discontinuities in the black and white lines, call HP support and report a “defocus or blurring” error.

Incorrect paper advance, skew during scanning, or horizontal wrinkles

You may encounter problems with some thick glossy originals being moved through the scanner’s paper path. In some cases, the original may become skewed during the scanning process.

If some of the paper rollers are not working correctly, you may find small horizontal wrinkles in the scanned image, due to the paper being stuck in some regions while not in others.
