IQ18 Media Wrinkling or Damage

Wrinkling generally appears in areas of solid fill near the image edge. This problem is more
often seen on short-grain media. Some wrinkling of envelope flaps is expected. You may see
wrinkling on the second side of a 2-sided print on solid prints. Wrinkling could indicate a mal-
function in the Transfix mechanism.

Initial Actions
1. Check that supported media is being used. Damp, moisture-laden paper may wrinkle and
curl following printing
2. Print several solid-fill test prints as a sample.
3. Print using a higher-quality or heavier media type; try different ream of media.
