Multiple 451.05 or 459.05 Paper Jams when Using Lightweight Media

Recommended solution

NOTE: This issue has been observed mostly with 024-Boise Cascade 16# LT paper. However, you may encounter this type of issue with any other lightweight media brand as it is related to how the paper curls during the printing process.

The printer has no settings that can be adjusted to avoid this error. What you can do is to reduce the effect of curling by using media that is dry and fresh out of a ream. If the media has been sitting in the tray for quite some time, flip it over in the tray before printing it.

Make sure also to remove the printed sheets from the output bin before the stack height reaches half of its maximum level.
