IQ3 Unfused Image
The printed image is not fully fused to the paper. The image rubs off easily. A cold environment
affects the warm-up time, while high humidity has an adverse effect on fusing. Also, media
weight and composition affect fusing performance.
Initial Actions
• Check the printing environment. A location that’s too cold or humid reduces fusing perfor-
mance.
• Inspect the media path for debris, such as staples, paper clips, and paper scraps.
• Verify that the media type is set correctly.
