IQ-19 Smear on Heavyweight
When the lead edge of paper reaches the Secondary Transfer, it increases the
Secondary Transfer section load and can cause the IBT Drive Roll speed to change
(decrease in speed). This change in speed changes the difference in relative speed
between the Photoreceptor and the IBT Belt surface in the K-color Primary Transfer
section, hence creating a smear (distorted image).
Cause
• This occurs in the black & white mode for Heavyweight Paper.
Initial Actions
• Check the paper transfer path.
• Ensure there are no debris on the transfer path.
• Change to Full Color mode (Optimize for Speed vs. Optimize for Economy)
