Ensure IQ1 Image Quality Entry RAP is performed before starting this RAP.
GP 10.
Cause
Compression of an image due to change in paper feed speed. The smear is visible 74mm (3
inches) from the trail edge. It occurs immediately after the paper trail edge passes through reg-
istration.
Corrective Action
1. Check that the paper type settings are correctly set for heavyweight paper.
2. If the paper type settings are correct and the smear still occurs, adjust the value of NVM 1
according to Table 1. Be aware that:
• Lowering the value of NVM 1 will increase smear reduction. Keep the adjustment of
NVM 1 to a minimum.
