(aeroworms)
Aeroworms are wavy, horizontal bands produced by air-induced dot placement error (DPE). In extreme

print jobs that are set for low-quality and high-speed. It does not occur when the custom print-quality
setting is set to “best.”
To eliminate aeroworms, select a higher IQ print setting. See Select print quality on page 82 .
