The image has a wood-grain appearance
(aeroworms)
Aeroworms are wavy, horizontal bands produced by air-induced dot placement error
(DPE). In extreme cases, aeroworms give the image a wood-grain appearance. The
problem occurs most commonly on 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
