HP Designjet 4000 Printer Series - Worm Marks on HP Coated Media

Issue:
Light bands (S-shaped) in Paper axis direction where light area fills are printed, causing unacceptable Image Quality defect.
Solution
Print the Service Configuration Print and check if the level of Humidity is very low (below 30%). Increasing humidity may help in reducing the severity of the problem.
note:
The media is causing the problem and NOT the Printer. Do not attempt to try and replace Printer parts to solve this problem.
