Verify that the media meets paper weight and tray specifications for the media.
To diagnose the cause of wrinkled or folded paper, use the Print/Stop test in the Diagnostics
menu. Adjust the stop time so the paper stops before it enters the fuser. Open the ETB. If
paper is wrinkled at this stage, use
Table 7-16. Causes for wrinkled or folded paper (part
two, paper path exit) to diagnose the problem. If paper is not wrinkled at this stage, use
Table 7-15. Causes for wrinkled or folded paper (part one, paper path entrance) to diagnose
the problem. See
Print/Stop test for more information on the Print/Stop test.
