C1 print defect

[Alessandro72]

I attach a scan of a print made with my imagePRESS C1.
As you can see there are 3 lines.
What could be the problem?
Thanks for your precious help.

Make sure the dust proof glass is clean.
Check the the drum for score lines.
Also stop the copy before it hits the fuser. If its clean, its probably fuser related.

is that a paper feed image ??
are all colors exhibiting the problem ??
did you inspect the developer mag rollers ??
post a PG10 & some PG5's of separate colors-


a white line running from lead edge to trail edge on all four colors on prints and copies>
Check the shutter to the salt sensor and the patch reading sensor.

Make an MP5 for each color and a 10 pg. Note the occurrence of the defect.
Check and replace the primary corona grid of the primary corona wire, check the ITB, check the status of the external transfer roller. Sometimes it may happen that the grid and be dirty primary corona wire or corona and cause failures of any kind. But for better verification of the defect you should post impressions in five PG and PG10 for each color.
