Reason: More info
I can not see the fault
The background comes out on the double side?
The following issues are solved in this firmware.MFP firmware Ver.GCJ-D1
5. A black line image was occurred on the leading edge paper for first copy/print. [PEBAU_13000297
If doing double sided it comes out on page 2 (first page printed) page one would be okay
see attachment and zoom in. it is hard to see but its hard to explain! like a grainy image.
Struggled to pick up the background on the scan will take a photo hopefully you can see the fault then
It appears the border erase is OK so how does the background an lines look like in detail (magnification glas) - perhaps some sort of "digital" pattern? This might lead to bad memory/DIMM or laser issue.
