Hi Guys,

Please assist with the below:

I have a B554e when doing double sided prints or copies it produces some black pages on the second side.

Please see points below of what troubleshooting I have done so far.
1.Changed Drum and dev.
2. Changed ADF and dual scan board.
3. Changed PRCB board.
4. Format SSD.
Still no luck. This normally occurs on long runs, I am going through with and H.V tomorrow.

If anyone has had this issue kindly share your thoughts.
