[Misc] duplex issue

[ducati]

I have a unique problem on an iR8705, whilst doing duplex copying the machine fails to print on one side of sequence. So, Pages 1 & 2 are okay 3 & 4 are okay buy 5 & 6 come out on single sides. (Simplex) 7 & 8 are okay. We have re-installed the current version of Firmware, performed MMI clear as well as DC Cont clear. We have also replaced the duplex driver PCB. Still the problem persists.

Has anyone come across this before? What suggestions would make to rectify this issue?

Re: duplex issue

Hmmm...If you haven't already, try scanning the copy job and see what you get. Also try copying on the glass and print double-sided to see if that changes anything -this should eliminate the doc feeder as being the issue.

Look at the copy log and check how many pages there are -just seeing if the copier is even registering the page count properly.
