QTR-Quadtone RIP

Hi Roy,
Thank you very much for the detailed reply. 
You are right, it's not just the Landscapes, the problem affects the Potraits as well.
I now have down loaded the latest version 2.4.3
The problem happens only when I feed Manual Roll (Rear) from the back, a sheet at a time.
Has anyone ever encountered this before?
I have since started to use standard sheet feed, and I don't have the problem anymore.
Yes, the 310gm paper seems a bit thick to do it this way.
I have not try the Manual Roll slot, is that the same as Manual Roll (Rear)?

Another question:
Is the CIS system for the R1800 easy and good to use?
I used to have a CIS system set up for my Epson 1290, a little trickly to set up, but once 
it's up, it works well. Is that what I should expect?

Thank you & looking forward to hearing from you.
Best regards
Lionel
