Hi Mat.
I'm not sure if you have a Revolution with Wybron or before that or which version of the manual you have... but the current manuals for the two versions are as follows: before Wybron - rev E and with Wybron - Rev B.
I know the Wybron rev B manual added clarification about loading the gel scroll (compared to rev A) and I think that information was also added to the latest version of the "before Wybron" manual... unfortuneately, I just saw that rev E hasn't yet been posted and rev D is still on the website.
Rev E should be on the website in the next couple days. I invite you to take a look at let us know if that covers the clarification you seek. If not, let us know that too.
My apologies for the confusion the documentation caused you. Please take a look and let us know if we still need to make it better.
Thanks.
-Steve
