Using the Jobo 3006 (4x5 and 5x7 compatible drum) for the first time, and had a couple questions during a dry run loading dummy sheets.

1) Does the 4" or 5" edge of the sheet film get inserted first into the tubes? 2) Inside each tube there are 2 "trenches" running down the length. Is the film supposed to be situated relative to these grooves in any particular manner? 3)Finally, How does one manage to put the lid on EVENLY? The fit is quite tight, and therefore my attempts have not worked, and drum will rotate with a warble o n processor. Does it call for a thin layer of Vaseline, then cranking down on l id til it's on as far as it will go all the way 'round?

I do appreciate any assistance you can give. Andre
