I have bought a Jobo CPE2 with the lift and a 1540 drum with reels.
I want to use TMax 100 and 400 in D76 1:1. The instruction book
recommends a 5 minute pre rinse before pouring in the developer. Is it
essential to pre soak films if using a Jobo?
Does anyone here use a Jobo, if so, what is your method?

Don't know. I always used Nikkor tanks and reels.
