JOBO 3010

[tim_kimbler]

I developed five sheets of film in my 3010 drum for the first time this weekend. I used the recomended amount of chemical. The result was that three of the sheets of film had a purple spot on one of the long sides close to the edge near the center. I find it curious that all three of the sheets of film had the spot near the same general area. I put the film in the drum per JOBO instructions. Any thoughts?

Hi starman,

 

<p>

 

I had a similiar problem with my JOBO 3006 drum (expert) I couldn't

resist getting one of these for myself (used) After my first blunder

two weekends ago, I switched the way in which I loaded the film. The

best and recommended way is the short end first that is the width end

goes into the tube first not the length. Position the film so it is

flush with the top of the cylinder. Also note different numbers of

sheets get a different amount of chemical. ie 300mL for 6 sheets in my

case. Hope this works.

JOBO doesn't recommend an amound as far as I know. The 270ml on the

side of the drum is a minimum. As was mentioned by your other

respondant, you should use a given amount per sheet and not vary from

this. I always load film notch up, and flush with the top of the

drum. You must start dry, or at least without drops of water. I put

the correct amount of chemistry for that run and the number of sheets

I am doing in the developer bottle, set the chemistry amount to the

next higher level than the bottle holds total, and let the Jobo empty

the bottle. Jobo is not accurate. When I fill a bottle with 1000ml

of solution and set it to use 730ml, it almost always uses 900ml to

1000ml.

I have been using a Jobo 3010 for two years now. I do mostly C41

processing, but used to do a far amount of TMax RS development also.

You are correct there are minimum amounts of chemistry depending on

the number of sheets of film being devloped to use and published by

Jobo. I follow the charts to the letter. When I first started I had

problems similar to yours. My problem was because I placed the film

in the tubes backward. I had the emulsion side facing outward rather

than inward toward the center of the tube. When the film is installed

properly the film id tabs should be on top and to the right when you

are facing the film in the tube. Hope this helps.
