JOBO Processor care package... Now what?

[StoneNYC]

"4. Don't bother with the 4x5 drum insert that has separate chambers for the sheets (like a revolver's chambers), it is known not to give optimal development."

I Know this doesn't apply to you since you've got the wrong machine but the above bullshit is simply not true.
I wouldn't trust anything this person says regarding jobo processing.

Yea, I was very confused about that too as I've heard nothing but positive things about the expert drums.

It appears I am mistaken, although I have read numerous accounts of the 2509 reels (even admitted by jobo) giving increased density on the edges of film.

I apologize for any confusion, I was simply relaying what I have read on LFPF and photo.net in regards to issues with 4x5" roller processing.

No need to say that my knowledge of my own processor is completely invalid.

As for "not having the right machine" I'm not sure what you're talking about, wildbill, as far as I know the CPP2 can handle any and all drums, expert or otherwise.

Well considering everything that you just said in the statement is also wrong, I am starting to question the rest of your answers LOL

First off, I have the CPE processor not CPP2 so mine is different and doesn't take the expert drums...

Two the 2509 reels ARE NOT the expert drum "gun revolver looking" processors... The EXPERT drum is the gun revolver, the 2509 is the one that my multitank 5 uses which I have heard aren't as great for some films because of the issues you mentioned, however I'm not buying a new processor NOR the expert drums anytime soon even if I would prefer the expert drum, it's just not in my budget (hence taking this CPE at rock bottom prices...

Also, you're taking heresay and not actual experience, AND quoting photo.net... Not the best source LOL

 

[Chris Lange]

Everything is wrong? The only thing I was mistaken about was the 4x5 tank, man. IN MY EXPERIENCE doing double 120s is a bitch, and I don't bother, the only "heresay" was on the singular aforementioned point, which I already identified as an error on my part. I love my CPP2, I use it every time I'm in my darkroom.

No, the 2509 reels do have issues sometimes, they are nothing to do with Expert Dums which are really like a revolver with a set of tubes encased in a cylinder.

Stone, The processor you have is as stated a CPE, the tempering bath that accompanied it is called a TPE, they were later merged to become the CPE2.

I have a TPE but use it for my 35mm and Roll Film stand and semi stand processing as the film tank sits in the waterbath and temperature is maintained over the development time.

I also have a CPE2 which I no longer use and would have been ideal for you but for two exceptions, 1) it is 240 volt and 2) it is in the UK.

The reason I no longer use the CPE2 is that a year or so ago I was fortunate to find a late model CPP2 with lift in mint condition on ebay for 450 Euros delivered from Germany, I really lucked in with that and since buying it have no longer any need for the CPE2.

So, you need to keep a look out on ebay or Craigslist for either a TPE or a cheap CPE2.

Oh and to those that say they do not use a Jobo reel to process 2x 120 or 2x 20 exp of 35mm on a single reel, I do it all the time and it does not cause me any problems.

 

[Chris Lange]

When I piggyback 120's on my paterson reels, I use the end tape from the 2nd roll to attach it to the bare end of the first...I found it easier to load it all as one piece than 2 distinct rolls and the spacer.

Good to know, thank!

Well mine is also 240 euro plug, the previous owner was German/Austrian I believe, I have to get an adapter for US for this one. However, getting it from Europe would be costly I assume. Of course I would trade and give mine to an up and coming APUG member as a "pay it forward" should I come into a newer model.

Thanks.

I was saying you got both the processor model wrong, and the reels wrong, I was also teasing you and in fun not in anger sorry that didn't come across properly.

Nah it's cool, I think there was some misunderstanding somewhere on page 3 where it was assumed that I was referring to your machine as a CPP2, when in fact I meant my own. I have the expert drums for my machine, and they are great...I use the big guy for 20x24" prints. Though there is a dearth of info floating around out there on the numerous and varied ways of doing sheet film processing with a jobo, both orthodox and unorthodox.

Is there such a thing as stand development in printing paper? No that could be interesting talk about unorthodox...

 

[eddie]

Is there such a thing as stand development in printing paper?

No, unless the paper I pulled directly from the developer, to the trash counts. For some reason, when I turn on the lights to look at those, they're completely black...

Well you're probably not diluting the developer enough...

I wonder, with the proper dilution, if it's possible... Well, that particular experiment will have to wait.

 

[Chris Lange]

Not as drastic as with film, but there have been times where I have left a print in the developer for upwards of 10-15 minutes to eke out that last bit of highlight detail. This is very, very rare, but it does work when you need it to.

Using the 3063 drum is great for 20x24 prints because I don't need to line up as many trays in my sink. I develop and stop in the drum, and transfer into a 20x24 tray for double fixing baths, and then move to a holding bath which accumulates prints until the time comes for toning and permawash.

 

[eddie]

....there have been times where I have left a print in the developer for upwards of 10-15 minutes to eke out that last bit of highlight detail.

Without any agitation? I don't see how you'd get even development.

 

[Chris Lange]

No...intermittent agitation after first five minutes...so not stand, but long dev times do exist.

Quick, someone talk about lith printing

 

[eddie]

I've never thought of doing it that way, Chris. Generally, to eke out the detail, I'll use some warmer developer and Q-Tips. Thanks for another option.

i hear you eddie,
even blowing hot air / rubbing works for me ..
or ... burning in AFTER something has been in the developer for a whle ...
it goes under the negative/lined up than burned in and redeveloped

i've heard of super dilute paper developer for like 12mins, but strangely enough i don't have the patience to do that ..

 

[wildbill]

Well, Stone's got plenty of hot air
No jobo required.

 

[StoneNYC]

Okay, so I got a plug in order to convert the euro style plug to the normal one, but it doesn't seem to be doing anything, I can get the wire to sheet up, but the motor itself doesn't spin but I'm not sure what is going to button so not sure what I'm supposed to do... I can't find a darn manual for the original version

 

[StoneNYC]

Ugh, it seems that finding a power transformer is a much more difficult task then I had anticipated...

The processor as I mentioned is a European style power supply, it runs off of 220 V 50 Hz and 150 W, that last number of the 150 W, is the thing that's causing me trouble, most of the available transformers that I can find are only 85 W

Neither RadioShack your Home Depot carry something as high as 150W ugh, stupid power...

 

[AgX]

Get two transformers and switch them in parallel.

Or use one for the motor and set the heater directly onto the 110V and use pre-heated water for the bath.

 

[CatLABS]

why do people even bother trying to find anything in stores?
I worked at a retail camera store for years and never understood why poeple walked in to a corporate chain, paid more for stuff. to be sold by folks who dont care, and then to top it off pay sales tax, when they could have ordered something online, got for A LOT less and not paid any tax... not had to talk to annoying pushy sales reps... well i am rambling.

Ebay baby - Ebay.

Or if you want a nicer unit, with all kinds of other little cool added benefits:
http://www.ebay.com/itm/Power-Brigh...ravel_Adapters_Converters&hash=item5af7da57f3

How much was thay 85w at radio shack?
Obviously, stone has found that 220V machines require that voltage regardless of the plug.
Now to really fry this pickle, you will want to find out if the machine is strictly 50Hrz or 60Hrz. While all modern Jobo processors are dual cycles, this one might not be, but at worst this might just shorten the lift span of the electronics. Label should indicate what the Hrz range is.

 

[CatLABS]

Oh i forgot to mention, you want to have at least twice the wattage on the transformer, as when the thermostat clicks in it might spike and draw double the wattage, causing a fuse to pop, the 500W would be even better in that sense. And it would serve as an additional outlet for, well anything.

 

[AgX]

That Jobo processor is rated 50Hz.

 

[CatLABS]

That Jobo processor is rated 50Hz.

That then is truly a bummer. It might not work at all even with the correct voltage, or if it does might cause damage to the unit (electronics and motor, not heater coil) over a short, or long ish period of time. The motor will run 20% faster, not a big deal in this case.

You can google the effects of appliances rated for 50Hrz plugged into 60Hrz sockets, or one of the MANY electrically inclined users can chime in with a proper scientific explanation.
