    New JOBO CPP2 w/Lift

    I am getting a new CPP2. Does anyone have any tips/warnings about setting it up or using it? I will be doing 2 1/4 and 4x5 film and printing - all b&W with it. I have not been in the darkroom for any extended period of time since college (25 plus years ago!). I am excited and scared all at the same time. Thanks in advance.

    when using the lift help it along with the other hand under the tank for support and help. Good luck.

    Get the expert drums for 4x5 film. More than one if you can afford it. Very expensive but convenient.

    Use the little plastic wedges and level to make sure that it is level front to back and side to side after your fill it with water.

    Drain it after using it so that muck does not accumulate in the inaccessible bottom area.

    When lowering the drum, time it so that the cog is shifting directions to avoid the loud clicking noise.

    Be careful if you have the unit on and then try to load negatives in the drums because the light from the unit might fog the film. I always cover mine so that no light gets out.

    It uses a lot of sink space. Consider a cart with casters.

    Congrats! The CPP2 is a great tool! You say it is new. Is it new, of recent manufacture, that is with the latest motor and control board? If so, get expert drums as you can afford. If not, check the serial number as the older motors really can't handle the load of a loaded expert drum. The 4x5 tank and reels work very well, also. I used them for quite a while with the CPE2 before getting my CPP2.

    Just some clarifications. Level before you fill with water. IMO, there is no need to worry about the control panel lights, unless you are loading near, they are designed not to fog paper. I have never had an issue with B&W film, but I am loading the drum on the dry side.

    Where are you located?

    I've heard about the "necessity for this "side to side" levelling before - and I'll ask again: Why?

    The last time I looked ALL the JOBO tanks were cylindrical - so why - and HOW do you level a cylindrical tank "side to side"?

    You ARE levelling the TANK longitudinally and not the apron of the machine - aren't you?

    Your processor should come supplied with two plastic wedges and a small spirit level which you can place on top of the lift, making sure the bubble is in the centre. Making sure the processor is level helps to prevent any risk of insufficient film/papar coverage if using the `minimum recommended` volume of processing chemical solutions.

    How can you tell from the serial number what vintage it is? I am looking at a used one and want to make sure it will handle a loaded 3005 drum.

    Thanks

    My processor *DID* come with the two plastic wedges... I had to buy the spirit level separately... some ten - fiteen years ago.

    "Place the spirit level on top of the lift"??

    The INSTRUCTIONS - remember them - specifically call for levelling the tank, not the apron of the machine, or the lift. What is important for coverage is the level of the solutions in the tank, and nowhere else.

    I'm still trying to figure out - and wondering - how this side to side business ever got started.

    From the "old" jobo site:
    There are times when you might want to consider having the Rotation Motor Circuit upgraded in your CPP-2 or CPA-2 Motor Unit. The strength of the circuit depends upon the manufacturing date of your processor. Newer systems like the 3000 series EXPERT Drums, have necessitated the need for increased strength in the Rotation Motor Circuit. You may want to consider upgrading the Rotation Motor Circuit if you experience the rotation speed of the tank or drum being sluggish or seem to struggle with heavier loads. The 3000 series EXPERT Drums create the heaviest possible load for the rotation motor circuit.

    The following information will help you know where your unit fits within the range of all of the rotation motor modification upgrades.

    From the list below, find which version of motor circuit you have:

    Beginning production of the CPP and CPA began with a single bearing rotation motor.

    CPP Serial # ARXXXX - 10593

    CPA Serial # ARXXXX - 10312

    1st Upgrade: Changed single bearing rotation motor to a double bearing rotation motor.

    CPP Serial # 10594 - 20455

    CPA Serial # 10313 - 13309

    2nd Upgrade: Strengthened the rotation motor circuit to accommodate larger loads, i.e. 3000 Drums.

    CPP Serial # 20456 - 21999

    CPA Serial # 13310 - 21999

    3rd Upgrade: Changed to a stronger rotation motor (same as used in the ATL's) and strengthened the rotation motor circuit to accommodate the stronger motor.

    CPP Serial # 22000 - present

    CPA Serial # 22000 - present
