How to Load Film on JOBO Plastic Reels
From time-to-time, we hear of customers having difficulty loading our #1501 and
#2502 walk-in plastic reels. They are actually quite easy to use, but there are a few
tips, which can make the process easier.
1. Snip the lead corners of the film. Right angles on the corners of the film can
snag on the radiating arms of the reels. By snipping the corners to about a 45-
degree angle, the film will slide into the reel more easily.
2. On the right side of the reel, you will find a red clip, attached near the center of
the reel, and pressed in between the spirals about halfway through the reel.
Gently pry the red clip out of the middle of the spirals to allow film to pass by
it.
3. Pull the film into the mouth of the reel (the opening on the outer layer of the
reel) and then continue to pull it about half way around the reel. This will make
it easier to advance the film in the next step. The mouth of the reel will be
facing you for the rest of the procedure.
4. One of the pie-wedge shaped sections of the reel, is cut more deeply than the
rest, allowing the film to poke out slightly. We refer to this section as "the
window". Hold your hands flat on both sides of the reel, and place your index
fingers on the edge of the film appearing out the window. Now press the film
with your right index finger, and move it forward and away from you. Now
release your right index finger and press against the film with your left index
finger, and move it forward and away from you. Repeat this continuously until
all of your film is on the reel, just barely inside the mouth of the reel. (Left,
right, left, right, etc.)
If you are loading 120 or 220 film there are a couple more helpful points.
1. When you remove the film from the paper backing, tear the tape right at the
end of the film. You want to leave the tape stuck to the film to add a little more
rigidity, but you don’t want excess tape flapping around. It might get in the way
of even processing.
2. Sometimes the film waiting to be loaded onto the reel will be rolled up in a tight
coil, which can make it difficult to feed it into the mouth of the reel. If this
causes any problem for you, try using your thumbs to move the coil an inch or
two away from the mouth of the reel. This allows the film to enter the reel
mouth at a lower angle, closer to parallel to the outer spiral, causing less
interference.
3. If you want to load two rolls of 120 film on the reel, continue as described
above, but load the film all the way into the reel, until you are no longer able to
advance the two sides of the reel alternately. Press the red clip back into the
reel. Now move the film backward about 3 strokes (left, right, left). This will
allow you to continue advance the second roll into the reel.

Now load a second roll of film into the mouth of the reel, just as you did
the first, but concentrate on pressing the film just on the outer layers of
the reel. (You don’t want to advance the inner roll any further.) Continue
to advance the film into the reel, until the trailing end of the film is just
barely inside the mouth of the reel. You’re done.
JOBO’s plastic reels and our stainless steel reels made for JOBO Fototechnic by
Hewes, produce essentially identical results. We have measured the density
characteristics of the 1501 reels versus both of the stainless steel reels (the
traditional versions plus our new ones that fit on our plastic center cores) and we can
find no measurable difference, across the film nor along the length of the film. So
your decision to select either the plastic or the stainless steel reels can be made
simply on your preference for loading styles. The results will be the same with either
version.

Cogs and Magnets
Introduction
To use a tank or drum on the processor (without the JOBO Lift attached) a magnet must be
mounted on its bottom. You must have a cog installed on a tank or drum lid to allow coupling with
the accessory JOBO Lift or Autolab processor.
Some tanks and drums come with a magnet or cog already installed, some do not. At least one of
these mounting systems must be present to use a tank or drum on the processor. See the
instructions below to determine if you need to obtain a magnet or cog for the tanks or drums you
own, or intend to purchase.
The mounting procedures below will prepare your tank or drum for use on your JOBO rotary
processor.
Mounting a Magnet On a Tank or Drum
To use a tank or drum on a manual processor (without the JOBO Lift attached), a magnet must be
mounted on its bottom. A magnet is not required for any of the Autolabs.
The Magnet, part number 1504, will allow you to use 1500, 2500, and 2800 series
tanks or drums on a magnet drive processor. (The 3000 series drums are too large in
diameter to use a magnet coupling.) This magnet is permanently attached to the tank
or drum in the following sequence. You will need one magnet for each tank or drum
you wish to use.
1. Remove the lid from the tank or drum.
2. Note the location of the four pins on the magnet. Note also the four short raised tubes on
the bottom of the tank or drum.
3. Place the tank or drum upside down on a smooth, hard surface.
4. Align the four pins with the raised tubes, and press the magnet down vigorously.
5. Check that there is no gap between the magnet and the bottom of the tank or drum.
When the magnet is properly mounted, it should not come off. If the magnet
does not stay securely on the tank or drum, follow this procedure. After doing
the above steps, turn the tank or drum right side up. Place a piece of wood
(such as a 2x4") slightly longer than the depth of the tank or drum, into the

(such as a 2x4") slightly longer than the depth of the tank or drum, into the
bottom of the tank. Center the piece of wood in the tank. Rap the top end of
the wood with a hammer. Inspect the mounted magnet for gaps. Repeat if
necessary.
WARNING: Do not try and mount the magnet on the tank by pounding on the
magnet. This will likely damage the magnet or split the tank.
To use a magnet-equipped tank or drum on a JOBO Lift equipped processor or Autolab, simply
add a Cog (#1505) to the lid. Do not remove the magnet when using the tank or drum on the
JOBO Lift or Autolab.
If you are purchasing a tank or drum, note its four-digit part number. If the part number ends in '1'
(such as 2521 or 2551, etc.), it already has a magnet attached. All other tanks and drums do not
come equipped with a magnet. Tanks that have the last number of '3', have cog type lids. These
lids would have to be replaced to use them with a magnet drive processor. Replacement lids
(without cap, funnel, or beaker) are available as parts from JOBO. The 1500 series requires
#91034, and both the 2500 and the 2800 series require a #91036 lid. (There is no non-cog lid
available for the 3000 series drums.) The #03046 membrane cap is needed by all three series lids.
Back to Top
Mounting a Cog On a Lid
You must have a cog installed on a tank or drum lid to allow coupling with the JOBO Lift or
Autolab. Some tanks come with the cog already installed. If you are purchasing a tank, check the
JOBO part number of the tank. If the first or last digit of the four digit code is a '3' (3010, 2523,
etc.), then there is already a cog installed in the lid. If the first or last digit is not a '3', then you will
need to purchase a Cog (#1505) for the tank or drum.
One cog for each tank or drum is required, as they are permanently mounted into
the lid, and cannot be removed. If you wish to keep the lid for hand or magnet
processing, get a replacement cog lid. The JOBO part number for the
replacement cog lid in the 1500 series is #1503. Both the 2500 series and the
2800 series use the same replacement lid, #2503. This replacement lid comes
with a funnel and a stopper. (The stopper is placed in the funnel only when
replacing the beaker. The stoppered funnel is used exclusively for print
processing with a lift.) The 3000 series of drums cannot be used with the magnet drive. 3000
series lids are always supplied with a cog.
You may use the lift with a tank or drum having a magnet attached on the bottom. The daylight
loading tank #2400, or the discontinued series 1000, 2000, and 4000 tanks or drums cannot be
equipped with a cog.
The procedure for mounting a cog is the same for all tank or drum lids.
1. Remove the lid from the tank or drum. Remove the red membrane cap and funnel or
beaker.
2. Place the lid, red ring down, on a hard and smooth surface.
3. Place the cog, wide side down, into the opening for the cap, at a slight angle.
4. Press the cog down with your hands. (You may find it helpful to lean towards the lid to apply
a firm pressure.)
5. Examine the seam between the cog and the lid for gaps. When seated correctly, there will
be no gap between the cog and lid. (If you can place a fingernail between them, the cog is
not seated fully.)

If you cannot seat the cog fully, by hand, use this procedure. Seat the cog as far
as you can by hand. Place a flat piece of wood, on top of the cog. Rap the board
smartly (centered over the cog) with a hammer. Repeat as necessary until the cog
is fully seated.
If the cog comes off the lid during processing, it was not completely seated. Re-
seat the cog.
The cog has a small (1 1/2" or 35 mm) red ring that functions as a washer and
seal between the lid and lift. It is located just inside the gear ring. This ring will
wear with long, heavy use, and may need replacement. If you find the washer is staying on the lift
when you remove the tank or drum, replace it. The cog lid washer's part number is #07095. The
tank lids that come with the ATL-1000 processor do not have a washer installed in the lid. If you
wish to use one of these lids, be sure to place a washer in the lid. If you use a lid without a washer,
the junction of the JOBO Lift and tank will leak.
Never try to remove an installed cog from its lid, as you will break either the cog or the lid.

1500 Tank System
Product Summary:
The motto of the 1500 series line of tanks is "price them so hobbyists can afford them, but make them
provide lab-quality processing". (In case you're wondering, it wasn't easy.) 1500 series tanks are used
for inversion (hand) processing and rotary processing on anything from a small CPE-2 Plus
processor, all the way up to a full-blown ATL-2500.
Key Features
Crack resistant
They're made of flexible plastic -- it makes them crack resistant (we can't say crack "proof" because if you
threw one against the wall hard enough on a cold Winter morning it might crack).
You CAN take it with you
Many, many people have come to appreciate the modularity of JOBO tanks and drums. Unlike other
manufacturers, if you want to add more developing capacity, you have to buy a whole new tank (the most
expensive part). With JOBO tanks, if you have a two-roll tank #1520 and you want to increase the capacity all
you need to buy is an extension module #1530.
Also, if you ever want to move up to a rotary processor like the CPE-2 Plus, you'll be able to use the same
tanks you used for hand processing.
Save money!
You save money in three ways: The 1500 series tanks use very little chemicals to process film, the 1500
series allow you to process two rolls 120 film per reel (not loaded back-to-back), and the third way you save
money is if you move up to a rotary processor, you use a little over half the chemicals you use by hand
processing.

2800 Series Print Drums
Product Summary:
The 2800 series print drums are designed to allow you to be able to process prints in the daylight,
regardless of whether or not you're using a JOBO processor (by using them with the Roller Base).
Also, like JOBO film tanks, they are a modular system which save you money.
There are two other print drums not shown here (#3062 and #3063). They are not the same modular
design.
Key Features
Modular
When you need to move to a larger format print, simply add an extension piece. The same tank you use for
test strips can be used for larger prints.
Daylight operation
Whether or not you decide to purchase a JOBO processor, you still get the benefits of the tanks being light-
tight.

JOBO Drum Expert
Product Summary:
The 3000 series Expert Drums are designed to process sheet film with the highest quality possible.
(Please read that sentence again, it's the most important sentence on this page). It doesn't matter
what system of development you're contemplating; hand processing, rotary processing, hanger
processing, or any other method -- using the Expert Drums will yield beautifully even edge-to-edge
development.
Key Features
Utterly random
It normally isn't a good idea for a company who sells photographic equipment to declare that their stuff
provides random processing. After all, we all want consistency while developing our film. The reason we
state that processing with the Expert Drums is "utterly random" is because the unique design of the drums
dares the chemistry to try to develop a pattern. It can't! What this means is you won't get streaks or spots,
and the density will be completely uniform.
How can I start using the Expert Drums!?
The Expert Drums fit on the JOBO CPA-2, CPP-2, and ATL-2x00 (they don't fit on the CPE-2 or ATL-
1000/1500). (One interesting point about the Expert Drums: We hear time and time again that people
purchase a processor to get to use the Expert Drums. We understand that's like saying people buy a luxury
car because the like the tires that fit it. But it's true!)

The Drums
[Drying Rod, Cog Lid with Light Trap, Drum Body, Film]
Back to Top
Opening the Drum
[Foot Pump #3360]
The lid is most easily removed with foot pump #3360. Firmly grasp the lid while pumping up the pressure inside the
Drum. Do not place any portion of your body over the lid.
If you are removing the lid by hand, grip the lid around its edges not through the center fill opening.
Danger: Never blow in the lid to remove!

Loading the Drum

[Inserting Film Into the Expert Drum #3010]
Films must be inserted straight and not turned at an angle.
While loading the Drum, leave about 1/2 inch (12 mm) of film protruding up out of the cylinder as a "flag" to identify the
cylinders which already have film loaded in them. Before closing the lid, push the film down to its final position.
When loading 4 x 5 inch film, push the material into the cylinder only until it is flush with the top of the cylinder. When
loading the Drum with films of sizes 8 1/2 x12", 8x10" or 5x7", push the material to the bottom of the Drum cylinder.
Caution: The inside of the Drum and lid must be dry!

Closing the Drum
Put on the cog lid and press firmly all around its edges to assure an even fit. This is necessary for proper rotation.

Processing With the Drums
1. Set the lift arm coupling to "System 3000". (Upper connection)
2. Adjust water level in upper trough to approximately 1/4" (6 mm) above the bottom edge of the Drum.
3. Preheat or pre-rinse the Drum in the trough for five (5) minutes.
4. Set rotation speed for 50 rpm on ATL-2 or 3. (Approximately speed 4 on ATL-1, CPP-2 or CPA-2.)
Caution: Do not use the intermittent lift (rocking motion or lateral agitation) on any of the older ATL
processors, which offer this function.
Caution: The Expert Series of Drums will fit on JOBO CPA-2 and CPP-2 manual processors. Care must
be taken! A loaded Expert Drum can be very heavy and strain both the rotation motor and lift of manual
processors. Use both hands to help the lift when raising it, and observe the motor speed. You may need
to increase the rotation speed control setting to obtain desired speed. (Measure speed with reversing
switch set for one direction of rotation for testing only. Reset to reversing directions before processing.)

Filling Quantity
The actual amount of chemicals needed will depend on three factors; the amount of film surface being processed, the
chemicals being used and the minimum solution level required by the Drum for proper solution coverage. The tables
below provide a concise way to select the minimum chemical requirements for most processes. But some processes
(particularly dilute black and white developers) may require higher solution levels in order to have sufficient active
chemicals for the surface area to be processed. Use these tables as a starting point. If the initial test results indicate
chemical exhaustion, increase the solution levels.
Note: For intermediate filling quantities on ATL processors, select the next higher quantity on the ml dial.

Film Processing
For each film size we recommend the following quantities of chemistry as a basic guideline for practical use.
Back to Top
Basic Film Table
Film Size E-6 / C-41 B & W
4 x 5" 33 ml 50 ml
5 x 7" 57 ml 85 ml
8 x 10" 126 ml 200 ml
81/2 x 12" 162 ml 240 ml
Caution: Never use a quantity of chemicals less than the Expert Drum minimum quantity. It must have at
least the minimum quantity to properly cover the films or prints in the drum.

Paper Processing
The #3004, #3005 and #3006 Expert Drums are easily used for paper processing. Papers should be loaded, the same
as film with the emulsion to the inside of the tube and away from the tube wall.
Minimum Chemical quantities as listed on the table should be maintained. Apply the following quantities of solution per
8x10" print, and use either the minimum chemical quantity listed for the specific Drum you are using, or the quantity
computed from this list, whichever is higher.
For each print size we recommend the following quantities of chemistry as a basic guideline for practical use.
