2.3 Product information
The exposed film passes through different
zones within the Dürr XR 24 PRO X-ray
developing machine: the developing, fixing,
rinsing and drying zones.
When the machine has been switched on, the
developing bath and the fixing bath are
heated to the set bath temperature (e.g.
28°C) at a rate of 0.5°C/min. The machine is
then ready to be operated. It starts operating
automatically when a film is slid inside. The
film is transported through the machine. As
soon as the message “MACHINE LOADED”
stops flashing on the display, another film can
be introduced, or up to 6 intra-oral films, can
be introduced together. When the film has
passed through the whole of the machine, it
switches automatically to stand-by.

heating-up phase for the developing bath and
the fixing bath begins. The time remaining
until the correct temperature is reached is
displayed in the following manner: “WAITING
TIME… MIN” (display flashes). The machine
does not start at this point.
The bath begins to rotate when it is being
heated up.
place, the chemicals are pumped from the
developing tank and the fixing tank (volume of
5 litres for each tank) into the lifting tray (22)
via the circulation pump (14).
When the set temperature is reached, the
display lights up. The “MACHINE EMPTY”
message appears, indicating that the
machine is now ready to be operated.
As soon as the set temperature falls below
more than 0.5°C, the continuous heater and
the circulation pump (14) are switched on
again.
When a film is slid into the machine, the
start flap (2) opens and the “MACHINE
EMPTY” message flashes on the display
At the same time, a signal for lowering the
lifting tray (22) is triggered and the water
valve (15) opens. The drier heating unit (10),
drive motor (12) and circulating pump (14)
(for rotating the developing bath and the
fixing bath) start up.
The time it takes the film to pass through
the machine is controlled by a tachometer
generator (12a). The lifting tank’s rising and
falling movements are controlled by the disc’s
and the light barrier’s (19a) rotational speed.
,,
, the display is illuminated. The
,,
While this process is taking
is pressed
Should the outflow pipe be blocked, a signal
is sounded via a level sensor (13). The
water valve (15) closes and no more water is
fed into the machine.
When the film has been slid into the
machine, the start flap (2) closes. As soon as
the message “MACHINE LOADED” flashing
on the display goes out, another film can be
introduced, or up to 6 intra-oral films, can be
introduced together.
If no other film is slid into the machine when a
particular film has passed through it (this is
signalled by a sound) the lifting tray (22)
moves upwards (to stand-by position),
indicating that the machine is now empty.
The drive motor (12), water valve (15) and
drier heater (10) are switched off. When the
machine is in stand-by position, the
developer’s and fixer’s roller packets are
completely immersed in the chemicals. This
prevents deposits from forming on the rollers.

2
26
27
chemicals may overheat or that the
films might be pre-exposed.
• The room in which the machine is being set
up must contain a R3/4” bibcock (27) with a
ventilation pipe, an outflow pipe (28) with a
ventilated plastic trap, and an earthed plug
(26). Ideally, a washbasin should also be
situated close to the machine.
The operating staff must have easy
access to the bibcock (27) and the
earthed plug (26)..
• We recommend that the XR 24 PRO be set
up in a darkroom. If the machine is
up in a darkroom, a daylight attachment
(24) (DL24 or DL26) must be fixed to it.
• The following should be taken into
consideration if the machine is being used
with a daylight attachmentwith a daylight attachment

12. FIRST TIME OPERATION
The XR 24 PRO developing machine has
three settings which determine the amount of
time it takes a film to pass through the
machine. The following values are set for the
machine “ex works”:
Intra-oral films 6 min. (INTRA program)
Extra-oral films 4 min. (EXTRA program)
Endodontal films 2.45 min. (ENDO prog.)
Note: It is not possible to archive X-ray films
which pass through the machine during this
short period of time).
- Developing bath and fixing bath
temperature: 28 ºC
- Drier capacity: 30%
When films with different drier capacities,
and which pass through the machine in
longer or shorter periods of time, are used,
the values can be changed in accordance
with the films which are to be processed.
In this context, see the list of films, point 14.7.
For a program overview, see the chapter on
USAGE
The machine may only be

skin. Serious injuries can be
incurred.
• If no developing and fixing roller
packets are used, the chemicals
cannot be directed into the tanks.
There is a danger of the chemicals
being mixed together.
• The developing unit should never
be operated without fluids
(chemicals, water). This can lead
to a malfunction in the heating
control system.
In order to guarantee that the films be
of a consistently high quality, the
machine must be switched on every day.
Care must also be taken to ensure that the
temperature in the area surrounding the
machine is not higher than the temperature of
the developing bath!

Every 4 weeks
Change chemicals without using
replenishing unit (91) (see paragr.15.1 below)
Chemicals should be changed every
4 weeks if a maximum amount of 10
intra-oral and 3 extra-oral films are
used on a daily basis.
The instructions on how to clean the apparatus
should be kept close to the machine and
should be displayed in poster (A3) format.
Every 3 months
Change chemicals using replenishing unit
(91) (see paragraph 15.1 below).
1 x a year
Clean the roller packets using the
XR Cleaning Set
60
61
The tanks do not have to be cleaned
with chemicals. Only the roller
packets need to be cleaned using
chemicals using the XR Cleaning Set
(cleaning tray, accessories and
instructions for use).
Order no: 1700-007-00.

15.1 Changing the chemicals
15.1.1 Drain off the chemicals
• Switch off the machine using the mains
button.
• Pull the earthed socket out of the mains
91
plug (61).
• Remove the lid (60).
• Check if the collecting tray (39) is empty; if
necessary, empty into main tray (63).
39
63
It is important that the collecting tanks
be empty; if they are not, there is a
danger that they will overflow if the
chemicals are drained out of the tanks.
• Remove floating lid from developing bath
and fixing bath. Drain and put to one side
• Unscrew small plugs from lifting tanks, then
unscrew large plugs from tanks
• Empty collecting tray
• Unscrew lid from collecting tray. Hang pipe
ends in neutral tray
This prevents water from getting into
the collecting tray and the main tray
when cleaning is being carried out.

The developing machine must never
be used without roller packets. If
no roller packets are used, the
developing and fixing fluids can
spurt up and out of the developing
unit because the water is not being
redirected into the tanks! Chemicals
irritate the eyes.
• Close green stop flaps and seals
• Swivel display back into place
• Replace lid (60)
• Plug in mains plug (61). Switch on machine
by pressing mains plug.
• Start up machine. Insert 3 x 4 films into layin point (1) until start flap is actuated.
Leave films lying in this position for about 4
min.
• Allow machine to run for ca. 10 min. (pipes
and circulatory pump are thus automatically
cleaned).
• 10 min. later, switch off machine by
pressing mains button and pull out mains
plug (61).
• Remove lid (60)
• Swivel display upwards
• Open green stop flaps (44) and seals (45).
28
34
35
• Remove roller packets for water (6) and
developer/fixer (5); tilt sideways to allow
water to drain off.
• Unscrew large plugs for developer (21) and
fixer (18); allow water to drain off from these.
15.1.3 Pouring in chemicals
The information on pouring in the
chemicals refers to the
54
52
“DÜRR AUTOMAT XR” chemistry.
• Screw the large plugs for the developer
(21) and the fixer (18) into the tanks (see
pg. 28)
• Reconnect developer and fixer pumps to
collecting trays
• Place partition (52) between developing
and fixing tank.
The partition prevents chemicals from
mixing together when they are being
poured in.
Chemicals can cause damage to
health. They irritate eyes and skin.
Danger of serious injury to eyes
exists. Irreversible injuries may be
caused.
Wear protective gloves and glasses
when pouring in chemicals.
If chemicals get into eyes, wash
thoroughly with water and consult
doctor.
Clean hands under running water
when work has been carried out.
36
For further information on safety
measures, see following internet site:
http://www.duerr.de.
Dürr Dental has converted from the
two-part to the one-part
“DÜRR AUTOMAT XR” chemistry
(pict. 35 and 36). The advantages are:
- These are easier to handle and
- result in a more constant
development quality
1. Filling the fixing tanks (F) (Picture 35)
Carefully pour into large red bottle (avoid
splashes so that chemical do not mix
together) and fill with water (max. 20 ºC) to
upper marking (54).
2. Filling the developing tanks (E) (Pict. 36)
Carefully pour into large black bottle (avoid
splashes) and fill with water (max. 20 ºC) to
