Mode of Operation
The processor develops, fixes, rinses and dries your films. The temperatures,
speed and replenishment rates required for processing various types of film-mate-
rials can be individually selected and stored in the microprocessor control unit.
Automatic filling and heating
When the machine is switched on, the water tank fills and chemical baths heat up
automatically. During this procedure the display shows two serifs “--” and the devel-
oper temperature button blinks until the set temperature has been reached. The two
serifs show the operator, that the machine is not yet ready for processing. Once the
set temperature is reached, the machine is ready for processing. The developer
button no longer blinks.
Stand-by mode
After a film has been processed, the machine automatically switches to the stand-
by mode during which the bath temperatures are maintained. The bath temperature
is maintained. The built-in circulation pumps ensure that the bath liquids are circu-
lated and the temperature is evenly maintained and constant. Every 20 minutes an
anti-crystallisation programme starts to rotate the rollers, which avoids the building
up of aggressive crystals on the rollers within the machine. During very long stand-
by periods, and after a set time, the control unit activates a replenishment cycle to
avoid oxidation of the chemicals in the machine (time replenishment).
Film registration
The special impulse-reflex-lightbarrier for film registration has been constructed in
such a manner that even infrared sensitive films are not exposed. When a film is
fed in, the lightbarrier starts the machine.
Automatic replenishment
The quality of the developer and fixer chemicals is reduced when films run through
the baths and for this reason a regular replenishment of the chemicals is necessary.
By means of the lightbarrier, the film surface of processed films is measured. After
approx. 0.25 m
2
of film has passed through, a replenishment cycle is activated.
During this cycle, chemicals are pumped up from the replenishment containers into
the machine. The replenishment quantity can be adjusted by setting the replenish-
ment rate.
