Developer temperature
The developer temperature of the different film-materials depends on the develop-
ing time. The faster a film has to be developed, the higher the temperature must be.
The developer temperature can be set between 28-37 °C according to the individual
requirements (Setting the developer temperature: see “Setting the working param-
eters:” on page 17). If the temperature of the developer bath is lower or higher than
the set value, then the developer temperature button (5) is flashing and the display
shows two bars “– –”. Before feeding a film into the machine, wait until the temper-
ature has been reached and the displayed bars “– –” disappear.
The following chart shows guiding value relations between developer temperatures
and processing times. Variations are possible depending on the various films and
chemicals.
Dryer temperature
The dryer temperature cannot be set in degrees Celsius. However the dryer output
can be set in a range between 10-99 % (100 %), to adapt it to the film material to
be processed.
“95” for example, corresponds to 95 % of the maximum output of the
dryer heating. To avoid dryer spots on the film, the dryer output may not be set too
high. Adjust the temperature so that the film just gets dry (Setting the dryer temper-
ature: see “Working Parameters” on page 17).
Remark: Depending on mains voltage, dryer temperatures above 65 °C may under
certain circumstances not be reached. The information in the table below are mere
guiding values. Different combinations of film material, chemicals and ambient con-
ditions may require different dryer output settings.
Replenishment time
The replenishment of the developer and fixer chemicals is automatic. By means of
the film detection switches at the film-feed, the surface of the processed films is cal-
culated and after 0.25 m
2
film a replenishment cycle is automatically activated. The
replenishing volume can be set by means of the replenishment time. The replenish-
ment time may be set in a range of 10-99 s. The replenishment can be switched off
by entering
“0” . This is advisable in rare cases only.
