Stand-by mode
When no film is being processed, the machine switches to Stand-by. The chemicals
remain at a constant temperature. The film transport and water inflow activate at in-
tervals to avoid crystallization of the chemicals on the transport rollers. Entry of the
next film is possible at any time.
Switching the machine on
The processor is switched on at the main power switch on the front side. After
switching on, the water tank will be filled up and a replenishment cycle will be car-
ried out. The developer will be heated up. Until the tempearture is reached the LED-
display “Bath temperature” will be flashing. When the processor is ready and the
bath temperature reached, a long signal tone can be heard.
Bath temperature
The processor heats up the chemicals automatically to the dial-set temperature.
When this temperature is reached for the first time after switching on the machine,
a long signal tone can be heard. This is also the case when the temperature is
changed by the dial switch.
If the difference between actual and dial-set temperature is more than 1 °C, the
bath temperature LED will flash. If a film has been fed in and the temperature is not
reached, a warning sound will be heard.
Display “Film feed”
If films are fed into the processor without clearance one after an other, then this may
cause a film jam. The light “Film feed” is on during feeding of a film. After the film
has been fed in completely the light goes off. Additionally an audible tone indicates
that the next film can be fed in.
Manual pumping
The function “Manual pumping” activates the replenishment pump and it pumps
chemicals into the tanks in addition to automatic replenishment. Turn the dial to the
position “Manual pumping” and chemicals will be pumped into the tanks. This func-
tion is only available during stand-by (no film in process). If the dial is left in this po-
sition, the pumping function is stopped automatically after 20 minutes. To restart a
cycle turn dial to a temperature and return to “Manual pumping”.
Please note: Films cannot be processed when dial is set to “Manual pumping”. Also
bath temperature is set automatical to 28 °C during “Manual pumping”. After ending
the manual pumping the temperature must be set again by turning the dial. It takes
some time until the temperature is reached (look at the bath temperature display).
Anti-crystallisation function
During the stand-by mode, the film transport, the dryer ventilation, the dryer heater
and the water inflow are activated every 20 minutes for a period of 20 seconds. This
prevents the build-up of crystals on the rollers.
Both chemical pumps - fixer and developer - are driven parallel
by only one motor and therefore they operate in unison.
