3.6 Relation between processing time and developer temperature
The following chart demonstrates guiding values for the relation between developer
temperature and processing time. Variations are possible depending on the various
films and chemicals. Changing the transport speed see 3.7.
3.7 Changing the transport speed
The transport speed can be changed by replacing the chain wheels (*and the
chain). The upper EPAC must be removed. First loosen the screw on the chain ten-
sioner. After removing the drive motor and the drive shaft, the chain wheels can be
replaced. Note that the follow-up time must be adjusted at the controller.
The following gear combinations are available:
t = Processing time in seconds
Gm = Chain gear on motor shaft
Gs = Chain gear on drive shaft
4 Chemicals Baths
4.1 No circulation in bath
• Circulation pump works but no circulation in bath: Air lock in heating and
circulation system. Vent the pump (see page 15 item 1c).
• Particles in the pump chamber. The pump chamber can be opened easily
by removing the four clips. When closing the pump, ensure that the rubber
seal is positioned correctly and not damaged.
• Check connection of pump, circulation pump possibly defective.

4.2 Developer temperature too high
• Check fastening of the temperature sensor of the temperature controller. It
must be seated firmly on the tube, must have been installed with heat
transfer grease, be covered by a silicone hose and be insulated with plas-
tic foam.
• Temperature is set too high at the temperature controller: Set a lower tem-
perature value by turning counterclockwise. (See “Calibration of developer
temperature” on page 34.)
• If no error can be detected in the temperature sensor, the temperature
controller is defective.
