3.5 Transport stops before film comes out, changing the cycle time
The cycle time is the processing time which starts after a film has passed the film
switch. Activate the switch in the infeed tray with a film and remove the film. Meas-
ure the time until the processor stops automatically.
Change cycle time if necessary. This can be accomplished by changing the position
of the jumper on the upper side of the circuit board, which is located underneath the
processor.
3.6 Processing time and developer temperature relation
The following chart demonstrates guide value relations between developer temper-
atures and processing times. Variations are possible depending on the various films
and chemicals. Changing the transport speed see 3.7.
Processing time
105 sec.
139 sec.
3.7 Changing the transport speed
The processing speed can be changed by changing the gear wheels. To do this the
tanks need to be emptied and the machine turned over. After removing the drive
motor the chain gears can be changed. Please note that the jumper on the circuit
board needs to be placed to the indicated position.
