Troubleshooting
Calibration process
1.
Switch the processor off. While pressing the developer temperature button, switch the processor on. The display will
show the developer bath temperature as measured by the sensor.
2.
Measure the actual temperature inside the developer bath using a calibrated thermometer.
3.
At first, adjust the displayed value in 1 degree increments using the arrow buttons. To adjust the decimal, hold
developer temperature button down and press the up or down arrow button.
4.
Switch the machine off again.

Film defects
5.1 Films will not dry
•
Hot air comes out of the air channel, but the film is still not dried to satisfaction. Check the chemicals and film type. If
this leads to no solution, then the transport speed of the machine can be reduced (see the Operator Manual).
5.2 The film does not transport correctly
•
Check the positioning of the roller racks and ensure that the levers are closed. Check the gears on the roller racks.
Check the positioning of the guide bars and the roller pressure.
•
Check the gears on the motor and worm gear of the drive shaft.
5.3 Scratches, pressure marks, dirt on the film
•
Straight scratches in the infeed direction suggest a fault on the guide bars. Check the roller racks individually and
adjust the guide bars. If the guide bars are damaged, replace them.
•
Pressure marks are caused by contaminated or damaged rollers. If necessary, replace the rollers.

Replenishment
6.1 The replenishment pump does not work or works insufficiently
•
Clean the valves inside the connection tube of the pump.
Install the valve-insert correctly. Pay attention to the flow-
through direction!
•
The replenishment pump sucks air in. Check the hoses and connections.
•
Check the eccentric position. The capacity is approximately 710 ml/min
(850 ml/min with 60 Hz power mains) at setting to 100%. The minimum
setting must not be below 50%.
•
Activate replenishment (in manual mode) and while on, check the voltage of
connection X6 (DEV) and X7 (FIX) on the power PCB. If no voltage can be
registered, replace the power PCB.
7
Dryer
7.1 The display shows error message "E4"
The following parts should be checked and if faulty be replaced:
•
Power PCB (in standby, no voltage at X12)
•
Temperature sensor
(see "The dryer temperature display exceeds the set value" on page
•
Dryer fan
(see "The dryer ventilation does not function, no water inflow when water cock opened" on page 9
"The dryer ventilation is too weak" on page
•
Dryer heating element
7.2 The dryer ventilation does not function, no water inflow when water cock opened
•
Start the machine in manual mode (see the Operator Manual). Check the current on X9 and X10 connections on the
power PCB. If no voltage can be registered, replace the power PCB. Otherwise, the ventilation has been connected
wrong or is defective.
