5.1 Films will not dry
•

Hot air comes out of air channel, but the film is still not dried to satisfaction. 
Check chemicals and film type. If this leads to no solution then the transport 
speed of the machine can be reduced (see 

Processing time, page 14

).

5.2 The film does not transport correctly
•

Check the positioning of the roller racks and ensure that levers are closed. 
Check the gears on the roller racks. Check the positioning of the guide bars 
and roller pressure.

•

Check gears on motor and worm gear of drive shaft.

5.3 Scratches, pressure marks, dirt on film
•

Straight scratches in infeed direction suggest a fault on the guide bars. Check 
roller racks individually and adjust guide bars. In case the guide bars are dam-
aged - exchange.

•

Pressure marks caused due to polluted or damaged rollers. If necessary 
exchange rollers.

7.1 Display shows error message “E4”
Following parts should be checked and if faulty be replaced: 

•

Power PCB (in stand-by no voltage at X12)

•

Temperature sensor

see “Dryer temperature display exceeds the set value” on 

page 42

•

Dryer fan (

see “Dryer ventilation does not function, no water inflow when 

water cock opened” on page 41

 and 

see “Dryer ventilation is too weak” on 

page 42

)

•

Dryer heating element

•

Start machine in manual mode (see 

page 16

). Check current on X9 and X10 

connections on power PCB. If no voltage can be registered - exchange power 
PCB. Otherwise ventilation has been connected wrongly or is defective.

•

Replenishment pump sucks air in. Check hoses and connections.

•

Check eccentric position. Capacity approx. 710 ml/min (850 ml/min with 60 
Hz power mains) at setting to 100%. Minimum setting must not be below 50 
%.

•

Activate replenishment (in the manual mode) and while on, check the volt-
age of connection X6 (DEV) and X7 (FIX) on the power PCB. If no voltage 
can be registered - exchange power PCB.

•

Clean valves inside connection tube of pump.
