5 Film defects
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.
6 Replenishment
6.1 Replenishment pump does not work or works insufficiently
7 Dryer
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
7.2 Dryer ventilation does not function, no water inflow when water cock
opened
• 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.
Install valve-insert correctly:Pay attention to flow-through di-
rection!
