Trouble Shooting
5.2 The film does not transport correctly
• Check the positioning of the racks in the machine and make sure that the
latches are closed.
• Check the roller racks: Position of the guide elements, rollers are in correct
position and are not loose, flat springs are not bent, all gears are in place.
• Motor runs: The worm gear of the drive shaft should be secured with a splint
to avoid twisting. Check the screws and positioning of the chain and chain
wheel.
5.3 Scratches, pressure marks, dirt on film
• Straight scratches in the infeed direction indicate faulty guide elements.
Check each rack and straighten up the guide elements. If mechanically dam-
aged, replace the guide elements.
• Pressure marks caused due to dirty or damaged rollers. Check rollers for visi-
ble damage. Rubber rollers sometimes swell up. Replace defective rollers.
4.3 Developer temperature too low
• Check circulation pump. Air lock in the circulation pump: Ventilate the pump.
See Page 8 in the Operator Manual, 1F8039. If no circulation can be
detected: Check wiring of circulation pump; pump possibly defective.
• Bath is not heated: Check temperature safety switch on heat-exchanger.
Check heating element: Current flow resistance: 120 V, 400 W heater = 36
ohms.
• Check temperature sensor (see 4.2).
• If no error can be found then electronic is possibly defective.
4.4 Developer temperature too low, fixer temperature too high
• Air lock in the circulation pump: Ventilate circulation. See Page 8 in the Oper-
ator Manual, 1F8039.
4.5 Removing the turning knob
• Pull the toggle off the knob by help of a flatnose pliers.
• Open the screw of the collet (Attention: don’t loosen completely) and pull the
knob out.
• When reinstalling the knob turn axis on circuit board to end position counter
clockwise. Install the knob so that the pointer is at position of “Manual
pumping”.
4.6 Calibration of developer temperature
Deviating temperatures within +/- 1.5°C can be calibrated by a potentiometer on
the circuit board. It can be reached after removing the turning knob (see page on
right hand side) from above. Turning clockwise decreases the temperature.
5 Film defects
5.1 Films will not dry
• No air comes out of air channel: Check wiring of dryer fan, fan is possibly
defective.
• Cold air comes out of air channel: Check wiring of heating element in the air
channel, heating element possibly defective. Check heating element current
flow resistance: 110 V, 900 W heater =12 ohms.
• Hot air comes out of air channel, but the film is still not dried to satisfaction.
Check chemicals and film type. The transport speed of the machine can be
reduced to increase drying time (see 3.7).
