7.5 Film defects
7.5.1 Films will not dry
• Check the set dryer output (“99” corresponds to maximum, that is full heating output)
• No air comes out of air channel: check the connections of the fan, e. g. fan defective
• Cold air comes out of air channel: check the connections of the heating element in the air
channel, the heating element may be defective (resistance must reached approx. 45Ω)
•
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
7.5.2 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
7.5.3 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 damaged, replace the guide elements
•
Pressure marks caused due to polluted or damaged rollers. Check rollers for visible damage.
Rubber rollers sometimes swell up. Exchange defective rollers
