Algae
1.1 Excessive algae growth in water tank
Algae growth inside the water tank is not only annoying, it causes increased cleaning work and leaves residue on the films.
When algae growth increases, countermeasures are necessary:
•
When work has been completed at the end of the day, drain the water out of the machine.
•
Clean the dryer water rack regularly. Use a soft sponge and soap to remove residue from the rollers.
•
Install a particle filter system in the fresh water supply for the processor.
•
If no other solutions can be found, then the use of anti-algae-agents can be a great improvement (automatic
dispensers work the best). However, cleaning agents containing chlorine may corrode the rubber rollers and high-
grade steel in the tank area (check before use).

General
2.1 The mains switch is "on," but there is no function
•
Ensure that the electrical socket has a power supply.
•
Check the machine fuses.
Use only the original manufacturer's replacement fuses. These fuses are optimized for use under
existing conditions.
•
While the power switch is on, check the following component: Voltage on contact of main switch. If there is no voltage,
replace the respective component.
2.2 No display, but the circulation pumps are running
•
Check the entry current of 5 V on contacts no. 7 and 8 of 8-pole-plug X23 from the control unit's PCB. If voltage is
present, then replace the control unit.
•
Check fuse (5 A) on the power PCB.
•
Disconnect the temperature sensor developer bath (X25) and check the display again.
•
Disconnect the temperature sensor dryer (X24) and check the display again.

Drive
3.1 Machine does not start automatically
•
When the machine is switched on, place a film in the infeed until it reaches the pull-in rollers. If necessary, move the
film sideways to activate the light barrier. If the display shows two bars with decimal points, then the light barrier is in
order.
Check each of the four eyes on the light barrier. Each eye must start the machine. If they do not, then replace the light
barrier. Check the connection of the light barrier. If there is no reaction on the display, then replace the light barrier.
Eventually the control unit has be changed.
•
The display shows "E1": The cover switch is not actuated by the latch on the cover. The cover switch has no current
passage when activated. Replace the cover switch.
•
The developer temperature button is flashing:
3.2 Machine does not stop automatically; the motor and fan run continuously
•
The display is flashing: Control is in the manual mode. Switch back to automatic mode (see the Operator Manual).
•
The display continuously shows two bars with decimal points: The light sensors on the light barrier are dirty or the
light barrier is defective. Clean with a soft cloth. If necessary, remove the light barrier to clean it. If the switches are
defective, the machine can still be used in the manual mode (see the Operator Manual).
•
The PCB is possibly faulty. Replace it.
