Troubleshooting
3.3 The drive motor does not run
•
The display shows "E1" or "E3": See the Operator Manual for descriptions of the error messages.
•
If current can be registered on the motor, then the motor is defective. Replace it.
•
The dryer fan runs, but there is no voltage on the motor: Replace the power PCB.
3.4 The display shows error message "E2"
•
Check the plug-ins between the main drive motor and the power PCB. If "E2" appears again, then replace the main
drive motor. In rare cases, the PCB causes the error. See the Operator Manual for descriptions of the error
messages.

Baths
4.1 No circulation in the developer or fixer baths
•
The circulation pump runs but no circulation can be registered. There is an air lock in the heating and circulation
system. Ventilate the system (see the Operator Manual).
•
There are particles in the pump chamber. Drain the bath before opening the pump. The pump chamber can be easily
opened by removing the four screws. After cleaning, close the pump chamber and ensure that the seal is correctly re-
inserted and not damaged.
•
The pump does not run. Check the voltage on the connections X3 and X4 of the power PCB. If no voltage can be
registered,
see "The mains switch is "on," but there is no function" on page
pump.
4.2 The developer bath temperature is not reached
•
No circulation:
1) The circulation pump has no current or is defective.
2) There is air in the circulation system.
•
Check the temperature safety switch on the heat-exchanger. For
temperatures up to 90 °C, the temperature limiter must have current passage.
•
Check the heating element: Current flow resistance should read
approximately 66 Ω.
•
Check the temperature sensor: Voltage at X25 on the control unit between
pin 3 (green) and pin 2 (brown). The value should read 0.32 V at a
temperature of 32 °C.
•
Increase the temperature and check the current on the control unit of clip X13.
The voltage should be between the mains and 60 Volts. If it does not, then
replace the electronics.
4.3 The developer bath temperature is higher than the set temperature, the display shows two crossbars, the
developer temperature button blinks
•
See above
•
Check the current on power PCB at clip X13. There may be no current. If current is registered, replace the
electronics.
4.4 The developer bath temperature too high or too low (display shows values of 20 °C or 42 °C)
•
Check the temperature sensor. The sensor is either not connected or defective.
4.5 The calibration of the bath temperature / actual bath temperature is different from the displayed value
•
The differences between the displayed temperature and the measured value in the developer bath can be adjusted.
An adjustment may be necessary; for example, after replacing the bath temperature sensor. A calibration has to be
done if the difference is higher than +/- 0.5 °C. The adjustment range is +/- 2 °C.
