System Error Codes
SE Code: 15.06:00 - Temperature error detected
Problem Description:
There is a mismatch between the temperature detected by the Drying IR Sensor and the amount of
electrical power the Drying System is receiving
Corrective Action:
The ink density is too high, check the User´s Manual for the recommended ink density levels.
Check if the input voltage is in the range of 198v to 205v, ensure the ambient temperature is higher
than 20C for the correct functioning of the printer.
Check if the substrate loaded on the printer is too transparent or reflective for the IR sensor to detect
the surface temperature. Check this by loading another type of substrate.
Check that power is going to the IR Sensor, a good indication of this is the blue LED lights if the
sensor is pointing to an object warmer than 30c
Check if the Dryer IR sensor is dirty and requires cleaning, use the cleaning procedures described in
the User’s Guide while observing all safety precautions while working in the area of the heaters.
Check the position of the IR sensor is correct, if it is pointing to a position other than the substrate this
will cause an error.
Perform the IR sensor check 1.8.1 Heating and Curing temp Page 195, to check the values being
detected by the IR sensor. Replace the Dryer IR sensor if required Page 496.
Replace the Heaters Control Assembly Page 465.
If there is power going to the heater, but the heater does not come on, replace the heater
Page 498.
Check the voltage supplied to the Printer is inside the Printers functional specifications.
Check the quality of the AC line going into the printer.
