System temperature too high to operate.
Electronics temperature has exceeded 60°C. Reduce environment temperature.
If ambient temperature is not exceeding 50°C, replace the Main Circuit board due to faulty on-board
temperature sensor.
Pressure sensor is measuring ~40 PSI with the jet off. Should be ~ <4 PSI for natural effects.
Ink inlet is clogged and pressure is trapped on the transducer. Place the printhead over a beaker and
enable the bleed valve for 30 seconds to bleed pressure off from the Transducer. Clean the green ink
feed tube and venturi inlet to dissolve clog.
Pressure sensor or pressure sensor cable are damaged. Replace to resolve.
Main PCB Board pressure measurement circuitry damaged. Replace main board.
Printhead temperature too high to operate.
Printhead temperature has exceeded 60°C. Reduce environment temperature.
If ambient temperature is not exceeding 50°C, replace the Printhead Umbilical due to faulty
temperature sensor.
Indicates a printhead fault detected by the High Voltage detection circuit and the Phase Detection
circuit.
Allow head to dry for 24 hours and repeat test. If fault occurs again, replace the umbilical.
Allow head to dry for 24 hours and repeat test. If fault does not immediately occur, disable the
“Printhead Fault” from the Technician: Print screen.
"Printhead not detected."
Indicates that the printhead is not detected. This is determined by reading its temperature; if the
temperature cannot be read or if the temperature is less than -10 degrees C (+14 F).
Check Printhead Connection on J27.
Check on screen Printhead Temp. If Temp is under -10C, the head requires external warming to
operate properly.
Indicates that a photocell print trigger occurred while a message being printed
Add debounce (Peripherals : Photocells screen) until issue resolves.
Adjust gain on Photocell sensor to prevent double triggering.
Move photocell closer to the Printhead.
