Hardware faults
Possible remedy
Check electrical connections between PCB CPU and motor
Check drive mechanism
Replace the PCB CPU
Replace the motor
Check plug connections at the printhead
Examine printhead cable for damage and replace if necessary
Replace the printhead
Replace the PCB CPU
Check cable connection between PCB CPU and control panel
Replace the control panel
Replace the PCB CPU
Check whether the interface configurations of the printer and computer match
For an Ethernet connection, check the validity of the IP address and the subnet
mask
Check the interface cable and replace it if necessary
If all functionality of the interface has been lost, replace the PCB CPU
Check whether the peripheral device is activated via programming
Check the peripheral device
Replace the PCB CPU
Cause
Voltage of the battery on the PCB
CPU is too low
24 V too low
24 V for the printhead too low
Fault recovery
Replace the PCB CPU
Check voltage at measurement point +24V
