Permanently Occurring Hardware Errors

Error message
Printhead thermistor defect
Voltage error
V
BAT
24 V
24 V TPH
Table 2
Possible solutions
Check electronic connection between the CPU circuit board and the motor
Check the drive mechanism
Exchange the CPU circuit board
Exchange the motor
Check connectors of the printhead
Inspect the printhead cable for damage
Exchange the printhead
Exchange the CPU circuit board
Check the cable connection between the CPU circuit board and the control panel
Swap out the display
Exchange the CPU circuit board
Check the connection from the printer to the computer
With Ethernet connections check the validity of the IP address and the subnet
mask.
Check, and if necessary change, the interface cable
In case of complete outage exchange the CPU circuit board
Check if the peripheral device is connected via programming
Ensure the USB cable of the peripheral device is working and exchange it if
necessary
Test the peripheral device
Exchange the CPU circuit board
Failure of device functions
Cause
Thermistor of the printhead
broken
Voltage of the battery on the
CPU circuit board too low
24 V too little
24 V too low for printhead
Hardware errors
Solution
Exchange the printhead
Exchange the CPU circuit board
Check voltage at measuring point +24V
 Fig. 18 on page 26:
• Voltage too low:
Swap out power supply
Voltage sufficient:
•
Exchange the CPU circuit board
Check voltage at measuring point +24V TPH
