Troubleshooting and Error Treatment

6.1 

Failure of Device Functions

Functional error

Possible remedy

Medium is not transported

Check electrical connections between PCB CPU and motor

Check drive mechanism

Replace the PCB CPU

Replace the motor

No print image with medium 
transport

Check plug connections at the printhead

Examine printhead cable for damage and replace if necessary

Check the automatic ribbon saver 

Replace the printhead

Replace the PCB CPU

No display function

Check cable connection between PCB CPU and control panel

Replace the control panel

Replace the PCB CPU

Communication via an interface 
is not functioning

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

A peripheral device is not 
functioning

Check whether the peripheral device is activated via programming

Check the USB cable of the peripheral device and replace it if necessary

Check the peripheral device

Replace the PCB CPU

Permanent Hardware Faults

Error message

Cause

Fault recovery

Printhead thermistor broken

Thermistor at the printhead defective

Replace the printhead

Voltage error

V

BAT

Voltage of the battery on the PCB 
CPU is too low

Replace the PCB CPU

24 V

24 V too low

Check voltage at measurement point +24V  

 Figure 27 on page 33:

• 

Voltage too low:  
Replace the power supply unit

• 

Voltage is correct:  
Replace the PCB CPU

24 V TPH

24 V for the printhead too low

Check voltage at measurement point +24V TPH 

 Figure 27 on page 33:

• 

Voltage too low:  
Replace the power supply unit

• 

Voltage is correct:  
Replace the PCB CPU
