TROUBLE SHOOTING
This section gives solutions to some printer problems you may have.
General Problems
No LED lights up on control panel when switched on –Make sure that the
power supply cables are correctly plugged into the printer, the power adaptor
and to the power outlet. Make sure that power is supplied to the power outlet.
If a switch or timer controls the outlet, try using another outlet
Printing Problems
Nothing can be printed with ERROR LED flashing – Most possible cause
for the flashing Error LED is that the printer has been printing for quite a
period of time and the print head temperature become too high. After few
minutes under normal ventilation, the print head should be able to cool down
and the Error LED will stop flashing. Printing will resume after cooled down.
If this is not the case, contact a qualified service person.
