Troubleshooting Guide.Troubleshooting Guide.
Please use the following flowcharts to help you to diagnose what is wrong
with your printer.
When the flowcharts call for a product to be returned to PC-PoS, please
contact PC-PoS before the unit is sent back.
Some of the following flowcharts discuss changing the Dip switch settings
so that they are appropriate for the intended application. If you are not fully
conversant with doing this then either contact your local dealer or contact
the PC-PoS technical support department nearest to you.
These flowcharts are intended as a basic fault-finding guide only and we do
not encourage any repair to the internal mechanisms or electronic
components by non- PC-PoS technical staff as this will render the warranty
invalid. If you have any questions regarding this matter then please contact
PC-PoS.
