Communications Diagnostics

8/4/10 GK420d™ User Guide 980608-001 Rev. C

The following example of a communications DUMP mode printed out. The printout displays

hexadecimal data 00h-FFh (0-255 decimal) with a unique character for each hexadecimal

value displayed above the hexadecimal data.

The blank lines between the lines of data are where serial port and Bluetooth data handling

errors get logged. The errors are:

•F = Frame Error

• P = Parity Error

• N = Noise Error

• O = Data Overrun Error

To exit the diagnostic mode and resume printing, turn off and then turn on the printer. An

alternate method for exiting the diagnostic mode is to press the Feed button as many times as it

takes to clear the printer’s command buffer and print ‘Out of DUMP’ on the label.
