Resetting the Factory Default Values
Sometimes, resetting the printer to the factory defaults may solve some problems. Refer to the
Communications Diagnostics
If there is a problem transferring data between the computer and printer, try putting the printer in the communications diagnostics mode. The printer will print the ASCII characters and their respective hexadecimal values (a sample is shown below) for any data received from the host computer. To find out how,
There are multiple ways to enter hex data dump mode:
•The ~JD ZPL command
•The dump EPL command
•On power up with the Feed button pressed. Refer to the power off mode procedure in Feed Button Modes on page 96 in this section.
The printer will print ‘Now in DUMP’ (see below) and advance to the top of the next label.
