Resetting the Factory Default Values

Sometimes, resetting the printer to the factory defaults may solve some problems. Refer to the

four-flash sequence in Feed Button Modes on page 70 in this section.

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 70 in this section.

The printer will print ‘Now in DUMP’ (see below) and advance to the top of the next label.
