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 77 in this section.
Communications Diagnostics
If there is a problem transferring data between the computer and printer, try putting the printer

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