Troubleshooting Procedure 6. – No Serial Communications
Step Check Item
1. Ensure that the proper serial communications cable is
connected between the printer and the host. Turn the printer
ON and send a label to the printer. Did the label print?
2. Compare the desired label format with the format produced. Is
the label format correct?
3. Print a configuration label (see page 6–2). Check the label for
the printer's current communications parameters. Do these
parameters match those of the host device?
4. Send a label to the printer with the printer in the hex dump
mode. Setting the printer to the hex dump mode is
accomplished by:
(a) Selecting the hex dump mode from the Secondary
Operator Panel (see the LP+, IGP/PGL, IGP/VGL Setup
Guide , Chapter 3).
(b) Sending a label to the printer after printing an IGP/FGL
configuration label (without turning printer OFF)
Was hex data printed on the label?
