Solution
Check to make sure that you have
installed the ribbon correctly. For help, see
"Loading Thermal Transfer Ribbon" in
Chapter 2.
Install ribbon with shiny side facing the
printhead. See "Loading Thermal Transfer
Ribbon" in Chapter 2.
Set the switch for the type of media you
are using. See "Configuring the Serial Port
for Communications" in Chapter 1.
Replace the platen roller or printhead.
Switch to approved media or clean the
printhead and platen roller as described in
Chapter 3, "Maintaining the Printer."
Edit the format to ensure that the text fits
on the label. See "Editing Label Formats
and Working With Fields" in Chapter 5 for
more information.
Solution
Make sure the printer's serial port settings
match those of the host. Print a software
configuration label to check settings. See
"Setting the Media Sensitivity Number" in
Chapter 2 for the procedure.
Check the connections at both ends or
replace the cable. See "Connecting the
Printer to Your System" in Chapter 1 for
cable information.
