Table 12. Printer Problems and Solutions
This message informs the user that the printer has received
data, but no valid commands were found. This typically occurs
when an incorrect Active IGP Emulation or SFCC was selected.
This message will continue to display until new data is
received or when the printer is put OFFLINE.
1. If the emulation and SFCC are correct, additional
diagnostic information can be obtained by selecting the
desired option under the "xxx Diagnostics" menu, found
in the Application > Control section.
2. After selecting the desired option, run the job again to
obtain the additional diagnostic information.
1. Check the LCD for a specific fault message. Press the
PAUSE key, and if a fault message displays, refer to the
LCD Message Troubleshooting table on page 258.
2. Check for an Out-of-Media condition or missing labels in
the middle of a roll. Load the correct media.
3. Check that the ribbon and label stock are correctly routed.
Load ribbon and label stock correctly.
1. Check that the printer AC power cord is correctly attached
to the printer and to the AC power outlet.
2. Have a qualified electrician test the AC wall outlet for the
correct power range. Locate the printer in an area that has
the correct power range.
3. Check the AC power cord. Replace a damaged AC power
cord or one that you suspect may be bad.
4. Call your authorized service representative.
1. If the serial interface is being used, verify that the correct
serial data protocol is selected to match the host interface
protocol.
2. If Media > Image > Clip Page = Enable, the printer may
have falsely detected a gap, hole, or black mark and then
clipped (discarded) the remaining printable data for the
label. To fix this:
a. Perform Auto Calibrate. See Running Auto Calibrate
page 41.
b. Decrease Sensors > Control > Gap/Mark Threshold
value by 2 or 3 increments. See Gap/Mark Thresh on
page 85.
c. Set Media > Image > Clip Page to Disable and Media
> Image > Label Length to correct physical length
value. See Intro: Clip Page on page 62.
