Restore the Printer to Operation

1. Inspect the light brown area of the printhead for smudges or fingerprints. If necessary, gently
clean the light brown area with a soft, lint-free cloth (or a cotton swab) moistened with isopropyl
alcohol, or use a Cleaning Pen (P/N 203502-001).
2. Install the ribbon and media (e.g., paper, label, or tag stock material).
3. Close the pivoting deck and rotate the deck lock lever fully counterclockwise.

5. Plug the AC power cord into the printer and the power source.

Diagnostics for Fatal Error:

If the printer stalls with an LCD message that starts with "Fatal Error:", reboot the printer and continue. If
this situation persists, invoke the diagnostic Auto Dump that will capture the failure dump in a flash file that
can be later uploaded from PrintNet Enterprise Suite or SD memory card and sent to Printronix Customer
Support Center (see Printronix Customer Support Center page 318) for further analysis.
This diagnostic option must be enabled for the printer to capture the information. To perform this diagnostic
do the following the procedure:
1. Enable the Tools > Diagnostics > Auto Dump option.
2. When the failure happens, reboot the printer and wait for it to power up again.
3. Under System > Flash File View, check to see if files 'autodmp1' or 'autodmp2' are present.
4. If present, use PrintNet Enterprise Suite to upload these files to your host computer. Alternatively, use
the function System > Flash File Edit > Copy to SD to copy the file onto an SD memory card.
5. Contact Printronix Customer Support Center and send them the files and the printer's configuration
printout. Refer to the PrintNet Enterprise Suite User's Manual for instructions to accomplish these
tasks.
