Cleaning Card Procedure
If printing with direct thermal media, thermal transfer media with wax/resin ribbon combinations, or if the
Cotton Swab technique was not successful, clean the printhead as follows:
1) Open the printer. Wait briefly for the Printhead to cool.
2) Remove media and ribbon then place a Cleaning Card under the Printhead (part number 70-2013-
01).
3) Close the cover then press the Button to initiate cleaning.
4) After the cleaning card has been run through the printer, reinstall media (and ribbon, if needed).
Plug in and turn ON the printer. Run a few sample labels and examine them. If streaking is still
present, use the Cleaning Film Procedure, below; otherwise, this completes cleaning.
