Cotton Swab Procedure

This procedure is recommended for printers using direct thermal media, or thermal transfer media with a
wax ribbon.
 Perform the Preliminary Cleaning Steps, as described in Section 2.4.1.
 Turn 'Off' and unplug the printer. Using a Cotton Swab moistened (not soaked) with isopropyl
alcohol, gently clean the entire Printhead surface, paying special attention to the Burn Line, until all
build-up is removed.

 Allow the printhead to dry.
 Reinstall media (and ribbon, if needed). Lower the Printhead Assembly and rotate the Printhead Latch
to the locked position. (If necessary, adjust the Leveling Cam.) Close the cover. Plug in and turn 'On'
the printer. Run several sample labels and examine the print quality. If streaks are still present, go to
Section 2.4.1.2; otherwise, this completes the procedure.
