Cotton Swab Procedure - Datamax M-Class Mark II Maintenance Manual

2.1.1.1

Cotton Swab Procedure

This procedure is recommended if using direct thermal media, or thermal transfer media
with a wax ribbon.
1. Perform the Preliminary Cleaning Steps, as described in Section 2.1.1.
2. 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.
3. Allow the printhead to dry. Reinstall media (and ribbon, if needed). Lower and latch
the Printhead Assembly. (If necessary, perform a Media Width Adjustment; see Section
2.3.) Close the cover. Plug in and turn ON the printer. Run several sample labels and
examine the print quality. If streaks are still present, see Section 2.1.1.2; otherwise,
this completes the procedure.
