3. Disengage the Leveling Cam; see Section 2.2.1.
4. Plug in and turn ON the printer. Press FEED several times to normalize ribbon and label tracking.
(If lateral movement is excessive, this must be corrected before proceeding-- typical causes
include an unlatched printhead, uneven printhead pressure, a worn platen or worn platen
bearings.)
5. Observe the ribbon for rippling and bagging as it travels from the Ribbon Supply Hub to the
Printhead Assembly. If smooth, proceed to Step 6; otherwise, loosen the Idler Screw then, while
repeatedly pressing FEED, rotate the Idler Cam until the ribbon is smoothly dispensed. Tighten the
Idler Screw and feed several more labels to verify adjustment; repeat if necessary.
