Reverse these steps to reinstall the thermal head, then perform the Chapter 9 procedure
“Adjusting for best print quality” on page 9-14. Route the grounding strap so that it does
not interfere with the thermal head lift belt.
Warning Do not disconnect the ground strap from the back of the thermal
head; only disconnect it from the head lift motor bracket. Not
reconnecting the ground strap will damage the thermal head upon
power-up.
