Use a blunt tipped tool to press the release tab on the right side and then the left side of the
printhead. The tool diameter can be from 0.10 to 0.15 inches (2.5 to 3.8 mm).
Insert the tool into the ribbon frame's printhead release access (the round) opening. Push
the release tab and gently pull the printhead bracket down.
