13 Remove the HEAD from the ADAPTER and fix the new
HEAD to the ADAPTER.

bottom left corner of the ADAPTER.
Use the 2kgf·cm torque driver (ST-056) to
tighten up the screws.
14 Install the HEAD to the head carriage and fix the 3
screws temporarily. Then, fix the SPRING and tighten
up the 3 screws in order as shown in the figure.
Use the 2kgf·cm torque driver (ST-056) to

15 Connect the 2 flexible cables to the HEAD BOARD.
Do not connect cable to the wrong connecter.
16 Fix the HEAD BOARD COVER temporarily.
The HEAD BOARD COVER should be fixed to
prevent the ink from dropping on the HEAD
BOARD when fixing the INK DAMPERs. It is
not necessary to fix the cover with the NYLON
RIVET, because the cover needs to be
removed for the HEAD ALIGNMENT.
