When assembling the maintenance base assembly, it should be
installed after moving the CR unit away from the capping
position. If it is installed with the CR unit in the capping position,
it makes contact with the cap flag on the head surface as in the
figure below, and there is a possibility that the head surface could
be scratched.

When assembling the maintenance base assembly, if it is not
raised up securely to the screw tightening position and the screws
tightened, it will cause a drop in the tight fit between the cap and
the head, resulting in leaking ink and leading eventually to
skipping of dots, so adequate caution should be exercised.
