An ink cartridge component comprises a body member having a sump portion
for supporting a print head and a peripheral wall portion extending from
the sump portion. The peripheral wall portion and the sump portion define
a volume forming an ink chamber of the ink cartridge. A recessed region
is defined at a junction between the peripheral wall portion and the sump
portion, the recessed region, in use, underlying a carrier carrying the
print head. The recessed region facilitates flexing of the carrier when
an ink cartridge including the component is inserted into a cradle of an
ink cartridge carriage.
