The invention relates to the use of a flexible porous
member and a thermal setting adhesive to create a seal between
a printhead and the housing of an inkjet printer cartridge
which contains the ink supply. Referring to Figure 2, a
porous member 36 is located between surface 26 of cartridge 10
and the printhead 14 (Spec. at 8, lines 5-11). As is also
apparent from that figure, the porous member has a slot 35
therethrough for connecting one end of cartridge recess 30
(which receives ink from ink chamber 11 via outlet 16) to the
interior end of the nozzle passage 37 in the printhead. As
shown in Figure 4, prior to assembly of the cartridge and the
printhead, surface 31 of porous member 36 (excluding slot 35)
is provided with thermosetting adhesive layer 38, which is
insoluble in components utilized in ink (Spec. at 7, lines 20-
25). During assembly, the porous member is positioned against
surface 26 of the cartridge and the temperature raised to
