Abstract
A holder (10) for refilling an ink jet printhead (11) comprises a box (21) and two covers (22, 23), pivoted upwardly on the box (21) for being rotatable reciprocally and with respect to the box (21). A first cover (22) is provided for positioning and locking the printhead (11) into the box (21). A second cover (23) is superimposable to the first cover (22) and is provided with a seat (30) for being coupled with a refill cartridge (34) so as to refill the printhead (11). A short tube (31) is mounted in the second cover (23) inside the seat (30) to allow ink to pass from the cartridge (34) to the printhead (11) for refilling the latter. Pivoting of the two covers (22 and 23) allows simple and exact positioning of the same covers with respect to the printhead (11), first to lock it into the box (21) and then to fill the printhead (11) with ink.
