Notification that supply is impossible because the oil plug was broken, but genuine was arranged but this machine is old. I ordered it on the HP by finding equivalent products at this HP, it was just fit. I'm glad that it was good.
I think that the construction is good, such as screws. It is good to have a version that does not exist because the air bleeding hole becomes an obstacle in a tank that puts some pressure on it. The 'OIL' seal on the surface seems to be peeling off and there is somewhat concern.
