It is recommended that if you have recently come into
ownership of a second user Epson Stylus Pro 9800 then
you should assume that the counter values or service
life levels are incorrect and choose the most thorough
procedure detailed above. The reason for this is an
increasing number of printers being "reset" without
the actual parts being replaced or inexperienced owners
trying to repair or replace parts incorrectly. In one
such case a part was removed and replaced incorrectly
causing a serious ink leak which was luckily caught
early due to the undertaking of an thorough maintenance
procedure, but unfortunately extensive damage had already
been caused to the chassis and maintenance tank area.
