a waste ink tank of some description
(I used a spare ink reservoir bottle)
some electricians insulating tape
a piece of 4mm outer diameter tubing of at least 20 cm length.
(note: outer diameter is the maximum measurement (to the outer surface of the tube). The inner diameter would be the diameter between the inner walls of the tube)
a glue gun is optional but makes life a lot easier!
Oh and Unplug your printer from the power!
(Just in case someone actually isn't thinking at all!)
