Filter for use in an inkjet printer

摘要

A common problem in vertical inkjet printers is that an air bubble (18) is formed within the filter and so preventing correct operation of the printhead. Accordingly, there is provided a filter (13) for use in an inkjet printer comprising: a housing (10) having an inlet (11) and an outlet (12); a filter element tapered towards the outlet for, in use, removing unwanted substances from ink flowing through the housing: and a bleed tube (15), having an inlet (17) disclosed on the inlet side at the tapered end of the filet element, for removing trapped air from the inlet side of the filter element. <IMAGE>
