METHODS AND APPARATUSES FOR USE IN INKJET PENS

摘要

Methods and apparatuses are provided for use in inkjet pens (200, 300, 400). One method includes, during an initial stage of pen life (604), drawing ink (108) from an ink reservoir (106) though a standpipe (100), and, during an extended stage of pen life (606), allowing external air (204) to enter into the standpipe (110) through a standpipe bubbler (202,404) and drawing ink from within the standpipe (110) and, if at all, only insubstantially from the ink reservoir (106).
