Ink Cartridge
The ink cartridge used with the Micro-Z Inkers is a DM-2
pneumatic ink cartridge. DM-2 cartridges have a
polypropylene reservoir (sealed at the bottom by a thin
membrane) and a small Teflon
tube encased in a stainless
steel needle. When the cartridge is opened, the needle
punctures the membrane to provide ink flow through the
Teflon
tube.
Each cartridge holds 1.0 grams minimum of ink and can
produce a wide range of dot sizes. Dot size is controlled
by changing the duration of the air pulse into the cartridge
reservoir, which determines how much ink is forced
through the Teflon
tube to create the ink drop at the needle tip. For more information see
Section 5 “Ink”.
