How to Bleed an Ink Filter
NOTE
The same syringe can be used to bleed all the ink channels if they are done in succession. The
syringe cannot be stored and reused as the ink chemistry will degrade the syringe. If only some
of the ink channels require bleeding, discard the syringe immediately after finishing those
channels. Do NOT reuse it on other ink channels at a later date.
