If Colors are Uneven
Mixing the Ink by Shaking the Ink Pouch
If ink components precipitate in the ink pouch, colors
may be uneven (unevenness in printed colors). If colors
are uneven, rst remove the ink pouches, and shake
them gently.
If uneven color issues are not resolved even after shaking the ink pouches, perform light choke cleaning.
Light Choke Cleaning
If printing is not performed for several days, printed colors may become unstable or uneven, e.g., when color
density is inconsistent, even if the same data is printed with the same settings. In such cases, perform light
choke cleaning. This will stabilize printed colors by agitating the ink.

Before shaking, wipe off any ink from around the mouth of the ink pouch.
If you do not wipe o the ink, it may splatter when you shake the ink pouch.
When you have nished agitating the ink, reattach the ink pouch immediately.
If you take time to reattach the pouch, it will adversely aect the ink path.
When installing an ink pouch and returning the ink pouch holder to its original posi-
tion, raise the ink holder rmly until it clicks into place.
Ink will leak if the ink pouch holder is not returned to the correct position.
Light choke cleaning consumes a lot of ink, and overly frequent use may damage the print heads them-
selves. Avoid using it more than necessary.
