Powerful Cleaning'

Procedure
When powerful cleaning is not effective
If problems such as dot drop-out persist even after you have performed powerful cleaning
several times, perform "manual cleaning." Such cleaning can be effective when carried
out periodically, according to the frequency of use.
If Colors Are Uneven
Light Choke Cleaning
Perform this cleaning when printed colors are unstable or uneven, e.g. when color density
is inconsistent, even if the same data is printed out with the same settings. This will
stabilize the output colors by agitating the ink.
