1.2.8. Gutter Cleaning 
 
This unit collects ink from the gutter. At the same time, it sucks in atmospheric gas, dust, and other matter from 
the air. If these substances are mixed with the ink in the gutter, undissolved components in the ink or makeup 
may stick to the gutter. If the unit runs for a long time without the gutter being cleaned, these components will 
gradually accumulate in the gutter. This, together with the ink coming into contact with it, may cause an error 
stemming from a dirty head. 
If this fault occurs, perform the following actions (1) and (2): 
(1)  Clean the gutter and its perimeters with makeup periodically. 
(2)  See the procedures described in the Technical Manual "5.6 Cleaning the Gutter" to clean the gutter and the 
ink recovery route. 
 
If the above actions (1) and (2) do not solve the issue, contact your nearest distributor.
