1.2.5. Cautions on Operating Time When Unit Is in Service
(1) Cautions when the unit is repeatedly stopped immediately after the start of
operation
If you repeatedly stop the unit immediately after the start of operation, automatic nozzle cleaning at
shutdown will cause the ink in the unit to gradually become thinner. For stable operation of the unit, operate
it for a given amount of time or more once it is started (= in the ink ejection state). During the operation, the
ink viscosity is adjusted automatically and returns to the initial value. The required operation time varies
depending on the ambient temperature or ink types used. See the handling guidance of each ink for details.
(2) Cautions when daily operating time is relatively long
This unit emits ink during printing, so the outside and inside of the print head cover will become dirty with
accumulated ink spillage during operation. To prevent printing defects due to this ink accumulation,
periodically check the head cover and clean it where necessary.
