Take the following precautions when cleaning ink from around the nozzle.
Face the end of the print head downward and pour makeup onto the dirty part and clean while catching the makeup in a
(1)
beaker.
Do not pour the makeup over this section.
Wipe the print head clean with wiping paper
dampened with the makeup.
*This figure is an image of UX2 series. There are some difference between UX2 and UX/RX2, but basic structure is same.
After cleaning, thoroughly wipe the print head with wiping paper and allow it to dry.
(2)
・Thoroughly dry the nozzle orifice, charge electrode, deflection electrode, and mounting base and fringe of the
gutter. Make sure that the parts are sufficiently dry before starting the next operation. If operated while wet,
the printer will not start normally.
・While the print head is wet, do not orient its end upward.
Do not immerse the print head in the makeup.
(3)
When printing is frequently performed or the distance between the print material and the print head is short, ink splashes
(4)
may stain the end of the print head and the print head cover. If this condition is left unresolved, the staining will be worse,
resulting in a print error or emergency stop. If a print error or emergency stop frequently occurs due to staining caused by
ink splashes, stop the operation in progress and clean the end of the print head (around the nozzle, charge electrode,
deflection electrode, mounting base and gutter) and the print head cover. Perform this operation in addition to the
cleaning at the end of each day's work.
Air purging of the print head is effective against staining due to ink splashing. See the "Print head air
purge(*1)".

[ iv ]
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 "Cleaning the Gutter（*1）" 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.
