Installation environment and Notes on cleaning
•Use this printer in clean (less dust) environment. The use of fan and ventilator might be
cause of dusty environment.
They brow dust up dust around the printer.
•As using UV curing ink, install this printer in a well-ventilated area.
•Working environmental temperature is 15 to 30°C (59 to 86°F). Avoid using at lower or
higher than this.
Notes on cleaning
•Never disassemble the device. Disassembling the device can result in
electric shock hazards and breakage of the device.
•Prevent moisture from entering inside the device. If the inner part of the
device becomes wet, electric shock hazards and breakage of the device
can result.
•Conduct maintenance works after turning off the power switch and detach-
ing the power cable. If not, unexpected troubles can arise.
•Make maintenance after the UV lamp has been sufficiently cooled, or burn
injury may occur.
•Do not use benzine, thinner and chemical agents containing abrasives.
Such materials can deteriorate or deform the surface of the cover.
•Do not apply lubricating oil or the like inside the device. Such materials
can cause the printer mechanism to fail.
•UJF-605C is a printer that uses ultraviolet ray curing ink (UV ink).. When
implementing the daily care, must wear supplied goggles and gloves.
•In case water or alcohol mixed into the organic solvent ink, flocculation
would be occurred. Be sure that not adhere water or alcohol to not only the
nozzle and also near the head, the cap, wiper and so on.

Maintenance for frame components
If the frame components of the device have stained, dampen a piece of soft cloth with
water or neutral detergent diluted with water, squeeze it and wipe the frame components
clean.

In Case Sefective Printing Is Not Resolved
When the station interior is severely contaminated or defective printing is not resolved
after executing the head cleaning function ( Operation manual P.2-20).
Clean the suction nozzle and cap using the cleaning kit as follows,
Washing liquid, Gloves, Cleaning swab, goggles
•When cleaning the ink station and head, be sure to wear the supplied
goggle and gloves since you may get ink in your eyes.
•Do not use alcohol or water.
•Do not move the carriage out of the capping station by hand. Use the
appropriate operation key to move the carriage.
The examples of defective printing
These following examples indicate improper head (nozzle) firing by dust, which effect
printing. Confirm the nozzle condition periodically before or during outputting not to use in
such as this condition. The nozzle condition can be confirmed with [test print] in this plotter.
