dust scattering.
• The using environment of this printer is from 20 to 30°C (68°F to 86°F) in temperature and from 35 to 65 %
in relative humidity. Avoid the use of this printer at a temperature and humidity higher or lower than the
indicated ranges.
4. When the printer is not used for a long period
When the printer is not to be used for a period of one week or above, perform the cleaning of the heads and
nozzles and the ink discharging channel before storing this printer.
When cleaning, be sure to provide adequate ventilation and be sure to wear the supplied protective
glasses and gloves.
When ink is mixed with water or alcohol, aggregates are generated. Do not to allow water or alcohol to
deposit to the nozzle surface, around the head, cap, and wiper.
To ensure ink ejection stability, this machine must periodically eject (flush) a small amount of ink
depending on the ink type when it is not used (output) for a long time.
When not using this machine for an extended period of time, execute the [CUSTODY WASH] function,
("When the Machine Is Not Used for a Long Time (CUSTODY WASH)" Chapter 4 of Operation Man-
ual) and turn off only the power button on the front panel. The main power switch on the right side
should be on (in the state of |) and the outlet should be inserted.
Never disassemble the machine. Failure to do so may cause electric shock, fire or damage.
Make sure that no moisture enters the machine. If the inside gets wet, it may cause electric shock, fire
and damage.
Before cleaning, turn off the power switch and disconnect the power cable. It may cause an unex-
pected accident.
Do not use chemicals containing benzine, thinner or abrasives. The cover surface may be altered or
deformed.
Do not lubricate the machine with lubricating oil.

7. Daily care
(1) Surroundings of the heads ("Cleaning the Ink Head and the Area around It" Chapter 5
of the Operation Manual)
• Maintenance washing liquid kit for solvent (SPC-0369) / Cleaning solution bottle kit A29 (SPC-0137)
1Move the carriage.
• Refer to the Step 1 to 4 of Chapter 5 “Cleaning the
Ink head and The area around It” of the operation
manual to perform the operation.
2Soak the clean stick or the waste cloth in the maintenance cleaning liquid and wipe
off an accumulated ink on the side of the head and on the bottom surface of the
slider.
• Never rub the nozzles.
• When possible, use the cleaning stick (SPC-0527) for cleaning around the head/ capping station/ wiper.
Using the other cotton bud may attach lint, then it may damage the machine.
• Be sure to perform maintenance for the ink cap and the wiper of capping station every day. If you leave it
dirty, dirt may adhere to the nozzle surface, or, dust and dry ink may be rubbed against the nozzle. It may
cause discharge defect.
• Clean the bottom of carriage every day so that it will not get dirt from inks or dusts. If you leave it dirty, dust
and dry ink may be rubbed against the nozzle at wiping operation when performing head cleaning.
• When you clean the carriage bottom surface, fully be careful not to rub the nozzle surface.
• The heads and their surroundings are the parts most liable to be tainted in this machine and if
tainted, it could cause adverse effects to the functions of the machine and the results of the printings.
Moreover, as the head itself uses very fine mechanisms, sufficient precautions are required for the
care and maintenances.

(4) Media press (“Cleaning the Media Press” Chapter 5 of the Operation Manual)
When the cut dust of the media and other dusts accumulate between the media holder and the platen, it could
cause the risks that the transfer of the media could not be performed properly or such dusts stick to the noz-
zles and this could interfere the proper printings. You are recommended to clean it frequently.
(5) Media sensor ("Cleaning the Media Sensor" Chapter 5 of the Operation Manual)
The media sensors are located on the platen in the backside and the bottom surface of the head.
If the dusts and ink accumulate on the sensor, it could cause false detection of the media or the register mark.
