Requests for Care and Maintenance
This machine is a precision machine equipped with extremely fine mechanisms. Especially, the nozzle sur-
face of the heads from which the ink is discharged is affected even by a slightest attachment of dust or paper
powder and the proper printing results could not be obtained. With a view to using this machine in a better
condition, we would like to recommend performing the following care and maintenance on daily basis.

2. Daily care
(1) Surroundings of the heads ("Cleaning the Head and the Area around It" Chapter 4 of
the Operation Manual)
• Cleaning Liquid Bottle Kit A29 for sublimation dye ink (SPC-0137)
1Move the carriage to the left and open the
maintenance cover.
• Refer to the Step 1 to 4 of Chapter 4 “Cleaning the
Head and the Area around It” of the user’s 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.

maintenance cover.
• Refer to the Step 1 to 5 of Chapter 4 “Cleaning
around the wiper” of the user’s manual to perform the
operation.
2Clean the cap.
• Dip the clean stick into the cleaning liquid for
maintenance and wipe off the cap. Wipe off so that
cleaning solution for maintenance will not remain.

(3) Wiper ("Cleaning around the wiper” Chapter 4 of the Operation Manual)
On the wiper, the ink, dust and paper powder are liable to accumulate. Check the state of the wiper and if it is
stained, clean it.
• Cleaning Liquid Bottle Kit A29 for sublimation dye ink (SPC-0137)
1Move the carriage and open the right
maintenance cover.

(4) Media press (“Cleaning the Media Press” Chapter 4 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 4 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.
Wipe off the sensors with soft cloth or clean sticks.
• For the cleaning of the media sensors, never use the solvent.
• When the sensor is heavily stained, wipe off with a cloth soaked in the waterdiluted neutral
detergent.

3. Periodically care (Once a week)
Users are advised to perform the maintenance works described below once a week so that the printer will
keep its high performance and accuracy over an extended period of its life.
(1) Platen (“Cleaning the Platen” Chapter 4 of the Operation Manual)
Platen is a place where dusts, paper powder, and ink
are liable to accumulate. It is therefore suggested to
clean it frequently. Wipe out the platen surface and the
platen cover with a soft blush or cloth. The grooves for
media holder and for cutting the paper (cutter line) are
the place where the dusts are especially liable to accu-
mulate. Clean them thoroughly.
(2) Exterior (“Cleaning the Exterior Surfaces” Chapter 4, Operation Manual)
Depending on the using environment, the dusts or
sand powder could stick to the exterior of the main
unit. To avoid the entry of the dusts into the moving
part of the head, wipe them off with soft cloth dipped
into water and squeezed tightly.
(3) Waste ink tank (“If a Waste Ink Tank Confirmation Message Appears” Chapter 4 of
the Operation Manual)
Check whether the waste ink tank is full or not. Take care so that the
waste ink never overflows the tank.

7
(4) Ink Discharge Passage (“Washing the Ink Discharge Passage” Chapter 4 of the Oper-
ation Manual)
Wash the ink discharge passage (DISWAY WASH) regularly(about once a week) to prevent the head nozzles
from clogging due to ink coagulation inside the passage.
1Select “MAINTENANCE” menu “STATION” “DISWAY WASH”.
• Refer to the Step 1 to 3 of Chapter 4 “Washing the Ink Discharge Passage” of the user’s manual to
perform the operation.
• The carriage will move onto the platen.
2Open the front cover.
3Press key.
• Dry suction operation is performed repeatedly until the washing work is completed.
4Fill up the cap with cleaning solution for
maintenance.
• Suck maintenance solution into a dropper and fill up
the cap with it. Fill up the cap with maintenance
solution on the verge of overflow from the cap.
5Close the front cover and press the key.
• Before washing the ink discharge passage, make sure that the maintenance washing liquid is set. If
the maintenance washing liquid is not set, washing operation will not be conducted and the passage
could be clogged.

4Clean the O-ring and pinch roller.
• Wipe off the ink sticking to the O-ring and pinci roller with a clean stick dipped in cleaning solution for
maintenance. Wipe off so that cleaning solution for maintenance will not remain.
• Attach a new pinch roller, and reattach a new O-ring to their original position when dirt does not fall even if
it cleans it.
• Be careful not to drop the parts in the gap of the
device as they are small.

11. Safety Precautions
]
12. Installation environment
• Use this printer as much as possible in a dust-free environment. Fans and air-blowers could cause the
dustspewing.
• 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.
CAUTION
Make sure to wear the attached goggles and gloves.
The ink, if mixed with water or alcohol, generates condensed substances. Pay attention not to deposit
water or alcohol to the nozzle surface, surrounding area of the heads, caps and wipers.
To secure the stability of the ink discharge, when the printer is not used (output) for an extended
period of time, it could become necessary to discharge periodically a small amount of ink (flushing),
depending on the kinds of the ink.
When not using for an extended period of time, execute the [CUSTODY WASH] function of this equip-
ment, ("When the Machine Is Not Used for a Long Time (CUSTODY WASH)" Chapter 5 of Operation
Manual) and put off the power switch on the front, only. Leave the main power switch at the side of the
equipment on and keep the cable socket inserted into the plug.
Never disassemble this machine. It could cause electrical shock, fire and breakage.
Keep away the moisture from the inside of this machine. If the inside is moistened, it could cause elec-
trical shock, fire and breakage.
Perform the maintenance and care after switching off the power and taking off the power cable. Other-
wise, it could cause unexpected accidents.
Avoid using benzene, thinner, and chemicals containing abrasive compounds. The surface of the
cover could be degenerated or deformed.
Do not supply lubricant oil etc. to the inside this machine.
It could cause the breakdown of this machine.
