Requests for Daily Care and Maintenance
This machine is a precision machine equipped with extremely fine mechanisms. Especially, the nozzle surface 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
• 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.
(1) Surroundings of the heads ("Cleaning the Head and the Area around It" Chapter 4 of
the Operation Manual)
• 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.
1
Move the carriage to the left and open the
left maintenance cover.

• Refer to the Step 1 to 5 of Chapter 4 “Cleaning the
Head and the Area around It” of the user’s manual to
perform the operation.
2
Clean the head and the surrounding area.
• Gelled ink and dust could stick under the slider and the surroundings of the head.
• Scrape them off with clean stick etc. In this case, never rub the nozzle portion of the head.
When you clean , fully be
careful not to touch the
nozzle surface.

• Clean the side of the head and the bottom surface of the slider until it looks as shown in the photo
below.
• When you clean , fully be careful not to touch the nozzle surface.
• When you leave during maintenance (or cleaning), please make sure to complete the cleaning by
pressing
key. Without completing the cleaning, the nozzle part is left uncovered and then
outside light makes the ink cure, which causes nozzle clogging or the like.

Clean the bottom surface of the UV lamp.
• If there is any ink stuck on the rear side of the bottom surface of the UV lamp, apply the cleaning solution
for maintenance to a clean stick and wipe the ink away.
Wipe off so that cleaning solution for maintenance will not remain.

(2) Capping Station ("Cleaning the Wiper and Cap" Chapter 4 of the Operation Manual)
The surrounding area of the cap is also liable to be stained by the dust and ink. It is recommended to clean
the head frequently using the cleaning liquid for maintenance suitable for the ink used to avoid the stains on
the head.
• Washing liquid for maintenance (SPC-0568)

• The coating may peel, but this does not cause any functional problems. It may get stuck to the
carriage, though, so peel and wipe away any coating that is peeling.
(6) 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 nozzles and this could interfere the proper printings. You are recommended to clean it frequently.
6
(7) Media sensor ("Cleaning the Media Sensor" Chapter 4 of the Operation Manual)
The media sensors are located on the platen (for two positions) 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.
• When cleaning the media sensor at the bottom of the head, be cautious of the cutter blade near the
sensor to avoid injuries.

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 accumulate. 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 (“Discarding waste ink” 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.
(4) Cleaning the postcure lamp
Make sure dusts and stains are not attached to the lamp.
When there are stains, wet soft cloths with water and wipe after squeezing the cloths firmly.
• After cleaning the postcure lamp, make sure it is completely dry before starting to use.
If used while it is wet, it can cause the luminance of the lamp to decrease.
(5) Checking and adjusting the negative pressure (“If negative pressure abnormality
occurs” Chapter 4 of the Operation Manual)
By the environment or aging, the pressure controlled in this machine may exceed the control range.
Even if an error does not occur, check for negative pressure once per week, and adjust as necessary.

11. Safety Precautions
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, 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.
Make maintenance after the LED UV has been sufficiently cooled, or burn injury may occur.
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 electrical shock, fire and breakage.
Perform the maintenance and care after switching off the power and taking off the power cable.
Otherwise, 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.
