Inkjet Printer JV33 Series

Requests for Daily Care and Maintenance

Inkjet printer 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 drawing results could not be obtained. With a view to using this inkjet printer in a better condition, we would like to recommend performing the following care and maintenance on daily basis.

CAUTION

When JV33 printer is used filling solvent ink, make sure to wear the attached goggles and gloves.

The solvent 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 p eriod of time, exe cute the [CUST ODY WASH] function of this equipment, ("In case of no use for long term" P.4-16 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 equipment. It could cause electrical shock, fire and breakage.

Keep away the moisture from the inside of this equipment. If the inside is moistened, it could cause electrical shock, fire and breakage.

Perform the maintenance and care after switching of f the power an d t aking of f 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 equipment. It could cause the break of the printing mechanisms.

1. Installation environment

 Use this printer as much as possible in a dust-free e nvironment. Fans and air-b lowers could cause the dust-

spewing.

 When solvent inks are to be used, install the printer in a well-ventilated space.  The using environment of this printer is from 20 to 35

humidity. Avoid the use of this printer at a temperature and humidity higher or lower than the indicated ranges.

Q Surroundings of the heads ("Cleaning the heads and their surrounding parts" P. 4-16

of the Operation Manual)

The heads and their surroundings are the parts most liable to be tainted in this printer and if tainted, it could cause adverse effects to the functions of the equipment and the results of the drawings. Moreover, as the head itself uses very fine mechanisms, sufficient precautions are required for the care and maintenances.

Q Media press

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 drawings. You are recommended to clean it frequently.

Q Media sensor ("Cleaning the media sensor" P. 4-4 of the Operation Manual)

Two media sensors are provided: one above the platen on the rear surface of the equipment and another on the bottom surface of the head. If the dusts and ink accumulate on the media sensor, it could cause false detection of the media. Wipe off the sensors with soft cloth or cotton rods.

Q Platen ("Cleaning the platen" P. 4-3 of the Operation Manual)

Platen is a place where dusts, paper powder, and ink a re 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.

Q Exterior ("Cleaning exterior surfaces" P. 4-3, 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

Q Waste ink tank ("If Waste ink tank confirming message is displayed" P.4-36 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.

3. Storing of the media

Store the media in the location where the dusts are not liable to accumulate and away from direct su nlight. Avoid storing the media in a place subjected to high temperature and high humidity, as the media abhors humidity, too.

4. Storing of the cartridges

Store the cartridges in a place avoiding di rect s unligh t an d high humidity. As the cartridges are fine and precise articles, avoid dropping or crushing them. Do not make dirty touching or discharge static electricity to the board mounted on the ink cartridges.

5. Examples of defective drawing

Typical examples of the defects created on the drawings by the defective discharge at the head (nozzle) caused by the dusts etc. Check the status of the nozzles periodically before and during the outputting so that the printer is not used under such conditions. The state of the nozzles can be checked by way of “Test drawing” of this printer. ("Head cleaning" P.2-19 of the Operation Manual)

6. Recovery method of defective nozzle discharge

When this printer has not been used for an extended period of time, or depending on the environmental temperature, the discharge at the nozzles could become unstable. In such a case, the following methods may be taken to recover the status of the nozzles.

1. Daily maintenance and care



Perform the cleaning of the parts described in this document.

2. Perform head cleaning (normal). Refer to P2-19 of Operation Manual.



After having performed the care and maintenance stated in step 1, perform the cleaning of the heads in accordance with the procedures stated in Operation Manual.
