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.

When to care
Please take care of it for a short period of time if it is used frequently.

To order replacement consumable items, contact your local dealer or our service office.

• This printer uses a ultraviolet curable ink (UV ink).
• Be sure to wear the included safety glasses and gloves.

Safety Precautions

CAUTION

This printer uses a ultraviolet curable ink (UV ink). Be sure to wear the included safety glasses and gloves.

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 equipment, (“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.

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 benzine, 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.

Aggregates will occur when the UV curing ink(UV ink) is mixed with water or alcohol. Please be careful not to adhere water or alcohol to not only the nozzle surface, but also the head and around the cap, wiper etc.

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.

Notes for working environment

Performing frequency of the print setting or maintenance is greatly influenced by the printing environment or the condition of the media used. Use this machine with a full understanding of the followings.

can expose the nozzle when there is a lot of scattered mist. Raise the refreshing level for drawing (Operation Manual Chapter 3 “Setting of REFRESH”), and set the automatic maintenance ( Operation Manual Chapter 4 “Automatic Maintenance”).§ Increase performing frequency of every maintenance.
When the media that reflects UV light well is used such as glasses or glazed metal
When there is an infrequentlyused ink (print head)| § An infrequently-used print head can be unstable to discharge ink comparing with the other print heads. Raise the refreshing level for drawing (Operation Manual Chapter 3 “Setting of REFRESH”) to raise the usage rate of the head.
When printing on the media on which static can be charged| § Please take a sufficient antistatic such as using the optional ionizer or putting a humidifier. Static may collect mist or dust around the printing area or the head. To print continuously for a long time, set the automatic maintenance. (Operation Manual Chapter 4 “Automatic Maintenance”)
When printing in a dry place (such as in winter)
When printing on a markedly uneven media (or object)| § To keep the head gap the same, please fill the gap by setting media which do not use where a printing media is set. Leaving the head that has been degraded by reflected light may cause failure that needs replacing of the head.

Storage of media

Media should be stored in the little dust area, and not in direct sunlight. Avoid storing the media in the area with high temperature and high humidity.

Storage of ink bottle

Be careful of the followings to store.

• Store the ink bottle in no direct sunlight, and no high humidity.
• As it’s a delicate product, do not drop it.
• Ink IC should not be contaminated and discharged static electricity.
• Be sure to store the ink bottle and the ink IC together.
  

Maintenance when needed

A proper maintenance schedule is determined by the operator who observes throughout a period of use of the printer.

• Some media need maintenance every time of printing.
• The maintenance schedule differs depending on the image to be printed. For example, when the image is almost filled, perform maintenance frequently

Cleaning of head nozzle surface with maintenance liquid 11

Remove ink adhered by stray light around the head.

• Depending on the shape and material of the printed work, prints around the head may be stained, which may cause problems with the printing results. Increase the maintenance frequency according to the staining level

Cleaning of the bottom of the carriage
Remove ink attached to the bottom of the carriage.

Cleaning of the LED UV unit
Remove ink or dust attached to the LED UV periodically

• Clean the LED UV with care in order not to scratch an irradiation part on the bottom of the unit. If there is a certain amount of dirt or a light shielding object on the irradiation part, ink may not cure well and it may cause banding.
• Please replace the part if the stain is too strong.

Removal of ink attached to the table
If necessary, remove ink attached to the table with an alcohol-impregnated cloth. Be careful not to scratch the table face when removing cured ink.

Caution when using solvent

• Leaving the table after attachment of ink may make the ink removal hard with alcohol only. When using a special solvent, contact our office before use. It may cause a failure of the machine.

Removal of the vacuum hole clogging on the table
The vacuum holes on the table can be clogged with ink. Remove the ink in the vacuum holes when needed. Be careful not to leave a part of cured ink on the table.

Daily care

• When possible, use the UJ Cleaning swab 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
