1. Daily Maintenance

The JFX200-2513EX, JFX200-1213EX is a precision machine with extremely fine mechanisms. The nozzle surface of the head can be affected by dust or paper powder, leading to poor print results. Performing daily maintenance is recommended for optimal conditions.

Maintenance Timing

Tools Necessary for Maintenance

• F-200/LF-200 maintenance liquid (PN: SPC-0568)
• PR-200 maintenance liquid (PN: C-ML013-Z-B2-1-KW) *When using the PR-200 ink
• Cotton swab
• Cleaning Stick for Head Surrounding (PN: SPC-0527)
• Soft cloth
• Gloves

Precautions for Maintenance

• [!] The LED UV unit becomes very hot. Turn off the LED UV unit and perform maintenance once the device cools down sufficiently. There is a risk of burns.
• [!] Switch off the power button and unplug the power cable before cleaning. It may cause unexpected accidents.
• [!] If you will not be using the machine for a long time, make sure you remove the power cable from the outlet and remove the media that is set in the machine.
• [!] When handling ink and washing liquid, pay close attention to ventilation and be sure to wear the included safety glasses and gloves. The ink or washing liquid may get in your eyes.
• [!] Do not use chemicals containing benzine, thinner or abrasives. It may cause degeneration/deformation of cover surface.
• [!] Do not lubricate the inside of the device with lubricating oil or other agents. Doing so may cause malfunction.
• [!] Make sure the washing liquid and ink do not get on the cover. This may cause degeneration/deformation of the cover surface.
• [!] Aggregates are generated in the UV ink (ultraviolet curable ink) if it is mixed with water and alcohol. Do not let water or alcohol stick on the nozzle surface, cap, wiper, or anywhere near the head.
• [!] Never disassemble or modify this machine or ink bottle. Disassembling or modifying will result either in electric shock or malfunction of this machine.
• [!] Do not let moisture enter this machine. If the inside of the machine gets wet, it may cause electric shock and damage.

Installation Environment

• Do not use in a dusty place. It may lead to problems in the printer or poor printing.
• For stable printing, use this machine in an environment with a temperature in the range of +15 °C to +30 °C (59°F to 86°F) and Rh in the range of 35 to 65%.

Notes Regarding Work Environment, etc.

The frequency of configuring print settings and conducting maintenance is largely influenced by the work environment and media conditions. Understand the following items before use:

• If there is a lot of dust or dirt in the work environment:
  
  • To keep the nozzle surface clean, perform interval wiping after about every 1500 mm of printing. (Refer to Operation Manual, Chapter 3: "Setting Nozzle Face Cleaning Frequency")
  • Change interval wiping settings according to the amount of dust or dirt.
• When the head gap value is set to large due to reasons such as fibers protruding from the media
• When media that can easily reflect UV light, such as glass or glossy metal is used:
  
  • UV light may get exposed onto the nozzle due to frequent mist scattering. Increase the REFRESH level during plotting, then set interval wiping. (Refer to Operation Manual, Chapter 3: "Other Settings" and "Setting Nozzle Face Cleaning Frequency")
  • Increase the frequency of all types of maintenance.

In Case of Low Ink Usage (Print Head)

• Ink discharge of less used print heads tends to become unstable. Increase the REFRESH level during plotting and keep the head usage rate above a certain value. (Refer to Operation Manual, Chapter 3: "Other Settings")

When Printing on Media Prone to Electrostatic Charge

When Printing in an Environment with Low Humidity (e.g., Winters)

• Take measures against electrostatic charging with a humidifier. Static electricity attracts mist and dust around the printing area and the head. Set interval wiping if printing is to be continued for a long time. (Refer to Operation Manual, Chapter 3: "Setting Nozzle Face Cleaning Frequency")

When Printing on Uneven Media (Three-Dimensional Medium)

• To keep the head gap as constant as possible, set unnecessary media, etc., even at locations other than the suction area. If head deterioration due to reflected light is neglected, it may cause malfunction requiring head replacement.

Storing Media

Store media in a dust-proof place with no direct sunlight. Avoid storing in hot or highly humid places.

Storage of Ink Bottles

• Store in a place with low humidity and no direct sunlight.
• Do not drop or smash the ink bottle.
• Avoid contamination or electrostatic discharge of the Ink IC chip.
• Always store the ink bottle and Ink IC chip together.

Examples of Plotting Failure

Discharge failure of the head (head nozzle) due to dust is a typical example of plotting failure. Periodically check the condition of the nozzle before or during output to avoid using it in a defective state. The condition of the nozzle can be checked by [TEST PRINT].

2. Daily Maintenance

Maintenance of Head Surroundings

• When cleaning the area around the head/capping station/wiper, use a Cleaning Stick for Head Surrounding (PN: SPC-0527). Using a normal cotton swab may leave lint threads, causing secondary failures.
• Perform maintenance for the ink cap and wiper in the capping station daily. If left dirty, the nozzle surface may get dirty, and dust or hardened ink may stick to the nozzle, resulting in poor discharge.
• Clean the bottom surface of the carriage daily to prevent ink or dust accumulation. If left dirty, dirt or hardened ink may smear onto the nozzle due to wiper operation during head cleaning.
• When cleaning the bottom surface of the carriage, be careful not to rub the nozzle.

Extremely minute mechanisms are used for the head, requiring proper care during maintenance. Gel-like ink or dust may accumulate in the bottom part of the slider and around the head. Rub it off using a clean stick or similar tool. Never rub the nozzle part of the head.

Tools required for cleaning: Cleaning Stick for Head Surrounding (PN: SPC-0527), Safety glasses, Gloves.

• [!] If ink gets on skin or clothes, rinse immediately with soap or water. If ink gets in eyes, wash immediately with water and consult a doctor.

About Refilling the Cooling Water

To cool the LED UV unit, put antifreeze liquid mixed with water into the cooling water tank. The water and antifreeze liquid (PN: SPC-0394) ratio should be 2 (water) to 1 (antifreeze).

Illustration: Shows the cooling device.

Notes on Refilling

• [!] The water and antifreeze solution ratio should be 2 (water) to 1 (antifreeze).
• [!] If only water is put in the cooling water tank without antifreeze liquid, the LED UV unit may malfunction due to freezing.
• [!] If only antifreeze liquid is supplied without water, the machine will not work properly and errors may occur.
• [!] If you notice frequent water shortage, contact your local distributor or sales office.
• Dispose of wastewater mixed with antifreeze pursuant to regional regulations.

Antifreeze Mixture Precautions

1. Use water that satisfies the following conditions:
   
   • Calcium content: Not exceeding 10 mg/L (1 mg/100 ml)
   • Hardness: Not exceeding 60 mg/L
   • Distilled or purified water
2. Do not use antifreeze mixture prepared far in advance.
3. Any excess antifreeze mixture must be used within one week. Filling with mixture prepared more than one week in advance may lead to malfunction.

Precautions for Handling Antifreeze Liquid

• Always use an antifreeze liquid recommended by Mimaki.
• Do not touch the antifreeze liquid directly. If contact occurs, wash immediately with soap and water. If it gets in eyes, wash immediately with plenty of water and consult a physician.
• Store the antifreeze liquid in a cold and dark place.
• Keep out of reach of children.
• Entrust disposal of unused antifreeze liquid to an industrial waste disposal contractor.
• Be sure to read the Safety Data Sheet (SDS) before using antifreeze liquid.
• When handling antifreeze liquid, wear included safety glasses and gloves.
• Prepare a tank with a cap for moving waste water from the cooling water tank.
• The following error message is displayed when water in the cooling water tank is low: "WATER LACK". Replace the water as shown in "Refilling the Coolant".

Refilling the Coolant

If an error suggesting lack of water occurs, refill the coolant. Approximately 500 cc is required.
