In the modern printing and manufacturing sectors, UV printers are celebrated for their efficiency and precision. However, maintaining optimal performance and extending the lifespan of your UV digital printer requires diligent care. Here is a detailed UV printer maintenance guide covering essential points for when the printer is not in use, during winter, daily operations, and when shutting down, to help you effectively manage maintenance challenges.

 

Maintenance When Not in Use

Short-Term (1-3 Days of Shutdown)

1. Dust Protection: Ensure the printer is protected from dust when not in use by closing the machine's protective cover.

2. Regular Nozzle Cleaning: If the printing material has strong light reflections or significant height differences on the print surface, regularly clean the nozzle surface with a non-woven cloth or cleaning swabs and the appropriate cleaning liquid to prevent the formation of cured dirt.

3. Nozzle Protection: In environments with high dust or strong light, it is advisable to cover the nozzle with a non-woven fabric cover and close the machine’s protective cover.

 

Long-Term (Over 3 Days of Shutdown)

1. Short-Term Shutdown (Up to 7 Days): Perform a purge operation and clean the nozzle. Place it on a clean non-woven fabric.

2. Extended Shutdown (Over 7 Days): Empty the ink and thoroughly clean the nozzle and ink lines with the appropriate cleaning liquid. Ensure all cleaning liquid is removed and the printer is protected from dust.

 

Cleaning Liquid Usage Notes

1. Dedicated Solutions: Use only Hanrun Paper UV ink's dedicated cleaning liquid. Avoid mixing with other brands or solvents.

2. No Substitutes: Cleaning liquid cannot replace moisturizing solutions. Do not drop cleaning liquid into the ink pads or soak the nozzle.

3. Timely Flushing: Do not leave cleaning liquid in the secondary ink cartridges or nozzles for extended periods. Always empty after cleaning.

 

 

Winter Ink Usage Guidelines

1. Environmental Adjustment: In cold and dry winter conditions, keep the printer in an environment with a temperature of 20-35°C and humidity of 45-80% to reduce ink viscosity and static issues.

2. Anti-Static Measures: Connect grounding wires to reduce static and avoid ink spitting issues.

3. Moisturizing Measures: Regularly perform ink tests to ensure the nozzle remains moist. Clean the nozzle if necessary.

 

Ink Storage Conditions

1. Sealed Storage: Store ink in black, sealed containers in a cool, dry place, avoiding direct sunlight and heat sources.

2. Shake Before Use: Shake the ink thoroughly before use.

3. Shelf Life Management: The product shelf life is 1 year. After opening, store the ink in a sealed container and use it within 1-2 months for best results.

2. Ink Replacement: Perform ink replacement in a light-free environment to avoid direct sunlight.

3. Substrate Preparation: Ensure substrate surfaces are clean and dry. Conduct a test print on new substrates.

4. Component Selection: Choose components compatible with UV ink.

5. Environmental Control: Use the printer under suitable temperature and humidity conditions for optimal print results.

6. Regular Cleaning: Clean the nozzle regularly based on usage to avoid dirt accumulation.

 

Personal Protection During Use

1. Avoid Contact: Minimize skin contact with uncured ink.

2. Immediate Action: If ink comes into contact with skin, wipe off immediately with a cloth or paper towel, then wash with soap.

3. Seek Medical Advice: If skin irritation occurs, seek medical attention and refer to the product MSDS for information on the main ingredients.
