During extended holidays such as the Spring Festival or National Day, many users encounter the same issue:
What to do when 6090 UV flatbed printers are left idle for days or even weeks, leading to nozzle clogging?
Improper maintenance can result in time-consuming cleaning at best or outright nozzle damage at worst, increasing operational costs.
Today, using senior printer 6090 UV flatbed printer as an example, we shall detail a convenient and effective holiday maintenance method to prevent nozzle clogging.
Why is it essential to maintain 6090 flatbed UV printer nozzles during the Spring Festival holiday?
UV inks are fast-drying formulations. During prolonged downtime:
- Ink on nozzle surfaces readily dries and hardens
- White ink is more prone to settling and clogging
- Post-holiday startup often results in broken lines and colour deficiencies
Therefore, pre-holiday nozzle maintenance is more critical than post-holiday cleaning.

Preparations for Spring Festival Holiday Maintenance of UV flatbed printer 6090 Printheads
Prior to commencing operations, please ensure the following materials are prepared:
Foam padding
Stretch film
Lint-free cloth
Syringe
Yellow ink (or light-coloured ink)
Complete Maintenance Procedure for uv 6090 flatbed printer Printheads During Holidays
Step One: Preparing Foam Pads and Lint-Free Cloths
Wrap the foam pad with stretch film for 4–5 turns
Lay the lint-free cloth evenly over the foam pad
Ensure the cloth is smooth and wrinkle-free
Step 2: White Ink Nozzle Bleeding and Replacement Maintenance
First, close the valve of the secondary white ink cartridge
Inject air into the white ink nozzle using a syringe
Completely drain all white ink from the nozzle
Then inject yellow ink (or light-coloured ink) into the white ink nozzle
Until ink beads form on the nozzle surface
This effectively prevents white ink sedimentation and clogging.
Step Three: Colour Ink Pressurisation and Ink Path Closure
Perform ink pressurization on the color inks.
Again, ensure ink beads form on the nozzle surface.
Close the color secondary ink cartridge valve.
Shut down the UV 6090 flatbed printer normally.
Step Four: Moving the Carriage and Moistening the Lint-Free Cloth
Manually move the printhead to the foam pad location.
Pour yellow ink onto the lint-free cloth.
Ensure the cloth is thoroughly saturated.
⚠️ Critical Note:
The cloth must be moistened with ink; never use a dry cloth.
Step Five: Correct Method for Pressing the Printhead onto the Foam Pad (Crucial)
Manually lower the carriage.
Allow the printhead to lightly press against the foam pad and lint-free cloth.
Maintain:
- Contact
- Slight pressure
- Avoid pressing too tightly or leaving gaps
This completes the holiday printhead protection procedure.
Key Precautions for Nozzle Maintenance (Extremely Important)
Do not leave nozzles suspended in mid-air
Do not apply pressure to nozzles when dry
Do not use alcohol or unidentified liquids
White ink must be replaced with light-coloured ink
Secondary ink cartridge valves must be closed before shutdown
What are the advantages of this nozzle maintenance method?
Implementing this approach for Spring Festival holiday maintenance:
- Simple operation, achievable even by novices
- Effectively prevents white ink sedimentation
- Facilitates smoother ink flow upon resumption after the holiday
- Significantly reduces the risk of nozzle clogging
- Extends the service life of the nozzles
