How To Maintain A UV Vertical Wall Printer?
Table of Contents
When customers consider investing in a UV wall printer, one of the most common questions is: “Is maintenance complicated?” The answer is simple — no.
Maintenance mainly focuses on the printhead, and with Friankor’s wall printers, the process is easy to manage. Regular use, a clean environment, and basic care are all you need to keep your wall printing machine running smoothly for years.
Professional Printhead Protection with Friankor
Before we talk about daily care, here’s why Friankor users enjoy peace of mind:
- Official Epson partnership – Every DX7, I1600, or I3200 printhead comes directly from Epson, with 100% authenticity guaranteed.
- Stable mechanical structure – Friankor designs and manufactures wall printers exclusively for vertical applications. The rigid frame and servo-driven motion keep the printhead stable during every job.
- Calibrated color and waveform system – Each printer is tuned by our engineers to match the ink’s waveform and curve, ensuring vivid color, consistent saturation, and fewer cleaning cycles.
✅ 1. Daily Maintenance
1. Avoid Long Idle Periods
If the printer is not used for more than a week, power it on once per week and run a nozzle check to keep ink flowing smoothly.
If you cannot power it on regularly, place a protective sponge pad with maintenance liquid inside the printhead capping area (included with Friankor machines). This keeps the head moist and prevents ink from drying and blocking the nozzles.
2. Maintain Proper Environment
Avoid using or storing the printer in dusty areas or under direct sunlight for long periods.
UV light accelerates ink curing, so when working outdoors, use shade or cover to protect the printhead and ink system from exposure.
3. Use Original Ink
Always use original UV ink. Non-original ink may cause nozzle blockage, corrosion, or shortened printhead life.
Different ink brands have different compositions and parameters (such as waveform and color curve).
Do not mix inks — it can lead to chemical precipitation and clogs. When changing ink brands, make sure to flush the system completely before refilling.
4. Clean the UV Wall Printer Regularly
Clean both the interior and exterior of the machine regularly, especially around the printhead area, to prevent dust accumulation that could affect print quality.
✅ 2. Troubleshooting Common Issues
If you see broken lines or missing segments during test printing:
- Inspect the nozzle test pattern.
- Perform manual ink suction using Friankor’s suction tool.
- Ensure the suction pad is aligned correctly with the printhead, with no tilting.
- Pull ink in one direction only — do not push ink back, to avoid air bubbles or nozzle damage.
Friankor provides a dedicated suction tool and detailed tutorial to guide you through the process.
If the problem persists, contact Friankor technical support promptly to avoid further damage.
✅ 3. Long-Term Storage and Deep Maintenance
i: When Idle for More Than One Month
Apply original Epson protection liquid on the capping pad to effectively isolate the printhead from air and prevent ink drying.
ii: Disassembly and Cleaning (Professional Service Recommended)
If the printhead must be removed for cleaning, it should only be done by trained personnel.
After cleaning, apply protection liquid on the nozzle surface and seal the printhead in a cool, dry place.
iii: Important Notes
Be cautious with cleaning liquids: non-approved cleaners may corrode internal components and cause permanent damage.
Follow the manual: always read and follow the maintenance instructions in your Friankor user manual before performing any procedure.
How Often Should You Print?
- Every 2–3 days: ideal for keeping ink active.
- Once a week: minimum recommended usage (nozzle check + test print).
- Over 1 week idle: keep the printhead wet-capped with the protective pad.
- Over 1 month idle: flush ink, add protection liquid, and store properly.
