Frequently Asked Questions (FAQ)
Digital Printers – UV / Eco-Solvent / DTF
By our Technical Support Engineer Team
General Questions
Q1: What are the main differences between UV, eco-solvent, and DTF printers?
A:
- UV Printers use ultraviolet light to instantly cure the ink on surfaces like acrylic, metal, glass, wood, plastic, and more. Ideal for signage, customized items, industrial printing.
- Eco-Solvent Printers (often referred to as “photo printers” or “solvent plotters”) are typically used for indoor and outdoor banners, posters, vehicle wraps, and vinyl printing. They require coated materials for optimal output.
- DTF Printers (Direct-to-Film) transfer designs onto PET film using special inks and powder, then heat-press onto garments. It's widely used in apparel decoration.
UV Printer FAQ
Q2: What materials can UV printers print on?
A: UV printers can print directly on flat and curved surfaces including PVC, acrylic, glass, wood, metal, leather, tiles, and even cylindrical items with rotary attachments.
Q3: How do I maintain the UV print head?
A:
- Daily clean the capping station and wiper.
- Ensure the nozzle plate remains moist (especially in dry climates).
- Use the printer’s automatic cleaning or manual soft flush to prevent clogging.
- Power off properly using the shutdown sequence to activate the ink-lock system (if equipped).
Q4: How long does UV ink last?
A: Typically 12–18 months if stored properly. After opening, it’s best to consume the ink within 2–3 months. Always shake gently before use.
Eco-Solvent Printer FAQ
Q5: Why does the print appear blurry or misaligned?
A: Possible causes include:
- Media not loaded flat.
- Printhead alignment offset.
- Carriage belt wear or looseness.
- Improper voltage or static buildup on material.
Perform regular calibration and use recommended media types.
Q6: Is ventilation required when using eco-solvent printers?
A: Yes. While eco-solvent ink is less volatile than traditional solvent, good ventilation ensures user safety and optimal curing. Use in a well-ventilated workspace or with fume extraction.
DTF Printer FAQ
Q7: Why is my DTF print not transferring well to fabric?
A: Common causes:
- Film not properly cured (incomplete powder melting).
- Incorrect heat press settings (temperature/time/pressure).
- Low ink density in dark areas.
Ensure oven curing reaches 110–120°C for 2–3 minutes and heat press at 160–170°C for 15s with medium-high pressure.
Q8: What kind of fabric is compatible with DTF printing?
A: DTF can be applied to cotton, polyester, canvas, blends, nylon, and more – both light and dark garments.
Q9: How to prevent ink clogging in DTF printers?
A:
- Use daily automatic cleaning or soft nozzle check.
- Stir the white ink tank periodically to prevent pigment settling.
- Keep the room temperature stable and humidity around 40–60%.
- If not used for more than 2 days, flush the white channel or power flush.
Troubleshooting & Maintenance
Q10: What is the best environment for printer operation?
A:
- Temperature: 20–28°C
- Humidity: 40–60%
- Dust-free, ventilated space
- Stable voltage with surge protection recommended.
Q11: How often should I replace ink dampers or caps?
A:
- Ink dampers: Every 3–6 months depending on usage
- Capping station & wiper: Every 6–12 months or sooner if worn
- Always use OEM or high-quality compatible parts.
Q12: Why is my printer printing blank pages?
A:
- Nozzle blockage
- Ink not reaching the head (ink damper empty)
- Air in the ink line
- Electrical disconnection or mainboard issue
Try priming the ink line, cleaning the head, or seeking technician support if the issue persists.
Buying & Support
Q13: Do your printers support multiple languages in the interface?
A: Yes. Most of our systems support English, Spanish, Portuguese, and Chinese interfaces. More can be customized based on request.
Q14: What kind of training or support do you provide?
A:
- Online installation & training guidance via video call
- User manuals and maintenance checklists included
- After-sales team available via WhatsApp, WeChat, Email
- Local service support available in select regions.
Q15: How long is the warranty period?
A:
- Standard: 1-year warranty for machine body and boards
- Printhead: No warranty (as industry standard), but we provide usage training to prolong life
- Lifetime technical support provided for all customers.
Other Common Questions
Printing process interrupted ink
Check the negative pressure value and adjust it to the appropriate value;
Stop printing and observe the surface of the nozzle. If there is ink, wipe the nozzle with a non-woven fabric after normal ink pressing;
Discharge air from the nozzle, press ink, and wipe the nozzle;
Replace the filter between the secondary ink cartridge and the nozzle.
Ink flying at the edge of homework
There is static electricity on the surface of the medium:
Perform static elimination treatment
Inappropriate nozzle voltage:
Contact technical personnel
New homework printing, color difference too large
ICC is not suitable:
Choose the correct RIP parameters (input ICC, output ICC, pass count, resolution, etc.)
Incorrect printing mode:
Check printing parameters (speed, one-way and two-way, pass count, lighting mode, white ink parameters, etc.)
