User Guide: Locor A3 UV DTF Printer (XP600 Dual/Triple Head)

The Locor A3 UV DTF Printer is a specialized, industrial-grade solution designed for continuous, high-efficiency roll-to-roll cold sticker and label production. Equipped with an integrated inline lamination system and multi-printhead technology, it lets you create vibrant, scratch-resistant 3D textured gloss transfers for curved, round, or irregular surfaces that cannot fit into a traditional flatbed printer.

1. Critical Pre-Setup & Environment

• Workstation Footprint: Ensure your table can accommodate the machine size of 1180 × 750 × 650 mm and its 80 kg operating weight. The machine must be placed on a completely level, vibration-free surface to maintain alignment across the film rolls.

• Atmosphere Control: To keep the heavy-pigmented white ink flowing and protect the fine nozzles of your Epson XP600 printheads from premature curing:

  • Temperature: 20°C – 35°C (Stable).
  • Humidity: 35% – 70% RH.

• Power Supply: Operating on a standard 220V connection, the machine’s electronic mainboards are highly sensitive to power grid fluctuations. To safeguard your investment from voltage spikes and protect your warranty, it is highly recommended to connect the printer to a 5KW Voltage Regulator or an online industrial UPS.

2. Advanced Ink System Management

This printer balances a large-volume ink supply with automatic systems to ensure uninterrupted multi-color printing.

• Large Capacity Tanks: Features high-volume 500ml per color ink tanks, dramatically reducing the frequency of refills during long production runs.

• Multi-Channel Configuration: Configured for CMYK + White + Varnish. The white ink acts as a solid background layer on clear film, while the varnish channel builds premium, tactile 3D embossed gloss effects.

• White Ink Care: Because white UV ink contains heavy solids that quickly settle, the machine features an automated circulation system. Always keep the printer powered on so the system can continuously agitate the ink and protect the white printhead from blocking.

3. Operating Instructions

Step 1: Media Loading & Alignment

• Film A (Printing Film): Load the primary printing film roll onto the rear feeding shaft. Thread it flat through the printing bed, ensuring it stays perfectly square and unwrinkled.

• Film B (Lamination Film): Set the B-film transfer roll onto the upper lamination bracket. Pull the leading edge down and align it with the lamination rollers.

Step 2: Sending the Print Job

Using your RIP software on Windows 7 or Windows 10, import your files (TIFF/PNG with spot color channels):

• Mirror Settings: Ensure “Mirror Image” is checked in your RIP workflow before printing, as the graphic will be transferred face-down onto the final substrate.

• Layer Configuration: The printer executes a single-pass workflow: it prints the CMYK graphics layer, instantly coats it with the White backing ink, applies the Varnish layer, cures it instantly with the built-in LED lamps, and passes it straight into the cold laminating rollers.

4. Maintenance Best Practices

• The Daily Nozzle Test: Every morning before beginning production, run a manual nozzle check strip. With 2 or 3 XP600 printheads splitting the labor, verify that all lines across your CMYK, White, and Varnish channels are firing crisp and 100% complete.

• Automatic Head Cleaning: The machine features an integrated Automatic Cleaning System to clear the nozzle plate. However, manually wiping away rogue ink accumulation on the capping station and wiper blade daily using lint-free swabs and UV cleaning fluid is highly recommended.

• Capping Station Seals: Inspect the rubber cap tops regularly. A perfect airtight seal when the machine parks is critical to prevent the UV ink from drying out and crusting on the head surface overnight.

5. Material Transfer & Application Guide

Once your roll of UV DTF stickers is printed and laminated, applying them to materials requires no extra machinery—just peel and stick!

💡 Sourceprinting Pro-Tip:

Consumables like the printhead, dampers, cables, and cap tops are exposed to constant chemical contact and are excluded from the standard 1-Year Warranty. To maximize the life of your XP600 heads, never let the machine sit idle without printing for more than two days. If you are taking a short holiday, perform a thorough manual head flush and secure a “Wet Cap” with moisturizing fluid to keep the nozzle plate from solidifying.
