What is the warranty and after-sales service of Hongchuan ?

We offer four types of passes for you to choose from. You can select 2-pass, 4-pass, 6-pass, or 8-pass according to your required printing accuracy. A Pass means one print head scanning stroke over the media. The corresponding printing speed can be adjusted directly in our supporting software. 

2-pass: Highest speed, suitable for mass production with general printing quality

4-pass: Balanced speed and print quality, the most commonly used setting

6-pass: Higher print definition, ideal for fine graphics and small text

8-pass: Maximum printing accuracy, ideal for high-end, delicate artwork

All modes support one-click switching within our printing software. You can tailor the settings to various materials, including rigid boards and roll media with different coatings. The appropriate print mode should be selected based on the specific application rather than speed alone. Factors such as material type, artwork complexity, required resolution, and production volume should all be considered.

Hongchuan offers comprehensive one-stop UV printing equipment solutions with stable and reliable performance for clients across all industries. When selecting a printer, consider your production process and operational objectives. The company provides flexible customization to meet diverse needs including personalized production launches, in-house brand development, and non-standard mass production. Key customization options include: chassis logo customization (engraving client logos on equipment and touchscreen interfaces); customized machine dimensions (tailored to factory space and non-standard printing formats); customized fixtures and jigs (for irregularly shaped workpieces and special materials); and customized printhead configurations. A full range of mainstream printheads available on the market, allowing configuration according to specific needs.

Hongchuan specializes in Ricoh, Toshiba, vision-guided, and compact industrial UV printers, serving industries including electronics, toys, hardware, gifts, advertising, and building materials, with products sold in over 30 countries worldwide.

Hongchuan provides industrial UV printers and digital printing equipment with relevant compliance documentation and quality inspection procedures for international customers.

Applicable models meet relevant CE certification requirements, demonstrating conformity with applicable European Union health, safety, and environmental protection requirements. RoHS compliance confirms that applicable equipment follows restrictions on certain hazardous substances used in electrical and electronic products.

In addition to certification, each machine undergoes systematic quality inspection before shipment. The process includes mechanical assembly checks, electrical debugging, software testing, printing tests, and final outgoing inspection.

These procedures are designed to verify machine assembly, software and electrical functions, and overall printing performance before delivery. For customers with specific market, import, or project requirements, Hongchuan can provide applicable certification and compliance information for the selected machine model before order confirmation.

Hongchuan uses professional export packaging to protect its UV printers and digital printing equipment during international transportation. Each machine is first protected with inner vacuum anti-rust packaging to help reduce the risk of moisture, dust, and corrosion during long-distance shipping.

The machine is then secured in a fumigation-free plywood export case that is suitable for international shipment and customs requirements. The print carriage is mechanically locked before shipment to reduce movement and potential damage during handling and transportation.

Inks, accessories, and other separately supplied items are packed independently to reduce the risk of leakage, impact, or damage to the main machine.

This multi-layer machine packaging process is designed to provide reliable protection throughout loading, transportation, customs clearance, and final delivery. Specific packaging arrangements can be confirmed with the Hongchuan sales team according to the machine model and shipping destination.

Proper printhead maintenance is essential when an UV printer will be shut down for an extended period. Before the holiday, fully flush the printhead and ink tubes with the recommended UV cleaning fluid to remove residual ink and reduce the risk of nozzle clogging.

Gently clean the printhead surface with a lint-free cloth, seal the nozzles with a suitable moisturizing pad, and protect the print carriage from direct UV light. The waste ink tank should also be emptied before storage. Do not leave residual ink inside the printhead or ink system during a long shutdown.

After the holiday, perform the recommended ink-pressing and cleaning procedures, followed by a nozzle test before restarting production. This helps restore stable UV printing performance and reduces the risk of print quality issues.

For detailed procedures, you can also refer to Hongchuan’s holiday printhead maintenance video and technical guidance.
