Huafu After-Sales Policy

If a product issue occurs, Huafu will first work with the customer to identify the cause and provide an appropriate solution. Depending on the issue, support may include:

• Remote diagnosis and operating guidance;
• Software troubleshooting;
• Replacement of defective parts;
• Equipment repair;
• On-site technician service when necessary;
• Replacement, return, or refund if the issue cannot reasonably be resolved.

A product malfunction does not automatically qualify the product for return. Customers are expected to reasonably cooperate with Huafu's technical team during troubleshooting.

Incomplete information may delay service. Customers may be asked to provide:

• Order or invoice number;
• Product model and machine serial number;
• Description of the issue;
• Photos, videos, error messages, or screenshots;
• Information about inks, materials, consumables, installation, or operating conditions;
• Other information reasonably required by Huafu Technical Support.

Incomplete information may delay service.

Huafu will normally try to resolve issues remotely before arranging an on-site technician.

If on-site service is required, labor, parts, transportation, accommodation, and other reasonable travel expenses will depend on the cause of the issue, warranty status, and applicable order terms.

For confirmed product quality issues within the warranty period, Huafu may provide free or reduced technician labor depending on the order. For customer-caused issues or products outside the warranty period, the customer may be responsible for service, parts, and travel costs.

Any applicable charges will be confirmed before the technician visit is arranged.

Customers should contact Huafu Customer Service before taking further action.

DO NOT ship any machine or product back until Huafu provides instructions.

During the applicable warranty period, if Huafu confirms that an issue is caused by manufacturing, assembly, or an inherent product defect, Huafu may provide:

• Remote technical support;
• Fault diagnosis;
• Software troubleshooting;
• Replacement of covered parts;
• Repair;
• Machine replacement;
• Another reasonable service solution.

Warranty periods may vary by product and will be based on the applicable order, quotation, contract, or warranty documentation.

Warranty service generally does not cover damage or malfunction caused by:

• Improper installation, operation, or maintenance;
• Incompatible ink, consumables, software, parts, or accessories;
• Incorrect voltage, unstable power supply, or incorrect wiring;
• Failure to perform required cleaning or maintenance;
• Unauthorized disassembly, modification, repair, or parts replacement;
• Collision, water damage, misuse, or other external damage;
• Normal wear and tear;
• Use outside the product's recommended operating conditions;
• Other issues confirmed to be unrelated to product manufacturing quality.

Huafu may still provide repair or technical support for these situations, but parts, labor, and related costs may be charged to the customer.

A product may be considered for repair, replacement, exchange, or return when:

• A confirmed manufacturing defect affects normal use;
• The product does not match the confirmed order;
• The issue cannot be resolved after reasonable troubleshooting;
• The product was seriously damaged during shipping;
• Major parts or accessories are missing upon delivery.

Final eligibility will be determined after Huafu's technical and after-sales review.

A replacement machine does not automatically mean that the original machine has been formally returned or refunded. If Huafu provides a replacement machine first, the original machine must be returned as instructed.

After inspection, Huafu may classify the case as a repair, replacement, customer-caused damage, product quality issue, or formal return.

Unless otherwise agreed in writing:

• Machines and equipment: Return or exchange requests should generally be submitted within 30 days after delivery.
• Missing parts or visible shipping damage: Should generally be reported within 7 days after delivery.
• Accessories and unopened consumables: Return requests should generally be submitted within 7 days after delivery, and the product must remain unused, uninstalled, and properly packaged.

The 30-day period does not mean that machines qualify for unconditional returns.

Returns unrelated to a product quality issue may be accepted or rejected by Huafu based on the circumstances.

The end of the return period does not end the applicable product warranty.

Customers must receive approval from Huafu before returning any product. Return shipping should only be arranged after Huafu provides authorization and return instructions.

Unauthorized returns may be refused, and any resulting shipping, storage, or reshipping costs may be the customer's responsibility.

Returned machines must be properly packaged to prevent shipping damage.

Customers should keep the original packaging, protective materials, crates, pallets, and accessory packaging whenever possible. Wooden crates, pallets, or special packaging are not automatically included with every machine and will depend on the applicable order or shipping arrangement.

If original packaging has been lost or damaged, the customer may be responsible for reasonable repackaging costs. The customer may also be responsible for damage caused by inadequate return packaging.

If the return or exchange is caused by a confirmed Huafu responsibility, such as:

• Manufacturing defect;
• Incorrect model shipped;
• Incorrect product shipped;
• Other confirmed shipping errors;

reasonable return shipping costs approved in advance may be covered or reimbursed by Huafu. If the return results from customer-related reasons, including:

• Incorrect order;
• Change of mind;
• No confirmed product quality issue;
• Improper operation;
• Selection of an unsuitable product;
• Failure to confirm compatibility;

return shipping, reshipping, and related costs will generally be the customer's responsibility. Shipping arrangements for large machines must be confirmed with Huafu before shipment.

Approved refunds will generally be based on the actual amount paid for the applicable order, not the current market price. Depending on the reason for the return and the condition of the product, reasonable deductions may include:

• Non-refundable shipping costs;
• Customer-caused product damage;
• Missing accessories;
• Repackaging;
• Cleaning, restoration, or refurbishment;
• Loss in value caused by the customer;
• Agreed customization or special handling costs.

The final refund amount will be determined after product inspection and financial review.

Printheads are precision components and have different return and warranty rules from standard machines and parts. Huafu may record the printhead model, identification number, or serial number before shipment.

A printhead will generally not qualify for return as an unused part once it has been:

• Installed;
• Powered on;
• Filled with ink;
• Cleaned, flushed, or tested;
• Damaged by improper installation, voltage, ink, cleaning, or similar causes.

If a printhead is believed to have an original quality defect, stop using it and contact Huafu immediately. Huafu will review the printhead identification, use history, inspection results, and applicable supplier or manufacturer warranty terms before determining the appropriate solution.

Ink, film, roll media, powder, cleaning fluid, and other consumables are generally not returnable for customer-related reasons once opened or used.

Customers should confirm product specifications, compatibility, and quantity before purchase.

If a consumable is believed to have a quality issue, stop using it and contact Huafu with the batch number, packaging information, photos, videos, or other requested evidence. If a product quality issue is confirmed, Huafu may provide replacement, reshipment, or another reasonable solution.

Custom or special-order products may include:

• Special machine sizes;
• Special configurations;
• Special voltage requirements;
• Specific printhead or component configurations;
• OEM products or customer logos;
• Parts purchased specifically for a customer;
• Products already in production or modification based on customer requirements.

Once purchasing, production, modification, or customization has begun, Huafu may decline cancellations or returns requested for customer-related reasons.

If Huafu agrees to a cancellation, the customer may be responsible for reasonable non-recoverable production, material, processing, or customization costs.

Demo machines, display units, warehouse-stock machines, and other special-condition machines may have different cosmetic, packaging, warranty, or return conditions from standard new products.

The product condition and any special terms should be confirmed in writing at the time of sale.

To the extent permitted by law, Huafu will not be responsible for delays, losses, or additional costs caused by circumstances beyond its reasonable control, including:

• Customs delays;
• Carrier or transportation delays;
• Natural disasters;
• War or conflict;
• Strikes;
• Government restrictions;
• Import or export restrictions;
• Other events beyond Huafu's reasonable control.

This policy should be read together with the applicable quotation, order, invoice, sales contract, product documentation, and warranty documentation.

If separate written terms have been agreed for a specific order, those terms will apply to that order to the extent permitted by law.

Huafu may reasonably update this policy based on product types, supplier warranty requirements, and business needs.
