Warranty, sample testing, production lead time and overseas service

Standard warranty

• Warranty starts on the date the buyer receives the machine.
• Standard term: one year.
• Printheads are excluded from the standard warranty.
• UV lamps, filters and ink-system consumable parts are covered when the failure meets the written warranty conditions.
• Damage caused by collision, incorrect operation, non-approved ink or voltage problems is excluded.

Sample testing

• There is no sample-printing service charge.
• No universal quantity, size or frequency limit is currently set, subject to equipment, shipping and safety feasibility.
• The buyer pays shipping to SUNUSER and return shipping.
• Use the real substrate and artwork, with an agreed acceptance method.

Production and transport

• Normal production planning is about 30–40 calendar days.
• The period starts when the deposit is received and includes Chinese statutory holidays.
• Domestic or international transport time is additional.
• The contract controls the actual date for each configuration and custom project.

Overseas on-site service

• Overseas work requires prior written confirmation of personnel, scope and schedule.
• Engineer service is RMB 1,000 per person per day, counted from departure through the return day.
• The buyer pays round-trip airfare, visas, accommodation, meals and local transport.
• Final headcount, days and costs require written confirmation.

Post-warranty remote support

• After warranty, remote operational guidance and routine diagnosis are generally not charged when the customer continues to use SUNUSER ink.
• Parts, engineer travel, on-site work and separately scoped complex services may be quoted.
• Remote guidance is not an unconditional lifetime-free-repair promise.
