Self-Service Phone Case Printing Vending Machine Maintenance Guide
Thank you for choosing our DIY phone case printing vending machine! This smart device combines the latest technology with easy-to-use services. Regular maintenance improves the user experience, makes the device last longer and reduces the risk of it breaking. To help our users in other countries look after their equipment, we've created a full guide to maintenance. This includes how to use the equipment every day, how to clean it, and how to solve common problems.

1. Daily Maintenance and Basic Checks
1.1 Exterior Cleaning
Wipe the outside of the machine, the touchscreen and the control panel every day with a soft, dry cloth. This will stop dust or liquid from affecting how well it works.
If you put the machine outside or in a place where there is a lot of dust, you should clean it every week using a diluted, neutral detergent (don't spray it directly on the machine).
1.2 Printing Module Maintenance
Inkjet/UV Printhead Cleaning:
Before you turn it on, check the nozzle using the built-in menu to make sure the patterns are clear and there are no interruptions.
If you see streaks or blurriness, immediately use the system's "printhead cleaning" function.
Please note: If the machine hasn't been used for a long time, clean the printhead every week. Wear gloves and gently wipe it with a lint-free cloth that has been moistened with a special cleaning solution.
Consumable Monitoring:
Check the levels of both types of ink regularly to avoid printing problems caused by running out of ink.
The device has a low-ink warning system. Please replace the cartridges with the original manufacturer's cartridges as soon as possible (non-original inks may block the printhead).
1.3 Mechanical Component Inspection
Conveyor Belt and Guide Rails:
Monthly, inspect the conveyor belt for looseness or misalignment.
Clean debris from the rails with a soft brush and apply a small amount of silicone grease for lubrication.
Phone Case Slots:
Ensure slots are free from deformation or adhesive residues to prevent jamming when users insert phone cases.
2. Periodic Deep Maintenance (Recommended Every 3 Months)
2.1 Internal Dust Removal
Turn off the power and unplug the device. Then open the back cover (use the right tools).
Use compressed air or a small vacuum cleaner to remove dust from circuit boards, fans, and mechanical parts.
Important: Do not touch the precision sensors or circuit interfaces when you are cleaning them.
2.2 System and Software Updates
Connect the device via Wi-Fi or USB to regularly update firmware and design template libraries, fixing bugs and enhancing compatibility.
Reset operation logs by deleting outdated order records to free up storage space.
2.3 Payment System Inspection
Test the coin acceptor, bill validator, and QR code payment modules to ensure smooth transactions.
Clean the QR code scanner and coin slot sensors with a cotton swab dipped in a small amount of alcohol.
3. Environmental and Usage Considerations
3.1 Placement Requirements
Avoid direct sunlight or humid environments (ideal temperature: 15–30°C, humidity: 30–70%).
Ensure the machine is placed on a stable surface, away from vibration sources (install anti-vibration pads in high-traffic areas).
3.2 Consumable Storage
Store unused blank phone cases in a dry, dark place to prevent moisture deformation.
Seal ink/UV ink in a cool environment; it's recommended to use them within 6 months after opening.
4. Common Troubleshooting Guide
| Issue | Possible Cause | Solution |
|---|---|---|
| Touchscreen unresponsive | Static interference or screen dirt | Restart the device; clean the screen with alcohol wipes |
| Misaligned/blurred printed images | Printhead misalignment or low ink | Perform "print calibration"; check ink levels |
| No response after successful payment | Disconnected communication module or system lag | Restart the device; check network connection |
| Phone case stuck in conveyor belt | Obstruction or misaligned guide rails | Power off and manually remove; check rail alignment |
