I. Hardware Introduction
1. Triangular Structure
Component List:
Main power box, printhead, motherboard, head board.
X-axis track (2.35 meters), belt, and other items.
Total guide rail length: 4.5 meters (three sections of 1.5 meters each).
Accessories: ink bags, ink cartridges, ink tubes, nozzles, ink, tool kit, etc.
Installation Steps:
Guide Rail Assembly
Align the rack teeth carefully. Avoid any misalignment or jams.
Secure the screws on the mounting plate and check for flatness.
Main Unit Mounting
Align the unit with the sliding track. Ensure the rack teeth match properly.
Fold the unit upward and secure all screws (both top and bottom must be locked).
Power Box Connection
Connect the Y-axis motor power cable, control panel sensor cables, and leakage protection cable.
2. Ground Rail Structure
Component List:
Main unit includes: power box, printhead, X-axis track (2.35 meters), and rack (4.5 meters).
Accessories are the same as for the triangular structure.
Installation Steps:
Guide Rail Assembly
Align the rack interfaces. Check the mounting plate for evenness.
Unit Alignment
Align the sliding track. Once the rack is fixed, secure the moving wheels.
Computer Connection
Use a UPS plug to connect the computer and install the control software.
II. Control Software Operation (UltraPrint & WellPrint)
1. Software Installation
Unzip the compressed file and install the software.
Disable antivirus software during installation to avoid conflicts.
Recommended system: Windows 7 (64-bit, Core processor).
2. Print Settings
Image Processing:
Import a JPG image.
Rotate the image by 90°.
Adjust the size.
Select the appropriate print curve (e.g., HC_Car Wrap Curve).
Output File:
Save the file in PRN format.
Load the print job through WellPrint.
Calibrate the X/Y axis movement values.
3. Calibration and Testing
X/Y Axis Calibration:
Adjust movement values (e.g., X: 800, Y: 500).
Enter the actual distance to calculate the gear ratio.
Flash Test:
Set the flash frequency to 128.
Verify the nozzle status. Eight neatly aligned sprays indicate normal operation.
III. Printing Operation Process
1. Preparation
Measure the distance between the machine and the wall (61 cm for the triangular structure; 24 cm for the ground rail structure).
Adjust the level and ensure a smooth ink flow.
2. Printing Steps
Start the flash test.
Adjust the nozzle distance (should be ≤1 cm).
Import the PRN file.
Set printing parameters.
Begin printing.
Key Parameters:
Nozzle distance.
Ink volume adjustment (reduce by 5% to prevent ink bleeding).
Print resolution (match the print curve, e.g., 720*1200).
IV. Common Troubleshooting
| Issue | Solution |
|---|---|
| Nozzle moves in only one direction | Check the motherboard indicator lights and verify if the limiters are loose or damaged. Refer to the limiter diagram. |
| Ink splatter/bleeding | Adjust the nozzle distance to ≤1 cm. Reduce ink volume by 5%. Apply a primer on the wall. See the ink bleeding illustration. |
| Interrupted ink flow or missing channels | Check the ink supply. Reseat the cable after removing any dried ink (ensure the area is dry). Refer to the cable connector diagram. |
| Incorrect print dimensions | Calibrate the gear ratio (e.g., X-axis 9.76, Y-axis: Triangular 233 / Ground Rail 133). Check the motion settings interface. |
| Pattern overlap or stalling | Ensure the rack is flat. Check that no wires are obstructing the guide rail. |
V. Maintenance and Care
1. Daily Maintenance
Nozzle Care:
Do not use cleaning liquids to wash the nozzles.
If idle for more than 7 days, cover the nozzles with cling film and a moisture-preserving solution.
For long-term storage, remove the nozzles, rinse them, and seal for preservation.
Guide Rail Maintenance:
Regularly clean the guide rails.
Apply sewing machine oil to keep them smooth.
2. Precautions
Environmental Requirements:
Avoid installation during winds above level 5 or rainy conditions.
Keep the area dust-free and rodent-proof.
Operational Warnings:
Do not frequently power the machine on and off.
Ensure that cable connectors do not come into contact with liquids.
VI. Accessories List
Main Unit Accessories:
Power box, printhead, guide rails, belts, ink bags, nozzles.
Tool Kit:
Ink extractor, syringe, non-woven cloth, screwdriver.
