UV Printer Electronics Software Issues 12 Articles by Symptom
Includes 2 field-reference tables · Organized as Symptom → Hypothesis → Inspection → Solution
If you run a UV printer, you’ve probably heard comments like these:
“I turned it on but the touch panel won’t light up.”
“The moment I press print, the software closes.”
“I’ve rebooted and the same problem keeps coming back.”
“The moment I press print, the software closes.”
“I’ve rebooted and the same problem keeps coming back.”
Control board and software issues often look, on the surface, like ink supply or printhead problems.
Replacing the wrong part based on a mistaken guess wastes both time and money.
Replacing the wrong part based on a mistaken guess wastes both time and money.
Goal of this article: quickly tell control board / software issues apart from other causes, and let you respond on the spot without swapping parts unnecessarily
Who Should Read This?
- Anyone whose touch panel won’t turn on, or whose program freezes during initialization
- Anyone whose software closes on print, or who’s seeing double printing along the X or Y axis
- Anyone who needs to align the head and set up offset in the correct order after a head replacement
- Anyone dealing with unexplained recurring symptoms that persist after rebooting or power cycling
- Anyone who needs to reinstall the printer program after a PC replacement, or who needs remote support
- Engineers/operators who need to quickly tell whether an issue is ink/head-related or control board/software-related
Precautions
- Always uninstall the existing program before reinstalling. Skipping this step can cause conflicts.
- Without the config file (.ini), all settings reset to defaults after software installation. Always keep a backup.
- If your PC shows signs of instability, back up the ARTJET folder on the desktop immediately — it contains everything needed for reinstallation.
- Skipping head alignment before setting the offset means you’ll never get sharp printing, no matter how precisely you tune the offset afterward — alignment always comes first.
- When using remote support (AnyDesk), never click on ad buttons, and always approve the connection request yourself.
Key Summary (6 Points)
- For control board issues, check in the order of power → communication → board.
- For software issues that a reboot doesn’t fix, try uninstalling and reinstalling the program first.
- Double printing has different causes and checks depending on whether it’s along the X-axis or Y-axis.
- Head offset must follow this order: straight-line alignment → left/right → bi-directional → vertical.
- The config file (.ini) holds every setting you have — always back it up.
- For unexplained recurring symptoms, reinstalling the program is often the fastest fix.

One-line rule of thumb
Control board issues tend to show up as power/communication symptoms, while software issues tend to occur only during specific actions.

| Symptom | Characteristics | Likely Cause | Quick Check | Ref. |
|---|---|---|---|---|
| Print motion runs, no ink output | Head board LED blinking | Head Board signal fault | Check Head Board LED status | ① |
| SW settings drifted | Differs from initial install values | Software settings changed | Restore defaults via config file | ② |
| Touch panel unresponsive | Screen stays off when powered | Touch panel board fault | Check cable connection | ③ |
| Printing starts at the wrong position | Start position keeps drifting | SW start-point setting error | Reset start point or restore config | ④ |
| SW closes on print button | Repeats every time you try to print | Software conflict / error | Check ripped image file name | ⑤ |
| Double printing along the X-axis | Blurring/overlap left-right | Bidirectional pin value (offset) error | Readjust bidirectional pin value | ⑥ |
| Double printing along the Y-axis | Blurring/overlap up-down | Y-axis feed setting error | Re-check Y-axis feed value | ⑦ |
| Overlapping text / rough images after head replacement | Doesn’t improve even after offset tuning | Head straight-line alignment skipped | Perform mechanical H.Align first | ⑧ |
| Head pin value (offset) drifted | White/Color slightly misaligned | Head offset setting error | Run precision pin value tuning | ⑨ |
| White lines at the edge of the print area | Regular pattern, only at the edge | Liner scale contamination or SW setting | Clean liner scale, check settings, inspect for thread-like dust under head | ⑩ |
| X-axis start position keeps shifting | Start point differs each print | Liner scale contamination | Inspect liner scale and reader | ⑪ |
| Heavy Varnish banding | Countless streaks on Varnish surface | Varnish lamp position / density setting | Set lamp to Position 1 + density 40% | ⑫ |
| Unexplained recurring symptoms | Reboot / power cycle doesn’t fix it | Accumulated software error | Uninstall and reinstall the program | ⑬ |
| Alignment-test line prints with margin images | Occurs irregularly | Leftover data in flash memory | Adjust Flash before print value (3000→0) | ⑭ |
| GUI fails to initialize (Z-axis homing failure) | Power cycling / USB reconnect doesn’t fix it | USB driver (YiLi-USB3.0) missing | Uninstall and reinstall the USB driver | ⑮ |
| Need remote support but don’t know how | — | — | See the AnyDesk installation and connection guide | ⑯ |
III. Root-Cause Classification Table (For Understanding the Underlying Structure) – UV Printer Electronics Software Issues 12 Articles by Symptom
This table helps you pinpoint where the root of the problem lies, reducing repeat occurrences.
When the same symptom keeps coming back, sorting causes into these categories is the fastest path forward.

| Category | Main Cause / Factor | Typical Symptom | Characteristics | Ref. |
|---|---|---|---|---|
| A. Control Board Fault | Head Board, touch panel board, USB driver | No ink output, touch panel unresponsive, initialization failure | Power/communication-related, reboot doesn’t help | ① ③ ⑮ |
| B. Software Error | SW conflict, accumulated errors, leftover Flash data | SW closes on print, unexplained recurring symptoms, alignment line with margin images | Occurs only during specific actions | ⑤ ⑬ ⑭ |
| C. SW Setting Error | Start point, offset, config error | Wrong print position, double printing, offset drift | Often fixed by restoring the config file | ② ④ ⑨ |
| D. Double Printing | Different causes by X/Y-axis direction | Blurring or overlap, left-right or up-down | Checklist differs by axis direction | ⑥ ⑦ |
| E. Head Mechanical Alignment/Offset | Missing straight-line alignment, offset error | Overlapping text, rough images, pin value drift | Alignment always precedes offset | ⑧ ⑨ |
| F. Liner Scale Contamination | X-axis position recognition error | Start position shift, white lines at print edge | Often resolved by cleaning alone | ⑩ ⑪ |
| G. Varnish Configuration | Lamp position / density error | Heavy banding, no Glossy effect | Cannot be fixed without a dedicated lamp | ⑫ |
IV. ARTJET UV Printer
Having sold and maintained ARTJET UV printers for over 5 years, one lesson stands out above all others.
After product reliability, the most important factor is the accumulation of troubleshooting data.
Any machine can encounter issues depending on the operating environment, working conditions, and user experience.
What truly matters in a real production setting is not “a machine with zero problems” — it’s:
