UV Printer Electronics Software Issues 12 Articles by Symptom
Includes 2 Field Diagnosis Charts · Organized by Symptom → Hypothesis → Inspection → Solution
These are the kinds of things we hear from UV printer operators all the time.
“I turned it on but the touch panel won’t come on.”
“Every time I press the print button, the program shuts down.”
“The same problem keeps coming back no matter how many times I reboot.”

“The same problem keeps coming back no matter how many times I reboot.”
Electronics and software issues can look a lot like ink supply or print head problems when you only go by the symptoms.
Replacing parts in the wrong direction wastes both time and money.
Replacing parts in the wrong direction wastes both time and money.
Goal of this guide: Quickly distinguish electronics/software issues from other causes — and respond on the spot without unnecessary parts replacement.
✅ Who Should Read This
- Anyone whose touch panel won’t turn on after powering up, or whose program freezes mid-initialization
- Anyone whose software shuts down when the print button is pressed, or who sees double printing along the X or Y axis
- Anyone experiencing unexplained recurring symptoms that rebooting or power cycling cannot fix
- Anyone who needs to reinstall the printer program from scratch after a PC replacement
- Engineers and operators who need to quickly determine “Is this an ink/head issue or an electronics/software issue?” on the spot
⚠️ Caution
- Always uninstall the existing program before reinstalling. Skipping this step will cause conflicts.
- Without the config file (.ini), all settings will reset to defaults after installation. Always keep a backup.
- If your PC shows any signs of instability, immediately back up the ARTJET folder on the desktop — it contains everything needed for reinstallation.
🧭 Key Takeaways (5 Points)
- For electronics issues, always check in this order: power → communication → board.
- If rebooting doesn’t fix a software issue, try uninstalling and reinstalling the program first.
- Double printing must be diagnosed differently depending on whether it occurs along the X-axis or Y-axis.
- The config file (.ini) holds all your settings. Always keep a backup.
- If unexplained symptoms keep recurring, reinstalling the program is often the fastest fix.
Ⅰ. Symptom-Based Diagnosis Chart (Field Quick Reference) _ UV Printer Electronics Software Issues 12 Articles by Symptom

One-line rule of thumb:
Electronics issues tend to involve power/communication symptoms. Software issues tend to produce errors only during specific actions.
Electronics issues tend to involve power/communication symptoms. Software issues tend to produce errors only during specific actions.
| Symptom | Characteristic | Likely Cause | Quick Check | Ref. |
|---|---|---|---|---|
| Printer moves but no ink comes out | Head board LED blinking | Head Board signal fault | Check Head Board LED status | ① |
| SW settings drifting from original | Values differ from initial install | Software settings changed | Restore defaults via config file | ② |
| Touch panel not responding | Screen stays off after power-on | Touch panel board fault | Check cable connections | ③ |
| Printing starts from wrong position | Start position consistently off | SW start point setting error | Reset start point or restore config | ④ |
| SW shuts down when print button pressed | Happens every time print is attempted | Software conflict / error | Check ripping image file name | ⑤ |
| Double printing along X-axis | Left-right blur / overlap | Bidirectional pin value (offset) error | Readjust bidirectional pin values | ⑥ |
| Double printing along Y-axis | Up-down blur / overlap | Y-axis feed setting error | Re-check Y-axis feed values | ⑦ |
| Head pin value (offset) out of alignment | Subtle White/Color misalignment | Head offset setting error | Perform precision pin value tuning | ⑧ |
| White line at edge of print area | Appears regularly only at the edge | Liner scale contamination or SW setting | Clean liner scale, check settings, inspect underside of head for thread-like dust | ⑨ |
| X-axis start position keeps shifting | Start point changes with each print | Liner scale contamination | Inspect liner scale and reader | ⑩ |
| Severe Varnish banding | Countless lines on Varnish surface | Varnish lamp position / density setting | Set lamp to position 1 + density 40% | ⑪ |
| Unexplained symptoms keep recurring | Rebooting and power cycling ineffective | Accumulated software errors | Uninstall and reinstall the program | ⑫ |
Ⅱ. Cause-Type Classification Chart (For Structural Understanding) _ UV Printer Electronics Software Issues 12 Articles by Symptom
A classification chart to identify the root cause and reduce recurrence.
If the same symptom keeps coming back, organizing it by the categories below is the fastest approach.
If the same symptom keeps coming back, organizing it by the categories below is the fastest approach.
| Category | Key Causes / Components | Typical Symptom | Characteristic | Ref. |
|---|---|---|---|---|
| A. Electronics Board Fault | Head Board, touch panel board | No ink output, touch panel unresponsive | Power-related symptoms, rebooting ineffective | ① ③ |
| B. Software Error | SW conflict, accumulated errors | SW closes on print, unexplained recurring symptoms | Errors occur only during specific actions | ⑤ ⑫ |
| C. SW Settings Error | Start point, offset, config error | Wrong position printing, double printing, pin value drift | Resolvable by restoring config file | ② ④ ⑧ |
| D. Double Printing | Different causes per X/Y axis | Left-right or up-down blur / overlap | Check items differ depending on axis direction | ⑥ ⑦ |
| E. Liner Scale Contamination | X-axis position recognition error | Shifting start position, White line at print edge | Often resolved by cleaning alone | ⑨ ⑩ |
| F. Varnish Settings | Lamp position / density error | Severe banding, glossy finish not achieved | Cannot be resolved without a dedicated lamp | ⑪ |

Ⅳ. ARTJET UV Printer
After more than five years of selling and servicing ARTJET UV printers, one thing stands out above all else.
Next to product reliability, the most critical factor is accumulated troubleshooting data.
Any machine can develop problems depending on the environment, work conditions, and operator experience.
What truly matters in a production setting is not “a machine that never fails” — it’s:
What truly matters in a production setting is not “a machine that never fails” — it’s:
How quickly and how accurately you can identify and resolve the issue when it occurs.
ARTJET continuously collects and organizes real-world problem data from the field to support faster and more precise troubleshooting.
