Fault Phenomenon

• During crystal sticker printing, irregular patterns, streaks, or wavy lines appear.

• The printed surface is uneven, with obvious horizontal or vertical streaks.

Cause Analysis

Varnish nozzle broken needle:

•  A broken or partially clogged nozzle in the varnish channel causes uneven varnish ejection. This results in unstable ink output and visible streaks or banding on the printed surface.

Troubleshooting Steps

1. Print the nozzle status diagram, check the overall nozzle condition, and focus on the varnish nozzle section. Carefully observe for broken lines, missing segments, blurring, or uneven output.

2. If the varnish nozzle shows broken needles or abnormal output, perform Medium Clean twice, then reprint the nozzle status diagram to check whether the varnish nozzle has recovered.

3. If the nozzle status does not improve or broken needles are still present, perform a Deep Clean, then print the nozzle status diagram again for inspection.

4. If there is still no improvement, 

   1. perform an initial factory reset: eufyMake UV Printer E1 Device Unbinding & Factory Reset

   2. refill the ink, and then perform a test print to check whether the issue has been resolved.
