¶ Fault Phenomenon
- When printing gold (foil-stamp) works, one or more distinct vertical lines appear on otherwise flat areas of the print.
- After lamination, the areas corresponding to these vertical lines are not fully laminated.
¶ Cause Analysis
Ink contamination on the encoder strip
- Inside the printer, there is a transparent polymer strip called the encoder strip, which is used for precise printhead positioning.
- If the encoder strip becomes contaminated (for example, ink adhering to it during long-term printing), the printhead cannot correctly determine its position at the contaminated location. As a result, no ink is ejected at that coordinate, producing vertical lines in the printed result.
¶ Troubleshooting Steps
- Power off the printer and remove the top cover.
- Inspect the encoder strip for ink contamination.
- If the encoder strip is not contaminated, refer to https://support.eufymake.com/s/article/eufyMake-UV-Printer-E1-Encoder-Strip-Replacement-SOP
- If contamination is present, lightly moisten a lint-free cloth with alcohol and gently clean the affected area of the encoder strip.
- Reinstall the top cover of the printer.
- Print a status chart and check whether vertical lines are still present.
- If no vertical lines appear, the issue has been resolved.
