I have this thick blurry purple lines across my pictures when scanning on a brand new v370 scanner. Any idea where it's coming from? I've cleaned the scanner glass thoroughly and the negatives are cleanenter image description here

Two possibilities:

  • The bar could be due to an optical interference pattern, where a slightly-curved glossy photo touches the glass along a line. Test this by scanning a flat or matte surface, e.g. a plain piece of white paper.

  • It could be the result of the scan-head getting stuck for a second and them jumping when it passes by the obstruction. The issue might go away if the obstruction is something like congealed lubricant or a speck of dust. Try repeated scans to see if the issue disappears.

If neither help, return the new scanner for a refund or another of the same model.

  • \$\begingroup\$ @xiota depends on seller and jurisdiction, it may be only possible to get the same model as replacement. Also, this flaw is not a common issue with all v370, just this one, so changing model wouldn't really solve anything per se, would it? \$\endgroup\$

  • \$\begingroup\$ If it's a curved negative, what would you suggest I do to straighten them out? \$\endgroup\$ Jan 29, 2019 at 14:26
  • \$\begingroup\$ Just keep it from contacting the glass -- a fraction of a millimeter is sufficient. Supporting the edges with a paper mask would do. \$\endgroup\$ Jan 30, 2019 at 1:25
