An area I highlighted with a fluorescent (or neon) marker does not appear in my scan. What should I do?

• Try using a non-fluorescent marker. This limitation occurs with some scanners that use a contact image sensor (CIS) and cannot detect fluorescent marks accurately, especially yellow marks.

  If you need to scan a document with fluorescent marks, we recommend you use a scanner with charge-coupled device (CCD) technology or a full-color contact image sensor, both of which can detect fluorescent marks. The following Epson products feature CCD or full-color CIS optics:

  • DS-30000/DS-32000
  • WorkForce DS-6500/7500/50000/60000/70000
