Image-Quality Discussion

In testing, the Samsung SCX-5312F produced output displaying good printer resolution. As might be

expected (since Samsung is relatively newer to copying), copier resolution was not as good as that produced

by digital copiers tested by IATSD in the past. Overall, the unit was comparatively good at producing

halftones and fine line work.
