03/04/14 Properties  

Problem

Resolution change has no effect on clarity; Resolution change not detected; No visible difference in resolution; Scan resolution; Dots per inch; Scan profile resolution; Scan to PC resolution; Actual scan resolutions; Optical resolution; OptraImage; X6100; X52x; X54x; X64x; X65x MFP Family; X94x; MX51x; MX61x; MX71x; MX81x;

Solution

What you will see


When you create a Scan-to-PC profile or shortcut, the Resolution slide-bar control does not display the actual resolution in dots per inch (dpi). Click here for an illustration.
NOTE: As of 2009, all Lexmark MFPs will show the dpi value. 

 

Dots per inch values


The approximate Scan-to-PC resolutions from lowest to highest are as follows:
  • 75 dpi
  • 150 dpi
  • 200 dpi
  • 300 dpi
  • 400 dpi
  • 600 dpi

Illustration
NOTE: Actual output resolution differs by scanner machine or model type. For example, machine types 4036-304, 4036-305, and 4036-306 are 300 dpi optical scanners; however, these scanners will use interpolation in Text BW mode* to achieve 600 dpi.
*Black and white mode

 

Additional Explanation


Scan resolution considerations are influenced by the following:
  • The actual optical resolution of the scanner.
  • File size restrictions in certain environments, e.g., scan-to-Email, FTP, or PC.
  • File size versus performance.
  • File size versus color, content type, and scan depth, e.g. Color-Photo-24bit.
