A Line Is Visible when Performing Scan to E-mail

Affected products



in the title section above to see a full list of MFPs that this article applies to.

What you will see

When using the Scan to E-mail function the output has a line (could be of any color) across the page. See the following sample of scanned output.

Although the line appears in the Scan to E-mail output, there are no print quality issues shown when printing, sending fax, and performing copies. In addition, the line appears only when performing Scan to E-mail with the “Colored” or “Color” setting turned ON.

Suggested remedy

Using the printer’s Control Panel, navigate through Menu > Settings > Email Settings and do the following in order:


In the E-mail Settings, uncheck the option 'Scan edge to edge'. Perform another Scan to E-mail task and see whether the line disappears. Proceed with the next step if the line remains.


Adjust Background Removal setting.


  • A positive (+) adjustment removes more background while a negative (-) adjustment removes less background.
  • The more background removed, the more the copy of the original document becomes lighter. Start with +1 and add up as needed until the line(s) disappears while maintaining an acceptable scan quality.


Use a different output format (i.e., PDF, JPEG, TIFF, XPS).

  • Should you need to use PDF format, try switching to a different PDF version of the output.
  • If issue is only observed when output is JPEG, change JPEG Quality.


Switch to a different Content Type (i.e., Text, Text/Photo, Photo & Graphics).


If your MFP allows it, switch to a different Content Source (i.e., Color Laser, Inkjet, Photo/Film, Magazine, Newspaper, Press, Other).

Retest and if issue persists, then go to step 6.


If the current Resolution setting is 300 dpi, lower it down to 200, 150, or 75 until the line disappears while maintaining an acceptable scan quality.

You can also perform the preceding suggestions through the printer’s Embedded Web Server (EWS). To do this:


Launch your Internet browser.


Type the printer’s IP address in the address field.


Click Settings on the left-hand pane.


Click Email/FTP Settings.


Click Email Settings and do the necessary adjustments.

Should issue persist even after performing these steps, please contact Lexmark Technical Support for additional troubleshooting suggestions.
