A line is visible when performing Scan to Email

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.

Solution

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

Step

Action

1

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.

2

Adjust Background Removal setting.

Notes:

  • 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.

3

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.

4

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

5

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.

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:

Step

Action

1

Launch your Internet browser.

2

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

3

Click Settings on the left-hand pane.

4

Click Email/FTP Settings.

5

Click Email Settings and do the necessary adjustments.

Manually calibrate the scanner values. This diagnostic test is used to calibrate both the black and white values for the ADF and the flatbed.

The following values can be adjusted using this menu item:

Flatbed Black – Values are -10 to 10. The default value is 0.

  • ADF Front Black – Values are -10 to 10. The default value is 0.
  • ADF Back Black – Values are -10 to 10. The default value is 0.
  • Flatbed White – Values are -10 to 10. The default value is 0.
  • ADF Front White – Values are -10 to 10. The default value is 0.
  • ADF Back White – Values are -10 to 10. The default value is 0.

To do this, follow these steps (a-e):

  • a. Navigate to Diagnostics > Scanner Calibration, and touch Scanner Calibration.
  • b. Select scanner calibration value of interest.
  • c. Select the value to be adjusted by touching it. For example:
    • To darken, increase the value upfrom 0, i.e., 4
    • To lighten, decrease the value from 0, i.e., -4
  • d. Test and view result.
    • ADF front adjustment ‑ Image-side up and touch Copy Quick Test. Compare results with the original and adjust as needed.
    • ADF back adjustment ‑ Image-side down and touch Copy Quick Test. Compare results with the original and adjust as needed.
