These adjustments could make bleed-through more susceptible for Copy/Scan output.

1. From the control panel, select Copy, Fax, Scan to Email or Scan to Network, and then select Image Adjustment.
2. Select Background Cleanup then move the slider to the left or to the right to increase or decrease the background, and then select OK. Repeat as necessary to achieve the desired output.

When duplex printing (printing on both sides), the printed area on the back of the printed page often “bleeds through” and can be seen from the front side of the page causing the copied, printed, or scanned image to appear as light colors on front page. Darker originals are more susceptible to bleed-through than originals containing light colors (pastels). To prevent the backside from being copied to the front side of the page, the background must be lightened in the settings.
